Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's negative battery terminal to ensure safety.
Wait at least 10 minutes to allow the airbag system to discharge.

2. Inspect Wiring and Connections

Remove the driver's side lower dash panel to access the airbag system wiring.
Visually inspect the wiring harness for fraying, corrosion, or loose connections.
Ensure all connectors are securely attached and free of dirt or moisture.

3. Test the Airbag Module

Locate the airbag module, typically beneath the center console or under the seat.
Disconnect the module connector and measure the resistance across the terminals with a multimeter.
- Expected resistance: 2-3 ohms (consult the service manual for exact specifications).
If resistance is outside this range, replace the airbag module.

4. Replace or Repair Components

If damaged wiring is found, repair or replace the affected wiring harness.
If the airbag module fails the resistance test, replace it with a new module.
Ensure all connectors are clean and secure before reassembly.

5. Reconnect Components

Reconnect the airbag module and all connectors.
Reinstall the driver's side lower dash panel.
Reconnect the negative battery terminal.
