What does trcoff mean?

[VanJosie]

trcoff stands for Traction Control Off. The function of the traction control system is to improve the vehicle's passability. When ABS detects that the wheels are slipping, the traction control system will apply brakes to the slipping wheels, thereby preventing the loss of traction on those wheels. 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 ECU receives the accelerator pedal information transmitted by the sensors and then generates a control voltage signal based on the signal. The motor then adjusts the throttle according to the voltage signal, thereby reducing the throttle opening and controlling wheel slip.
