Seat Belt Buckle Switch: Testing and Inspection
WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS AND SEAT BELTS/AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
1. Disconnect and isolate the battery negative cable. Unplug the wire harness connector from the driver seat belt retractor. Check for continuity
between the circuit cavity in the body half of the driver seat belt switch wire harness connector and a good ground. There should be continuity. If
OK, go to Step 2. If not OK, repair the open circuit as required.
2. Check for continuity between the two cavities in the seat belt half of the driver seat belt switch wire harness connector. There should be no
continuity with the seat belt webbing retracted, and continuity with the seat belt webbing pulled out of the retractor far enough to engage the seat
belt buckle. If OK, go to Step 3. If not OK, replace the faulty driver side seat belt and retractor assembly.
3. Remove the instrument cluster from the instrument panel. Check for continuity between the seat belt switch sense circuit cavities of the instrument
cluster wire harness connector (connector B) and the body half of the driver seat belt switch wire harness connector. There should be continuity. If
OK, see Instrument Cluster in the Diagnosis and Testing for diagnosis of the chime request circuit. If not OK, repair the open circuit as required.
