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

Refer to Wiring Diagrams Set 120, Power Seats for schematic and connector information.

Normal Operation

Battery voltage is supplied to the passenger seat control switch on circuit CBX05 (VT/RD) and ground is supplied on circuit GD903 (BK/WH). When pressed, the seat control switch supplies that voltage and ground to a seat track motor to move the seat in the desired direction. There are 3 seat track motors that combine to move the seat cushion horizontally (forward/rearward) and vertically (front up/down and rear up/down). There is an additional motor in the seat recliner mechanism to move the seat backrest forward and rearward. If a new motor on the seat track needs to be installed, it is necessary to install an entire seat track assembly.

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