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.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the mode control actuator connector. 3. Verify that the mode control actuator operates to the defrost mode when connecting 12V to terminal 3 and grounding terminal 7.
