How to solve the problem of tc light in Buick LaCrosse dashboard

The tc light of Buick LaCrosse indicates traction failure. You can press the button under the gear shifting mechanism. If the tc light cannot be cancelled, go to the 4s shop to find a professional maintenance master to solve it.

When the tc light is on, the engine control unit instructs the throttle actuator control system to work in the "reduced engine power" mode, so that the traction control system off indicator light is on (c0240).

Extended data:

Is TC light a traction control system? When ABS anti-lock braking system detects that some wheels are slipping, it will brake the slipping wheels to prevent them from losing traction.

This is the traction control system, which can improve the passability of vehicles? When the system is working, the yellow "TC" indicator on the instrument flashes to give the driver a hint.

The working principle of traction control system is to replace the mechanical connection between accelerator pedal and accelerator with electronic accelerator device. The sensor transmits the information of the accelerator pedal to the ECU, and the ECU generates a control voltage signal according to the signal, and the servo motor adjusts the accelerator according to the signal, so as to reduce the accelerator opening and control the tire skid.
