Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Allow the vehicle to sit for at least 10 minutes to ensure the airbag system is disarmed.

2. Retrieve and Analyze Error Codes

Use an OBD-II scanner to access the airbag control module.
Note any error codes and refer to the service manual for interpretation.
Clear the codes and see if the airbag light returns after a test drive.

3. Inspect Wiring and Connectors

Remove the seat and inspect the connectors under the seats for loose or damaged wires.
Ensure that all connectors are securely attached, particularly the ones leading to the airbag modules.
Repair or replace any damaged wiring as necessary.

4. Check Seatbelt Buckle Switches

Inspect the seatbelt buckle switches for proper operation.
Replace any faulty switches that may prevent the airbag system from functioning correctly.

5. Examine the SRS Fuse

Locate the SRS fuse in the fuse box (refer to the owner's manual for location).
Inspect the fuse for continuity using a multimeter.
Replace any blown fuses with a new one of the same amperage.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the airbag light remains off.
Conduct a test drive to ensure the airbag system is functioning properly.
