Solution

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
