Normal Operation
A 3-lead sensor is attached to each motor on the memory seat track and recliner assembly. The sensor circuits are connected to the driver seat module (DSM) which supplies the sensor power and receives the sensor signals. The DSM receives data from the memory seat position sensors to monitor the positions of the seat track and recliner motors. This motor position data is stored when the DSM receives a SET switch input signal and recalled when it receives a RECALL switch input signal. The driver door module (DDM) is directly connected to the memory SET/RECALL switch and transmits the switch signal data to the DSM using the SCP communication bus. The DSM also receives memory recall signals from the remote transmitter over the SCP communication bus transmitted by the lighting control module (LCM).

Possible Causes
A memory seat that does not move horizontally, vertically or does not recline can be caused by:
- wiring, terminals or connectors.
- a faulty memory set switch.
- a faulty power seat track motor position sensor.
- a faulty DSM.
