CAUTION:
  • If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be set. Prior to this diagnosis, diagnose the CAN bus lines.
  • Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
  • When the hydraulic unit (integrated with ASC-ECU) is replaced, after turning the ignition switch ON and OFF (vehicle information from ETACS-ECU is registered), 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  .)
  • When the ASC-ECU connector or battery terminal is disconnected with the ignition switch ON, this diagnostic trouble code may be set.
  • When this diagnostic trouble code is set, no other failure information will be set.
