Memory Mirrors - Parallel Parking Mode
The Passenger Front 
Door Module (PFDM) communicates with the Powertrain Control Module 
(PCM) over the Serial Data Class 2 data line. When the gear selector is shifted to reverse the PCM will transmit the class 2 message to the PFDM. The PFDM will tilt the RH outside power mirror down 
7 degrees. This allows the driver to see the curb while parallel parking.
