Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, trim removal tool.
Disconnect the vehicle battery and wait for at least 10 minutes to ensure that all capacitors in the airbag system are discharged.
Ensure you are working in a well-ventilated area.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve all logged airbag-related trouble codes.
Note the codes for reference before clearing them.
Clear the trouble codes using the scanner and disconnect the OBD-II tool.

3. Inspect Wiring and Connectors

Remove any necessary trim panels using the trim removal tool to access airbag wiring.
Visually inspect all connectors related to the airbag system for corrosion or loose connections.
Use a multimeter to check for continuity in the wiring harness between the airbag module and the connectors.

4. Replace Faulty Components

If any damaged connectors or wiring are found, replace them with new OEM parts.
If diagnostic codes indicate a faulty airbag module, replace it with a new one, ensuring it’s compatible with the vehicle.

5. Reassemble and Test

Reconnect all wiring and connectors securely, ensuring no wires are pinched or exposed.
Reinstall any trim panels removed during the inspection.
Reconnect the vehicle battery and turn on the ignition to check if the airbag light remains off.
If the light is still illuminated, further diagnosis may be required.
