CHECK FREEZE FRAME DATA (READ BY GTS)
Tech Tips
The ECU data indicating the vehicle status is stored in the ECU as a freeze frame data simultaneously as the DTC is stored.
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Radar Cruise / Trouble Codes.
From the DTC screen, select the DTC (snow icon displayed) to which freeze frame data is recorded.
Note
The vehicle condition when the DTC was detected is stored as the freeze frame data. Also, the driving support ECU can store up to 3 DTCs.
