DTC C1702-55: Variant Coding Error: General Description
2020 Kia Soul LX, Standard TransSECTION General Description
Smart Cruise Control (SCC) has additional function which helps to keep safety distance from the car ahead as compared with conventional cruise control. Control step is as follows.
- SCC detects forward vehicle with radar sensor.
- SCC calculates acceleration value according to distance and speed.
- SCC transmits acceleration request to Hydraulic Electronic Control Unit (HECU) by CAN communication.
- When deceleration is needed, HECU performs brake control. But when acceleration is needed, HECU calculates engine torque request and send it to Engine Management System (EMS) by CAN communication.
- EMS performs acceleration control after receiving torque request.
