RELAY STATE MONITORING

    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 engine control intervention.

    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.
