Power Seat Control Module: Description and Operation

DRIVER SEAT MODULE - MEMORY SEAT

The power driver seat, power outside rear view 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 on the driver seat track.

This system allows automatic positioning of the driver seat to 2 programmable positions.

The memory seat system consists of the following components:
- DSM
- Driver memory seat control switch
- Memory set switch
- Adjustable pedal switch
- Power mirror switch
- Adjustable steering column switch
- Memory seat track assembly (with seat position sensors integral to motors)
- Horizontal motor (part of seat track)
- Front height motor (part of seat track)
- Rear height motor (part of seat track)

- Backrest power recliner motor (with integral position sensor) (part of backrest frame)
- LH memory power mirror
- RH memory power mirror
- Power adjustable memory pedals
- Power adjustable steering column
- Remote keyless entry transmitter

Two personalized seat positions may be programmed into the memory seat system. A memory seat position may be set by first positioning the driver seat using the driver power seat switch and depressing the memory set switch. Memory seat position 1 or 2 must be selected within 5 seconds to set a personalized seat position. If position 1 or 2 is not selected within 5 seconds, the operation is aborted. This operation also aborts if any input is received from the driver power seat switch, the power mirror switch, the adjustable pedal switch, the power adjustable steering column switch or if the memory set switch is depressed again during the 5-second limit. The personalized memory seat positions are recalled using the memory switch positions 1 and 2 or with the remote keyless entry transmitter.

A programmed seat position can only be recalled when the transmission selector is in PARK or NEUTRAL with the ignition switch in the RUN position. A position may be programmed at any time.
