Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle’s battery and wait for at least 10 minutes to avoid accidental airbag deployment.
Ensure you have a safe working area.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any DTCs related to the airbag system.
Clear the codes and see if the airbag light returns after starting the vehicle.

3. Inspect Wiring and Connectors

Remove the front seats if necessary to access wiring.
Check for damaged wires or loose connections in the airbag system harness.
Repair any damaged wires and ensure all connectors are securely attached.

4. Check Seatbelt Pretensioners

Locate the seatbelt pretensioners and inspect their wiring and connectors.
If damaged, replace the pretensioners with new units.
Ensure that the pretensioner is properly bolted down to the vehicle frame.

5. Replace Airbag Control Module (if necessary)

If the airbag control module is faulty, remove it by unbolting it and disconnecting the wiring harness.
Install the new airbag control module and reconnect the connectors.
Ensure all components are secured and properly connected.
