What to do if the airbag warning light keeps flickering on and off?
2 Answers
If the airbag warning light sometimes turns on and sometimes off, it indicates a fault in the airbag system. Here are the relevant solutions: 1. Instrument self-check: When entering the car and starting the ignition, the instrument panel will perform an automatic check. After the self-check is completed, the airbag light will automatically turn off, which usually takes about 5 seconds. This is a normal phenomenon. If the airbag light remains on for a long time after the self-check, it can be determined that there is indeed a fault. 2. False fault: If the battery is low on power, it may also cause the airbag warning light to turn on. Additionally, the airbag system may feedback a signal indicating low pressure in a certain airbag, generating a fault code. In this case, simply clearing this fault code will resolve the issue.
I've been driving for over ten years and have seen the airbag light flickering on and off several times. The most likely cause is a loose wiring connector under the seat, especially since we adjust our seats every day, and over time, the yellow connectors can become loose. Last week, my neighbor's car had the same issue, and the mechanic at a roadside shop quickly diagnosed it as a loose passenger seat sensor connector with a scanner—tightening it took just three minutes to fix. However, steering wheel clock spring issues are more troublesome. Last year, my colleague's old car had the light flickering intermittently, and it ended up costing 800 to replace the clock spring. Remember, never kick the wiring under the seat, and water seeping into the rubber covers during car washes can also cause poor contact. Never ignore this light—I once heard about a car where the light went off before an accident, and the airbags didn’t deploy. How terrifying is that?
