The car's TRC off means that the traction control system is faulty and closed. TRC, or Active Traction Control, is a common technology in modern automobiles designed to improve traction and driving stability on slippery roads. The working principle of this system is to monitor the rotational speed of the wheels and the dynamic state of the vehicle through sensors, and then control the braking force and engine output torque of each wheel based on this data to prevent the wheels from spinning and losing control.
However, when the TRC system fails, it may cause the system to not work properly, thus requiring the TRC function to be turned off. When the TRC function is turned off, the vehicle will not be able to enjoy the benefits of the traction and driving stability enhancements provided by the TRC system. As a result, with TRC off, the vehicle may be more prone to skidding and loss of control when driving on slippery roads.
So, why does the TRC system fail?TRC system failures can be caused by a variety of reasons, including sensor failures, line failures, control unit failures, and more. When the system detects a fault, in order to ensure driving safety, the TRC function will be automatically turned off, and the corresponding fault indicator will be displayed on the instrument panel. In this case, it is recommended to go to a professional car repair shop for overhaul and repair as soon as possible to solve the TRC system failure problem.
To sum up, a car's TRC off means that the traction control system is faulty and closed, which can cause the vehicle to lose traction and driving stability when driving on slippery roads. If there is a failure of the TRC system, you should go to an auto repair shop for repair and repair as soon as possible to ensure safe driving.
