Passenger Seat

OPERATION

The passenger seat switch has up to three momentary switch buttons. The heated seat switch portion of the switch is back-lit with Light-Emitting Diodes (LEDs) for easy visibility. When any of the switch buttons are depressed, a resistance signal is sent to the Passenger Door Module (PDM) via hard wired connections. The PDM then sends the request to the Memory Heated Seat Adjustable Pedal Module (MHSAPM) via the Programmable Communications Interface (PCI) data bus circuit. The MHSAPM is responsible for controlling the 12volt battery source and ground path to the seat heating elements or power seat track mounted motors to control the seat accordingly.

Any seat axis or seat heat inputs can be activated at the same time (except contradictory inputs). The PDM has two outputs to the seat switch to indicate heat level (HI/LO). The power seat system is operational in any ignition switch position. The heated seat system only operates with the ignition on. The individual components of the passenger seat switch are not available for service and if found to be inoperative or damaged, the complete assembly must be replaced.
