Switch, Seat Belt: Description

The driver side seat belt switch for this vehicle is actually a Hall Effect-type sensor. This sensor consists of a fixed-position, Hall Effect Integrated Circuit (IC) chip and a small permanent magnet that is integral to the driver side seat belt buckle. The seat belt buckle is located on a molded plastic scabbard and secured by a screw to the inboard side of the upper inboard adjuster track so that the buckle travels with the seat.

The seat belt switch is connected to the vehicle electrical system through a pigtail wire and connector on the seat belt buckle and tensioner unit, which is connected to a wire harness connector and take out of the seat wire harness. A one kilohm diagnostic resistor is connected in parallel with the IC where the two pigtail wire leads connect to the IC pins.

The seat belt switch cannot be adjusted or repaired. If ineffective or damaged, the entire driver side seat belt buckle and tensioner unit must be replaced. Refer to BUCKLE, SEAT BELT, REMOVAL .
