Driver Seat Module (DSM)
Principles of Operation
The Driver Seat Module (DSM) is on the Medium Speed Controller Area Network (MS-CAN) communication network. To support several vehicle
subsystems, the module permits intermodule and scan tool communications.
The DSM controls the memory driver seat and the passenger memory power exterior mirror. This passenger memory power exterior mirror feature
allows the driver to program personalized mirror positions. Once the driver stores a memory position, the driver can recall the setting by pressing the
corresponding memory switch or by using a programmed Remote Keyless Entry (RKE) transmitter. Refer to Seats.
