Principles of Operation: Notes

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The Driver Door Module (DDM) allows the driver to program a personalized seat position that can be recalled using the memory set switch or a Remote Keyless Entry (RKE) transmitter (part of the Integrated Keyhead Transmitter (IKT) [Passive Anti-Theft System (PATS) only] key or part of the Intelligent Access (IA) [PATS with push button start] key). In addition to the position of the driver exterior mirror, the DDM also controls the position of the passenger exterior mirror and the adjustable pedals. The DDM is hardwired to the power mirror switch, driver exterior mirror, memory set switch and sends messages over the Medium Speed Controller Area Network (MS-CAN) to the Driver Seat Module (DSM) to adjust the passenger exterior mirror. Refer to HYDRAULIC BRAKE ACTUATION for information on the adjustable pedals. Refer to REAR VIEW MIRRORS for information on the exterior mirrors.
