Reasons for the TC light on the Buick GL8 dashboard: 1. Faulty solenoid valve; 2. Dirty engine oil, clogged solenoid valve filter screen; 3. Wear of actuator gears and impellers leading to oil pressure leakage and triggering an alarm; 4. Dirty throttle. TC refers to the Traction Control System, which ensures optimal traction under various driving conditions. The Buick GL8 has a body length, width, and height of 5238mm, 1878mm, and 1776mm respectively, with a wheelbase of 3088mm. The vehicle is equipped with a high-performance ADM small module unit system, featuring 18 independent high-beam lighting zones and offering 8 lighting modes, including ADB anti-glare high beams, to ensure nighttime driving safety with intelligent technology.
