If you don’t have a diagnostic tool, you might be able to reset the Sonata’s ABS light by unplugging the battery for a short while. Before removing the cable from the battery’s positive terminal, disconnect it from the negative terminal. To remove any remaining electricity from the system when the battery is unplugged, turn on the headlights and repeatedly push the horn button. Reconnect the batteries in reverse order, starting with the positive cable and moving to the negative cable, after around 15 minutes.

Hyundai Sonata: Meaning & Diagnosis of the ABS Light
The ABS light on your Hyundai Sonata illuminates when a self-diagnostic cycle is unsuccessful. When it’s on, it’s clear that the Sonata lacks anti-lock brakes and the security they offer.
When braking, the ABS system in your Sonata uses a network of sensors to calculate wheel speed. It will apply the most amount of brake to a wheel if it begins to lock up in order to prevent it from slipping.
A vehicle will slow down more quickly with turning wheels than with locked wheels. Additionally, skidding tires result in flat areas on the tire, which can be uncomfortable and hazardous in and of itself. The fact that ABS has been available for so long means that many drivers have never operated a vehicle without it. It also enables you to control the vehicle as it is slowing down.

Given that the ABS module and sensors are electrical devices. The ABS light may illuminate as a result of a blown fuse. The electronics are protected by fuses, and a blown ABS fuse may indicate a short. A
You may find the precise position of your car’s fuse panel by consulting the owner’s manual or performing a quick Google search. Depending on where the driver’s seat is, the location may change.
Check the wiring, particularly the sections leading to the speed sensors. Use the included fuse removal tool to replace the anti-lock brake fuse if it is not damaged. Turn off the ABS light after replacing the ABS fuse. Have the car checked out by an automotive electronics mechanic if the fuse blows once more.

