Volvo V70 2.4l D5 2008 ICM

ICM display / Radio Not working cold / Cuts out intermittent

This fault is usually fixed by replacing the ICM-unit, which is very expensive.
The module CAN be exchanged to a "second hand" unit from a scrap-yard, but needs to be programmed to fit Your car.
BUT in many cases the fault is due to bad / loose solder joints and resoldering can spare You from a crater in Your wallet.
CAUTION!!
Always disconnect, at least, the battery negative ( - ) pole prior to work on electrical components or parts.
Also please READ the DISCLAIMER at the bottom of the blog!

Removing the console

2 screws under the lid dampers

Removal of the whole center console is not necessary, but the front part where the display is has to be possible to tilt backwards.

The ICM unit is behind the display.

Remove the 2 screws under the console box lid dampers.

4 screws

Remove the cover around the gear lever.

It usually comes off by pushing it forward and up using a flat tool. On some models it is easier to start at the front end. Either way the cover is released by pushing it against the gear lever and at the same time bending it upward.

Covering the console edge with a carbon paper or cloth, as the lid is bent upward, saves it from scratches and/markings.

Remove the 4 screws in the corners.

READ THE TEXT PRIOR TO REMOVAL

On this model ( 2008 V70 D5 ) it can ONLY be removed starting at the TOP EDGE.

Check Your model's instructions prior to removal..
Do NOT try to remove it if you are not sure which way to start.
After removing the cover the last 2 front side screws can be removed.

Remove the 2 screws on the back side of the upper console.

Slowly and carefully tilt the console towards the gear lever.
As it is tilted the cable connectors on the back has to be disconnected. Take notes of where the go, since - hopefully - you will be putting them back..

When the console is tilted enough forward, the ICM unit cover is held in place by 4 screws.

ICM Disconnecting and re-soldering

The ICM circuit revealed

The module itself is now held in place only by it's connectors.
Carefully pull the module STRAIGHT up to disconnect it from the console. Do NOT bend or tilt the module!

Handle the disconnected module with great care.
Only holding it by the edges and whatever you do.. do NOT drop it..
Nor should the module be exposed to water, electrostatic discharges ESD.
Since this is a very expensive module, it should be cared for as such..

Check / re-solder the connecting joints of the connectors and especially the relay.

On some units, the relay has been badly placed on its soldering joints. Resulting in only partial soldering.

Refitting and testing

Refit everything in reverse order.
Remember the connectors to the console as You tilt it back in position.
Re-connect the battery negative ( - ) pole.

The display hopefully lights up and works as intended.

If so.. You just save a pile of 100 $ / € / £ bills..

If not.. the module probably has to be replaced.. and You only wasted some, though valuable, time..
