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.
Memory Seat/Mirror Module: Operation
When memory system operation is requested (depressing of the memory switch), a resistor multiplexed signal is sent from the memory switch to the body control module (BCM). The body control module will then send the appropriate signals out to the memory/mirror seat module, the memory/mirror seat module then applies the voltage supply to the power seat track or side-view mirror if the proper requirements are met. The vehicle speed must equal zero and the transmission must be in park or neutral in order for the memory system to function.
