Check the power supply cable between central electronic module (CEM) C1/21 and infotainment control module (ICM) terminal #1 (#A1). Check for an open-circuit. Check for a short-circuit to ground.
HINT: A diagnostic trouble code (DTC) is stored in the central electronic module (CEM) if there is a fault in the control of the infotainment relay.
Check the ground lead between infotainment control module (ICM) terminal #3 (#A3) and the ground terminal. Check for an open-circuit. Check for a short-circuit to supply voltage. Also check the ground terminal. Check for contact resistance and oxidation.
