Freeze Frame Data [08/2019 - ]
- DESCRIPTION
- Whenever a front radar sensor system DTC is stored, the millimeter wave radar sensor assembly stores the current vehicle state as Freeze Frame Data.
- CHECK FREEZE FRAME DATA
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Body Electrical / Front Radar Sensor / Trouble Codes.
Body Electrical > Front Radar Sensor > Trouble Codes
- According to the display on the Techstream, select a DTC with freeze frame data.
- Read the freeze frame data recorded when the DTC was stored.
