Can you drive with ABS failure?
Yes. You can typically keep driving, but ABS failure should be treated as a warning—the car can be braked without ABS, but you lose anti-lock function and may experience wheel lock during hard braking. Have the system checked as soon as possible.
What ABS does and what a failure means
ABS, or anti-lock braking system, helps prevent wheel lock during emergency or heavy braking by modulating brake pressure. When the system fails, the brakes still work, but you lose this automated support, which can increase stopping distances and reduce steering control on slippery surfaces.
Indicators of an ABS problem
Common signals that the ABS is not functioning correctly include the ABS warning light staying on, warning messages in the instrument cluster, a braking pedal that feels different or pulses, or a car that pulls to one side during braking, especially on wet or icy roads.
- ABS warning light illuminated on the dashboard
- Brake pedal feels spongy, stiff, or pulsates when braking
- Vehicle pulls to one side while braking or braking distances appear longer on slick surfaces
- Flicker or buzzing from the brake system; diagnostic trouble codes related to wheel speed sensors
If any of these signs appear, plan a service appointment promptly. ABS can fail due to faulty wheel-speed sensors, blown fuses, or issues with the hydraulic pump or control module.
How to drive safely when ABS is not working or warning light is on
In the moment you should adjust your driving to compensate for the loss of ABS. The following steps help minimize risk on the road.
Immediate precautions
- Maintain a longer following distance and reduce speed to allow more time to stop.
- Avoid sudden, heavy braking; apply steady, progressive braking with your foot firmly on the brake pedal. If the wheels begin to lock, ease off briefly and reapply pressure.
- Use lower gears on declines to help braking without relying on ABS.
- Be extra cautious on wet, icy, or uneven surfaces where wheel lock is more likely.
- Seek a safe place to stop and have the system diagnosed as soon as possible.
Note: Some newer cars may retain some braking capability if ABS fails, but training and conditions vary by vehicle. Always consult your owner's manual for model-specific guidance.
Maintenance and prevention
Preventing ABS failures is largely about routine maintenance and early diagnosis of sensor or hydraulic problems.
Preventive steps to reduce risk
- Regularly inspect wheel-speed sensors and wiring for damage or corrosion.
- Keep brake fluid at the proper level and condition; contaminated fluid can affect braking performance.
- Replace worn brake pads promptly and check the brake system for leaks or air in lines.
- Ensure fuses and the ABS module are in good condition; have the system scanned for trouble codes during service.
Proactive maintenance helps ensure ABS stays functional and reduces the likelihood of unexpected alarms or failures.
Summary
ABS failure does not render a vehicle undrivable, but it removes a key safety feature. You should slow down, increase following distance, and have the system inspected promptly. Regular maintenance can prevent ABS problems and keep braking performance predictable in all conditions.
Is ABS failure serious?
If the ABS pump fails, braking power can disappear when the ABS activates, often going unnoticed until needed. Given the risks, have the system checked by a professional immediately if you have any concerns.
What if your ABS fails you should?
Although it may still be safe to drive with the ABS light on, we recommend getting your vehicle checked by a professional mechanic so they can identify the issue that's causing the light to turn on.
Is it expensive to fix an ABS problem?
Yes, fixing an ABS system can be expensive, as costs vary widely depending on the specific problem, your vehicle's make and model, and the repair options you choose. While a simple wheel speed sensor might be cheaper to replace, a failing ABS control module can cost from a few hundred to over two thousand dollars, especially for new parts.
Factors that influence cost
- Part replacement vs. repair: Replacing the entire module is often more expensive than having the module itself repaired.
- Type of repair: A simple fix like cleaning a wheel sensor can be cheap, but if the sensor is stuck or the module itself is faulty, the cost increases.
- Vehicle make and model: Luxury or high-performance vehicles may have more complex and expensive systems.
- Labor costs: The time needed for diagnosis and the repair itself can add to the total expense.
Potential cost ranges
- ABS wheel speed sensor: These parts are generally less expensive, ranging from about $100 to $200 each, though labor can increase the total cost significantly.
- ABS control module: Costs for replacing this part can range from $40 to over $2,290 for a new unit, depending on the vehicle.
- Used or rebuilt parts: You can save money by buying a used or rebuilt module, which typically costs between $90 and $200, but ensure the part comes with a warranty.
- Module repair services: Some companies specialize in rebuilding modules, which can be cheaper than buying a new one, with prices around $150 to $200 plus shipping.
Ways to save money
- Get a diagnostic scan to identify the exact problem, which can help you avoid paying for unnecessary repairs.
- Compare quotes from different mechanics, including independent shops that may have lower prices than dealerships.
- Consider installing a used, tested module with a warranty instead of a new one.
- Research specialized repair shops that can bench-repair the module instead of replacing it entirely.
Can you drive if ABS is not working?
Yes, you can typically drive with an ABS fault, but you must be cautious because your normal brakes are still functional, and the ABS system is disabled. This means your car may not stop as effectively in an emergency or on slippery surfaces like rain or snow, potentially leading to locked wheels and loss of steering control. It is crucial to drive carefully, avoid sudden stops, and get the system inspected by a professional as soon as possible.

What to do when the ABS light is on
- Drive with caution: Avoid sudden braking, high speeds, and driving in adverse weather conditions like rain or snow.
- Maintain extra distance: Give yourself more room to stop than usual.
- Check for other warning lights: If you see a red brake warning light come on at the same time, stop driving immediately and call for assistance.
- Check brake fluid: If you are comfortable, check your brake fluid level. Low fluid can be a sign of a leak, and topping it off may be a temporary fix, but the underlying issue still needs professional attention.
- Schedule a professional inspection: Get your vehicle to a mechanic to diagnose the exact problem, which could be anything from a dirty sensor to a more complex issue.
