• Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
• When the hydraulic unit (integrated with ASC-ECU) is replaced, always perform the calibration of steering wheel sensor, G and yaw rate sensor, brake fluid pressure sensor, cut valve, and inlet valve. (Refer to G AND YAW RATE SENSOR CALIBRATION  , STEERING WHEEL SENSOR CALIBRATION  , MASTER CYLINDER BRAKE FLUID PRESSURE SENSOR CALIBRATION  , and CALIBRATION OF CUT VALVE AND INLET VALVE  .)
