The Toyota Highlander is a versatile and reliable vehicle, equipped with advanced features to enhance driving safety and performance. One such feature is the Traction Control (TRAC) system, designed to improve vehicle stability and control, particularly on slippery or uneven surfaces. However, there may be instances where the TRAC system is deactivated, either intentionally or unintentionally. If you’re wondering how to turn the TRAC back on your Toyota Highlander, this article is for you. We’ll delve into the details of the TRAC system, explore the reasons behind its deactivation, and provide a step-by-step guide on how to reactivate it.
Understanding the TRAC System
The TRAC system is an electronic stability control feature that helps the vehicle maintain traction and stability by controlling the engine power and applying the brakes to individual wheels. This system is particularly useful in situations where the vehicle is accelerating or cornering, and the wheels start to slip or lose traction. The TRAC system works in conjunction with other safety features, such as the Anti-lock Braking System (ABS) and the Electronic Stability Control (ESC) system, to provide a safe and stable driving experience.
Why is the TRAC System Important?
The TRAC system is a critical safety feature that can help prevent accidents and reduce the risk of skidding or losing control of the vehicle. By controlling the engine power and applying the brakes to individual wheels, the TRAC system can help the vehicle stay on course and maintain traction, even in challenging driving conditions. Additionally, the TRAC system can help improve vehicle stability and control, particularly when driving on slippery or uneven surfaces.
Benefits of the TRAC System
The TRAC system offers several benefits, including:
Improved vehicle stability and control
Enhanced safety features, including reduced risk of skidding or losing control
Better performance in challenging driving conditions, such as snow, ice, or rain

What is TRAC and how does it work in my Toyota Highlander?
TRAC, which stands for Traction Control, is a system designed to improve the stability and control of your vehicle, particularly in low-traction driving conditions such as snow, ice, or sandy roads. It works by monitoring the speed and traction of each wheel and automatically applying the brakes to any wheel that starts to slip or lose traction. This helps to transfer power to the wheels that still have traction, allowing your vehicle to maintain stability and stay on course.
The TRAC system in your Toyota Highlander is integrated with the vehicle’s electronic control systems and uses a combination of sensors and computer controls to monitor and adjust the traction of each wheel. When the system detects wheel slip, it can apply the brakes to the slipping wheel and reduce engine power to help the vehicle regain traction. The TRAC system can be especially useful in situations where you need to accelerate or brake suddenly, such as when merging onto a highway or stopping at an intersection. By helping to maintain traction and stability, the TRAC system can help to improve the overall safety and performance of your vehicle.
Why would I need to reactivate TRAC on my Toyota Highlander?
There are several reasons why you might need to reactivate TRAC on your Toyota Highlander. One common reason is that the system may have been disabled due to a problem with one of the system’s sensors or components. For example, if one of the wheel speed sensors is faulty, the TRAC system may not be able to function properly, and you may need to have the sensor replaced before you can reactivate the system. Another reason you might need to reactivate TRAC is if you have recently installed new tires or wheels on your vehicle, as this can affect the system’s calibration and require it to be reset.
In some cases, you may need to reactivate TRAC because the system has been intentionally disabled. For example, if you are driving in deep snow or sand, you may need to turn off the TRAC system to allow your vehicle to gain traction and momentum. However, once you are back on a paved road, you should reactivate the TRAC system to help maintain stability and control. Regardless of the reason, reactivating TRAC is a relatively simple process that can usually be done using the vehicle’s onboard computer system or by following a series of steps outlined in the owner’s manual.
How do I know if TRAC is deactivated on my Toyota Highlander?
If the TRAC system is deactivated on your Toyota Highlander, you may notice a warning light on the dashboard indicating that the system is not functioning. The light may be accompanied by a message or alert, such as “TRAC Off” or “Traction Control Disabled.” You may also notice that your vehicle is more prone to wheelspin or loss of traction, particularly in low-traction driving conditions. In some cases, the vehicle may even enter a “reduced power” mode, where the engine power is limited to help prevent wheelspin and loss of control.
If you suspect that the TRAC system is deactivated on your Toyota Highlander, you should consult the owner’s manual or contact a Toyota dealership or certified mechanic for assistance. They can help you diagnose the problem and determine the best course of action to reactivate the TRAC system. In some cases, the system may simply need to be reset or recalibrated, while in other cases, repairs or replacement of faulty components may be necessary. Regardless of the cause, it is important to address the issue as soon as possible to help ensure the safety and performance of your vehicle.
Can I reactivate TRAC on my Toyota Highlander myself?
Yes, in many cases, you can reactivate TRAC on your Toyota Highlander yourself using the vehicle’s onboard computer system or by following a series of steps outlined in the owner’s manual. The process typically involves using the vehicle’s menu system to select the TRAC option and then following the prompts to reactivate the system. You may also need to perform a series of tests or checks to ensure that the system is functioning properly. It is recommended that you consult the owner’s manual or contact a Toyota dealership or certified mechanic if you are unsure about how to reactivate the TRAC system.
However, if the TRAC system has been deactivated due to a problem with one of the system’s sensors or components, you may need to have the issue repaired by a qualified mechanic before you can reactivate the system. In this case, it is recommended that you contact a Toyota dealership or certified mechanic for assistance, as they will have the necessary expertise and equipment to diagnose and repair the problem. Additionally, if you are not comfortable with the process of reactivating the TRAC system yourself, it is always best to seek the advice of a professional to ensure that the system is functioning properly and safely.
