Remove the front seats if necessary to access the seatbelt connectors.
Check the connectors for any corrosion or loose connections.
Clean any corrosion with an electrical contact cleaner and reassemble.

4. Repair or Replace Faulty Components

If trouble codes indicate a specific fault (e.g., faulty airbag module, seatbelt tensioner), replace the affected component.
Ensure any replacement parts are OEM or high-quality aftermarket components.
