Anti-lock braking system warning light: meaning and what to do

Anti-lock braking system

The exact symbol can vary between makes and models. Also check the message displayed by the vehicle.

How urgent is it?

Prompt inspection; with a brake warning or abnormal braking, stop safely.

How to recognise it

ABS lettering in a circle.

What it can mean

Anti-lock operation may be unavailable. Basic braking can remain, but do not assume all braking functions are normal.

What to do

Increase following distance and avoid abrupt braking. Arrange checks; stop and seek assistance for a red brake warning or abnormal pedal feel.

Before clearing the light or codes

Photograph the dashboard message and save all codes, the reporting module, fault status and freeze-frame data. Clearing can remove useful evidence without repairing the cause.
