First, disconnect your automobile battery’s positive cable. Then, maintain your foot firmly on the brake pedal to shut off the car’s electrical system. The core computer of the car will be reset as a result. Reconnect the cord to re-establish electricity. This should reset the light if the system doesn’t still have a problem.
Step two: You might need to replace the ABS sensor if the light returns after being reset. To do this, unhook the sensor’s wire and detach the housing from the sensor, which should be affixed to the wheel hub. Next, mount and attach a fresh sensor. It’s possible that using the aforementioned technique, you’ll still need to restart the computer.
Step Three: If the light continues to illuminate, you should utilize an ODB code reader to identify the issue because the car still thinks there is a problem that justifies the light. Take your car to a shop to have the issue identified and fixed if you don’t have an ODB code reader.

Why Wont My ABS Light Go Off?
There was a problem with one or more ABS system parts. It may be an erratic issue, such as a voltage drop caused by a faulty battery or an ABS system failure. In either case, it must be reset because it won’t go away.
How Do You Bleed ABS Hydraulic Units?
You must press the air out of the system in order to bleed the hydraulic unit. You simply need to squeeze the air out of the brake line to each brake caliper if you didn’t repair or loosen any hoses at the booster or ABS unit.
The proper size spanner for the bleed nipple is what you require. A second person to depress and hold the brake pedal, as well as a clear Flexi hose that fits on the caliper’s nipple.
The assistance should begin by applying the back brakes, pressing the pedal 48 times until they encounter some resistance, at which point they must maintain pressure. Remove the dust cap, then carefully open the bleed nipple with a flexible hose placed over it. Bubbles and a tiny amount of liquid ought should emerge.
While your aide continues to apply pressure on the brake, close the nipple. Repeat this process until the caliper is clear of all bubbles. Repeat the process for each of the four calipers’ brake fluid levels.
Use a large syringe to suction the air out of the flexible tube end of a caliper if you are having trouble doing so and the braking fluid isn’t coming out. The brake line and caliper will be cleared of air after this procedure.
You will probably require a scan tool to cycle the pump if air got trapped in the ABS hydraulic unit; for details, click this page.
Can You Drive Without ABS?
When you apply too much braking pressure, the wheels will lock up since the ABS isn’t functioning. You might have to pump the brakes in an emergency to counteract the effects of the ABS and lessen wheel lock.
Can I drive my car with the ABS light on?
As regular braking is unaffected by the ABS light, you can continue to operate the vehicle while it is illuminated. However, since your ABS system aids in stopping control and driving without it can be risky, we wouldn’t advise you to do this. You want to know how your car will function if something goes wrong. Without a fully functioning ABS system, your car could not respond to hard braking as it should.
Why are my traction control and ABS lights on?
When a malfunction, a bad wheel sensor, or other mechanical issues are discovered, the ABS and Traction Control lights will illuminate. When coupled with the primary brake light flashing, these warning lights, which by themselves do not indicate anything serious, may indicate a more serious issue.
Here are a total of 14 causes for the traction control and ABS lights to illuminate:
- ABS module malfunction
- computer problems
- broken fuse
- improper wheel-speed sensor
- reduced tire pressure
- the steering angle sensor is faulty
- brake fluid is low
- incorrect steering rack
- faulty pumps and valves
- erroneous wheel alignment
- sludge and detritus
- battery voltage is low
- Slouch mode
- OFF the traction control
Do not panic if these lights come on while you are driving because your car’s braking system will still function. Just be careful not to cause any wheel slippage by slowing down and applying gentle braking. Having an OBDII scanner on hand is one of the best strategies for handling this circumstance. You could use this to decode codes, locate triggers, and turn off the ABS and TCS lights. But if it is not possible to reset the warning lights, take your car to a professional for a complete diagnosis and repair.
Q: Is it safe to drive a car with an ABS light on?
Yes, it is secure. Even having the ABS light on, the car brakes will continue to function normally when braking. But in cases of hard braking, the brakes will lock up, causing the wheels to skid. When you apply hard braking on ice during the winter, your ABS system is crucial to prevent your wheels from locking up.
Driving with the ABS light on in the winter is risky since your car won’t be able to withstand emergency severe braking. The safety feature gives you steering control by reducing your stopping distance and safeguarding you from mishaps.
Q: How much does it cost to fix the ABS system?
Ans: If you include the price of an ABS diagnosis and labor fees, it will cost about $200. The estimate, which is location-specific and excludes taxes and fees, is available here.
However, depending on the ABS module component, there may be an additional cost of $200 to 950 if you need to replace the ABS system. Many mechanics will repair your ABS for a total of $340 to $1100.
Q: Can Low brake fluid cause ABS light to come on?
Yes, when there is insufficient brake fluid in the ABS fluid reservoir, an ABS light will illuminate. You have an abnormally low fluid level, according to the warning light. Check to see if the alert goes away by shutting off the engine and starting it again. If not, look to see if the light is flashing. If so, it indicates that the brake fluid level is only a little bit low.
Q: Can worn brake pads cause ABS light to come on?
