Addressing Wiring Problems
Check the wiring connections under the dashboard. Loose connections can cause the airbag light to turn on. Ensure all plugs are tightly connected. Sometimes, dirt can get into the connections. Clean them with a soft brush. Make sure the wires are not bent or broken.

Airbag Module Concerns
The airbag light might be on due to a faulty module. The module controls the airbag system. Check for any error codes first. These codes help find the problem. Next, inspect the module’s connections. Loose or damaged wires cause issues. Use a diagnostic tool to test the module. Follow the tool’s instructions. If the module shows an error, it might need replacement.
If testing shows the module is faulty, replace it. First, disconnect the battery to avoid any risk. Then, locate the airbag module. It’s usually under the driver’s seat. Carefully remove the old module. Be gentle with wires. Install the new module in the same place. Connect all wires properly. Finally, reconnect the battery and test the system. The airbag light should turn off. Always follow safety guidelines during replacement.

Steering Wheel Airbag
The clock spring is inside the steering wheel. It connects the airbag to the rest of the car. Worn out clock spring can cause the airbag light to turn on. Check the clock spring for wear and tear. Listen for clicking sounds when turning the wheel. This could mean the clock spring is damaged. A damaged clock spring needs replacing. This might fix the airbag light issue.
Disconnect the car battery before fixing the clock spring. This prevents the airbag from deploying. Remove the steering wheel to access the clock spring. Unplug the old clock spring carefully. Plug in the new clock spring. Secure it in place. Reattach the steering wheel. Reconnect the car battery. Check if the airbag light is off. If not, seek professional help.
