Normal Operation
The memory mirrors are controlled by the driver seat module (DSM), which receives its commands over the communication network from the driver door module (DDM). The DDM is hardwired to the driver seat control switch, which includes the memory switches and memory LED. The driver seat control switch receives voltage from the central junction box (CJB) through circuit 1524 (DB). The memory switches are normally open, momentary contact, push button-style switches that send a voltage signal to the DDM when closed. The DDM interprets the voltage signal and commands the DSM to move the power seats, mirrors and adjustable pedals. The memory set switch 1 is hardwired to the DDM through circuit 267 (BN/LG), memory 2 through circuit 268 (BK/OG), and memory set through circuit 270 (BN/OG). The memory LED is hardwired to the DDM through circuit 272 (WH/OG). When a memory position command is entered the DDM provides a ground path and the memory LED illuminates to confirm proper operation. The DSM monitors the exterior mirror positions through hardwired position sensors and retains memory of the mirror positions as long as power is supplied to the module. When a remote keyless entry (RKE) transmitter or keypad position command is received by the DDM, a signal is sent over the communication network to the DSM, which commands the mirrors to move to 1 of 2 memorized positions. The DSM is hardwired to the position sensors through circuits 954 (DG/WH), 957 (VT/WH), 955 (GY), 958 (GY/RD), 949 (RD/WH), and 951 (DB/WH).
Possible Causes
- circuit 267 (BN/LG) open, short to ground, short to voltage
- circuit 268 (BK/OG) open, short to ground, short to voltage
- circuit 270 (BN/OG) open, short to ground, short to voltage
- circuit 272 (WH/OG) open, short to ground, short to voltage
- driver seat control switch
- DDM
