Buick car TC light on indicates a malfunction in the traction control system. If the owner accidentally turns off the traction control switch next to the gear shift lever, the indicator light will also illuminate. Introduction to TC: 1. TC stands for Traction Control System in English. 2. The role of TC is to enable the car to obtain the best traction under various driving conditions. The reasons for the traction control system light coming on are usually the following: 1. Solenoid valve failure. 2. Dirty engine oil clogging the solenoid valve filter. 3. Wear of the actuator gear and impeller leading to oil pressure leakage and triggering an alarm. 4. Dirty throttle, opening degree reaching 20%, causing the engine computer to mistakenly judge a traction control system failure.
