Fault: airbag failure warning light suddenly lit.
A Flying car user reflects the car's airbag failure warning light suddenly lit.
Connect the fault diagnosis device to detect the airbag control system, the results found the right front impact sensor related to the fault code. After the sensor was replaced, the airbag failure warning light was extinguished. But the vehicle used two days after the airbag failure warning light re-lit. Connect the fault diagnosis machine to read the fault code with the front. The maintenance personnel suspect that there is a problem with the associated harness, and the harness is carefully checked, but no problems are found. As the airbag system structure is relatively simple, since it has been determined that the collision sensor is no problem, and the route is normal, so the problem appears in the airbag computer.
Finally, after the replacement of the airbag computer failure to solve.
Fault: ABS fault warning light is on
Fewer users reflect the ABS fault warning light on the dashboard.
Connect the fault diagnosis device to the ABS control system to detect, the device prompts the right front wheel speed sensor signal is bad. After careful examination, found that the sensor head has a lot of metal foam. Since the wheel speed sensors are electromagnetic induction sensors, it is these metal powder affect the sensor signal output.
The sensor to clean up, and the fault code cleared, troubleshooting.
