What does the TC light with a slash mean in the Envision?
1 Answers
The yellow TC light with a slash in the Envision is the Traction Control System indicator. Press the button below the gear shift mechanism, then turn off the ignition and restart to reset the system, and the yellow TC light with a slash will turn off. If the warning light remains on or lights up again while driving, repairs are needed. Possible causes for the TC light to illuminate include: solenoid valve failure; dirty oil clogging the solenoid valve filter; wear on the actuator gear and impeller, leading to oil pressure leakage and triggering the alarm; dirty throttle with an opening reaching 20%; or the engine computer misjudging a TC fault. The working principle of the Traction Control System involves replacing the mechanical connection between the accelerator pedal and the throttle with an electronic throttle device. Sensors transmit the accelerator pedal's information to the ECU, which then generates a control voltage signal based on this information. The motor adjusts the throttle according to the signal, thereby reducing the throttle opening and controlling wheel slip. For drivers operating vehicles in rainy or snowy conditions, this can help reduce occurrences of wheel slip or loss of control.
