Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wiring diagram.
Ensure the vehicle is in a safe, well-ventilated area with the ignition off.
Disconnect the negative battery terminal and wait at least 10 minutes to allow the airbag system to discharge.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Retrieve and document any airbag-related trouble codes (e.g., B0001, B0090).

3. Inspect Airbag System Components

Remove any necessary trim panels to access the airbag sensors and wiring.
Visually inspect the airbag connectors, wiring, and sensors for any signs of damage or corrosion.
Ensure all connectors are securely fastened and free from debris.

4. Check Seatbelt Buckle

Inspect the seatbelt buckle mechanism for proper operation.
Test the seatbelt buckle connection to the airbag system using a multimeter to ensure it is functioning correctly.

5. Check Airbag Control Module

Locate the airbag control module (typically found near the passenger footwell or under the center console).
Inspect the module for any physical damage and ensure all connections are secure.
If necessary, replace the airbag control module according to manufacturer specifications.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag trouble codes.
Turn on the ignition and check if the airbag light turns off.
