Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent accidental deployment of the airbags.
Allow the vehicle to sit for at least 10 minutes to ensure the airbag system discharges.

2. Check and Replace Fuses

Locate the fuse box; refer to the owner's manual for the specific location.
Remove the airbag fuse using a fuse puller or needle-nosed pliers.
Inspect the fuse visually; if it is blown, replace it with a new fuse of the same amperage.
Reinstall the fuse and reconnect the negative battery terminal.

3. Inspect and Repair Wiring

Remove the lower dash cover to access the airbag wiring.
Carefully inspect all connectors and wiring leading to the airbag system for frays or disconnections.
Repair any damaged wiring using appropriate electrical tape or heat shrink tubing.
Ensure all connectors are securely plugged in and free from corrosion.

4. Reset Airbag Light

Reconnect the OBD-II scanner to the vehicle.
Clear any DTCs stored in the airbag control module using the scanner.
Turn the ignition on and check if the airbag light turns off.

5. Test the System

Reconnect the negative battery terminal if it was disconnected.
Start the vehicle and observe the dashboard for the airbag light.
Conduct a test drive to ensure the light does not re-illuminate.
