These codes are generated through a communication protocol, one of the most common being J1939, which is widely used in the trucking industry.

In this blog, we will break down what these fault codes mean and how you can use them to your advantage for better diagnostics and truck maintenance. 

What are DTCs? 

DTCs, or Diagnostic Trouble Codes, are identifiers that communicate issues with a vehicle’s systems. These codes provide vital information about the source of a problem, helping you pinpoint issues more accurately. The codes are structured with three key components: SA, SPN, and FMI.

• SA (Source Address): This indicates the computer system where the fault is originating. Common examples include: 

• ECM (Engine Control Module) = SA 0 

• ACM (Aftertreatment Control Module) = SA 61 

• BCM (Body Control Module) = SA 33 

• ABS (Antilock Braking System) = SA 11 

• TCM (Transmission Control Module) = SA 3 

If you see SA 0 in a code, it typically points to the engine control module. This helps you understand which system is reporting the fault. 

• SPN (Suspect Parameter Number): This identifies the specific component or condition triggering the fault. For example, SPN 3216 refers to an issue with the Aftertreatment Intake NOx sensor, pointing to a component failure. However, it’s also important to note that some faults relate to conditions rather than components, like an operating parameter falling outside the normal range. 

• FMI (Failure Mode Indicator): FMI provides more detailed information about the type of failure being reported, further narrowing down the issue. It can indicate problems like circuit breaks, component failures, communication errors, or operating conditions beyond set limits. For example, FMI 14 signals a special failure that requires specific instructions from the manufacturer to diagnose accurately. 

Common FMI Codes and what they mean 

When diagnosing faults, understanding the different FMI codes is crucial. Some of the most common FMI codes include: 

• FMI 3, 4, 5, 6: These indicate circuit issues, such as an open circuit, short to ground, or other electrical failures. 

• Open Circuit: A broken wire or disconnected part, preventing the circuit from completing. 

• Closed Circuit: Something that should be open is now closed, leading to improper operation. 

• Short Circuit: A grounding issue, often caused by internal component failure. 

By understanding these fault codes and their meanings, you can more quickly diagnose and address problems with your truck’s systems, ensuring smoother operations and preventing unexpected breakdowns. 

Diagnostic trouble codes (DTCs) may seem complex at first glance, but once you break them down, they offer valuable insights into what’s happening with your truck. By understanding the components of the code SA, SPN, and FMI, you can easily identify and address issues, saving time and money on repairs.

With the right tools, like OTR Diagnostics, you can have these fault codes at your fingertips and stay ahead of potential issues. 

Whether it’s a wiring issue, a faulty sensor, or a communication delay between components, FMI codes help you identify the root cause. In this article, we’ll break down the most common FMI codes, what they mean, and how you can use them to take the right next step fast.

What are FMI codes?

FMI codes work alongside SPN (Suspect Parameter Number) codes to describe what type of fault occurred. While SPN tells you where the issue is, FMI tells you what’s wrong. This is crucial for determining whether you’re looking at a simple wiring issue or a deeper component failure.

Let’s look at the most common FMI categories:

Component failures & wiring issues:

These faults typically deal with physical parts like sensors, actuators, or modules and their connections.

FMI 5 – Open Circuit or Low Current

Often, it means a wire is broken or disconnected. Think of it as the truck saying, “I’m not getting power where I should be.”

FMI 7 – Not Responding or Out of Adjustment

Indicates a part is there, but it’s acting out of spec or failing to respond.

FMI 12 – Bad Component or Module

Straightforward and serious, this means a part has likely failed and needs replacement.

Tip: Component failures are often easier to diagnose because the DTC usually points directly to the failing part, reducing the guesswork.

Data communication errors (CAN System)

Your truck’s brain relies on internal communication across the Controller Area Network (CAN). When that communication lags or breaks down, you’ll see these:

FMI 9 – Abnormal Update Rate

A key system (like the VGT actuator or EGR valve) isn’t sending updates fast enough. The engine control module starts asking, “Where’s the data?”

FMI 10 – Abnormal Rate of Change

Signals data is coming in, but it’s erratic or slower than expected. For example, SPN 3216 + FMI 10 could mean a slow or stuck NOx sensor.

These issues don’t always mean the part is broken; it could be a wiring glitch, a sensor lag, or a module beginning to fail.

Condition-based failures:

Not all faults are electrical. Some FMI codes indicate that operating conditions have drifted out of range:

FMI 0 or 1 – Above or Below Expected Range

Often triggered in aftertreatment systems. For instance, SPN 3364 + FMI 1 means the DEF quality is below the acceptable level.

FMI 31 – Condition Met

A catch-all code that shows a predefined condition has occurred, like low DEF or derate mode. It’s not always a fault in the traditional sense, but it helps explain why your truck is acting the way it is.

Diagnose Smarter with OTR Diagnostics

When you pair this code knowledge with a diagnostic tool like OTR Diagnostics, you gain the power to interpret and act immediately without waiting on a dealer.

The OTR Diagnostics app doesn’t just read fault codes; it helps you understand their meaning, perform resets, and monitor active data. It’s your shortcut from “What’s going on?” to “Problem solved.”

FMI codes are more than just numbers, they’re messages your truck sends to help you stay on the road. By understanding what these codes mean and how they relate to wiring, components, or system conditions, you can make faster, smarter decisions.

When paired with a tool like OTR Diagnostics, this knowledge becomes actionable power. Instead of wasting time guessing or sitting at the dealer, you’ll know what needs attention and when to take action.

What is a turbocharger and how does it work on a semi-truck?

A turbocharger is a performance-boosting component that uses exhaust gases to force more air into your truck’s engine. More air means more oxygen, which allows your engine to burn more fuel, resulting in more power without increasing engine size. Here's how it works, step by step:

1. Exhaust gases exit the engine:

When your engine burns fuel, it produces hot exhaust gases. Instead of wasting that energy, the turbo makes use of it.

2. Spinning the turbine:

The exhaust gases flow through a turbine inside the turbocharger. As the gases pass over the turbine blades, they spin rapidly, often over 100,000 RPM.

