If you’re like any other driver, you hate having all sorts of lights (other than the speedometer and fuel gauge) light up on your dashboard. It’s just very annoying, while also technically being proof that there’s something wrong with the system. Case in point, the airbag light. Fortunately, there are different methods you can use to try and fix it. If these fixes don’t actually work, you might need to take your car to a garage that offers airbag repair services to properly diagnose and fix your issues.

If you decide to diagnose and test your airbags yourself, you need to remember:

It’s All About the Sensors

Most modern cars have a relatively simple airbag system. A few sensors, a module that interprets signals, and the airbag with a component that allows for its rapid deployment comprise this system. These sensors can wear out over time, and these are what you should look out for.

Check if your car has a passenger occupancy sensor. This is a weight-sensitive component which notices if there’s someone sitting on the passenger seat. Constant forward and backward adjustment of the seat can cause the sensor’s wiring harness to stretch and fray. This is one of the most common airbag issues in modern vehicles. Obviously, a sensor that doesn’t work means the wiring might be damaged. Should you not be confident in your skills, always consult a professional.

Here’s a quick fix you can try. If the light comes on, trace the airbag’s connection back to the sensor in the passenger seat. Look for a multi-pin electric plug and socket below it. See if it has been dislodged, and if it was, push the plug and socket back together to clear the error message on your dashboard. If this solution does not yourk you many want to look elsewhere.

Try The Vehicle’s ECU (Electronic Control Unit)

The car’s ECU might also be to blame. Try bringing your car to a professional and have him run a diagnostic on the ECU chip. The ECU is where all data regarding the car’s electronic systems is processed and stored. When the airbag light is still on even after the bag has deployed or haven’t been activated at all, there are two possible causes: either the airbag system has been deactivated and faulty, or the computer made an error and the airbags are correct.
