Solution

1. Preparation

Gather tools and parts needed.
Disconnect the vehicle battery to prevent any electrical shorts while working.
Ensure the vehicle is in a safe, well-lit area.

2. Inspect and Clean Seatbelt Buckle Switches

Locate the seatbelt buckle switch by removing the cover from the seatbelt assembly.
Disconnect the electrical connector from the buckle switch.
Use a contact cleaner to remove any debris and corrosion from the switch.
Reconnect the switch and test for proper function.

3. Check Fuses

Locate the fuse box under the dashboard and/or in the engine compartment.
Identify and inspect the fuse corresponding to the seatbelt warning system (refer to the owner's manual for location).
Replace any blown fuses with the appropriate amperage specified in the manual.

4. Test the Seatbelt Warning Light Circuit

Reconnect the battery and turn the ignition to the ON position (without starting the engine).
Use a multimeter to measure voltage at the seatbelt warning light circuit connector.
- If voltage is present, check the bulb for faults.
- If no voltage is present, trace the circuit back to the control module.

5. Replace the Seatbelt Control Module (if necessary)

If the control module is determined faulty, remove it by unscrewing the mounting screws.
Disconnect the wiring harness from the module.
Install the new control module by reversing the removal steps and reconnecting the wiring.
