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.

How is the ABS light code reset?
Put your hand on the brake pedal and depress it. When you hear a click, you should let off the brake. Within three seconds, eight times, press and release the brake pedal. When you have passed the light, the ABS light will stop flashing, remain lit for one second, and then flash four times.
Why are my traction control and ABS brake 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
- improper wheel-speed sensor
- reduced tire pressure
- the steering angle sensor is faulty
- incorrect steering rack
- faulty pumps and valves
- erroneous wheel alignment
- battery voltage is low
- 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.
The ABS light is on for what reason?
The standard brakes on your automobile should still function properly, however the antilock system that prevents wheels from locking up while braking will not. Additionally, because traction control and stability control rely on the same wheel-speed sensors as the antilock system, those features will also be disabled if your car has them.
All vehicles made in 2012 and later are obliged to feature traction control, ABS, and stability control. All or some of those features can be found in many vintage vehicles.
Every time you start your automobile, the ABS light (often yellow, amber, or orange) should briefly illuminate as a system check. If the light continues to illuminate, the system has been shut down because something isn’t operating properly.
With ABS, sensors that are put on each wheel track how quickly the wheels are spinning. When braking, if one wheel is rotating more slowly than the others, it means it is locking up, which could lead to skidding and a loss of steering control. In order to prevent further wheel locking, ABS is designed to quickly “pump the brakes at the locking wheel, allowing it to spin so that the driver retains braking and steering control.”
What causes this is as follows:
- a system fuse that has blown
- a road grime- or damage-covered wheel-speed sensor
- between the sensors and the ABS controller, a broken wire
- A malfunctioning ABS controller
An ABS sensor warning light can also be activated when a pump and valve that apply the proper amount of braking fluid pressure to each wheel to prevent locking do so.
If the regular brakes’ red warning light illuminates, your car is likely losing braking fluid or the brakes are so worn that you can’t stop as quickly as usual. Any of such circumstances calls for prompt attention and perhaps repairs.
What is the time required to reset the ABS light?
The light can be reset in one of two ways: The simplest method is to unplug the battery terminal cables while the ignition is off, starting with the negative battery terminal and moving up to the positive line. The two terminals should be connected to one another using a battery jumper lead. Turn the ignition on for 20 to 25 minutes while opening the driver’s door.
When the ABS light is on, can I drive?
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.
If I remove the ABS fuse, what happens?
The ABS mechanical module still receives the braking pressure. But if the fuse is taken out, the module won’t be able to activate the brakes. The module can still have a mechanical issue.
Can a blown fuse turn on the ABS light?
If your car doesn’t exhibit any of the symptoms listed above but the light still illuminates, there may be a problem with the bulb check.
This could be a bug or, more frequently, a blown fuse.
The light may intermittently turn on and off due to a blown ABS fuse.
Fuses are simple to blow, therefore occasionally checking is a quick cure.
How much does fixing the ABS light cost?
How much does it cost to fix a lighted 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.
What location do the ABS sensors have?
An “ABS sensor,” sometimes known as a wheel speed sensor, is a component of the anti-lock braking system (ABS). It can be found on the tires (near the brake rotors for the front tires and in the rear end housing for the rear tires). The wheel speed sensor’s responsibility is to continuously track and communicate to the ABS control module the rotational speed of each tire. When you press the brakes, your automobile won’t slide or skid thanks to the ABS safety system. The ABS control module gets the speed data from the speed sensor and transmits the appropriate pressure to each tire when the brake is applied to avoid any sliding or skidding (wheels locking up).
Each tire on vehicles with rotors in each one will also include a speed sensor. There will be one sensor in the back and two in the front of the tires on cars with rear drum brakes (as opposed to rotors). The ABS warning light will illuminate and the ABS will be turned off when one or more of these sensors are malfunctioning. Although the tires may slide when you apply the brakes, especially on slick conditions, you will still be able to slow down and stop your automobile.
