Principles of Operation

PRINCIPLES OF OPERATION

The DSM is on the controller area network (CAN) communication network to support the memory driver seat. If a memory driver seat is not equipped on the vehicle, the DSM does not have CAN communication. If the DSM is on the CAN communication network, it permits intermodule and scan tool communications. The vehicle may have both memory driver seat and memory exterior mirrors, or only 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.
