Seat Belt Switch: Description

The Seat Belt Switch is 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 left seat belt buckle. The left seat belt buckle is located on a stamped steel stanchion within a molded plastic scabbard and secured with a screw to the left side of the transmission tunnel. The seat belt switch is connected to the vehicle electrical system through a two-lead pigtail wire and connector on the left seat belt buckle, which is connected to a wire harness connector in the body 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 left seat belt buckle must be replaced.
