Edge AWD V6-3.5L (2009)
Principles of Operation
The Driver Seat Module (DSM) communicates on the Medium Speed Controller Area Network (MS-CAN). The vehicle is not equipped with a DSM if
the vehicle does not have a driver memory seat. If the vehicle is equipped with a DSM, it uses the MS-CAN communication network to permit
inter-module and scan tool communications. The vehicle may have both memory driver seat and memory exterior mirrors, or only memory driver seat, or
neither memory driver seat or memory exterior mirrors.
The DSM controls the memory driver seat and the memory exterior mirrors. The memory feature allows the driver to program personalized seat/mirror
positions. Once the driver stores a memory position, the setting can be recalled by pressing the corresponding memory switch or by using a programmed
Remote Keyless Entry (RKE) Integrated Keyhead Transmitter (IKT). Refer to Seats.
