What does the TC slash yellow light on the dashboard mean?
1 Answers
The TC slash yellow light on the dashboard may illuminate if the traction control switch near the gear shift lever is accidentally pressed, turning off the traction control system. If accidental activation is ruled out, it indicates a malfunction in the traction control system. The traction control system ensures that the vehicle maintains optimal traction under various driving conditions. A malfunction in this system is not a minor issue and requires prompt repair. Possible causes of traction control system failure include: 1. Solenoid valve malfunction; 2. Dirty engine oil clogging the solenoid valve filter screen; 3. Wear on the actuator gear and impeller causing oil pressure leakage and triggering the warning; 4. Dirty throttle body with an opening reaching 20%, leading the engine computer to falsely diagnose a TC fault.
