What are the troubleshooting methods for ABS anti-lock braking system?

[VanAdam]

ABS anti-lock braking system troubleshooting methods include the following: 1. If the warning light does not illuminate when the ignition is turned on, or remains lit without turning off, or lights up while driving, it indicates a system malfunction. There are two possibilities: if only the ABS warning light is on while driving, it means there is a fault in the ABS system, but the vehicle can still rely on the conventional braking system for braking. Professional repair should be sought as soon as possible. 2. If both the ABS warning light and the braking system warning light illuminate simultaneously while driving, it indicates faults in both the ABS and braking systems, and the braking characteristics will change. In the latter case, driving must be stopped immediately to check the brake fluid level. 3. If the fluid level is below the "MIN" mark, driving must not continue, and new brake fluid should be added or replaced immediately. 4. If the fluid level is normal, it may indicate a fault in the ABS system, meaning the ABS regulation function has failed. In this case, only the ordinary braking system will work, which can easily cause the rear wheels to lock up quickly during braking, leading to skidding.
