OPERATION HISTORY DATA

HINT:
The HV control ECU records the special 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 ignition switch to the ON position and turn the intelligent tester on.

  3. Select the following menu items: Powertrain / Hybrid Control / DTC.

  4. Select the menu to view the number of special operations or controls that have been effected.

    HINT:
    1. LATEST OPER: Among the past occurrences, the number of special operations or controls that have been effected during the most recent 1 trip detection.
    2. LATEST TRIP: The number of trips after the occurrence of LATEST OPER.
    3. BEF LATST OPER: The number of occurrences 1 previously from the LATEST OPER.
    4. BEF LATST TRIP: The number of trips after the occurrence of BEF LATST OPER.