3. Powering the compressor:

The turbine is connected by a shaft to a compressor on the other side of the turbo. As the turbine spins, it drives the compressor.

4. Sucking in and compressing fresh air:

The compressor pulls in outside air, compresses it, and forces it into the engine’s intake manifold. This compressed air is denser and contains more oxygen than regular air.

5. More Oxygen = More Power

With more oxygen entering the cylinders, the engine can inject more fuel and generate a more powerful combustion. That means more horsepower and torque, perfect for hauling heavy loads or climbing grades.

Why it matters for you and your truck:

• Improved fuel efficiency: More power from the same engine size.

• Better performance at altitude: Compensates for thinner air in high elevations.

• Greater towing capability: Essential for pulling full loads uphill or under stress.

Common signs of a failing turbocharger: 

Turbo issues can become major headaches if ignored. Here are key symptoms to keep an eye on: 

1. Power loss: A significant drop in engine power can signal turbo failure, making your truck sluggish and slow to accelerate, especially when merging or overtaking. 

2. Check engine light: If your check engine light comes on, it could indicate turbocharger problems, such as underboost or overboost conditions. 

3. Whining or whistling sound: Strange noises during acceleration, like whining or whistling, may point to damaged bearings or leaking seals in the turbo. 

4. Oil consumption and exhaust smoke: Increased oil consumption and blue or white exhaust smoke can indicate oil leaking into the exhaust system due to a failing turbo. 

5. Excessive fuel use: A malfunctioning turbo often leads to higher fuel consumption as the engine compensates for lost power. 

6. Oil leaks: Visible oil leaks around the turbocharger or housing can signal internal issues like damaged seals or bearings. 

What causes turbocharger failure? 

Several factors can cause a turbocharger to break down: 

• Wear and tear: Over time, high-speed driving and harsh conditions wear down turbo components. 

• Oil/Lubrication issues: Insufficient or contaminated oil can cause poor lubrication, leading to friction, overheating, and turbo damage. 

• Foreign objects: Dust, dirt, or debris entering the turbo can cause damage to the compressor or turbine. 

• Damaged seals: Worn-out seals can result in oil leaks, affecting turbo performance and causing engine issues. 

Can you drive with a blown turbo? 

It’s not advisable. Driving with a blown turbocharger can cause severe engine damage, reduced performance, and safety hazards. You may experience excessive oil consumption, smoke, or even engine failure. Have your turbo inspected and repaired by a professional as soon as possible. 

Stay ahead of turbo trouble with OTR Diagnostics

Catching turbocharger issues early can mean the difference between a minor repair and a major breakdown. That’s where OTR Diagnostics comes in.

Maintaining your truck's performance is crucial, and one way to ensure it stays on the road without major hiccups is by understanding and addressing fault codes as they come up. Today, we’re going to break down fault code 3255, also known as SPN 3246 FMI 0 or SPN 3246 FMI 16.

This code signals an issue with the Diesel Particulate Filter (DPF) outlet temperature sensor, which has detected temperatures exceeding the allowable limit. If left unresolved, this can lead to severe damage in your truck’s aftertreatment system. Let’s dive into what this means and how you can fix it.

What Does Fault Code 3255 Mean?

Fault code 3255, or SPN 3246 FMI 0 or FMI 16, indicates that the DPF outlet temperature sensor has recorded temperatures above the safe threshold. This sensor is part of the aftertreatment system, located at the outlet of the DPF, and it plays a vital role in monitoring the exhaust temperature. If this sensor detects a temperature higher than 1355°F (735°C) for more than 145 seconds, the Engine Control Module (ECM) steps in to prevent further damage.

Here’s what happens when this fault code triggers:

• Red stop engine lamp and malfunction indicator lamp (MIL) are disabled.
• Active and stationary regeneration of the DPF is halted.
• Exhaust gas recirculation valve operation is disabled.
• Engine torque is reduced to prevent overheating and system damage.

If the fault persists, the ECM may even shut down the engine if the engine protection shutdown feature is enabled. This fault code is serious, and immediate action is needed.

How the DPF Outlet Temperature Sensor Works

The DPF outlet temperature sensor is part of a smart system that communicates with the ECM through the J1939 data link. It continuously monitors temperatures at both the intake and outlet of the DPF while the engine is running. The diagnostic process runs constantly, except during active DPF regeneration, to ensure the outlet temperature stays within safe limits.

How to Address Fault Code 3255

When you encounter fault code 3255, it's essential to act quickly. Here's how you can clear the fault:

1. Perform a key cycle: Turn off the engine, wait for one minute, then restart it.
2. Let the engine idle for one minute.

Once this is done, the fault code status on your OTR Diagnostics tool should change to inactive after the diagnostic passes. You can also use OTR Diagnostics to clear the MIL light and check the status of any active or inactive fault codes.

Common Causes of Fault Code 3255

This fault code typically indicates that the DPF outlet temperature has reached unsafe levels. Common reasons for this include:

• Excessive engine oil or diesel fuel entering the exhaust system.
• A malfunctioning DPF outlet temperature sensor.
• A face-plugged diesel oxidation catalyst.

Addressing these issues as soon as possible is critical to avoiding further damage and ensuring compliance with emissions standards.

The Power of OTR Diagnostics

If you’re using OTR Diagnostics, you already have the tools needed to address this issue. OTR Diagnostics allows you to perform OEM fault code resets, conduct aftertreatment maintenance, and initiate regens. For those who don’t have OTR Diagnostics yet, it’s designed to give you full access to your engine’s fault code information, making maintenance easier and more efficient. This tool empowers you to stay ahead of problems before they become costly repairs.

Preventative Maintenance Tips

Addressing fault code 3255 quickly will help you avoid major downtime and expensive repairs. Regular maintenance of your truck’s aftertreatment system and using high-quality diesel exhaust fluid (DEF) are critical steps in preventing issues like this from arising.

