Freeze Frame Data [12/2021 - ]

  1. DESCRIPTION 
    1. Whenever a front radar sensor system DTC is stored, the millimeter wave radar sensor assembly stores the current vehicle state as Freeze Frame Data.
  2. CHECK FREEZE FRAME DATA 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Body Electrical / Front Radar Sensor / Trouble Codes.

      Body Electrical > Front Radar Sensor > Trouble Codes 

    5. According to the display on the Techstream, select a DTC with freeze frame data.
    6. Read the freeze frame data recorded when the DTC was stored.
  3. FREEZE FRAME DATA CHART 
    1. Read the freeze frame data recorded when the DTC was stored.
