What does the ESC maintenance light on a Buick car mean?
1 Answers
Buick car showing ESC maintenance indicates a malfunction in the vehicle's Electronic Stability Control system, which may lead to accidents during turns or on rough roads. The ESC system consists of: 1. Steering sensor; 2. Wheel speed sensor; 3. Yaw rate sensor; 4. Lateral acceleration sensor. The function of ESC is: When the vehicle experiences understeer causing outward skidding or oversteer causing the vehicle to cross the centerline or even spin during quick turns, evasive maneuvers, or avoiding suddenly appearing cars or animals, the system uses computer-controlled engine output and individual wheel braking to eliminate understeer or oversteer, thereby improving driving dynamic stability.
