TYPE 1

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.

Warning:

WARNING: Radio 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.

CAUTION:

The system does not operate normally unless the radar alignment is performed. Always perform it.

Set the target board (SST: KV99112700) to the correct position in front of the vehicle.
Set the radar alignment mode ("MILLIWAVE RADAR ADJUST" on "Work support") with CONSULT, 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 ignition switch must be in the ON position.
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 CONSULT. (The radar alignment procedure cannot be adjusted without CONSULT.)
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

ADVANCE PREPARATION FOR RADAR ALIGNMENT

Adjust all tire pressure to the specified value.
Empty the vehicle. (Remove any luggage from the passenger compartment, trunk room, etc.)
Shift the selector lever to "P" position, and release the parking brake.
Fully fill the fuel tank, and then check that the coolant and oils are filled up to correct level.

Clean the distance sensor area

of the front bumper grille.

Refer to Vehicle Set Up.

Vehicle Set Up

Accurate adjustment of the radar alignment requires that the target board, wheel adapter, laser assembly, and rear stand be properly positioned.

CAUTION:

If the radar alignment is adjusted with the target board, wheel adapter, laser assembly, or rear stand in the incorrect position, the FEB/PFCW systems will not function properly or the alignment procedure may not be completed successfully.

PREPOSITION TARGET BOARD

NOTE:

To identify the sensor wave axis center, measure the point

as shown in the illustration.

A	: 0 mm (0 in)
B	: 397.8 mm (15.66 in)
C	: Vehicle center

Target board setting must be in the center position. (Position 2)
Attaching the distance sensor alignment kit attachment board to the target board.

Position the target board in front facing the right front side of the vehicle:

Courtesy of NISSAN NORTH AMERICA, INC.

Place the marked center of the target board 397.8 mm (15.66 in) ± 50 mm (1.97 in) facing the distance sensor.
Adjust the height of the target board using the adjustable nut to achieve the proper height. The up/down tolerance is ± 30 mm (1.18 in).
Adjust the target board lateral position aligning the marked center of the board horizontally with the center of the distance sensor. The right/left tolerance is ± 80 mm (3.15 in).

Extend the machined arm of the target board exposing the reflective surface to the right front side of the vehicle.

Place one side of the laser assembly

flush against the center of the target board

to assist in the positioning.

Courtesy of NISSAN

Turn the laser assembly ON allowing the laser beam to emit through the opening of the laser assembly toward the center of the distance sensor.
Move the target board as necessary so that center of target board aligns with center of distance sensor.
Turn the laser assembly OFF when done.

Are using Hunter alignment equipment?

YES>>

Refer to Hunter's equipment instructions for complete vehicle set up and target board setting. Then, refer to Distance Sensor Adjustment.

NO>>

INSTALLING LASER ASSEMBLY

NOTE:

Insure the steering wheel is positioned in the center straight forward position.
Insure all 4 vehicle wheels do not contain any physical damage.

Install the wheel adapter

on the right front wheel.

Courtesy of NISSAN NORTH AMERICA, INC.

Mount the laser assembly to the wheel adapter as shown in the figure.
NOTE: When the power switch is turned ON, the front laser signal will be emitted toward the front target board, and the rear laser signal will be emitted toward the rear of the vehicle.

GO TO 3.

SETTING UP REAR STAND

Place the rear stand next to the right rear tire as shown in the figure, below.

Courtesy of NISSAN

Turn the laser assembly ON allowing the laser beam to be emitted through the front and rear laser assembly openings.
Measure and record the distance (D_r

) between the edge of the right rear wheel and the laser beam on the rear stand (horizontal line).

Measure and record the height (H_r
) between the laser beam on the rear stand and ground level (vertical line).
Measure and record the distance (D_r ) between the edge of the right front wheel and the laser beam signal/opening
on the laser assembly (horizontal line).

Measure and record the height (H_r ) between the laser beam signal/opening on the laser assembly and ground level (vertical line).
NOTE:
- Horizontal adjustment [front distance (D_f )
- Vertical adjustment [front height (H_f )
- Directional arrows and are shown to illustrate the direction of the laser assembly beams.
Adjust laser beam as necessary until the two distances match and the two heights match.
NOTE: Must be verify both horizontal and vertical adjustments anytime one adjustment is made.

Refer to Setting The Target Board.

Setting The Target Board

Accurate adjustment of the radar alignment requires that the target board be accurately positioned.

CAUTION:

If the radar alignment is adjusted with the target board in the incorrect position, the FEB/PFCW systems will not function properly or the alignment procedure may not be completed successfully.

TARGET BOARD FINAL SETTING

With the target board arm extended, the laser beam

emitted by the laser assembly

will be reflected back

toward the laser assembly.

Courtesy of NISSAN

NOTE:

When adjusted properly, reflected laser beam

must align with emitted laser beam

and the two laser beams will be seen as one.

Rotate the target board to achieve the necessary horizontal adjustment.
Adjust the target board leveling screws to achieve the necessary vertical adjustment.

The figure shown illustrates the laser beam

emitted by the laser assembly

and its reflection

off of the target board arm.
