HYBRID CONTROL SYSTEM OPERATION HISTORY DATA

  1. OPERATION HISTORY DATA

    Tip:

    The hybrid vehicle control ECU 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 GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS 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.

      Tip:

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

      • 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.
