ABS Warning Light
Toyota Vehicle
Severity: ModerateWhat Does This Error Mean?
The ABS warning light means the anti-lock braking system has detected a fault. Normal brakes still work — only ABS is disabled. Common causes are a dirty wheel speed sensor or low brake fluid.
Affected Models
- Toyota Camry
- Toyota Corolla
- Toyota RAV4
- Toyota Highlander
- Toyota Tacoma
- All Toyota vehicles
Common Causes
- Wheel speed sensor dirty or failed
- ABS module fault
- Low brake fluid level
- Damaged tone ring on wheel hub
- Wiring issue to ABS sensor
How to Fix It
-
Check brake fluid level.
Low fluid triggers the ABS light. Top up to the MAX line with DOT 3 or DOT 4.
-
Check wheel speed sensors for dirt.
Sensors near the wheel hub get covered in road grime. Clean with a cloth — do not use solvents.
-
Have the ABS codes read.
A scan tool can identify which specific sensor or component has failed.
-
Try turning the car off and on.
Temporary sensor glitches sometimes clear with a restart.
Frequently Asked Questions
Can I drive with the ABS light on?
Yes. Normal brakes work fine. Only the anti-lock function is disabled. Drive carefully on slippery roads — wheels may lock during hard braking.
Is the ABS light an MOT/inspection failure?
In many countries/states, yes. The ABS system must be functional to pass inspection.
