What is the reason for the ABS warning light to illuminate after a vehicle inspection?

[JudeAnn]

The reason for the ABS warning light to illuminate after a vehicle inspection is: During the tailpipe emissions test, only the front wheels rotate for front-wheel-drive vehicles, and only the rear wheels rotate for rear-wheel-drive vehicles, causing the system to perceive an ABS fault. Other reasons for the ABS warning light to illuminate include: wheel speed sensor issues, ABS wiring problems, ABS pressure modulator solenoid valve faults, and ABS computer malfunctions. ABS stands for Anti-lock Braking System, and its function is: During braking, it automatically controls the braking force to prevent wheel lock-up, ensuring maximum traction between the tires and the road surface. The indicators in a vehicle and their respective functions are: 1. Engine warning light: Indicates an engine fault; 2. Battery warning light: Indicates depleted battery or alternator fault; 3. Oil pressure warning light: Indicates insufficient engine oil.
