Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety glasses.
Ensure the vehicle is parked on a flat surface, and the ignition is turned off.
Disconnect the negative terminal of the battery and wait at least 10 minutes to allow for capacitor discharge.

2. Read and Clear Diagnostic Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the “ON” position without starting the engine.
Retrieve any stored airbag diagnostic trouble codes (DTCs) and write them down for reference.
Clear the codes using the scanner and turn off the ignition.

3. Inspect Connections

Recheck the connections under the front seats:
- Remove the seat cushions if necessary to access the airbag connectors.
- Ensure all connectors are securely plugged in, and there is no corrosion or damage.
Reconnect any loose connections and use electrical cleaner if corrosion is found.

4. Check the Airbag Control Module

Locate the airbag control module, typically found under the center console or under the dashboard.
Inspect for any visible damage or loose wiring.
If necessary, remove the module and check the connectors for continuity using a multimeter.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Turn the ignition to the “ON” position and monitor the airbag light.
If the airbag light remains off, perform a test drive to ensure the light does not reappear.
