Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery and wait at least 10 minutes to allow the airbag system to discharge.
Ensure the vehicle is in a safe, well-ventilated area.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve and record any airbag-related error codes.
Document codes for reference during the repair process.

3. Inspect Components

Visually inspect the airbag control module, seatbelt sensors, and connectors for damage or corrosion.
Clean connectors with electrical contact cleaner if corrosion is present.

4. Repair or Replace Faulty Components

If a faulty seatbelt sensor is indicated, replace it:
- Disconnect the electrical connector.
- Remove the retaining screws and take out the sensor.
- Install the new sensor and reconnect the electrical connector.
If the airbag control module is determined to be faulty, replace it:
- Unplug the connectors from the module.
- Remove the mounting bolts and take out the module.
- Install the new module and reconnect the wiring.

5. Clear Error Codes

After repairs, use the OBD-II scanner to clear any error codes.
Reconnect the battery.

6. Final Check

Turn the ignition to the “On” position without starting the engine to check if the airbag light turns off.
If the light remains on, further diagnostics may be necessary.
