HYBRID CONTROL SYSTEM OPERATION HISTORY DATA


  1. OPERATION HISTORY DATA

    Tech Tips

    The power management control ECU (HV CPU) records inappropriate operations performed by the driver and the number of abnormal conditions that have been input to the ECU as operation history data.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus: Powertrain / Hybrid Control / Data List.

    5. Enter the menu to view the number of inappropriate operations or controls that have been performed.

      Tech Tips


      • Latest Operation: Among the past occurrences, the number of inappropriate operations or controls that have been performed during the most recent 1 trip detection.

      • Latest Trip: The number of trips after the occurrence of Latest Operation.

      • Operation before Latest: The number of occurrences during the trip previous to the Latest Operation.

      • Trip before Latest: The number of trips after the occurrence of Operation before Latest.