Fault code 3255 is a reminder that staying on top of your truck’s performance is essential. By understanding what’s going on behind the scenes and using the right tools, you can keep your truck running smoothly and efficiently, saving you time and money in the long run.

DPFs are crucial for reducing harmful emissions, but they can become clogged over time, leading to decreased engine performance and increased fuel consumption.

Monitoring your DPF soot/ash levels makes keeping your truck running in optimal shape easier and effective. Eventually your DPF soot/ash level will get to the point of putting your truck into a derate. To address this issue, many mechanics and fleet managers turn to Forced DPF Regeneration (Regen), a process made easier with the help of advanced diagnostic tools like OTR Diagnostics. 

In this detailed guide, we will explore the concept of Forced DPF Regeneration, its significance, and how you can perform it using OTR Diagnostics.  

What is a Forced DPF Regen?

Diesel Particulate Filters (DPFs) are designed to capture and store soot/ash particles produced during the combustion process in diesel engines. However, over time, these filters can become clogged with soot/ash, causing a variety of issues. To prevent these problems and keep the engine running efficiently, performing a regular DPF regeneration is essential. 

These issues may include:   

• Reduced engine power 
• Increased fuel consumption 
• Excessive emissions.  

What are the two main types of DPF regen for a semi-truck? 

DPF Regeneration or DPF Regen is a process in which the accumulated soot/ash in the filter is burned off, leaving behind only ash. There are two main types of DPF regeneration: 

• Passive Regeneration: This occurs naturally when the exhaust gases reach a high enough temperature to burn off the soot in the filter. This typically happens during highway driving when the engine operates at a consistent and high load. 
   
• Active or Forced Regeneration: In this method, the engine control unit (ECU) initiates the regeneration process by injecting extra fuel into the exhaust stream to raise the temperature in the DPF, allowing the soot to be burned off. Active regeneration is necessary when passive regeneration is not occurring frequently enough, often due to short trips with low exhaust temperatures. 

What is the significance of a forced DPF regen? 

A forced DPF regen is crucial for several reasons: 

• Preventing Engine Damage: A clogged DPF can lead to backpressure in the exhaust system, which can cause severe engine damage if left untreated. 
• Emission Compliance: Regulations around diesel engine emissions are becoming increasingly stringent. Regular DPF regens ensure compliance with emission standards. 
• Maintaining Fuel Efficiency: A clean DPF helps your engine operate efficiently, reducing fuel consumption and operational costs.

In this beginner's guide, we'll take a closer look at what a DPF system is, how it works, and how to care for it. 

What is a Diesel Particulate Filter (DPF). 

A Diesel Particulate Filter (DPF) is an essential component in modern diesel vehicles, designed to reduce harmful emissions from exhaust gases. For some semi-truck drivers, the DPF is a nuisance and is just a money pit.

As we know, your DPF filter is part of the emissions control system and plays a vital role in cleaning up the exhaust before it exits the tailpipe. DPF systems are most commonly found in diesel-powered cars, trucks, and heavy machinery. 

How Does Your DPF System Work Inside Your Semi-Truck? 

• Trap and Collect Particulate Matter: The primary function of a Diesel Particulate Filter (DPF) is to trap and collect soot and other particulate matter produced during the combustion process. These particles are tiny, often measuring less than one micron in size. 
• Ash Accumulation: Over time, even after a forced regen, some particulate matter remains in the DPF as ash. Ash is non-combustible and cannot be removed through regeneration. It necessitates periodic maintenance, which may involve replacing the DPF. The OTR Diagnostic app can monitor in real time you're soot level letting you know when that level is high.  
• Regeneration: Over time, the trapped particulate matter accumulates in the Diesel Particulate Filter (DPF), leading to reduced exhaust flow and potential performance issues. To prevent this, DPF systems have a process called regeneration. There are two main types of regeneration: 
• Passive Regeneration: This occurs naturally when the exhaust temperature is high enough to burn off the trapped particles, converting them into ash. This process typically happens during highway driving when the exhaust system reaches the required temperature. 
• Active Regeneration: In cases where passive regeneration doesn't occur frequently enough (e.g., during short city trips), active regeneration is initiated by the vehicle's computer. It injects extra fuel into the exhaust, increasing the temperature and burning off the accumulated soot. 
• If neither active nor passive regenerations are successful, a forced regeneration may be necessary. This can be done using the OTR Diagnostics app directly from your phone. These types of dealer level commands are just one of the many reasons semi-truck drivers are choosing OTR Diagnostics over OEM software.  

How to maintain your (DPF) Diesel Particulate Filter System. 

• Drive for Regeneration: To ensure your Diesel Particulate Filter (DPF) system functions properly, it's essential to drive your vehicle under conditions that promote a regeneration. Regularly taking your diesel vehicle for longer drives, especially on highways, helps maintain a clean DPF. We all know that forcing a regen is not always convenient. Having a tool that sends that command anytime you want is essential for an owner operator.  
• Use the Right Fuel: High-quality diesel fuel with low sulfur content is crucial for DPF health. Low-quality fuel can lead to more frequent regeneration cycles and increase ash/soot buildup. 
• Avoid Short Trips: Short trips with frequent stops and starts don't allow the exhaust system to reach the necessary temperatures for effective passive regeneration. Whenever possible, plan your trips to include some highway driving. 
• Follow Manufacturer Recommendations: Consult your trucks’ owner's manual for specific maintenance recommendations related to your DPF system. This may include service intervals and procedures for ash cleaning or DPF replacement. 
• Monitor Warning Lights: Modern vehicles have sensors that monitor DPF status. If warning lights related to the DPF system appear on your dashboard, it's essential to address the issue promptly to avoid costly repairs. 
• Professional Maintenance: Periodic inspections by a qualified mechanic can help detect and address Diesel Particulate Filter (DPF) issues early. Regular maintenance can extend the life of your DPF and ensure your vehicle remains compliant with emissions standards. With OTR Diagnostics you can monitor your trucks’ health in real-time and potentially fixing the issue yourself.  

