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.

How can a Toyota ABS code be cleared?
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.

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.
What does ABS on a Toyota Rav4 stand for?
While braking, accelerating, or turning on a slick surface, the anti-lock braking (ABS) system is employed to maintain wheel motion and traction. The traction control system (TCS) and this system share the same parts, and the ABS control module integrates the functionality of both systems.
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 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.
Can I drive my car with the ABS light on?
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.

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.
