Seat Belt Buckle Switch: Description and Operation
SYSTEM DESCRIPTION
The driver seat belt switch is integral to the driver seat belt retractor assembly. The driver seat belt switch is normally closed, providing a ground
signal to the instrument cluster when the ignition switch is in the On or Start positions.
The seat belt switch monitors the amount of seat belt webbing wound onto the seat belt retractor spool. When the seat belt tip-half webbing is
pulled out of the retractor far enough to engage the seat belt buckle-half, the switch opens the seat belt switch sense circuit.
The driver seat belt switch cannot be repaired and, if faulty or damaged, the entire driver seat belt and retractor unit must be replaced.