Understanding your Diesel Particulate Filter (DPF) system is really important for the proper functioning of your semi-truck and for complying with emissions regulations. By following these guidelines and taking proper care of your DPF system, you can ensure that your rig remains efficient, eco-friendly, and reliable for years to come.

These OEM software solutions provide in-depth diagnostics and access to manufacturer-specific systems and data but can be costly, complicated to use, and limited to particular semi-truck brands. 

Telematics devices, like those used in fleet management, provide data on truck performance, location, and driver behavior. While they offer valuable insights for fleet managers, they may not offer detailed diagnostics for specific engine issues. 

By investing in a diagnosis tool like OTR Diagnostics and learning how to use it, you can often identify common issues like engine trouble codes, sensor malfunctions, and even send dealer level commands like a forced regen.

This knowledge can help you decide whether the repair is something you can handle on your own or if it's best left to a professional. 

Misconception #2: The Dealers Are the Only Source of Genuine Parts for Your Semi-Truck. 

Another misconception is the belief that only dealerships can provide genuine and high-quality replacement parts for your semi-truck.

While dealers do stock OEM (Original Equipment Manufacturer) parts, there are reputable aftermarket suppliers and online stores where you can find compatible parts at competitive prices. These parts can be just as reliable and may offer cost savings compared to dealership prices. 

Purchasing OEM semi-truck parts from a third-party online retailer offers several advantages to both individual truck owners and fleet managers.

First and foremost, it often results in significant cost savings, as third-party vendors can negotiate competitive prices and pass those savings on to customers. Moreover, these online platforms provide a wide selection of genuine OEM parts, ensuring the highest quality and compatibility with the specific make and model of the truck.  

This diversity makes it easier to find the right part quickly, reducing downtime and increasing operational efficiency. Additionally, many third-party retailers offer convenient shipping options, further enhancing the convenience of sourcing essential components.

Ultimately, choosing to buy OEM semi-truck parts from a trusted online source allows businesses and independent drivers to maintain their vehicles with confidence, ensuring optimal performance, safety, and longevity. 

Misconception #3: Is It True That DIY (Do It Yourself) Semi-Truck Repairs Are Always Risky? 

Another common misconception is that DIY semi-truck repairs are always risky and more likely to cause further damage.

While there are certainly repairs and maintenance tasks that should be left to experienced professionals, many routine maintenance and minor repairs are well within the capabilities of the average semi-truck owner. 

By educating yourself about your specific truck model, watching instructional videos, and using reputable diagnostic tools like OTR Diagnostics, you can safely tackle tasks like oil changes, air filter replacements, brake pad replacements, forced regens, reset fault codes, diagnose engine issues, and even some electrical repairs.

Just be sure to follow safety precautions, use the right tools, and take your time to ensure the job is done correctly. 

Taking the DIY route not only empowers owner-operators like yourself to save money but also fosters a deeper connection with your rig. By actively participating in the maintenance and repair process, you can gain a better understanding of your truck's inner workings and potentially identify issues before they become major problems. 

Moreover, the sense of accomplishment that comes from successfully completing a DIY repair can be immensely satisfying, making it a rewarding endeavor for those willing to invest the time and effort into mastering these skills.

So, while professional assistance is crucial for complex repairs, DIY truck maintenance offers numerous benefits and can be a valuable skill that could save you time and money on dealer and tow fees.  

Misconception #4: Is It True That Dealerships Offer the Best Prices for Semi-Truck Parts? 

Whether dealerships offer the best prices for your semi-truck parts is a question that often haunts owner-operators and fleet managers. While dealerships do provide a certain level of convenience, they may not always offer the most competitive prices when it comes to purchasing semi-truck parts.

The decision of where to buy these parts often depends on various factors, including the specific part needed, budget constraints, and the urgency of the repair or replacement. 

Dealerships typically carry genuine OEM (Original Equipment Manufacturer) parts, which are specifically designed for the make and model of your semi-truck. These parts are known for their quality and compatibility, ensuring a seamless fit and functionality.

However, this quality often comes at a premium price. The overhead costs of operating a dealership, including maintenance, staff, and showroom expenses, can contribute to higher prices for their parts.

Additionally, the convenience of having immediate access to parts and expert advice from dealership staff may justify the higher costs for some truck owners. 

On the other hand, alternative options for sourcing semi-truck parts include independent truck part suppliers, salvage yards, and 3rd party online retailers.

These sources may offer a broader selection of both OEM and aftermarket parts, and they can often provide competitive pricing. While aftermarket parts may not have the same level of brand recognition and quality assurance as OEM parts, they can be a cost-effective solution for many owner-operators. 

To determine whether a dealership offers the best prices for semi-truck parts, it's crucial for semi-truck owners to weigh your priorities. If time is of the essence and quality is non-negotiable, dealerships may be the go-to choose.

However, for those of you looking to balance cost-effectiveness with adequate quality, exploring other options, including independent suppliers and online marketplaces, can be a good approach.

In any case, conducting research, comparing prices, and seeking recommendations from fellow truck owners can help in making an informed decision that meets your budget.  

Misconception #5: Are DIY Repairs More Time-Consuming Than Taking Your Semi-Truck to a Dealer? 

For many semi-truck owners, the prospect of DIY repairs can seem time-consuming. It's true that tackling certain repairs may take a bit longer if you're not an expert, but the time and effort invested in learning and performing these tasks can be a cost-effective and educational choice.

Furthermore, numerous routine maintenance activities, such as oil changes and air filter replacements, can be completed fairly quickly with practice. Achieving a sense of satisfaction from a job well done can also be a rewarding experience. 

While it's undeniable that some truck repairs, especially those involving intricate engine or transmission issues, demand specialized knowledge and tools, not all maintenance tasks and repairs fall into this category.

Diligent truck owners equipped with the right tools and guidance can often manage routine maintenance, inspections, and minor repairs. Establishing a regular maintenance routine and promptly addressing issues can help detect problems early and avert major breakdowns. 

