Memory Mirrors (A45) Parallel Parking Mode

If the vehicle is equipped with memory mirrors, it is equipped with the parallel parking mode feature. For this feature, the driver door module communicates with the Powertrain Control Module (PCM) over the class 2 data link. When the gear selector is shifted to reverse, the PCM transmits this status via a class 2 message to the driver door module. The driver door module sends this message on to the passenger door module over the power door serial data circuit.

The Passenger Front Door Module (PDM) then supplies battery positive voltage and ground to the vertical motor of the RH outside rear view mirror to tilt the mirror down 7 degrees. This allows the driver to see the curb while parallel parking.
