Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery and ensure it is safe to work on the airbag system.
Allow the vehicle to sit for at least 10 minutes to ensure any residual power is discharged.

2. Inspect and Repair Wiring

Remove the driver’s side lower dash panel to access the airbag module.
Inspect all wiring harnesses connected to the airbag module for fraying, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors found during the inspection.
Re-secure any loose connections to ensure a proper fit.

3. Replace Faulty Components

If error codes indicate a specific faulty component (e.g., seatbelt buckle or airbag module), remove the affected part:
- Airbag Module: Unplug the connector and remove the module using a socket set.
- Seatbelt Buckle: Unfasten the seatbelt assembly and replace the buckle as needed.
Install the new component in reverse order of removal, ensuring all connectors are securely attached.
