4 Signs of Failing Airbag Sensors You Need to Know

Your vehicle should have working airbags. However, not all vehicle owners are aware if their airbags are working properly. In some cases, they’ll only know that the airbag doesn’t work after a collision, which is the last thing you want to happen. That’s why you need to be mindful of your airbag sensors. 

Airbag sensors are all over the car, and it’s different depending on the car make and model. The main responsibility of these sensors is to detect a crash or collision to trigger the airbags. Usually, they’re located at the front part of the car to detect frontal collisions easily. Most modern vehicles have multiple sensors. 

You don’t want to get into an accident with a faulty airbag. So, don’t let this happen to you; know the signs of failing airbag sensors. 

1. Airbag Light

The most common sign of a malfunctioning airbag sensor is if the light is on or flashing on your dashboard. It means that the airbag function is disabled. Usually, the warning light flashes in a specific way, which is two blinks, then pauses, then blinks again thrice continuously that indicates code 23. Refer to your car manual to know the particular codes. 

2. Drained Car Battery

If your car’s battery recently drained, chances are, the battery of your airbag is also depleted. This is the main reason the airbag warning light flashes on the dashboard. The good news is, you can resolve the problem easily by recharging the battery of your car. However, you need to remove the soft-code error with the use of a diagnostic scan tool. 

3. Faulty Airbag Clock Springs

Your airbag clock springs maintain the consistency between the electrical wiring and the airbag. Over time, the circuit bands wear out, which will result in an airbag code error that will lead to a flashing airbag light. The problem here is that it’s difficult to diagnose this at home, which is why you need to bring the vehicle to a professional to identify the main cause of the issue. Usually, a replacement is the best solution for this. 

4. Airbag Module Damage

The airbag module is located under the front passenger seat. When it’s exposed to light moisture or water, it may start to corrode, and eventually, it will short circuit. When this happens, the airbag light on the dashboard will blink. 

Your airbag sensors play a crucial role in your safety. That’s why being mindful of them is crucial.
