If your ABS warning light has come on, the anti-lock braking system may not be working correctly. In many cases the car can still brake normally, but emergency braking performance and stability may be reduced.
In many cases, yes for short careful journeys, but you should arrange inspection as soon as possible. Your normal brakes may still work, but the ABS system may not prevent wheel lock under heavy braking.
If the brake warning light is also on, braking feels weak, or the pedal feels unusual, stop driving and seek professional help immediately.
ABS stands for anti-lock braking system. It helps prevent the wheels from locking during heavy braking, which can improve control and stability in an emergency stop.
Many cars still brake normally even when ABS is faulty, but the extra safety support may be lost.
Under hard braking, the wheels may lock more easily if ABS is not functioning properly.
An ABS warning light indicating a fault may cause an MOT failure on vehicles fitted with ABS.
ABS sensor replacement: around £80–£220
Wiring repair: around £60–£180
ABS pump or module repair: around £250–£800+
Final cost depends on the make and model, the specific fault, and whether the issue is electrical or mechanical.
If braking feels weak, unusual or unsafe, stop driving and get help.
If the brake warning light or traction system light is also on, the issue may be more serious.
A diagnostic check is usually needed to confirm whether the fault is a sensor, wiring issue or module problem.
Yes. Low voltage can sometimes trigger ABS and traction-related warning lights.
Only if the actual fault has been fixed. Otherwise the light usually returns.
It may, if the vehicle is fitted with ABS and the warning light shows a fault.
No. The car may still brake, but the anti-lock function may be unavailable in an emergency.
