Tech Tips
-
The brake actuator assembly (VSC ECU) stores spiral cable sub-assembly (steering angle sensor) and yaw rate sensor DTCs and performs DTC communication by receiving information from the spiral cable sub-assembly (steering angle sensor) and yaw rate sensor.
-
The ECM uses the CAN communication system to perform DTC communication instead of the conventional communication line (SIL).
