Solution

1. Preparation

Gather tools required, including a multimeter, OBD-II scanner, and basic hand tools.
Disconnect the vehicle battery to prevent accidental airbag deployment.

2. Inspect and Repair Wiring

Visual Inspection
- Inspect the airbag wiring harness thoroughly for any wear or damage.
- Repair or replace any damaged wiring or connectors found during inspection.
Resistance Testing
- Connect the multimeter leads to the airbag connector terminals.
- Compare the measured resistance with the manufacturer's specifications (usually around 2-3 ohms).
- If out of spec, replace the driver's airbag.

3. Replace Airbag Module (if necessary)

Remove the Airbag Module
- Unscrew and disconnect the driver's airbag module from its mounting location.
Install New Airbag Module
- Connect the new airbag module ensuring all connectors are secure.
- Reinstall the module in its original location, tightening screws to manufacturer's torque specifications (typically around 8-10 Nm).

4. Reconnect Battery and Test

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any existing fault codes.
Start the vehicle and monitor for the airbag warning light to confirm that the issue has been resolved.
