CHECK FREEZE FRAME DATA
The ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored.
Enter the following menus: Powertrain / Radar Cruise1*1 or Radar Cruise2*2 / Trouble Codes.
*1: Output from the ECM
*2: Output from the forward recognition camera
Select the DTCs (with snow icon) for which freeze frame data is recorded.
The operating conditions the moment a DTC is stored are recorded as freeze frame data. Furthermore, only the latest 3 DTCs can be stored by the forward recognition camera.