Conclusion 

It's essential to dispel the common misconceptions about DIY truck repairs. While dealerships have their place and can be a reliable source for complex or warranty-related repairs, owner-operators like yourself not feel obligated to rely solely on them.

Armed with the right tools, knowledge, and resources, many semi-truck repairs and maintenance tasks can be successfully completed by you the owner, saving time and money in the process.

Remember to always prioritize safety and consult with professionals when in doubt, but don't underestimate your own capabilities when it comes to keeping your semi-truck in top shape. 

These details of your aftertreatment rival advanced OEM (Original Equipment Manufacturer) dealership software, far exceeding your average handheld scan tool.

OTR Diagnostics helps identify issues and provides insights into semi-truck performance, ultimately saving you, the owner-operator, time, and money.

In this blog, we will explore advanced tips to help you maximize the benefits of your OTR Diagnostics tool. 

How to Read & Understand Semi-Truck Fault Codes: OTR Diagnostics

Fault codes are essential to know and understand because they tell you exactly what is wrong with your semi truck. Especially when your Check Engine Light, MIL light, or Stop Engine Light is flashing.

Once you connect OTR Diagnostics to your semi-truck, at the bottom of the screen, you will see a tab that says, "Fault Code." Now is OTR Diagnostics' time to shine. In the fault code section, you will see that it is sectioned off by the different chassis of your semi truck.

The sections are “Engine,” “Transmission,” “Cab Controller,” “ABS system,” etc. Double click on each fault code to view more advanced information on them.  

Jason Chise, CEO and Founder of OTR Performance, makers of OTR Diagnostics, mentioned during a podcast that "We want to make sure that we are empowering you, the owner-operator, with the easy-to-read information so that you know exactly what's going on with your semi truck and see if it's a repetitive issue." 

Not only can you view the fault codes, OTR Diagnostics gives you the ability to print or share that data. Why is that important to you? You are able to see if a fault code happens again. All your data is stored in your history. 

Storing Fault Code, Forced Regens, and All Semi-Truck Data History in the App. 

The "History" feature in OTR Diagnostics captures all your fault codes and everything you have done inside the OTR Diagnostic App, along with sending commands.

If you were to reset a fault or initiate a forced regen, that information will be logged into your OTR Diagnostics app on your android or iPhone for future viewing.

If you perform a forced regen, all that data will be logged in the app, along with information like how long it took. All this information is stored safely on the cloud. You can search all your history.

This is important if you are chasing down fault code that keeps popping up which could potentially turn out to be a ghost code.

Why Is Capturing the History of What You Do Inside the OTR Diagnostic App Important? 

You are able to access your semi-truck diagnostic info any time, even when you're not connected to your truck. Having the history stored directly on the OTR Diagnostic app gives access to easy to read and understand data.

Commands like resetting fault codes, along with forced regens can be very helpful when diagnosing the problem.

Knowing when and how these issues occur can help you determine if you are able to fix the problem on your own or if you must take it into the shop to have it professionally fixed.  

For example, you are driving in an area in the mountains and are climbing up a steep grade. Every time you do this, a fault code appears.

Having that information about the when and where that fault code appears on hand along with the ability to share that info with a tech can speed up the process or eliminate the need to take your truck in at all.

Also, history can play an important role when selling your truck. Having a detailed list of the fault codes and any issues your truck had can make the sale of the truck a lot easier.  

OTR Diagnostics Has OEM Level Commands for Your Semi-Truck. 

OTR Diagnostics makes advanced diagnostics amazingly simple for you. There are 3 main sections: Reset Fault Codes, Reset Aftertreatment, and Forced DPF Regens. 

Reset Fault Code Menu: Depending on your truck, you may have a subset of fault codes. 

Reset Aftertreatment: Every engine is different depending on your engine configuration. 

Keep in mind that with some commands, you may be required to do extra tasks, such as driving with a heavy load for 30 miles to reset a fault code. OTR Diagnostics makes this easy for you to comprehend and perform.

The commands are the same as the dealer would use, they just make it easy for you to view and use. 

Forced DPF Regens: This is going beyond your standard regen. It is different from driving (passive regen) or parked regen (active regen). This regen is the same command that is done at the dealer level.

OTR Performance took a complicated process and simplified it for you. Not only does the app track the number of regens, but it also records the amount of time it took to regen. Make sure you are in a safe place to perform a regen. 

How Long Does a Forced Regen Take to Complete on a Semi-Truck?

On average, a forced regen takes anywhere from 30 to 90 minutes to run, with the sweet spot being 45 to 60 minutes. Every manufacturer's time is different. Some regens are based on how much soot is on your DPF filter.

If you are doing a lot of light loads and city driving, a regen may take longer because of where and the way you are driving. “Our recommendation is doing a forced regen every 2-3 weeks.” says Jason Chise. “This ensures your system is running at tip-top shape."

You do not want to be stuck in traffic or at a delivery where it is not convenient, or you are unable to stay parked to perform a regen.” 

What Is the Importance of Performing Regular Regens on Your Semi-Truck? 

Doing a DPF regen helps with your DEF (Diesel Exhaust Fluid) fluid consumption. By performing regular DPF regens, you can prolong the number of times you will need to fill up your DEF fluid. Your system will be cleaned.

Every time you are initiating a forced DPF regen, you are putting more fuel into your exhaust system to burn more soot. The result is more power and better drivability for your truck.

OTR Diagnostics enables you to control when and where you can perform a forced regen, making your semi-truck more reliable and efficient. 

Why Is Leveraging OTR Diagnostics Live Data Important for an Owner-Operator? 

One of the most important reasons live data is important for an owner-operator is the fact that you can monitor your truck's health in real time. You can view functions like soot level, NOx sensor information, and the specific vitals on what is going on during a regen, especially with exhaust temperatures.

Live data is important to view to help diagnose serious issues you may have with your semi-truck. OTR Diagnostics displays live data differently depending on your engine, make, and model.

If you are connected to a Volvo, Cummins, or Paccar, OTR Diagnostics may display that information differently. 

