OPERATION

When the recliner switch control knob is actuated, a resistance signal is sent to the appropriate Door Module via hard wired connections. The door module 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 recliner adjuster motor. The adjuster motor operates to move the recliner mechanism through its drive unit in the selected direction until the switch is released, or until the travel limit of the adjuster is reached.

The driver side power seat recliner motor used on models equipped with the memory system also has a position potentiometer integral to the motor assembly, which electronically monitors the motor position.
