Description
OUTLINE OF RADAR ALIGNMENT PROCEDURE
  • A 4-wheel vehicle alignment must be performed before proceeding with radar alignment procedure.
  • Always perform the radar alignment after removing and installing or replacing the distance sensor.
warningRadio waves could adversely affect electric medical equipment. Those who use a pacemaker should contact the electric medical equipment manufacturer for the possible influences before use.
cautionThe system does not operate normally unless the radar alignment is performed. Always perform it.
  1. Set the target board (SST: KV99112700) to the correct position in front of the vehicle.
  2. Set the radar alignment mode (“MILLIWAVE RADAR ADJUST” on “SPECIAL FUNCTION”) with M.U.T.-III SE, and then perform the adjustment according to the display. (Distance sensor automatically adjusts.)
CAUTIONARY POINT FOR RADAR ALIGNMENT PROCEDURE
caution
  • For radar alignment procedure, choose a level location with a few meter of working space in front and surrounding the vehicle.
  • Vehicle must be stationary and unoccupied during the whole alignment procedure.
  • Any slight vibration during the alignment procedure can cause the test to fail. If this happens, you will have to restart the alignment process.
  • The electric motor switch must be in the ON.
  • The battery voltage must not fall below 12 volts during the whole alignment procedure. Failure to maintain adequate battery voltage will cause the test to fail. If this happens, you will have to restart the alignment process.
  • The target board must be set in front of the vehicle facing the sensor.
  • Adjust the radar alignment with M.U.T.-III SE. (The radar alignment procedure cannot be adjusted without M.U.T.-III SE.)
  • Never enter the vehicle during radar alignment.
  • Never block the area between the radar and the target board at any time during the alignment process.
  • Accurate steering wheel setting is crucial. Once set, do not disturb the steering wheel for the remainder of the alignment procedure.
  • For proper system operation and adjustment, all vehicle wheels must be of the same size.
 
 
Preparation
1.ADVANCE PREPARATION FOR RADAR ALIGNMENT
  1. Adjust all tire pressure to the specified value.
  2. Empty the vehicle. (Remove any luggage from the passenger compartment, trunk room, etc.)
  3. Shift the selector lever to “P” position, and release the parking brake.
  4. Fully fill the fuel tank, and then check that the coolant and oils are filled up to correct level.
  5. Clean the distance sensor area of the front bumper grille.

Setting The Target Board
Accurate adjustment of the radar alignment requires that the target board be accurately positioned.
cautionIf the radar alignment is adjusted with the target board in the incorrect position, the FCM/PFCW systems do not function normally.
1.TARGET BOARD HEIGHT ADJUSTMENT
Set the target board up to adjustable maximum height.

2.PREPARATION OF SETTING TARGET BOARD (1)
“A”–“E” (“C”–“F”) : 2000 mm (78.7 in)
  1. Mark points “A”, “B”, “C” and “D”at the center of the lateral surface of each wheels.
    noteHang a string with a cone from the fender so as to pass through the center of wheel, and then mark a point at the center of the lateral surface of the wheel.
  2. Draw line “LH” passing through points “A” and “B” on the left side of vehicle.
    noteApproximately 2 m (6.56 ft) or more from the front end of vehicle.
  3. Mark point “E” on the line “LH” at the positions 2000 mm (78.7 in) from point “A”.
  4. Draw line “RH” passing through points “C” and “D” on the right side of vehicle in the same way as step 2.
    noteApproximately 2 m (6.56 ft) or more from the front end of vehicle.
  5. Mark point “F” on the line “RH” at the positions 2000 mm (78.7 in) from point “C”.
  6. Draw line “FW” passing through the points “E” and “F” on the front side of vehicle.
  7. Mark point “X” at the center of point “E” and “F” on the line “FW”.
    cautionMake sure that “E” to “X” is equal to “F” to “X”.

3.SETTING TARGET BOARD
Place the center of target board on point “G” at line “E-F” and install the target board.
cautionFor performing the radar alignment correctly, securely install (target board) to be parallel with the “E-F” line.
L1: 2000 mm (78.7 in)
L2: 0 mm (0 in)

Radar Alignment
The radar alignment is performed automatically with M.U.T.-III SE.
cautionPerform all necessary work for radar alignment until the adjustment completes as shown in the procedure. If the procedure does not complete, the FCM/MI PILOT Assist/PFCW systems are inoperable.
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”.
    noteConfirm 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.
    cautionNever select “Start” when the target is not accurately placed.
  5. Select “Next” after the “Radar alignment conditions are ready.” screen is displayed.
    noteIf 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.

    Vertical Alignment valueRadar measurement result(3.0°) - (- 2.5°)
    State of radar in alignmentExecuted 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”.
    cautionOnce “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.
