- Unscrew and detach the steering wheel cover.
- Disconnect the airbag connector carefully.
Remove any necessary panels to access the airbag control module.

3. Inspect and Repair

Wiring Inspection:
- Check for damaged or frayed wires in the airbag system.
- Repair or replace any damaged wiring found during inspection.
Connector Cleaning:
- Clean any corrosion or debris from the airbag connectors using electrical contact cleaner.

4. Replace Faulty Components

If the airbag control module shows faults, replace it with a new one.
If seatbelt pretensioners are defective, replace them with OEM parts.

5. Reassemble and Reconnect

Reattach the airbag module and any removed panels or covers.
Reconnect the negative battery terminal.
Clear any diagnostic trouble codes using the OBD-II scanner.
