Normal Operation and Fault Conditions 

The DDM and PDM each have a hot at all times voltage supply. The modules monitor this voltage and also receive a battery voltage message from the BCM.

If the voltage to the DDM or PDM drops low enough, all door module functions are inoperative.

DDM/ PDM DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
U3003:62 Battery Voltage: Signal Compare Failure Sets when the DDM or PDM detects the voltage amount from the supply circuit is significantly lower than what is reported from the BCM.
