Mazda 8's dashboard shows that tcs off car can't start.

TCS is called traction control system or traction control system in Chinese ... When a vehicle runs on a smooth road surface, such as a slippery asphalt road surface, the front wheels will slip when accelerating, and wheel slip will lead to the reduction of vehicle acceleration ability or steering failure, which will affect the driving stability of the vehicle. Therefore, when the driving wheel slips, the TCS control system will reduce the torque of the engine through the ABS/VDC control system, and change the shift time by communicating with the automatic transmission control module when necessary, thus reducing the wheel slip, improving the driving acceleration performance of the vehicle, eliminating the wheel steering failure and improving the driving stability of the vehicle. ABS/VDC system detects whether the driving wheel slips by comparing the wheel speed signals of four wheels, controls the power of the engine by closing the electronic throttle (ETC) or cutting off fuel injection, or reduces the slip by applying braking force to the front wheels. Turn the vehicle to the right route.

Simply put, the traction control of automobile is to reduce the engine power by reducing the throttle opening, or to achieve the goal by braking control and wheel slip. The car equipped with TCS works by combining these two ways, that is, ABS/TCS.

Warning: TCS system is designed to prevent wheel slip, but when driving at high speed, it is impossible to avoid the car slip caused by sudden steering or other dangerous operations. Therefore, in order to ensure safety, please be especially careful when driving on a flat road.

Therefore, TCS is always on.

If TCS is turned on, will there be an indicator light? This question is actually very simple. If the light is on, it means that the TCS system is out of order ... See the instructions.
