Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the negative battery terminal to avoid accidental airbag deployment.

2. Scan and Clear Codes

Use an OBD-II scanner to retrieve airbag-related fault codes.
Note any specific codes and clear them from the system.
Reconnect the battery and check if the airbag light re-illuminates.

3. Inspect Airbag Connectors

Locate the airbag connectors under the seats and near the steering column.
Disconnect the connectors carefully and inspect for corrosion or damage.
Clean the connectors with electrical contact cleaner and reconnect them securely.

4. Check Seatbelt and Pretensioner Systems

Inspect the seatbelt latch and pretensioner for proper function.
Ensure that the seatbelt is not frayed or damaged.
Replace any faulty seatbelt components found during inspection.

5. Replace Faulty Airbag Module (if applicable)

If diagnostic codes indicate a faulty airbag module, proceed to replace it.
Remove the steering wheel or dashboard cover to access the module.
Disconnect the old module and install the new module, ensuring all connections are secure.

6. Final Check

Reconnect the battery terminal.
Start the vehicle and verify that the airbag light is no longer illuminated.
