Code No. U1417: Implausible coding data: Notes

CAUTION:
  • If diagnostic trouble code U1417 is set in KOS-ECU, always diagnose the CAN bus lines. If there is any fault in the CAN bus lines, an incorrect diagnostic trouble code may be set. In this case, the set diagnostic trouble code is not highly reliable.
  • Before replacing the ECU, ensure that the communication circuit is normal.
  • When the diagnostic trouble code U1417 is set in KOS-ECU, the diagnostic trouble code may also be set in ETACS-ECU. When the diagnostic trouble code is set in ETACS-ECU, carry out the diagnosis of the diagnostic trouble code for ETACS-ECU first.
