For circuit descriptions and diagrams, refer to 8W-40 - Instrument Cluster or 8W-44 - Interior Lighting in Group 8W - Wiring Diagrams.

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO GROUP 8M - PASSIVE RESTRAINT SYSTEMS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG 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 section of this group for diagnosis of the chime request circuit. If not OK, repair the open circuit as required.
