caution |
- If there is any
problem in the CAN bus lines, an incorrect diagnosis code may be set. Prior to this diagnosis,
diagnose the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table
).
- If diagnosis code U1073 is set in ASTC-ECU, always diagnose the CAN bus line. If
there is any fault in the CAN bus lines, an incorrect diagnosis code may be set. In this case,
the set diagnosis code is not highly reliable.
- Whenever ECU is replaced, ensure that the CAN bus lines are normal.
- When the hydraulic unit (integrated with ASTC-ECU) is replaced, always carry out
the calibration of the steering wheel sensor and the G and yaw rate sensor (Refer to
).
