Seat Belt Switch: Description
The seat belt switch for this model 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 front seat belt buckle. The driver side front seat belt buckle is located on a molded plastic scabbard and secured along with the seat belt tensioner mechanism by a nut to the inboard side of the driver side front seat cushion frame. The seat belt switch is connected to the vehicle electrical system through a two-lead pigtail wire and connector (1) on the driver side front seat belt buckle-half, which is connected to a wire harness connector and take out of the seat wire harness. 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 switch cannot be adjusted or repaired and, if faulty or damaged, the entire driver side front seat belt buckle-half and tensioner unit must be replaced.
