Chime Inoperative With Seat Belt Unfastened
- Turn ignition off. Disconnect seat belt switch harness connector. Turn all lights off. Close all doors. Ensure all courtesy lights are off. Measure resistance between ground and Black wire terminal at seat belt switch harness connector. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Black wire between seat belt switch and ground.
- Turn ignition on. Measure voltage at Light Green/Red wire terminal at seat belt switch harness connector. If voltage is greater than 5.3 volts, go to next step. If voltage is less than 5.3 volts, go to step 4
.
- Check Light Green/Red wire between Body Control Module (BCM) and seat belt switch for short to voltage. If problem exists, repair wiring as necessary. If problem does not exist, replace BCM.
- Turn ignition off. Connect seat belt switch harness connector. Connect scan tool to Data Link Connector (DLC). Ensure seat belt is not fastened. Turn ignition on. Using scan tool, monitor seat belt switch status. If CLOSED is not displayed, go to next step. If CLOSED is displayed, replace Body Control Module (BCM).
- Turn ignition off. Disconnect seat belt switch harness connector. Using a fused jumper wire, ground Light Green/Red wire terminal at seat belt switch harness connector. Turn ignition on. Using scan tool, monitor seat belt switch status. If CLOSED is not displayed, go to next step. If CLOSED is displayed, replace seat belt switch.
- Turn ignition off. Disconnect BCM harness connector C4. Measure resistance in Light Green/Red wire between seat belt switch harness connector and terminal No. 15 at BCM harness connector C4. See Fig 1
. If resistance is 5 ohms or less, replace BCM. If resistance is greater than 5 ohms, repair open in Light Green/Red wire between seat belt switch and BCM.
