FREEZE FRAME DATA
When a DTC is stored, the 4 wheel drive control ECU stores the current vehicle state as Freeze Frame Data.
Freeze Frame Data at the time a DTC is stored:
When the 4 wheel drive control ECU stores data at the time a DTC is stored, no updates will be performed until the data is cleared.
CHECK FREEZE FRAME DATA
Turn the ignition switch off.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Four Wheel Drive / Trouble Codes.
According to the display on the GTS, select the trouble code data display with Freeze Frame Data.
