Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery and wait at least 10 minutes to ensure any residual charge is dissipated.

2. Inspect Airbag Control Module

Locate the airbag control module, usually found under the center console or beneath the driver's seat.
Remove any covers securing the module using a socket set.
Disconnect the wiring harness from the module, ensuring no damage occurs to the connectors.

3. Check Wiring and Connectors

Visually inspect the wiring harness for frays, breaks, or corrosion.
Clean any corroded connectors with electrical contact cleaner and ensure a tight connection when reassembling.

4. Replace Defective Components

If any components (such as the airbag control module or seat belt pretensioners) are found defective during inspection, replace them with OEM parts.
Ensure proper part compatibility with the vehicle's specifications.

5. Reassemble and Reconnect

Reconnect the wiring harness to the airbag control module.
Secure the module back in place with the covers removed.
Reconnect the vehicle's battery.

6. Testing

Use the OBD-II scanner to clear fault codes and monitor the airbag system for any reoccurrences.
Conduct a functional test of the airbag system by performing a key-on engine-off (KOEO) test.
