Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Wait at least 10 minutes after disconnecting the battery to allow the airbag system to disarm.

2. Scanning and Identifying Faults

Use an OBD-II scanner to read stored error codes.
Document any error codes related to the airbag system.
Clear the error codes and see if they return after a short test drive; this can help identify persistent issues.

3. Inspecting Components

Airbag Module and Connectors:
- Remove the driver's side lower dash panel.
- Locate the airbag control module and inspect its connectors for corrosion or loose connections.
- If damaged, replace the module as necessary.
Clockspring Inspection:
- Remove the steering wheel using a socket set (be cautious of airbag deployment).
- Inspect the clockspring for any visible damage; replace if necessary.
Seatbelt Pretensioners:
- Check the connectors and wires leading to the seatbelt pretensioners.
- Ensure they are securely connected and not frayed.

4. Reassembly and Reconnection

Reconnect any disconnected components and ensure all are secure.
Reattach the steering wheel and lower dash panel.
Reconnect the negative battery terminal.

5. Final Checks

Perform a final scan with the OBD-II scanner to ensure all error codes have been cleared.
Test the airbag system by turning on the ignition and checking if the airbag light goes off.
