Pinpoint Test A: The Power Seat is Inoperative - Driver, With Manual Recliner

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

Normal Operation

Battery voltage is supplied to the driver seat control switch on circuit CBX05 (VT/RD) and ground is supplied on circuit GD904 (BK/BU). When pressed, the seat control switch supplies that voltage and ground to a seat track motor to move the seat to the desired position. 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). 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:
- Fuse
- Wiring, terminals or connectors
- Seat control switch
