ABS Warning Light On: Is It Safe to Drive?
An ABS light means the anti-lock system is switched off. Normal brakes still work, but the wheels can lock in a hard stop. Drive carefully with extra following distance, and do not drive if the red BRAKE light is on as well.
Can I drive it? Drive with care
You can drive carefully with normal brakes and extra following distance. If the red BRAKE light is on as well, do not drive.
Typical repair cost
$100-$300 for a wheel speed sensor, $30-$150 for a fuse or connector, $600-$1,500 for an ABS module.
General US estimates, not quotes. Prices vary by region, vehicle and shop.
Low brake fluid can also switch the ABS light on, so see brake fluid leak if the level keeps dropping. A pedal that feels different is covered under spongy brake pedal. If the car pulls when you brake, read brake pulling. To narrow down the cause, ask AI Car Mechanic about your exact car.

Frequently Asked Questions
Is it safe to drive with the ABS light on?
Yes, with care. The brakes work normally but without anti-lock protection on slippery roads. If the red BRAKE light is also on, stop.
Why did it come on after a tire change?
A damaged or disconnected wheel speed sensor or its tone ring during the work is a common cause.
What does the ABS sensor warning light mean?
The anti-lock system has switched itself off. A bad wheel speed sensor is the most likely cause, followed by a faulty ABS module, a blown ABS fuse or low brake fluid.
How is an ABS problem diagnosed?
The ABS codes are read with a scan tool, then the wheel speed sensors are checked for damage or dirt, along with the ABS fuse and the brake fluid level. The ABS module is tested last.
