What Fault Does the EPS and ABS Light Indicate?
2 Answers
EPS and ABS lights indicate the following faults: 1. EPS: EPS stands for Electric Power Steering, an abbreviation of the English word electric-steering. If the ESP fault indicator light is on, it may indicate a malfunction in the vehicle's ESP system. It is recommended to immediately reduce driving speed, avoid excessive steering and turning, and have the fault diagnosed with a specialized diagnostic tool at a 4S shop as soon as possible to analyze the specific location of the fault. 2. ABS: ABS is short for Anti-lock Braking System. Its function is to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling and sliding (with a slip ratio of about 20%) to ensure maximum wheel-to-ground adhesion. If the ABS light is on, it indicates an abnormality in the vehicle, and the ABS anti-lock braking system is not functioning properly. Immediate inspection is required to avoid safety issues.
I've been driving for twenty years and often encounter situations where both the EPS and ABS lights come on simultaneously, which is no small matter. EPS stands for Electric Power Steering system, and when its light is on, steering may become difficult; ABS is the Anti-lock Braking System, and when its light is on, the brakes may not prevent skidding, making the car prone to slipping. Common causes include sensors clogged with dust, aging or short-circuited wiring, blown fuses, or a faulty controller. When both lights come on together, it's likely due to a shared power supply issue or a fault in the vehicle's computer. Once, I was driving at night when the lights came on, the steering became stiff, and the brakes failed—I nearly had an accident. I quickly pulled over, checked the fuse box (which was fine), and called a tow truck to take the car to a repair shop for diagnostics. It turned out to be a wheel speed sensor issue. Regular maintenance is crucial; periodically cleaning dust around the wheels can prevent problems. But if issues arise, don't force the drive—professional handling is a priority for safety.
