The Electronic Stability Program (ESP) system recognizes a critical driving condition with the Yaw-rate sensor, Lateral acceleration sensor and Steering angle sensor. The ESP stabilizes the vehicle by a individual wheel braking and engine torque control through CAN communication.
The HECU checks variant code and if an inappropriate variant code or no variant code is detected, this DTC is set.
