FREEZE FRAME DATA
CHECK FREEZE FRAME DATA
HINT:
The ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored.
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Radar Cruise 1*1 or Radar Cruise 2*2 / Trouble Codes.
Powertrain > Radar Cruise1 > Trouble Codes Powertrain > Radar Cruise2 > Trouble Codes(e) Select the DTCs (with snow icon) for which freeze frame data is recorded.
NOTICE:
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.
