Driver Door Module (DDM)

The Driver Door Module (DDM) is wired to the the drivers door power door lock motor. Upon receipt of a lock or unlock request from the RIM over the Serial Data Class 2 line, the DDM applies voltage directly to the driver door lock motor to operate the lock or unlock function. Voltage of the correct polarity is applied to run the motor in one direction for the lock request, or, reversed to run the motor in the opposite direction for the unlock request. Battery voltage to the DDM is supplied through circuits wired to the circuit breakers located in the Rear Fuse (Bussed) Block.