Hi. Just curious if anyone has experienced the mentioned problem where the ABS light remains on even after the engine has started.
After a comfortable 30-minute trip, I parked my car and left for ten minutes. Coming back to the car, the engine started more slowly than normal. (Normally, starting the engine required just one second). The battery doesn’t seem to be fully charged.
After a brief drive, my parking brake, also known as the hand brake, and the ABS light turn on simultaneously while the car is moving. I park my car, turn the key, and the parking brake returns to normal. Since then, the ABS light will not turn off. The car starts easily as usual, though.
Why is my Hyundai Sonata’s ABS light on?
The presence of an ABS indication light on your dashboard indicates that there may be a problem with your system and that you should have it checked properly. This indicator normally illuminates for one of four reasons: either the ABS module is broken, the fluid reservoir is low on fluid, the wheel speed sensors are damaged, or the system is off.
Ineffective ABS Module In fact, the traction control system in your car and the ABS have certain crucial parts in common. A device called traction control keeps all four wheels on the ground moving easily. It will cut off power from your engine until it regains steady traction if it notices that one wheel is beginning to spin erratically. This is intended to stop you from unintentionally exerting too much power, which could cause you to slip out of control. However, because your traction control and ABS share a control module and self-diagnostic system, they occasionally clash. The ABS light may illuminate in addition to the traction control light occasionally, however there are other situations when the ABS system is at fault. To pinpoint the precise problem, your car needs to be professionally diagnosed.
The fluid reservoir has low levels. Your brakes are hydraulic, which means they work by closing your brake pads and stopping your car by applying pressure from a cylinder against a fluid. This implies that the fluid level in your brake system must be steady and continuous. The volume of fluid will decrease and your brakes won’t function properly if there is a slow leak or if the fluid is allowed to evaporate out. Usually, sensors on your computer can find this, and if it does, it will turn on the ABS light.
Wheel speed sensors that are broken Wheel speed sensors are a piece of hardware that provide information to your computer about the individual speeds of the wheels. If the computer notices a deviation from these speeds, your traction control system will alter or switch power to another wheel to make up for it. However, a speed sensor can’t convey this information accurately if it becomes dusty or stops operating. It typically disables your ABS and/or traction control systems until you restart your car or the issue is fixed rather than making a ton of adjustments.
Your System Has Been Shut Down You might be surprised to learn that you can switch your traction control or ABS on and off. The indication light on your dash will often illuminate when the system is turned off to let you know that this crucial safety feature is malfunctioning. There is a good probability your system may have unintentionally turned off if only your traction control or ABS indicator is illuminated. Whether you’re unsure of where the switch is, check to see if you might have accidently bumped it. If so, refer to your owner’s manual.
Can the ABS light be reset at Autozone?
general intent Because there is a distinct processor for the ABS system, OBD II scanners like Autozone may not be able to read ABS system problems; for this reason, it displays a different light from the CEL or MIL check engine light. Thus, it is unable to read and reset the codes and lights for the ABS (or SRS) systems.
What is the time required to reset the ABS light?
Ignoring the issue and merely resetting the light will not solve it and may result in more expensive part repairs and serious auto accidents. Fault lights should not be reset until the issue has been found and fixed.
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 first positive connection.
The two terminals should be connected to one another using a battery jumper lead. Turn on the ignition and unlock the driver’s door for 20 to 25 minutes. Although the car won’t start, the light will be turned off as the electrical system’s remaining power is drained. First, reattach the terminal positive cable.
The other calls for two ports on the OBD II CONNECTOR to be jumped. To perform this properly, it is advised to use a fused bridge wire to prevent harm in the event that you unintentionally bridge the wrong ports.
Both of the aforementioned techniques should cause the lights to go out, coming back on only if the issue is still present.
How can I turn off the traction control and ABS lights?
Don’t freak out if the traction control light turns on while you’re driving but no other warning lights are on. Locate a secure location to stop, shut off your car, and then start it again. If an error in the TCS system caused the warning light to come on, it should go away when you start the engine again.
If it starts up again, you should probably call a mechanic to have the system diagnosed. Drive carefully and steer clear of abrupt acceleration that can cause the wheels to slip until it is rectified. The aforementioned advice still holds true if the ABS light also illuminates, but you should take extra care to prevent abrupt stops that could cause a skid.
You shouldn’t operate the vehicle until the issue has been resolved if the red main brake warning light, the TCS, and the ABS warning lights are all illuminated simultaneously. The result is that your entire braking system may not be able to stop your car when you need it to. Have your car towed to a shop for repairs.
To determine the trouble code that has caused the warning light to come on, a specialized scan tool is typically needed for an accurate diagnosis of TCS problems. The precise difficulty code can be used to pinpoint both the location and the component that is the fault’s cause.
How come my ABS light won’t turn off?
An issue with various parts inside or connected to the anti-lock brakes may be indicated by an ABS warning light that illuminates and remains illuminated. For instance, specialized sensors keep tabs on the wheels’ speed. The ABS warning light will remain illuminated if one or more of these wheel speed sensors are malfunctioning or broken. The same holds true if there is a wiring issue.
Other potential issues could be with the system’s hydraulic pump, solenoid valve, ABS control module, or a faulty power relay to the module. The brake master cylinder’s braking fluid level dropping or a fuse blowing can both cause the warning light to illuminate (or in the ABS reservoir if the vehicle is so equipped).
Why is my ABS light on even though I just changed my brake pads?
After having my car’s brakes fixed last week, the ABS and Traction Control lights are now on. I’m concerned that there was a problem during the service. Why are the ABS and traction control lights on now that I had my car’s brakes replaced?
In less than two minutes, find out if your auto insurance is being overcharged.
After you had your automobile serviced, if the ABS and traction control lights started to illuminate, something might have gone wrong with the brake job. Following a brake job, the following problems may cause your ABS and Traction Control light to illuminate:
- The cables for the sensor connector weren’t put back in their proper place.
- Batteries with loose terminals

When the ABS light is on, can I drive?
You can safely drive your automobile to your destination if just one of your ABS lights illuminates because your regular brakes will still function. Naturally, you will need to exercise greater caution because your ABS won’t function in an emergency. To find the cause(s) of the anti-lock brakes warning light, you should schedule an appointment for your automobile as soon as possible at your neighborhood garage.
However, if the brake warning light and the ABS light are both on at the same time, it indicates a much more serious issue, and you should not keep driving. If this occurs, you should carefully apply the brakes to bring your car to a stable stop while gradually decreasing your speed. Call your breakdown service or a nearby garage to have your vehicle recovered once you’ve stopped in a secure location and turned off your engine.
Make sure to read Dashboard Warning Lights Explained if you have other warning lights on your dashboard and would like to know what they mean.
What occurs if the ABS light remains on?
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. ABS is designed to step in by quickly “pumping” the brakes at the wheel that is locking up, allowing it to spin and preserving steering and braking control for the driver.
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.
