ABS warning light — what it means

An illuminated ABS lamp usually means anti-lock braking is disabled. Pedal brakes often still work, but wheels can lock on a hard stop — especially in the wet. Lit ABS is also a classic MOT fail.

Also called: ABS

What it means

Anti-lock braking may be disabled. Normal braking usually still works.

What to do first: Drive carefully, especially in wet weather, and get a scan. Can fail MOT if lit.

Common causes

Failed wheel-speed sensor or damaged reluctor ring
ABS pump/module faults
Low system voltage after a weak battery
Wiring corrosion at hubs

Step-by-step

1Drive smoothly and leave extra stopping distance.
2Do not ignore it before an MOT booking.
3Get a diagnostic scan — guessing sensors wastes money.
4Check for related ESC/traction lights; they often share sensors.

MOT note

ABS warning lamp on is commonly an MOT failure for the braking system electronics.
