Power Seat Control Module: Description and Operation

DRIVER SEAT MODULE - MEMORY SEAT

The driver power bucket seat, power exterior mirrors, power adjustable pedals and adjustable steering column are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option. The DSM is located under the driver seat. To install a new DSM, refer to Body Control Systems (Multifunction Electronic Control Module). Programmable module installation (PMI) must be carried out when installing a new DSM. Refer to Information Bus (Module Communications Network).

This system allows automatic positioning of the driver power bucket seat, power exterior mirrors, power adjustable pedals and power tilt steering column to 2 programmable positions. The personalized memory seat positions are recalled using memory switch buttons 1 and 2 or with the RKE transmitter. Memory positions can be stored at any time. A memory recall can be initiated only if the vehicle is in PARK or NEUTRAL and the ignition switch is not in START. A memory recall in progress will not be affected by moving the ignition switch to START or by moving the selector lever out of PARK or NEUTRAL. For information on programming memory positions or recalling stored memory position, refer to Memory Position Programming. Programming and Relearning
