Typically, when your ABS light illuminates, it means your anti-lock braking system is experiencing a serious issue. Having saying that, you must always leave your ABS light on when having your brakes inspected by a professional.
To turn off the ABS light in your Toyota, take the following actions if you are certain that your brakes are in good condition:
First, open your hood and use a socket wrench to detach the negative battery cable.
The entire electrical system is reset when the battery is disconnected. If you performed the instructions above, the ABS light should turn off if it is malfunctioning. However, if your brake system is having a problem, it might start up again.

Why Won’t 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. It must be reset because it won’t go away in any case.
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 replace or loosened 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.
Using a big syringe, suction the air out of the flexible tube end of a caliper if you’re having trouble doing so and the braking fluid isn’t dripping 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 the ABS light self-reset?
Only after the ABS controller runs and passes all self-tests will the ABS light automatically reset. It is not necessary to reset it, and it generally cannot be done so.
How can I turn off the traction control and ABS lights?
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 does the ABS light continue to illuminate?
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.
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.
What happens if the ABS sensor is unplugged?
Even while some current automobiles have a button that appears to turn everything off, many of them contain complicated ABS and stability control systems that can’t be completely turned off. That can be a problem if you find yourself in a scenario where you need such systems completely destroyed. Fortunately, you can still try a ton of workarounds.
A video created by Wyatt Knox of the Team O’Neil Rally School demonstrates how you may tinker with your car to turn off such traction-aid systems. He advises disconnecting fuses connected to your stability or traction control after reading the fuse diagram for your car. The best course of action is to pull one fuse at a time while driving your automobile to assess any effects. Pulling a fuse may occasionally cause several systems to shut down, which could lead to a bad situation.
Of course, you can start unplugging sensors if the fuses don’t work. ABS and, occasionally, stability control will be disabled by removing a wheel speed sensor. You can unplug the yaw sensor in your automobile to see results. The ABS module can also be unplugged, although doing so might have a negative impact on how well your car brakes. Knox offers the following additional recommendations if none of those work:
