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 are the traction control and ABS brake lights on my Prius?
ABS isn’t working: ABS (anti-lock braking system) and traction control frequently share a control module and an internal self-diagnostics system. As a result, the traction control light may occasionally come on if there is a problem with the ABS. Both the Traction Control and ABS lights will be on if this is the situation.
Broken wheel speed sensors: Wheel speed sensors measure how fast each wheel is moving and are often found in the wheel bearing assembly. The traction control module decides whether or not to shift power based on the information the sensors pass along. Wheel speed sensors may get clogged or damaged and cease to function, making it impossible for the traction control module to determine when to turn on the system.
Faulty traction control module: The traction control module, which is once again frequently shared with the ABS, may malfunction or completely fail, rendering the system inoperable.
What does the Prius’ red triangle mean?
Regular maintenance should be second nature for all car owners, especially since the majority of new automobiles alert us when an oil change is necessary or our tire pressure is low. The “red triangle of doom” on a Toyota Prius, however, resembles the check engine light on conventional combustion engines.
The warning light may just indicate low oil pressure, or it may indicate something more. Your initial course of action should be to have the codes scanned and diagnosed in case your hybrid car is dealing with a more serious problem.
Common Causes
Many Prius drivers have stated the most common cause for a red triangle of death light is an issue with their battery. P0A80 and P3000 are frequently the codes that appear following a diagnostic.
The battery control system of the Prius is identified by the P300 code. This code indicates a fault with the HV battery’s ECU, albeit the reason of the issue is generally complicated. Your Prius may exhibit any of the following symptoms:
What triggers the ABS light to turn on and remain on?
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. In fact, the traction control system in your car and the ABS have certain crucial parts in common.
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 the ignition on for 20 to 25 minutes while opening the driver’s door. 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. It is advised to use a fused bridge wire for safety so as 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.

Will the ABS light turn off by itself?
Every time you start the engine, your ABS system does a self-check. The ABS light should begin to blink on the dashboard as soon as you start the engine. This is typical and demonstrates that the ABS system is doing the necessary self-checks.
Again, it’s totally normal for the ABS Warning Light to flash on and off in this manner, and depending on your car, it typically lasts for 2-4 seconds. We have a problem when the ABS light is illuminated for a prolonged period of time.
Depending on the vehicle you drive, you might also encounter:
- If your ABS system is turned off or disengaged, you should still be able to use the standard brake controls.
- The brake pedal is pulsing as a result of your ABS system turning on and off.
- a clanging sound came from the ABS test. Your ABS system’s engagement and disengagement can be audible in this sound.
How can the traction control light on a Toyota be reset?
Vehicle Stability Control, or VSC as it is commonly known, is the stability control system used in Toyota automobiles. By lowering or eliminating the power provided to your wheels, stability control aids in the maintenance of traction and control in your vehicle. By automatically providing brake pressure to up to three wheels, it achieves this. The system’s main objective is to keep your car traveling in the direction of its wheels. Since 2012, at least in the USA, it has become a necessary safety requirement. Naturally, VSC OFF denotes that your Toyota’s stability control is turned off.
VSC Light Easy Fix
Depending on the model year of the Toyota, a button with the same icon as the light in your gauges will be located either next to your shifter or next to your steering wheel. When you’ve found it:
- Ensure that you have come to a complete stop. If you can, put the car in park.
- For a few seconds, hold down the VSC button.
- The indicator lights for TRAC OFF and VSC OFF will turn on. Now both systems are off.
- Once more, press the VSC button. As soon as both lights go out, the systems are back in operation.
If the VSC OFF light is still on, there can be a glitch in your car’s computer or a problem with the VSC system. Bring your car to a Toyota service location near you so a qualified technician can check the codes and identify the problem. Although it is safe to drive your Toyota even with the VSC OFF light on, we advise caution, especially in bad weather.

How can I disable 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.
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.
Can ABS issues be brought on by a poor 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.
What should you do if the ABS light illuminates?
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.
