Normal Operation and Fault Conditions

WARNING: This page is about a different car, the 2013 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

Based on messages received from the BCM  , the DDM  commands the Driver Rear Door Module (DRDM) to supply voltage and ground to illuminate the LH  rear window control switch via a LIN  circuit.
