You’re all set to embark on your next vacation and head into the mountains, but you’re unsure if your car is prepared to travel safely on icy or snowy roads. Thankfully, Toyota provides a number of safety systems including Traction Control that help out when required.
But what does traction control actually do? Traction Control assists when wheel slippage is detected, enabling you to accelerate safely and effectively in slick circumstances. This technology is standard in Toyota’s Star Safety System, and some 4-wheel-drive Toyota vehicles offer “A-TRAC or Active Traction Control.”

How does TRAC work?
The TRAC system in your car constantly monitors the tires, and when they start to slide, it gives you the extra traction and grip you need to accelerate effectively and safely on slick or wet roads. In order to keep the tires in touch with the pavement, the system either applies the brakes or slows down the engine. Except for the Yaris iA, all Toyota automobiles come equipped with this feature as standard.
What is A-TRAC?
You obviously adore Toyotas and off-roading, so why not put your all-wheel drive to use the way it was intended? A-TRAC is short for “Some Toyota 4-wheel-drive models come standard with active traction control.
A-TRAC detects when one or more wheels have lost traction and automatically applies the brakes to the wheel with no traction, allowing it to send power to the wheel with traction. While you have to manually turn this feature on and off, once it is on, it automatically detects wheel spin and distributes torque between front and rear wheels to suppress unnecessary wheel spin and control skidding.
You must first put your car in neutral, shift into 4LO, and then push the A-TRAC button “A-TRAC key.
What happens when A-TRAC is off?
There’s a good chance that you’ve either driven a car that struggled to accelerate from a stop or witnessed a one that did. A-TRAC was created with off-roading in mind and is essentially a more robust version of the conventional traction control system. Your car might have a tougher difficulty responding to off-road conditions while A-TRAC is off, and you’ll probably suffer more wheel spin than when A-TRAC is engaged.
What vehicles come equipped with A-TRAC?
Although not all Toyota 4-wheel-drive models come with the A-TRAC technology, some do. If you enjoy being outside, off-roading, and getting your Toyota dirty, you might want to consider buying a car with A-TRAC.
What does Toyota 4Runner mean by TRAC OFF?
Traction control is disabled, according to the “TRAC OFF Indicator.” To avoid wheelspin and additional downshifting, the traction control is turned on and off by the TRAC system. Press and release the button fast to turn off the TRAC system. The TRAC OFF signal should activate. To restart the system, press the switch once again.
How does the A-TRAC button function?
A-TRAC can direct power to the wheel with traction by automatically applying the brakes to the wheel that has lost traction when one or more wheels have done so.
Should I turn on or off TRAC?
Keep in mind that traction control is never turned off. The light may turn on when it is turned off, however this varies from car to automobile. If you haven’t touched anything or have only momentarily lost traction, it’s most likely only that you shifted your sensors.
Why are my TRAC off and check engine lights on?
I’m here. The traction control is indicated by the Trac Off light. For different reasons, the computer has disabled the traction control. It’s possible that the controller, the speed sensor for the car, or the wheel speed sensors aren’t working properly. Check the computer’s stored codes when the engine light is on to get a head start on figuring out why your traction control isn’t working. If you require additional help with the Trac Off light and the engine light being on, then get in touch with a specialist, like one from Your Mechanic.
C1201:
The two P0 codes indicate that the emissions system has a leak. Technically, it might be in the charcoal canister or filler neck, but most of the time it’s just a leaky gas cap. Either a worn-out cap or one that was put incorrectly.
The car is instructed to switch on the check engine light and turn off the traction and VSC by the C1201 code. In essence, this code is responsible for alerting you to an issue when the other two appear. Since they are the ones that created it, fixing the other codes should also repair this one.
Does four-wheel drive traction control function?
The car’s AWD and 4WD systems aid in forward motion, but traction control can also enhance stopping and handling. The mechanism engages the brakes and decreases the power to maintain grip when wheel slide is detected. This is so effective that according to the National Highway Traffic Safety Administration, traction and stability control systems can avert 35 percent of collisions.
Additionally, traction control can enhance 4WD and AWD. In hill descent systems, low-speed transfer cases are replaced by braking, and torque vectoring enhances handling by adjusting the amount of power sent to each wheel as the car is driven around turns.
Why did my check engine and traction control lights turn on, Toyota?
