As a Toyota Highlander owner, you might have encountered a situation where your vehicle’s dashboard display shows “TRAC OFF.” This can be confusing, especially if you’re not familiar with the terminology or the reasons behind this message. In this article, we will delve into the world of Toyota’s traction control system, exploring what TRAC OFF means, the reasons it appears, and how to resolve the issue.
Introduction to TRAC and VSC
The TRAC OFF message is related to Toyota’s Traction Control (TRAC) system and Vehicle Stability Control (VSC) system. Both systems are designed to improve the vehicle’s stability and traction, particularly during slippery or uneven road conditions. The TRAC system helps to prevent the wheels from slipping by reducing engine power, while the VSC system assists with stabilizing the vehicle by controlling the engine power and applying the brakes to individual wheels if necessary.
How TRAC and VSC Work
To understand why your Toyota Highlander might say TRAC OFF, it’s essential to know how these systems work. The TRAC system uses sensors to monitor the speed and traction of each wheel. If the system detects that a wheel is losing traction, it can reduce engine power to that wheel to prevent it from slipping further. The VSC system, on the other hand, uses a combination of sensors, including those that monitor the vehicle’s steering angle, yaw rate, and lateral acceleration. This allows the VSC to make adjustments as needed to keep the vehicle stable and on course.
Activating and Deactivating TRAC and VSC
Both the TRAC and VSC systems are typically activated automatically when the vehicle is started. However, drivers can manually deactivate these systems by pressing a button, usually located on the dashboard or center console. Deactivating these systems can be beneficial in certain situations, such as when driving in deep snow or mud, where the systems might interfere with the vehicle’s ability to gain traction.
