HINT:
- The master cylinder solenoid (skid control ECU) 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 uses the CAN communication system to perform DTC communication instead of the conventional communication line (SIL).