Regularly Update Your OTR Diagnostics Software 

Just like any other software, OTR Diagnostics tools receive updates to improve performance and compatibility. Regularly check for updates and install them promptly.

Staying up to date ensures that your OTR Diagnostics tool can effectively diagnose and troubleshoot the latest vehicle models and systems. 

OTR Diagnostics tools are essential for maintaining the performance and safety of heavy-duty semi truck vehicles. By implementing these advanced tips, you can make the most of your OTR Diagnostics tool and enhance your ability to diagnose and troubleshoot issues effectively.

Now that you have the power of OTR Diagnostics in your hand, it is time to fully understand and utilize its full capabilities.

Put yourself in the shoes of a semi-truck driver cruising through the desert with no help for miles, wouldn’t you want to make sure your truck is running perfectly? That’s what having control over your semi-truck's diagnostics can give you!  

While traditional diagnostic tools have been in use for years, new advances in technology with heavy-duty truck diagnostics have emerged as a promising alternative to expensive OEM software.

In this blog, we will compare OTR Diagnostics with other semi-truck diagnostic tools, highlighting their features, benefits, and limitations.  

OTR Diagnostics: A Brief Overview of the Benefits 

OTR Diagnostics is a recent innovation in the world of semi-truck maintenance. With OTR Diagnostics, it goes beyond your typical handheld scan tool. You can read information at a dealer level and reset fault codes from your mobile device!

Whether you have an iPhone or Android, the OTR Diagnostics app will work with both. Plus, OTR Diagnostics gives you access to vital information about fault codes, their causes and more.

You can even send dealer level commands like, reset fault codes, reset aftertreatment, and initiate a forced DPF regen.

Unlike traditional diagnostic methods that require your truck to be stationary in a repair shop, OTR Diagnostics allows for real-time monitoring and troubleshooting while you're on the road.

Other Semi-Truck Diagnostic Tools   

Before diving into the comparison, let us briefly examine some of the traditional diagnostic tools commonly used in the trucking industry.

There are a bunch of heavy-duty truck diagnostics that are able to work on your semi-truck. They could be called your premium aftermarket diagnostic tools that claim to work on all makes and all models.

More than likely these types of diagnostic tools may require you to purchase a powerful laptop, a special adaptor, and license in order to support the software.

Purchasing one of these premium aftermarket tools may make sense if you own a fleet or a number of trucks, but for the one truck, owner-operator, or small fleet it makes more sense to go with a tool that requires less startup cost, and that could work from your phone.  

Handheld Diagnostic Scan Tools:

Handheld scan tools are portable devices used for viewing fault codes and basic diagnostic information from a semi-truck's engine. They are widely available and relatively affordable but may have limitations in terms of comprehensive diagnostics. They also have a history of not living up to the functions that are promised.  

Diagnostic Software:

Many heavy-duty truck manufacturers offer diagnostic software packages that are specific to their vehicles. These OEM software solutions provide in-depth diagnostics and access to manufacturer-specific systems and data but can be costly, complicated to use, and limited to particular semi-truck brands.

Each manufacturer has their own software. Paccar (Davie4), Volvo (Premium Tech Tool), Cummins (Insite), Detroit Diesel Diagnostic Link (DDDL), Isuzu (IDSS), Hino (DX2).

More than likely they come with an expensive start-up cost consisting of an expensive and powerful laptop to run the software, subscription costs, and time put in for training you and your staff.  

Telematics Systems:

Telematics devices, like those used in fleet management, provide data on truck performance, location, and driver behavior. While they offer valuable insights for fleet managers, they may not offer detailed diagnostics for specific engine issues.

What are the differences between OTR Diagnostics and other heavy-duty truck diagnostic products?

Real-Time Monitoring:

OTR Diagnostics excel in real-time monitoring, as they collect data as your truck is running. With live data, you will know the moment something goes wrong along with a detailed explanation of what the issue is.

This way, you are more prepared to deal with the issue, possibly saving you time and money on tow and dealer fees. When you are traveling down the road alone, and you run into an issue, you want to use a product that you trust and is trusted by 1,000’s of truckers.

Along with possible incompatibility with your rig, traditional tools typically require the truck to be stationary for diagnostics.  

Data Depth and Complexity:

OTR Diagnostics can offer deep insights into your truck's systems, including engine performance, emissions, and more. Traditional tools vary in their capabilities, with manufacturer-specific diagnostic software providing the most comprehensive data for specific truck makes and models.  

How Much Do Truck Diagnostic Tools Cost?

OTR Diagnostics involves an initial investment, including hardware and software subscription fees. However, that amount is a drop in the bucket compared to what you would pay for dealer and tow fees.

It will also save you money in the long run by preventing unexpected breakdowns. Other tools vary in cost with subscriptions and hardware cost. Most of which are really pricey and complicated to use.

OTR Diagnostics takes advantage of using your phone to monitor your truck's diagnostics.  

How Accessible are the Tools?

OTR Diagnostics turns your phone into a powerful truck diagnostic tool. Making it ideal for owner operators like you.  

Traditional tools often require physical access to the truck, along with it being stationary which can be challenging for long-haul owner operators.  

OEM software requires a laptop to be able to use it. What happens if that laptop dies on you? Your truck is in derate, you have a fault code, now you don’t have an extra back up tool to see if you can make it or if you need to replace a sensor before you are scheduled to go out.

You don’t want to be stuck with only one diagnostic tool, it’s that important. If you use that tool one time to save one load, then it’s worth it.   

Are Diagnostic Tools Compatible with My Truck?

Check if your truck is OTR Diagnostics Compatible

OTR Diagnostics is compatible with various truck makes, models and engine types, offering versatility and compatibility across a broad range of heavy duty vehicles. Traditional tools may be limited to specific truck brands or models. 

Do you need an OEM diagnostic tool if you are an owner operator? 

They are going to give you premium level access on your truck. Do you need that level of diagnostics? Probably not.

