PHP editor Apple will explore the potential causes of this problem in detail and provide solutions to help you solve this problem.
What should I do if the abs light is on and there is no fault? Write an answer
That requires a detailed analysis of the specific situation.
1. The ABS light is always on to indicate the anti-lock braking system alarm. Under normal circumstances, the light will come on when the ignition switch is turned on or the engine is started, and the system will enter the automatic detection program. After the detection is completed, the light will go out.
2. There are two possibilities. If the car can still be braked by the conventional braking system while driving and only the ABS warning light is on, it means there is a fault in the ABS system. You should ask a professional to check it with a diagnostic tool as soon as possible to determine that it is the ring gear. , sensors, wiring and other problems;
3. If the ABS warning light and the braking system warning light light up at the same time while driving, it means that both the ABS and the braking system are faulty, and the braking characteristics will change. If it is the latter, you must stop driving immediately, check the brake fluid level, and ask a professional for maintenance.
4. If the fluid level is normal, if the ABS system adjustment function fails, it means that the ABS light is on, and only the ordinary braking system works, which can easily cause the rear wheel to lock up quickly during braking, causing sideslip. At this time, you should drive with caution and perform repairs as soon as possible.
