Driver Seat Switch: Operation

The heated seat button is back-lit with Light-Emitting Diodes (LED) for easy visibility. The memory set button blinks red when depressed until one of the position buttons (1 or 2) are pushed. When any of the switches are depressed, a resistance signal is sent to the Driver Door Module via hard wired connections. 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 seat heating elements or power seat track/foot pedal mounted motors to control the seat accordingly.

Any seat/pedal axis or seat heat inputs can be activated at the same time (except contradictory inputs). The driver door module has two outputs to the seat switch to indicate heat level (HI/LO). The power seat system is operational in any ignition switch position. When the memory system is in "set" mode a chime will be generated by the body control module. See the owner's manual in the vehicle glove box for more information on the seat switch functions and the seat adjusting procedures.
