Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's negative battery terminal to prevent accidental airbag deployment.
Allow the vehicle to sit for at least 10 minutes to ensure capacitors in the airbag system are discharged.

2. Inspect and Repair Wiring

Remove the driver's side and passenger side lower dash panels using a socket set and trim removal tools.
Inspect wiring harnesses for damage or disconnections, particularly near the airbag connectors.
Repair any damaged wires by splicing in new wire and securing with electrical tape or heat shrink tubing.

3. Replace Faulty Components

If diagnostics indicate a faulty airbag module:
- Remove the airbag control module from its mounting location.
- Disconnect the wiring harness and install the new module.
- Secure it in place and reconnect the battery.
If the issue is with the occupant classification system:
- Remove the passenger seat and check for the sensor located underneath.
- Replace the sensor if it is damaged.

4. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag codes.
Verify that the airbag light goes off after clearing the codes.
