Solution

1. Preparation

Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal and wait at least 3 minutes to allow the airbag system to discharge.

2. Replace Blown Fuses

Locate the airbag system fuses in both the under-hood and interior fuse boxes.
Remove the blown fuse using a fuse puller or needle-nose pliers.
Replace it with a new fuse of the same amperage rating.

3. Repair/Replace Airbag Module

If the airbag module is found to be faulty, it must be replaced:
- Remove the dashboard cover or components obstructing access to the airbag module.
- Disconnect the electrical connectors from the module.
- Remove the module mounting bolts using a socket set.
- Install the new airbag module by reversing the removal steps, ensuring all connectors are securely attached.

4. Reconnect Battery

Reconnect the negative battery terminal and ensure it is secured tightly.
Turn the ignition to the "ON" position without starting the engine and check for the airbag light.
