Test F: The Power Seat Does Not Move Horizontally/Vertically/Recline - Passenger

PINPOINT TEST F: THE POWER SEAT DOES NOT MOVE HORIZONTALLY/VERTICALLY/RECLINE - PASSENGER

Normal Operation
The passenger seat control switch is powered by battery voltage on circuit 490 (RD) and is supplied ground on circuit 57 (BK). When pressed, the seat control switch supplies that voltage and ground to the appropriate passenger power seat track or recliner motor circuits to move the seat or backrest. When pressed in the opposite direction, the seat control switch reverses the polarity to that same power seat track or recliner motor, which moves the seat or backrest in the opposite direction. There are 3 power seat track motors that combine to move the seat horizontally (forward/reverse) and vertically (front up/down and rear up/down).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Seat control switch
- Power recliner assembly
- Seat track motor
