Seat Belt Switch: Description
The seat belt switches for this model are actually Hall Effect-type sensors. This sensor consists of a fixed-position, Hall Effect Integrated Circuit (IC) chip and a small permanent magnet that are integral to the driver side and passenger side front seat belt buckle (1). The front seat belt buckles are located on stamped steel stanchions and secured with a screw (3) to the inboard side of each front seat cushion frame between the seat and the floor panel transmission tunnel.
The seat belt switches are connected to the vehicle electrical system through a two-lead pigtail wire (4) and connector on the front seat belt buckle-half, which is connected to a wire harness connector and take out of the seat wire harness beneath the rear edge of each front seat cushion frame. A radio noise suppression capacitor is connected in parallel with the IC where the two pigtail wire leads connect to the IC pins.
The seat belt switches cannot be adjusted or repaired and, if ineffective or damaged, the entire front seat belt buckle-half unit must be replaced.
