What it means
ABS helps prevent wheel lock-up during hard braking. When the ABS light is on, the system may be disabled, but your regular brakes usually still work. The symbol often shows the letters ABS inside a circle.
What to do first
- Check whether the red brake warning light is also on — that is more urgent.
- Test braking gently in a safe place if you are unsure how the pedal feels.
- Avoid hard emergency stops if you can; increase following distance.
- Have the ABS system scanned for fault codes.
Common causes
- Faulty wheel speed sensor
- ABS module or wiring fault
- Low brake fluid on some vehicles
- Blown fuse or control unit issue
- Recent battery disconnect or voltage problem
ABS vs brake warning light
ABS alone usually means anti-lock assist may be unavailable. A red brake warning can mean low fluid, parking brake, or a hydraulic fault. If both lights are on, inspect the brake system before continuing.
ABS Warning Light FAQ
Can I drive without ABS?
Often yes if normal braking feels fine, but stopping distances on wet or icy roads may increase. Drive cautiously and repair the system soon.
Will ABS turn off after I restart the car?
Sometimes a temporary fault clears, but if the light returns, the system should be diagnosed.
