Freeze Frame Data [08/2019 - ]
- CHECK FREEZE FRAME DATA
HINT:
The ECU records vehicle and driving condition information as freeze frame data the moment a 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 1*1 or Radar Cruise 2*2 / Trouble Codes.
Powertrain > Cruise Control > Trouble Codes
Powertrain > Radar Cruise2 > Trouble Codes
- *1: Output from the ECM
- *2: Output from the forward recognition camera
- Select the DTCs (with snow icon) for which freeze frame data is recorded.NOTE:
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.

High Temperature: Millimeter wave radar sensor assembly temperature is high- "High Temperature" displayed when the millimeter wave radar sensor assembly is in the following condition
- When the ambient temperature of the millimeter wave radar sensor assembly is 70°C (158°F) or more, such as when the vehicle is left alone in an extremely hot environment
- When "High Temperature" is displayed, and the dynamic radar cruise control system is in one of the following conditions
- X2027 in the vehicle control history (Front Radar Sensor Outside Guaranteed Operating Temperature) is stored
- "Radar Cruise Control Unavailable" is displayed on the multi-information display
- If "High Temperature" is displayed, refer to X2027 in the front radar sensor system vehicle control history
Front Radar Sensor Low Voltage Millimeter wave radar sensor assembly low voltage abnormality Normal or Low Voltage Normal: Millimeter wave radar sensor assembly voltage is normal
Low Voltage: Millimeter wave radar sensor assembly voltage is low- "Low Voltage" displayed when the millimeter wave radar sensor assembly is in the following condition
- When the input voltage is approximately 8 V or less, immediately after turning the engine switch is started
- When "Low Voltage" is displayed, and the dynamic radar cruise control system is in one of the following conditions
- X2028 in the vehicle control history (Front Radar Sensor Outside Guaranteed Operating Voltage) is stored
- "Radar Cruise Control Unavailable" is displayed on the multi-information display
- If "Low Voltage" is displayed, refer to X2028 in the front radar sensor system vehicle control history
- "High Temperature" displayed when the millimeter wave radar sensor assembly is in the following condition
