Checking Cables And Components, Infotainment Control Module (ICM)

Visually check that the infotainment control module (TCM) emits light from the MOST connector.

If no light is emitted by the infotainment control module (ICM) then the control module is damaged.

If the infotainment module (ICM) does emit light, the fault lies in the MOST cable to the next control module.

Inspect the MOST connection for dirt, loose contacts and damage.

If no fault can be found in the MOST connection, change the MOST cable.

Remedy as necessary.
