CAN Communication System

SYSTEM DIAGRAM

System Diagram:






HINT:
- The skid control ECU detects and stores steering sensor and yaw rate sensor DTCs and performs DTC communication by receiving information from the steering sensor and yaw rate sensor.
- The ECM detects and stores distance control ECU DTCs, and performs DTC communication by receiving information from the distance control ECU.
- The ECM uses the CAN communication system to perform DTC communication instead of the conventional communication line (SIL).
