How to Solve the Issue of the Car Airbag Light Always Being On?
2 Answers
Solutions for the car airbag light being on are as follows: 1. The airbag light being on indicates a fault in the airbag system. Although it does not affect normal driving, the airbags may not deploy properly in the event of a collision. 2. It is recommended to visit a 4S shop for computer diagnosis and troubleshooting: Use a fault detector to perform a computer test on the airbag system and read the fault codes. Once the specific meanings of the relevant fault codes are identified, the fault range can be narrowed down for appropriate judgment. 3. In most cases, the issue is caused by short circuits or open circuits in the system wiring, and reconnecting the wiring properly can resolve the problem.
Last time I encountered an issue with the airbag light being on, I figured out a few key points myself. First, check the yellow connector under the seat—many cars have wiring harnesses that get loosened when the seat is moved, and simply unplugging and replugging it a few times can fix the issue. If that doesn’t work, you’ll need to inspect the sensors. There’s a pressure sensor under the passenger seat, and placing heavy objects on it or damaging the wiring can also trigger the light. Here’s a lesser-known fact: the light will turn on after disconnecting the battery, and you’ll need a diagnostic tool to reset it. My neighbor’s car had an error because the airbag control module got damp—when we took apart the steering wheel, we found water had seeped into the connector. It’s best not to attempt these repairs yourself, as they involve the safety system. I recommend first checking the manual to rule out user error, and if that doesn’t help, take the car to a dealership immediately for a computer scan to read the fault codes. Repairing airbag-related issues can be much more expensive than you’d expect.
