How to repair the car airbag fault light?

1. This car has been dismantled before. If there is an airbag wire at the disassembly position, turn on the car power supply after disconnecting the wire, and the on-board computer will recognize the disconnection of the wire, then light the airbag lamp and save the fault code in the computer.

If this is the case, the solution is relatively simple, mainly after the line is restored, the fault code can be cleared with a computer detector.

2. Airbag-related components fail with the extension of service time, or the airbag light is turned on due to the error of its own internal program.

In these cases, it is necessary to replace the faulty parts before the airbag light goes out.

Airbag maintenance involves a lot of professional knowledge, and the owner may not be able to solve it by himself. But we can try to judge whether the airbag failure caused the airbag light to come on. After all, in some special circumstances, it will also cause the airbag light to light up. For example, disconnect the negative electrode of the battery, and then wait for 5- 10 minutes to power on to see if the fault light is on. If the fault light is not on, it is a false fault. Sometimes the airbag warning light will light up because the battery is low.
