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 power switch on (IG) and turn the Techstream on.
3. Select the following menu items: Powertrain / Hybrid Control / Data List.
4. Select the menu to view the number of special operations or controls that have been effected.

   HINT: 

   • Latest Operation: Among the past occurrences, the number of special operations or controls that have been effected 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".
