Radar Alignment

The radar alignment is performed automatically with M.U.T.-III SE.

1. PERFORM RADAR ALIGNMENT 
   1. Change the power supply mode of the electric motor switch to ON.
   2. Connect M.U.T.-III SE and select "Special Function" of "LASER/RADAR".
   3. Select "MILLIWAVE RADAR ADJUST".
      NOTE: Confirm the following items;

      • The target should be accurately placed.
      • The vehicle should be stopped.
   4. Select "Start" after the conditions displayed on M.U.T.-III SE are satisfied.
      CAUTION: Never select "Start" when the target is not accurately placed.
   5. Select "Next" after the "Radar alignment conditions are ready." screen is displayed.
      NOTE: If the radar is in alignment at this time, "In progress" is displayed. It may take several 10s of seconds until the result is displayed.
   6. Confirm the displayed item.
      • "Completed.": Go to  7.
      • Except "Completed.": Perform the following services.

      Displayed item	Possible cause	Service procedure
      "Error: Horizontal is over threshold. Check the condition." After selecting "OK", calibration can be performed from the beginning. You will return to the initial screen.	DTC is detected The position of the target board is shifted horizontally Vehicle is moving	Check the vehicle alignment condition and perform radar alignment again
      "Error: Vertical value is over threshold. Check the condition." After selecting "OK", calibration can be performed from the beginning. You will return to the initial screen.	DTC is detected The position of the target board is shifted vertically Vehicle is moving	Check the vehicle alignment condition and perform radar alignment again
      "Error: Horizontal and Vertical value are over threshold. Check the condition." After selecting "OK", calibration can be performed from the beginning. You will return to the initial screen.	DTC is detected The position of the target board is shifted horizontally and vertically Vehicle is moving	Check the vehicle alignment condition and perform radar alignment again
      Alignment conditions not ready Vehicle moving (or vehicle speed km/h)	Vehicle is moving	Check the vehicle alignment condition and perform radar alignment again
      Alignment conditions not ready System Failure detected	A target is not-yet - placed The position of the target board is incorrect DTC is detected	Check the vehicle alignment condition and perform radar alignment again
      Alignment conditions not ready System Failure detected and Vehicle moving (or vehicle speed 0 km/h)	DTC is detected The position of the target board is incorrect Vehicle is moving	Check the vehicle alignment condition and perform radar alignment again
      Alignment condition not ready	The condition of the alignment is incorrect	Check the vehicle alignment condition and perform radar alignment again
      Operation has been stopped due to following reasons. Vehicle condition is out of test condition. No response form Vehicle ECU. Refer to Service Information, confirm test condition and vehicle condition. Then try again.	DTC is detected The condition of the alignment is incorrect Distance sensor hardware has trouble for alignment The ACC/FCM-ECU is not properly installed.	Check the vehicle alignment condition and perform radar alignment again Check the installation condition of the ACC/FCM-ECU.

   7. Confirm displayed value.

      Displayed item	Monitor item		Reference value
      Finish Alignment	Horizontal Alignment value	Radar measurement result	(3.7°) - (- 3.7°)
      	Vertical Alignment value	Radar measurement result	(3.0°) - (- 2.5°)
      	State of radar in alignment	Executed without errors

      • Within reference value: Go to  8.
      • Outside of reference value: Check the target board condition and perform radar alignment again.
      NOTE:

      • Check the condition of the distance sensor installation.
      • Check the vehicle for damage.
      • Replace distance sensor if it is outside the reference value, even when distance sensor installation is installed normally and the vehicle is not damaged.
   8. Select "back".
      CAUTION: Once "MILLIWAVE RADAR ADJUST" is started with M.U.T.-III SE, always continue the work until the horizontal radar alignment is completed successfully. If the job is stopped midway, the radar alignment is not adjusted and the FCM/MI PILOT Assist/PFCW systems cannot operate.
