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.
Main cause of this code is a problem related to ESC. In case that ESC can not perform torque control due to having a problem, ESC sends a message which represents torque control disable to SCC. SCC monitors torque control disable message from ESC with every reception of the CAN message. SCC sets this code when it recognizes torque control disable message being true.
? The DTC of C1202, C1205, C1208, C1211, C1283 may occur with C1360 simultaneously.
