Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery and wait at least 10 minutes to ensure the system is de-energized before working on the airbag system.
Ensure the vehicle is in a safe and stable position (parked on a flat surface).

2. Retrieve and Clear Error Codes

Use an OBD-II scanner to read any active airbag codes.
Note the codes for reference, then clear them from the system.
Reconnect the battery and start the vehicle to see if the airbag light returns.

3. Inspect Airbag System Components

Tools Required: Multimeter, socket set, torque wrench
Remove the steering wheel cover and inspect the airbag module connections.
Check the resistance of the airbag system using a multimeter; it should typically be between 2-3 ohms.
Inspect seatbelt pretensioner connections under the seats for any damage or disconnection.

4. Repair or Replace Faulty Components

If any components are found to be faulty:
- For damaged wiring: Repair as needed using appropriate gauge wire and connectors.
- For faulty seatbelt sensors: Replace them with OEM parts to ensure compatibility.
- For defective airbag control module: Replace the module with a new one and ensure it is programmed correctly.

5. Reassemble and Test

Reassemble any components removed during inspection and repair, ensuring all connections are secure and torqued to specifications.
Reconnect the battery and perform a test drive to verify if the airbag light remains off.
