Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.
Disconnect the negative battery cable and wait at least 10 minutes to allow the airbag system to discharge.
Ensure you are working in a clean, well-lit area.

2. Retrieve Diagnostic Codes

Use the OBD-II scanner to connect to the vehicle's diagnostic port.
Record any airbag-related error codes displayed, as they will guide the next steps in repairs.
Clear the codes and check if they reappear after starting the vehicle.

3. Inspect Wiring and Connectors

Remove the seat cushion or cover to access the wiring harnesses under the seat.
Inspect all wiring and connectors for signs of wear, corrosion, or disconnection.
Secure or replace any damaged connectors and ensure all connections are tight.

4. Test Seat Occupancy Sensors

Use a multimeter to check the resistance of the seat occupancy sensors.
Follow the manufacturer's specifications for resistance values; replace any sensors that are out of range.
Reconnect any disconnected wiring and secure the assembly.

5. Replace Airbag Control Module (if necessary)

If diagnostic codes indicate a faulty airbag control module, remove the old module by unscrewing it from its mount.
Disconnect the electrical connectors and replace it with a new module, ensuring all connections are secure.
Torque the mounting screws to the manufacturer's specifications.

6. Reconnect the Battery

Reconnect the negative battery cable securely.
Start the vehicle and check if the airbag light remains off.
