C1702 Variant Coding Error - General Information

Component Location





General Description

The ESC system is the shorten word of Electronic Stability Control system. This system recognizes a critical driving condition by Yaw-rate sensor, Lateral acceleration sensor and Steering angle sensor. And then it stabilizes the vehicle by a individual wheel braking and engine torque control through CAN communication. There is no difference in the HECU's hardware side according to a vehicle speficiation, 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.

DTC Description

The HECU checks variant code and if an inappropriate variant code or no variant code is detected, this DTC is set.
