What does the TC slash displayed in the car mean?

The TC slash displayed in the car indicates that the traction control is turned off. The TC light is the traction control system. When the anti-lock braking system detects that some wheels are slipping, it will apply brakes to the slipping wheels to prevent the loss of traction on those wheels. Here is some related information: The traction control system can improve the vehicle's passability. When the system is working, the yellow TC indicator light on the dashboard flashes to alert the driver. The working principle of the traction control system is to replace the mechanical connection between the accelerator pedal and the throttle with an electronic throttle control device. The sensor transmits the information of the accelerator pedal to the ECU, which generates a control voltage signal based on the signal. Then, the servo motor adjusts the throttle according to the signal, thereby reducing the throttle opening and controlling wheel slip.
The TC light with a slash displayed in the car is quite important and needs explanation. TC stands for Traction Control System, and when that small slash lights up, it means the system is turned off. Normally, it acts like an invisible bodyguard, preventing wheel slippage during rainy or snowy weather. If it lights up without you manually turning it off, it might be due to accidentally pressing the TC button near the steering wheel or the sensors being covered in mud. I recommend trying to turn off the engine and restart it first. If the light remains on, you'll need to check the wheel speed sensors and wiring. Last time, my friend's car had this light on during heavy rain and almost spun out on a curve—it's really not something to take lightly. It's best to get it checked at a repair shop as soon as possible, because safety is no joke.
Don't panic when you see the TC with a slash symbol on your dashboard—it simply means the traction control function is turned off. Most vehicles have a button with a car skidding icon on the steering wheel or center console, and chances are you accidentally pressed it. Just press the button again to reactivate the system. However, if the button doesn't respond, it could indicate a faulty wheel speed sensor or fuse issue, especially common in older cars. I once helped a neighbor with a similar situation and found a loose wheel hub sensor connector. To prevent this, avoid using high-pressure water jets on wheel hubs during car washes. Be extra cautious when driving on highways with the system deactivated, as wheels are more prone to spinning on wet surfaces.
TC Slash Light On? Must be the traction control system turned off. This feature works silently in the background, monitoring wheel speed differences and automatically reducing power when slippage occurs. There are two scenarios for the slash symbol: manually deactivated is fine, but system malfunctions require attention. I recommend first checking the physical button with the skidding car icon. Some performance cars intentionally disable it for drifting, but never attempt this on public roads. Last month, an SUV with this light on ice-covered roads went sideways with just slight throttle input. If button reset doesn't work, there's an 80% chance the sensor needs replacement - parts cost around 200+, labor isn't expensive.
