Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery and wait at least 10 minutes to ensure the airbag system is deactivated.
Tools Required: OBD-II scanner, socket set, multimeter, torque wrench.

2. Inspect Airbag Wiring

Remove the steering wheel cover to access the airbag connectors.
- Use a socket set to remove screws securing the cover.
- Carefully detach the cover without damaging clips.
Check the airbag connectors for corrosion or loose fittings.
- If damaged, replace connectors or repair wiring as necessary.

3. Test Airbag Control Module

Reconnect the battery and use the OBD-II scanner to clear any fault codes.
Recheck for codes to see if any persist.
If codes reappear, remove the airbag control module for testing.
- Unplug the module and inspect the connector pins for corrosion.
- Use a multimeter to test the module for continuity and proper voltage.

4. Replace Faulty Components

If the airbag control module is faulty, replace it with a new unit.
- Ensure the new module is compatible with the vehicle.
- Torque the module to manufacturer specifications (usually around 7-10 Nm).
If any airbag modules are faulty, replace them following manufacturer guidelines.

5. Reassemble and Test

Reassemble all components removed during the diagnostic and repair process.
Reconnect the battery and start the vehicle.
Use the OBD-II scanner to verify that no error codes are present and that the airbag light is no longer illuminated.
