Test E: The Power Seat Does Not Move Horizontally/Vertically
PINPOINT TEST E: THE POWER SEAT DOES NOT MOVE HORIZONTALLY/VERTICALLYNormal Operation
When pressed in one of 6 available directions, the seat control switch supplies battery voltage and ground to one of three seat track assembly motors through horizontal motor circuits CPS23 (GN/VT) and CPS28 (GN), front height motor circuits CPS24 (GY) and CPS25 (WH/VT) or rear height motor circuits CPS26 (YE/BU) and CPS27 (BU/BN). The seat control switch is normally closed to ground on all 6 of the seat motor circuits, so if one circuit becomes closed to power, the circuit on the opposite side of the same motor is still closed to ground. The seat motor will then operate, moving the seat track in the selected direction. Moving the seat control switch in the opposite direction reverses polarity to the seat motor, which causes the seat motor to move the seat track in the opposite direction.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Seat control switch
- Seat track
