FREEZE FRAME DATA
Tech Tips
The EV control ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored. It can be used for estimating or duplicating the vehicle conditions that were present when the malfunction occurred. To confirm the details of the hybrid control system, check the detailed information for the DTC information code in the Data List (INF code).
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / EV / Trouble Codes.
Select a DTC in order to display its freeze frame data.
Check the freeze frame information recorded with the DTC.
Tech Tips
For detailed information and specified values for each item, refer to the corresponding items in the Data List / Active Test.
If DTCs of the FC boost control system and FC control system are found, record the corresponding freeze frame data as well.
