Checking Components And Wiring
Check the connector on the infotainment control module (ICM). Check for contact resistance and oxidation and damage.
Check the fuse for the infotainment control module (ICM).
Check the relay for the infotainment system on the central electronic module (CEM).
HINT: A diagnostic trouble code (DTC) is stored in the central electronic module (CEM) if there is a fault in the deployment of the fuse for the infotainment system.
Check the power supply cable between the fuse for the infotainment system and relay terminal #3 and between relay terminal #1 and infotainment control module (ICM) terminal #1 (#A1). Check for an open-circuit. Check for a short-circuit to ground.
Check the ground lead between infotainment control module (ICM) terminal #10 (#A10) and the ground terminal. Check for an open-circuit. Check for a short-circuit to supply voltage. Also check the ground terminal for contact resistance and oxidation.
Remedy as necessary.
