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.
How can you turn a Toyota Rav4’s ABS light back on?
Moving thread to 4.3 Mechanical Adapted from a sticky thread there about the ABS codes:
Even unplugging the battery will not erase any ABS/VSC codes or lights. By connecting a jumper wire to pins 4 and 13 of the diagnostic port, you can erase these codes from the Skid Control ECU. Immediately after turning on the ignition, press the brake pedal eight or more times. The brake lights must flash eight times in less than five seconds by lightly pressing the brake pedal. The lights and codes ought to disappear after turning off the key and taking out the jumper.
Why is the ABS light on on my vehicle?
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.
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
- 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.
AutoZone is able to reset ABS codes.
Unfortunately, reading your car’s codes is the only way to determine whether the ABS is the cause of the issue. As part of our Fix Finder service, AutoZone can scan your codes, or if you already have a scan tool, you can do it yourself.
Can a low battery cause ABS light to come on?
Our technicians advise checking the battery first if the ABS light on the instrument panel illuminates. 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.
Driving with the ABS light on is it safe?
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.
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.
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.
Oreillys, can you examine the ABS light?
The ability to read and clear DTCs and ABS codes, view oil life, check brake pad life, and determine hybrid cell voltage are just a few of the features and capabilities that are accessible, depending on the tool.
