Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery and wait at least 10 minutes to ensure the system discharges.
Tools Required: OBD-II scanner, socket set, multimeter, and a flat-head screwdriver.

2. Inspect Wiring and Connectors

Remove the driver's side lower dash panel to access the airbag system wiring.
Inspect the airbag connectors for loose connections or damaged pins.
- If damage is found, repair or replace the connectors as necessary.
Reconnect all wiring securely.

3. Check Fuses

Locate the fuse box and identify the airbag fuse.
Use a multimeter to test the fuse for continuity.
- If the fuse is blown, replace it with a fuse of the same amperage rating.

4. Test Airbag Modules

Use the OBD-II scanner to read the stored airbag codes.
Clear the codes and perform a test drive to check if the airbag light returns.
- If the light comes back on, further diagnostic testing may be required.

5. Reconnect Battery

Once all checks and repairs are completed, reconnect the battery.
Ensure all tools are removed from the vehicle before starting.