A system bulb check is initiated as the ignition key rotates through the phases of Off, Run, and Start. As the car starts and runs, the traction control system light should come on for one to two seconds before going out. If the indicator continues to illuminate, either the traction control system is malfunctioning or the system has been disengaged.
Can I drive without using the traction control?
It is safe to disable traction control on dry, clean pavement. Disabling this function will also make it easier to turn in high-speed corners.
Only when driving on slick roads is it dangerous to turn off your traction control. If you travel at a fast pace, having it off could create slippage, which could be dangerous. It is preferable to leave TCS on if you reside in an area with variable weather.
How can you get the Toyota’s Trac Off light back on?
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.

The Trac Off button cannot be found.
To switch off your TRAC, just push and hold the VSC Off button next to your gear shift. Near your speedometer, look for the TRAC OFF indication light. You will also find your VSC Off indication light here. Simply press the button once more to turn the TRAC back on.
What could activate the VSC light?
There are numerous things that can go wrong because the VSC system is connected with the engine control and the brake control systems to control your car’s traction.
A bad accelerator pedal, faulty throttle body, faulty ABS sensors, or a faulty mass airflow sensor are the most typical reasons of a VSC light.
The quickest way to determine what set off your VSC light is to use a diagnostic scanner to read the issue code memory.
Why would you want the traction control turned off?
when attempting to get out of snow or mud, or when climbing a steep, icy hill. Reduced power may cause the vehicle to become stuck when trying to move through deep snow or mud. It makes no sense to reduce power or apply brakes to a spinning wheel(s) in these situations.
What occurs if traction control is disabled?
The traction control system of a vehicle is designed to help drivers retain vehicle stability and control when driving in poor weather or when coming to a sudden stop.
Each wheel has electronic sensors that communicate data to the Powertrain Control Module (PCM) about each wheel’s traction and stability. The traction control system will then dial down the engine’s power and apply the brakes to any potential slipping wheels. By doing this, power can be transferred from the sliding wheel or wheels to the non-slipping wheel or wheels. This gives drivers the capacity to keep the car under control. Even when the traction control system is activated, drivers must exercise caution when driving in poor weather conditions and when coming to a stop.
The driver won’t have access to the safety measures provided by the traction control system if it is disengaged. Only when/if the car gets stuck in mud, snow, or ice would it be necessary to turn off the TCS. It could be challenging to free the car if the TCS is activated while it is stuck in mud, snow, or ice. Turning the vehicle off and back on should also turn the traction control system back on because the TCS activates automatically when the vehicle is turned on.
Contact a qualified technician who can conduct a traction control system inspection if you think there might be a problem with your traction control system (TCS).
Will traction control slow me down?
In fact, traction control slows you down rather than speeds you up during acceleration. Some individuals mistakenly believe that the additional traction allows you to floor it. They presumptively believe the traction control can keep your wheels on the ground.
The exact opposite is true. If you feel the need for speed, disable traction control. In order to limit the amount of power going to the wheels, the traction control limits acceleration.
This offers you the extra traction and prevents the wheels from spinning out, but it won’t make you move more quickly.
Is It Better To Launch With Traction Control On Or Off?
Launching with the traction control engaged is beneficial if you’re on slick roads, battling ice and snow.
However, launch control, if available on your vehicle, is more effective if the roads are dry and you’re aiming for maximum speed.
By lowering some of the engine torque, traction control functions. As a result, power is restricted, slowing acceleration slightly.
Additionally, it exerts some force on the drive wheels, allowing you to maintain control of them as you (slowly) maximize the car’s traction on the road.
This is OK, especially in conditions like ice and snow where you want more traction and less power. However, launch control should be used if the objective is to launch quickly and forcefully rather than to enhance traction.
By doing this, you precisely let the car’s computer know that you want a quick acceleration at takeoff.
Does Traction Control Limit Power?
Technically speaking, electronic traction control operates by first decreasing speed and subsequently engine power in current automobiles.
Sensors are used in this system to measure how quickly each wheel is spinning. When one wheel spins more quickly than the others, traction has been lost.
After that, brakes are applied to that wheel to slow it down and prevent additional slippage. This braking should allow the wheel to regain traction.
The majority of the time, this is sufficient to address the issue, and for many cars, this is all that traction control systems accomplish.
The next stage with some vehicles, though, is to reduce engine power going to the wheels. If your car is one of them, you might be able to feel when the power is stopped by the traction control.
Similar to how anti-lock brakes feel when they’re engaged, the gas pedal seems unsteady and pulsing.
