Description & Operation: Notes

WARNING: Vehicles are equipped with air bag supplemental restraint system. Before attempting ANY repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in AIR BAG RESTRAINT SYSTEMS article.

The seat assembly is secured to the floor pan, by nuts installed on floor pan anchor plate studs. See illustration Fig 1 . The six-way seat adjusters are powered by three 12-volt reversible, permanent magnet motors with built-in circuit breakers. The motors are energized by a toggle type control switch installed in the driver's door armrest or the seat bolster.

The system is grounded by a wire secured to the seat frame and under one of the seat adjuster-to-floor pan attaching nuts. The three motors respectively direct drive the front and rear vertical gearnuts and a horizontal actuator. When the adjusters reach the limit of travel, torque is absorbed through the rubber mounted grommets located between the motor and the support.

An overload relay is provided in the circuit should excessive stall torque be applied to the motor. Power operated reclining seatback is equipped with a small Permanent Magnet (PM) type motor located under the seat cushion frame. The motor drives a reclining actuator on the outboard side of the seat cushion frame by means of a drive cable.
