Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, safety glasses, and gloves.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental deployment of the airbags.

2. Inspect and Repair Wiring and Connectors

Sub-steps:
1. Remove the driver's side lower trim panel to access the airbag wiring harness.
2. Visually inspect all connectors for corrosion or damage; disconnect and reconnect each to ensure a proper connection.
3. Use a multimeter to check for continuity in the wiring leading to the airbag modules.
4. Repair any damaged wires or replace connectors as necessary.

3. Check and Replace Airbag Fuse

Sub-steps:
1. Locate the fuse box and identify the airbag fuse using the diagram on the cover.
2. Remove the fuse using a fuse puller or pliers.
3. Inspect the fuse for continuity with a multimeter; replace it if blown.
4. Install a new fuse of the same amperage rating.

4. Test Airbag System Functionality

Sub-steps:
1. Reconnect the negative battery terminal.
2. Turn the ignition key to the "ON" position without starting the engine; the airbag light should illuminate briefly and then turn off.
3. If the light remains on, repeat the diagnostic steps to ensure all issues are resolved.
