Memory Mirrors - Parallel Parking Mode

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 will transmit a class 2 message to the driver door module. The driver door module will send this message on to the passenger door module over the Simple Bus Interface (SBI). the passenger door module will tilt the RH outside rear view mirror down 7 degrees. This allows the driver to see the curb while parallel parking.
