DTC C1702: Variant Coding Error: General Description

SCC (Smart Cruise Control) has additional function which helps to keep safety distance from the car ahead as compared with conventional CC (Cruise Control). Control step is as follows.

1. Radar sensor measures distance from the car ahead and relative speed (Radar Sensor)
2. SCC calculates acceleration/deceleration value for keeping relevant distance from the car ahead according to speed and transmits this value to ESC system.
3. ESC performs engine torque and brake control after calculating torque for making received acceleration/deceleration value.
