Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a flat-head screwdriver.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Disconnect the negative battery terminal to prevent accidental deployment of airbags.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition key to the "ON" position without starting the engine.
Read the error codes and note any specific codes related to the airbag system.
Research the codes to identify the exact issue (e.g., whether it's a sensor issue, wiring fault, etc.).

3. Inspect Connections

Locate the seatbelt and airbag connectors under the seats and in the steering wheel area.
Carefully disconnect each connector and inspect for corrosion, dirt, or damage.
Clean any dirty contacts with electrical contact cleaner and reconnect securely.

4. Check Fuses

Locate the fuse box (refer to the owner's manual for the exact location).
Identify the fuse related to the airbag system (usually labeled).
Use a multimeter to check for continuity in the fuse; replace if damaged.

5. Reset the Airbag Light

Once repairs are made, reconnect the negative battery terminal.
Use the OBD-II scanner to clear the airbag error codes from the system.
Start the vehicle and check if the airbag light is still illuminated.
