Power Seats System



POWER SEATS SYSTEM DESCRIPTION AND OPERATION

POWER SEAT SYSTEM OPERATION
The power seats are controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the SEATSW 40A fuse in the underhood BEC and the Power Seats 20A circuit breaker in the driver seat wiring harness. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.
