DTC C2000-00: Reader Communication Error: 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.

1. SCC detects forward vehicle with Radar sensor.
2. SCC calculates acceleration value according to distance and speed.
3. SCC transmits acceleration request to Electronic Stability Program (ESP/Electronic Stability Control (ESC) by Controller Area Network (CAN) communication.
4. When deceleration is needed, ESP (ESC) performs brake control. But when acceleration is needed, ESP (ESC) calculates engine torque request and send it to Engine Control Module (ECM) through CAN communication.
5. ECM performs acceleration control after receiving torque request.
