Right Rear Door Module (RRDM) And Left Rear Door Module (LRDM)

The rear door modules (RRDM) and (LRDM) control their respective rear door lock actuators. The RIM commands them to lock or unlock the doors via a Serial Data Class 2 line message. Voltage of the correct polarity is applied to run the associated motor in one direction for the lock request, or, reversed to run the associated motor in the opposite direction for the unlock request. Battery voltage is supplied to both rear door modules through circuits wired to the circuit breakers located in the Rear Fuse (Bussed) Block.
