Switch, Seat Belt: Description
The driver and passenger side front seat belt switches for this vehicle are actually Hall Effect-type sensors. These sensors consist of a fixed-position, Hall Effect Integrated Circuit (IC) chip and a small permanent magnet that is integral to each front seat belt buckle (1). The front seat belt buckles are located on a molded plastic scabbard and secured by a screw (2) to the inboard side of each front seat cushion frame so that the buckles travel with the seat.
The front seat belt switches are connected to the vehicle electrical system through a two-wire pigtail lead and connector (3) on the front seat belt buckle-half, 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 wires connect to the IC terminals.
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.
