    Description of ESP ESP 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, ESP and TCS controls are prohibited in case of ABS failure. 2.
