Test A: The Power Seat Is Inoperative

PINPOINT TEST A: THE POWER SEAT IS INOPERATIVE

Normal Operation
The seat control switch is powered by battery voltage to circuit 517 (BK/WH) and is supplied ground on circuit 57 (BK). The seat control switch applies battery power and ground directly to one of 3 bi-directional seat track motors, respectively, to move the seat. Toggling the seat control switch to the opposite position reverses the voltage polarity applied to the respective seat motor and moves the seat in the opposite direction.

This pinpoint test is intended to diagnose the following:
- Faulty circuit breaker
- Faulty circuit
- Faulty seat control switch
- Faulty seat track