Ans: No. The ABS light won’t turn on because your brake pads are worn out. A blown fuse, an irregular wheel sensor, and low brake fluid levels all cause the light to come on. As a safety measure, it’s wise to change old brake pads in order to boost stopping power. To increase your car’s braking effectiveness, replace worn brake lines.
Q: What can cause ABS to fail?
Unless the ABD controller is malfunctioning due to one or more sensors or defective sensor connections, ABS rarely goes wrong. The most frequent reason is that metal shavings, debris, or corrosion have contaminated the sensors. Only after you slam on the brakes and realize that the wheels are locking up as you drive will you become aware of a malfunction.
How long should the ABS light be on when driving?
The anti-lock braking system, or ABS, keeps your car’s tires in touch with the pavement as you use the brakes. By preventing the wheels from locking up, which could cause uncontrollable skids, it works. The primary goal of ABS is to enhance vehicle control during hard braking, particularly on slick or loose surfaces. It can help, but it doesn’t always shorten the stopping distance.
The following information about ABS safety is provided:
Every time the ignition is turned on, the ABS does a self-test. The warning light will flash once your car starts, and if the computer detects a problem, it will stay on. If you see the light flash right away after starting the car, your car is only performing a self-check.
When the warning light illuminates while you are moving, the ABS is not functioning properly. If you have to stop suddenly, your brakes will still function, but the ABS may not. You must have a mechanic diagnose the ABS light problem as soon as possible if the light does not go out. The ABS is a crucial safety component to maintain because it assists with vehicle control and stopping distancesyou never know when you’ll need it.
Your car is no longer safe to drive if the ABS and brake system lights come on simultaneously. This indicates a significant issue with the brake system, and continuing to drive puts you and other drivers in danger of a collision.
The brake pedal will pulse as you apply forceful braking and your ABS activates. This indicates that the ABS is operating normally and is entirely normal. This pulsing is produced by the ABS in conjunction with your braking system to prevent the wheels from locking up. Keep your foot on the stop pedal as soon as you notice this pulsation and let the system take over. All you have to do is focus on safe steering.
Driving is not advised if your ABS warning light is on since it indicates a malfunction. It’s possible that hard braking will cause your car to handle stopping on slick surfaces differently than it was intended to. If both of your brake system and ABS lights turn on, you need to immediately stop driving since there is an emergency. Have a qualified mechanic, such as one from YourMechanic, inspect your whole brake system.
Why is my ABS light on even though I just changed my brake pads?
Following a brake job, the following problems may cause your ABS and Traction Control light to illuminate: brake fluid that is tainted. During service, the wheel speed sensor came loose. The cables for the sensor connector were not reattached to their initial location.
What does it cost to repair the ABS light?
The initial diagnosis will cost you roughly $100 from a qualified mechanic. Because so many ABS parts are easily accessible, labor costs for the majority of repairs are typically in the $100150 area. A standard ABS sensor will cost between $80 and $125, however on some makes and models (GM, Ford, and others), the sensor is included in a hub/bearing assembly, raising the cost to around $350. Parts costs rise into the $500 to $800 area for more serious problems like those with the ABS pump or computer.
Can ABS be harmed by a low battery?
The ABS light can illuminate as a result of a poor battery. The ABS light could also come on if your brake light is broken or burned out.
Will a car in Virginia that has the ABS light on pass inspection?
One approach to safeguard both yourself and other people is to have your car inspected in Virginia.
Your car’s brakes must be in good working order in order to meet the yearly standard.
The state inspection may also reveal a firm brake pedal or a car that has trouble stopping.
A vacuum issue may be to blame for this. Electric pressure pumps have replaced older parts like vacuum brake boosters in many vehicles.
Several factors might cause brake lines to twist. Maybe the person replacing the caliper turned it too many times.
The inspectors check to make sure the brake hoses aren’t being rubbed against, beginning to wear through, or showing signs of having too many cracks.
At 3/32 or 4/32 of an inch, we would start to suggest new brakes, but they must be less than 2/32 to fail inspection. Brakes will technically pass at 2/32 of an inch, however depending on your driving circumstances, they might not in a week or a month.
According to the recommendations of the manufacturer, rotors must be a specific thickness.
You can have a seized caliper or a piston that is pushing in but a caliper that isn’t sliding. This indicates that only half of the wheel’s braking power is being applied since one pad isn’t making contact with the rotor. When we find a lot of rust built up on the rotor, it’s a solid sign that the brakes aren’t operating well.
Additionally, vehicle safety examiners look to see if the parking brake can hold on a slight incline.
Some modern automobiles have electronic parking brakes. They even lack a handle that you can pull up; instead, a computer controls them.
The electronic parking brake must be checked in a variety of ways during the state inspection.
Another element that is examined is the anti-lock braking system (ABS) light. Even with the yellow ABS light on, a car can still pass inspection. However, if the red brake light is illuminated, it won’t pass as there might be an issue with the fluid or system of the parking brake.
Inspectors may test drive the vehicle if they suspect a mechanical problem.
