Radar Alignment

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

1. PERFORM RADAR ALIGNMENT 
   1. Start the engine.
   2. Connect M.U.T.-III SE and select "Work support" 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
      Alignment result is over threshold.	DTC is detected The position of the target board is incorrect Vehicle is moving	Check the vehicle alignment condition and perform radar alignment again
      Horizontal value is over threshold. Check the condition. Perform the adjust again.	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
      Vertical value is over threshold. Check the condition. Perform the adjust again.	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
      Horizontal value and Vertical value are over threshold. Check the condition. Perform the adjust again.	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
      This display direction is looking from driver seat side.	NOTE: This is not an error message, so service procedures are not required.
      Target is not detected. (Reflection radio waves is weak.) Reconfirm the placing condition, and then re-perform adjustment.	A target is not-yet-placed The position of the target board is incorrect The position of the distance sensor is incorrect	Check the vehicle alignment condition and perform radar alignment again
      Target setting is offset in horizontal direction. Reconfirm the placing condition. And then re-perform adjustment or re-install the radar.	The position of the target board is shifted horizontally The position of the distance sensor is shifted horizontally	Check the vehicle alignment condition and perform radar alignment again
      Displayed item	Possible cause	Service procedure
      Target setting is offset in vertical direction. Reconfirm the placing condition. And then re-perform adjustment or re-install the radar.	The position of the target board is shifted vertically The position of the distance sensor is shifted vertically	Check the vehicle alignment condition and perform radar alignment again
      EEPROM writing is error. Re-perform adjustment or replace the ECU.	The condition of the alignment is incorrect Distance sensor malfunction	Check the vehicle alignment condition and perform radar alignment again If same massage displays again, replace the distance sensor
      Hardware is imperfect. Replace the ECU.	Distance sensor hardware has trouble for alignment	Replace the distance sensor
      Signal of vehicle side is imperfect or combination of ECU is incorrect. Diagnose the other ECU.	Other ECU except distance sensor have trouble for alignment	Check if any DTC is detected in "Self Diagnostic Result" of other ECU except distance sensor If any DTC is not detected, replace the distance sensor
      Software is incorrect. Replace the ECU.	Distance sensor software is incorrect	Replace the distance sensor

   7. Confirm displayed value.

      Displayed item	Monitor item		Reference value
      Completed	Vertical Angle	Radar angle	"DownW" or "UpW"
      	Vertical Angle	Radar measurement result	(- 2.50) - (+ 3.00)
      	Horizontal Angle	Radar angle	"LeftW" or "RightW"
      	Horizontal Angle	Radar measurement result	Less than 0 ± 4.00 deg
      	Alignment status	Alignment complete

      • 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 "End".
      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 AEB/MI-PILOT Assist/PFCW systems cannot operate.
