Checking Cables And Components, Infotainment Control Module (ICM)

The control module is defective if the infotainment control module (ICM) is not emitting light.

If the infotainment control module (ICM) is transmitting light, the fault is in the MOST cable for the next control module.

Check the MOST connection. Check for dirt, loose connections and damage.

Replace the MOST cable if no fault is found in the MOST terminal.

Remedy as necessary.
