Why Is My ABS Warning Light On?
The ABS Warning Light means your vehicle's Anti-lock Braking System has detected a fault. Your normal brakes will usually continue to work, but the ABS safety feature may no longer prevent the wheels from locking during hard braking.
No OBD scanner required.
Immediate Answer
What Does the ABS Warning Light Mean?
The ABS (Anti-lock Braking System) Warning Light indicates that the system has detected a malfunction and has been temporarily disabled. While your standard hydraulic brakes will usually continue working, features that rely on ABS—such as emergency anti-lock braking and, on many vehicles, stability or traction control—may not function properly.
The issue can be caused by something as simple as a faulty wheel speed sensor or as complex as a failed ABS control module. The only reliable way to identify the exact problem is by reading the vehicle's diagnostic trouble codes.
Is It Safe to Drive?
Can You Drive With the ABS Warning Light On?
- Usually yes — but drive with extra caution.
- In most cases, your normal brakes will still work.
- During emergency braking, the wheels may lock up, reducing steering control and increasing stopping distance—especially on wet, icy, or loose road surfaces.
- If the Brake Warning Light is also illuminated, the brake pedal feels soft, or braking performance has changed, stop driving and have the vehicle inspected immediately.
Arrange a diagnosis as soon as possible, even if the vehicle feels normal.
Common Causes
Most Common Causes of the ABS Warning Light

| Faulty ABS hydraulic pump | High |
| Low brake fluid level | High |

*The exact cause depends on your vehicle, stored diagnostic codes, and whether other warning lights are also present.

F.A.Q.
Frequently Asked Questions
Can I drive with the ABS Warning Light on?
Usually yes, because your normal brakes should still function. However, the anti-lock braking system may be disabled, so drive carefully and avoid hard braking until the issue is diagnosed.
What causes the ABS Warning Light to come on?
Common causes include a faulty wheel speed sensor, damaged sensor wiring, low brake fluid, an ABS pump problem, or a malfunctioning ABS control module.
Does the ABS Warning Light mean my brakes have failed?
Not necessarily. In most cases, your standard brakes still work, but the ABS feature is unavailable. If the Brake Warning Light is also on or braking performance changes, stop driving immediately.
Can the ABS Warning Light reset itself?
Sometimes. If the fault is temporary, the light may turn off after restarting the vehicle or completing several drive cycles. However, the stored fault should still be checked to prevent future problems.
