Memory Power Mirrors

Each outside mirror contains vertical and horizontal bi-directional drive positioning motors and position sensors. The Driver Door Module (DDM) and Passenger Door Module (PDM) provide a 5-volt reference on the signal circuit to each position sensor. The sensors share a common ground circuit. The DDM and PDM monitor the position of the mirror motors by measuring the voltage on each signal circuit. When a memory position is set, the DDM and PDM monitor and store the position of the outside mirrors. The DDM and PDM adjust the mirrors to the appropriate positions when a memory recall message is received from the RKE or is requested from the memory recall switch.
