Step One: Disconnect the positive cable from your car battery. Then press and hold the brake pedal to drain the vehicle’s electrical system. This will reset the vehicle’s central computer. Reconnect the cable to restore power.
If there is a problem with your anti-lock braking system (ABS), a corresponding light will illuminate on your dashboard. The light is displayed as the acronym “ABS”. Your ABS is there to keep your car from skidding dangerously when braking.
Will disconnecting the battery reset the ABS light? Yes, if the car battery is disconnected long enough, the ABS light will reset.
The four most common reasons that usually cause this light to illuminate are a faulty ABS module, low fluid reservoir levels, faulty wheel speed sensors, or the system is off. Your ABS actually shares some important components with another system in your vehicle: your traction control system.
The ABS and traction control lights illuminate anytime the vehicle’s computer or PCM detects a malfunction, defective wheel sensor, or other mechanical fault. These warning lights mean nothing serious on their own, but can indicate a more serious problem when coupled with the main brake light going off.
If the TCS and ABS warning lights illuminate along with the red master brake warning light, you should not drive the vehicle until the problem is resolved. Your entire braking system is affected and may not be able to stop your vehicle when you need it. Have your vehicle towed to a workshop.
If your traction control light does not turn off, there are several reasons that could potentially explain why. The most common reason is you are trying to ride on slippery surfaces.
If the ABS light illuminates on the instrument panel, our technicians recommend checking the battery first. A low battery may cause the ABS light to come on. A non-working or burned out brake light can also cause the ABS light to illuminate.
Q: Can low brake fluid cause the ABS light to come on? Answer: Yes, an ABS light will illuminate when the brake fluid level in the ABS reservoir is low. The warning light means you have an abnormally low fluid level. Turn off the engine and restart it by turning it back on to see if the warning clears.
Unfortunately, the only way to check if the problem is with the ABS is to read your car’s codes. AutoZone can scan your codes as part of our Fix Finder service, or you can do it yourself if you already have a scanning tool.
Your vehicle may not stop on slippery surfaces as intended under hard braking. If both your ABS light and your brake system light come on, this is an emergency and you must stop immediately. Have your entire braking system checked by a certified mechanic, e.g. B. one from Vermin Club.
