CAUTION:
- If there is any problem in the CAN bus lines, an incorrect DTC may be set. Prior to this diagnosis, diagnose the CAN bus lines (Refer to CAN BUS LINE DIAGNOSTIC FLOW ).
- Whenever ECU is replaced, ensure that the CAN bus lines are normal.
- When the DTC U1415 is set in ASC-ECU, the DTC may also be set in ETACS-ECU. When the DTC is set in ETACS-ECU, carry out the diagnosis of the DTC for ETACS-ECU first.
- When the hydraulic unit (integrated with ASC-ECU) is replaced, always carry out the calibration of the steering wheel sensor, the G and yaw rate sensor and brake fluid pressure sensor (Refer to G AND YAW RATE SENSOR CALIBRATION , STEERING WHEEL SENSOR CALIBRATION and BRAKE FLUID PRESSURE SENSOR CALIBRATION ).
