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 Set Switch: Operation
When any of the memory switches are depressed, a resistance signal is sent to the Driver Door Module via hard wired connections. The memory set switch LED will flash red when pressed until a position button is pressed or the system times out. The driver door module then sends the request to the Memory Heated Seat Adjustable Pedal Module (MHSAPM) via the PCI data bus circuit. The MHSAPM is responsible for controlling the 12v battery feed and ground path to the power seat track or adjustable pedal motor(s) to control the seat or pedal assembly accordingly.
