POWER INTEGRATION SYSTEM OPERATION HISTORY LIST

Note


  • The History of Reason for Operation is stored in the main body ECU (multiplex network body ECU). Because the stored fuse shut off history is cleared when the cable is disconnected from the battery terminal, do not perform work involving disconnecting the cable from the battery terminal until the end of checking and recording.

  • During inspection at the workshop, if you perform an operation before saving the fuse shut off history, the existing fuse shut off history may be cleared.

  • With the "Read Fuse Shut Off History" function, the fuse shut off history time is calculated from the "Current time in the GTS" and "Time counter in the control ECU". Therefore, accurately adjust the current time in the GTS before reading the fuse shut off history.
