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.
Heated Seat System Operation
The Memory Heated Seat/Mirror Module receives hard wired inputs from the heated seat switches and the heated seat sensors located, on each of the front seats. The programmed software in the MHSMM allows it to know the temperature of the seat by a resistance reading generated from the seat cushion element mounted thermistor (Heated Seat Temperature Sensor). When a heated seat switch is depressed the module will power the appropriate heating element until the correct preset temperature is achieved. Refer to DRIVER HEATED SEAT SWITCH for additional information.
