Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Operation-Memory Seat System
The Memory Heated Seat/Mirror Module receives hard wired inputs from the memory set/position switch and the potentiometers, mounted on each of the driver power seat track motors and the driver side view mirror motor. The programmed software in the module allows it to know where the seat/mirror is located in its designed travel by a resistance reading generated from the seat track or mirror mounted potentiometer. This way, when the memory switch is depressed the module will power the seat track or mirror motors until the correct preset location is achieved. The module will prevent the seat memory recall function from being initiated if the driver side seat belt is buckled, if the transmission gear selector lever is not in the Park or Neutral positions, or if the vehicle is moving. These inputs are monitored over the PCI data bus circuit by the BCM.
See the owner's manual for more information on the features, use and operation of the memory seat system. Refer to Electronic Vehicle Information Center in Overhead Console Systems for information on the EVIC.
