Passenger

OPERATION

When a power seat switch control knob is actuated, 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 the 12v battery feed and ground path to the power seat track adjuster motor. The selected adjuster motor operates to move the seat track or recliner through its drive unit in the selected direction until the switch is released, or until the travel limit of the adjuster is reached.
