Operation History Data

HINT: 

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 Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream 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.

   HINT: 

   • Last Operation: Among the past occurrences, the number of inappropriate operations or controls that have been performed during the most recent 1 trip detection.
   • Last Trip: The number of trips after the occurrence of Last Operation.
   • Operation before Last: The number of occurrences during the trip previous to the Last Operation.
   • Trip before Last: The number of trips after the occurrence of Operation before Last.
