Description and Operation

Description of ESC Electronic Stability Control (ESC) recognizes critical driving conditions, such as panic reactions in dangerous situations, and stabilizes the vehicle by wheel-individual braking and ...

Troubleshooting

Failure Diagnosis 1. In principle, ESC and TCS controls are prohibited in case of ABS failure. 2. When ESC or TCS fails, only the failed system control is prohibited. 3. However, when the solenoid valve ...
