ABS Warning
The anti-lock braking system is disabled. Regular brakes still work, but wheels can lock under hard braking.
What it means
A fault has been detected in the ABS — commonly a failed wheel-speed sensor. Your normal braking remains, but in a panic stop or on slick roads the wheels may lock and the car can skid instead of pulsing to a stop.
Can you keep driving?
Yes, with extra following distance and gentler braking, especially in rain or snow. Get it checked within days. If the red brake warning light is also on, do not drive — that combination indicates a deeper hydraulic problem.
What to do now
- 1
Drive normally but leave extra stopping distance and brake earlier.
- 2
Check whether the red brake warning light is also on — if so, treat it as a stop-now fault.
- 3
Have the ABS codes scanned; wheel-speed sensors are the usual culprit and are a moderate-cost fix.
Likely causes
- • Failed wheel-speed sensor (most common)
- • Damaged sensor wiring or tone ring
- • Blown ABS fuse or failed ABS module/pump
- • Low brake fluid triggering both systems
Typical fix cost
$100–$300 for a wheel-speed sensor; $400–$1,000+ for an ABS module
