Freeze Frame Data [10/2014 - 09/2017]
- CHECK FREEZE FRAME DATA (READ BY TECHSTREAM)
HINT:
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 Techstream to the DLC3.
- Turn the engine switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Powertrain / Radar Cruise / Trouble Codes.
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.
