Solution

1. Preparation

Gather tools and materials.
Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver, torx screwdriver.
Ensure the vehicle is parked on a level surface, and the ignition is off.

2. Retrieve and Diagnose Error 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 error codes and record them for further analysis.
Disconnect the scanner once codes are noted.

3. Inspect Airbag System Components

Remove the negative battery terminal to prevent accidental deployment of the airbags.
Visually inspect the airbag connectors under the seats and dashboard for damage or disconnection.
Ensure that all connectors are secure and free of corrosion.

4. Test Airbag System Components

Use a multimeter to check the resistance of the seatbelt pretensioners and airbag modules.
Compare readings against manufacturer specifications (found in the service manual).
If any components are out of specification, replace them accordingly.

5. Clear Error Codes and Recheck System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes from the memory.
Start the vehicle and check if the airbag light turns off. If the light remains on, further diagnosis may be required.