Did you know that every OEM software requires training. “The moment you plug in that OEM software, I guarantee you're going to have issues. It’s just the way it is”, says Jason Chise, CEO and founder of OTR Diagnostics in an interview.

“It works one day, and then doesn’t the next. You’re wasting a ton of time trying to get the software to work.” 

You have an ELD, do you still need to get a Diagnostics Tool? 

The short answer is YES! Your ELD is a tool to manage electric logs, the port its connected to doesn’t give you access to the information to the diagnostic capabilities.

They don’t require you the dealer level access. A lot of times your semi truck will throw a generic code, and you will need to dive deeper into the issue to find out what the root cause is.

You want that peace of mind that you can continue to on your journey, or you will need to take it to a shop.  

Make sure to do your research when choosing the right truck diagnostic tool: 

It’s really a great idea to do your research as to what your needs are before purchasing a diagnostic tool for your semi truck. “I wouldn’t want to plug a tool into my truck that isn’t designed for it because that tool may cause damage.” says Jason Chise.

Which would make a person think twice about plugging in any third-party hardware that isn’t made for your truck into your truck. Don’t purchase something that is more than what you need.

You can waste time and money trying to figure out how to work the program. Make sure you are doing your research and checking the reviews before purchasing.

Buyer beware, some diagnostic companies make claims that they are compatible with all makes and models of trucks but in reality, are not.   

Why aftermarket diagnostic tools are the perfect solution for owner operators:

The aftermarket software is a perfect solution to the OEM software issue. Diagonostic tools like OTR Diagnostics represent a significant advancement in the trucking industry, offering real-time monitoring and in-depth diagnostics while the truck is on the road.

Plus, having the ability to view live data, read and reset fault code history is a huge advantage for owner operators.

Jason also said, “If it’s my business, I want to be in control of my vehicle, and I want to be in control of my diagnostics.” The choice between OTR Diagnostics and other tools depends on your specific needs, budget, and the types of trucks you own.

For instance, if you own a Volvo you would need that specific software. In some cases, a combination of both OTR Diagnostics and traditional OEM diagnostics can provide a comprehensive solution for semi-truck maintenance and repair in a technician setting.

Staying informed about the latest developments in diagnostic technology is essential for making informed choices in the ever-evolving world of semi truck diagnostics.

Take your diagnostics seriously, don’t let others dictate when and how your truck is serviced. Get the power over your truck's diagnostics in your own hands. You can start by learning more about OTR Diagnostics here.

What Are the Costs of Parts and Labor for Semi Trucks?

One of the biggest expenses you will encounter when getting your rig repaired is the cost of parts and labor. Your truck is likely equipped with a complex engine, transmission, and specialized components like your DPF System, all of which can be expensive to replace or repair. Skilled technicians are required to diagnose and fix these issues, and their time and knowledge doesn’t come cheap.  

Additionally, sourcing parts for your truck can be challenging, especially for older models. Sometimes, parts must be custom-made or shipped from specialized suppliers, driving up costs further. 

How Costly Is Downtime for a Semi Truck Driver?

When your rig is in the shop for repair, it's not on the road earning you money. Plus, you could be stuck in the middle of nowhere at the mercy of the shop or dealer you're at. Downtime can cost you a lot of money. Now times that by 10 for trucking companies, as they miss out on potential revenue while the truck is out of commission. To minimize downtime, many trucking companies invest in maintenance, diagnostic tools and preventative measures to catch issues before they become major problems. 

What Is the Cost of Towing and Transportation When You're Broken Down

If your rig breaks down on the road, it often requires specialized towing services to get it to the repair facility. This can be an unexpected and hefty expense. The worst part is you are at the mercy of the towing company, which always equates to more money.  Furthermore, if the truck needs to be transported to a specialized facility, the costs can skyrocket. Having the right tools to get you out of a pinch like our OTR Diagnostics Tool cannot only save you time and money, it also gives you peace of mind.  

What Happens When You are Not Environmental Compliant

Environmental regulations have become increasingly stringent, and your rig must meet specific emissions standards. Repairing or upgrading exhaust systems and other components like your DPF Filter to meet these standards can be costly. Non-compliance can result in fines, further adding to the financial burden. 

New Technology and Diagnostics for You and Your Rig

Modern semi trucks are equipped with advanced technology and diagnostic systems to monitor engine performance and other critical functions. While this technology is essential for efficiency and safety, it also adds to your repair and maintenance bill. Highly specialized equipment and software are required for diagnostics and repairs, and technicians need training to use them effectively. Not all diagnostic software needs a specialized technician to use it. The OTR Diagnostics Tool gives you the power to diagnose your own rig from your cell phone.  

Why Preventative Maintenance is so important for Owner Operators

What are the Real Costs of Repair

Lets face it, everything on your truck is big, including the cost of repairs. This directly impacts both the bottom line of fleet companies and the livelihoods of independent owner-operators. From parts and labor to downtime and transportation expenses, there are numerous factors to consider. While it's impossible to eliminate all repair costs, proper maintenance and proactive measures can help minimize them.

If you're on your own and not a part of a fleet, then being your own mechanic will benefit you. When you possess the skills and proper tools to diagnose and address common issues, not only can you cut costs, but you’ll be also able to perform heavy duty DIY repairs on your own!  

Doing routine tasks like changing oil, replacing filters when warning signs are going off because it may be a clogged DPF, fixing fault codes, and inspecting brakes saves money when done by yourself. Moreover, you gain the flexibility to shop for parts, potentially finding better deals than a traditional repair shop would offer. These cost savings add up and impact on your bottom line.  

Why Your Downtime as a Truck Driver Can Be a Major Setback. 

Downtime because of mechanical issues or even worse, a Derate, can be a major setback in the trucking industry, potentially costing you both time and money. Like we said before, if you are a company driver, then being your own mechanic may not benefit you. When you fix your own truck, you can reduce disruptions by dealing with problems promptly.  

Instead of waiting for a repair shop appointment, you can fix issues right away. This will help you get your semi-truck back on the road faster. You can adjust your maintenance schedule to match your workload, so your truck is in great shape when you need it.  

