DTC C1702-04: Variant Coding Error: General Description

This Electronic Stability Control (ESC) system recognizes a critical driving condition by yaw-rate sensor, lateral acceleration sensor and Steering Angle Sensor (SAS). And then it stabilizes the vehicle by a individual wheel braking and motor torque control through CAN communication. There is no difference in the HECU's hardware side according to a vehicle specification, but there is a difference in its software side because the applied vehicle parameters differ according to a vehicle specification. The HECU stores the variant code value in the ECU's memory based on the received data by CAN communication.
