CHECK FREEZE FRAME DATA
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 engine switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Radar Cruise 1*1 or Radar Cruise 2*2 / Trouble Codes.
*1: Output from the ECM
*2: Output from the driving support ECU Assembly
From the DTC screen, select the DTC (snow icon displayed) to which freeze frame data is recorded.
