DYNAMIC RADAR CRUISE CONTROL SYSTEM FREEZE FRAME DATA


  1. CHECK FREEZE FRAME DATA

    Tech Tips

    The ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored.


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Radar Cruise 1 or Radar Cruise 2 / Trouble Codes.

    5. From the DTC screen, select the DTCs (with snow icon) for which freeze frame data is recorded.