Plus, you may not have to get your truck insurance involved in the process. This proactive approach can help you meet delivery deadlines and maximize your earnings.  

How to Become a Self-Reliant Owner-Operator Truck Driver? 

Self-reliance is a prized trait in the world of owner-operator trucking. You are responsible for your business's success. Being able to handle your truck's maintenance and repairs makes you more independent. Plus, you are able to be more proactive with the maintenance of your truck by performing annual inspections on it.  

As an independent semi-truck mechanic, you rely less on repair shops or roadside assistance services. Being independent saves time, money, boosts confidence, and prepares you to face challenges directly. Being skilled sets you apart and builds your reputation as a capable and independent owner-operator in the industry. Your reputation is more important than ever because of the industry-wide driver shortage for independent and large trucking companies.  

How to Improve Your Safety as a Owner-Operator Independent Driver. 

Safety is important in trucking. Maintaining and fixing your semi-truck helps make driving safer. Regular checks and quick fixes can stop big and dangerous problems from happening on your trips.  

Knowing your truck and trailer inside and out enables you to identify safety concerns before they become critical. This not only safeguards you but also ensures the safety of other truck drivers sharing the road with you. Being a good semi-truck mechanic saves lives and improves the reputation of the trucking industry.  

Is Being Your Own Semi Truck Mechanic as an Owner-Operator Worth It? 

Becoming an owner-operator truck mechanic comes with distinct advantages, including cost efficiency, minimized downtime, increased self-reliance, and improved safety. While it requires an investment in time and learning, the benefits far outweigh the initial effort. Whether it's worth it depends on your goals and preferences. By taking charge of your semi-truck's maintenance and repairs, you can make more money and be a confident owner-operator in the world of long-haul semi-trucking.

As we cross paths with these giants of the road, let us remember to extend a nod, a wave, or even a moment of recognition – these small acts can make a world of difference in acknowledging their indispensable role in our lives.  

As the dog days of summer approach, extremely high temperatures, especially during these summer months, can have various impacts on a heavy duty truck, potentially leading to mechanical breakdowns if not effectively managed. This is a potential danger if your truck is down due to a malfunction or fault code that has appeared.

Top 8 Most Common Heavy Duty Truck Failures Caused by Heat!

1. Engine Overheating

This is the most common heat-related issue. If a truck's cooling system isn't maintained properly, the engine can overheat, potentially leading to a breakdown. Factors such as low coolant levels, a malfunctioning thermostat, or a faulty water pump can contribute to engine overheating.

2. Tire Blowouts

Heat can cause the air inside the tires to expand, which increases the pressure inside the tire. Overinflated truck tires are more susceptible to punctures and blowouts, especially when the road surfaces are hot. Tread separation is also more likely to happen in hot conditions.

3. Battery Failure

High temperatures can lead to faster evaporation of the battery fluid, leading to corrosion on terminals and connections. This can eventually cause your heavy duty truck battery to fail.

4. Fuel System Issues

High heat can cause the fuel to evaporate at a faster rate, and it can cause issues with the fuel system. This can lead to lower fuel efficiency and potential engine issues.

5. Oil Viscosity and Lubrication

High temperatures can decrease the viscosity of the engine oil, affecting its ability to lubricate the engine effectively. This could lead to increased wear and tear in the engine components.

6. Cooling System

The cooling system in your heavy duty truck works harder during hot weather to keep the engine temperature under control. If there are any issues with the radiator, coolant, hoses, or fans, these are likely to become apparent when the weather is hot.

7. Air Conditioning System

High temperatures put a significant load on the air conditioning system. Any deficiencies in the system, including low refrigerant levels or leaks, can lead to a lack of cool air when it's most needed. You do not want to be stranded in your truck without air conditioning.

8. Aftertreatment System

The aftertreatment system in a heavy duty truck is designed to reduce harmful emissions and meet environmental regulations. This system often includes components like a Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR), and a Diesel Oxidation Catalyst (DOC). Heat can have several effects on these components.

How Can Heat Effect a Regen? 

You now know our top 8 most common fails in a heavy-duty truck due to heat. We also feel it is important for you to know that high ambient temperatures can also affect the Diesel Particulate Filter (DPF) regeneration system of your truck. The DPF regeneration system is designed to burn off the soot trapped in the filter, turning it into ash. This process, known as regeneration, is essential for maintaining the engine's performance and fuel efficiency and meeting emission standards. The last thing you want is to be in a derate and have to call a tow!  

However, in extreme heat conditions, the DPF regeneration process might be impacted in the following 6 ways:

1. SCR System

The SCR system uses a urea-based solution (Diesel Exhaust Fluid or DEF) to reduce NOx emissions. The DEF can freeze at temperatures below 12 degrees Fahrenheit and decompose at extremely high temperatures, impacting the SCR's functionality.

2. DOC

The Diesel Oxidation Catalyst works at high temperatures to oxidize carbon monoxide and hydrocarbons into carbon dioxide and water. If the exhaust temperature is too low, it will not work efficiently. On the other hand, excessive heat can cause thermal degradation of the catalyst.

3. Thermal Stress

The aftertreatment system components are made of materials that can withstand elevated temperatures. However, fluctuations between high and low temperatures (thermal cycling) can cause thermal stress, leading to cracks and component failure.

4. Coolant Leaks

In some designs, the aftertreatment components are cooled by the engine's coolant. Any heat-related issue causing a coolant leak can therefore affect the aftertreatment system's performance.

5. Engine Overheating

When the engine runs too hot, it can affect the exhaust temperature and pressure, disrupting the balance required for the aftertreatment system to function properly.

6. DPF Regeneration

The DPF traps particulate matter (soot) from the exhaust. For the DPF to clean itself or regenerate, it needs to reach an elevated temperature (around 1100 degrees Fahrenheit). In normal operation, heat is beneficial for this process. However, excessive heat due to faulty injectors, turbochargers, or EGR systems can cause uncontrolled regeneration or even damage to the DPF.
