Camera Aiming Adjustment

Camera Aiming Adjustment

OUTLINE
Adjust the camera aiming every time the LDW camera unit is removed or installed.

CAUTION:
- Place the vehicle on the level ground when the camera aiming adjustment is operated.
- Follow the CONSULT-II when adjusting the camera aiming. (Camera aiming adjustment cannot be operated without CONSULT-II.)

PREPARATION
- Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure value.
- There is no-load in vehicle. Check if coolant, engine oil are filled up to correct level and fuel tank is full.
- Shift the gear into "P" position and release the parking brake.
- Clean the windshield.

NOTE: Do not place anything reflective on the upper surface of instrument panel.

TARGET SETTING

Preparation Aiming Adjustment Jig




For aiming adjustment, prepare the following jigs and targets.




Target

Target Setting






CAUTION:
- Perform this operation in a horizontal position where there is a clear view for 5 m (16.4 ft) forward and 3 m (9.84 ft) wide.
- Place the target at a well-lighted location. (Poor lighting may make it hard to adjust.)
- The target may not be detected when there is a light source within 1.5 m (4.92 ft) from either side and within 1 m (3.28 ft) upward/downward from the target.
- Make sure location of the sun. (Sunlight should not shine directly on front of the vehicle.)
- The target may not be detected when there is the same pattern of black and white as the target when the pattern is within 1 m (3.28 ft) from either side and upward/downward position from the target. (It is desirable that the vehicle is positioned on the opposite side of a single-color wall.)




1. Mark a point at the center of lateral surface of each wheels ("A", "B", "C" and "D").

NOTE: Dangle 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 lateral surface of wheels.

2. Draw a line passing through points "A" and "B" on the left side of vehicle (line "LH").

NOTE: Approximately 4 m (13.12 ft) or more from the forward end of vehicle.

3. Mark points on the line "LH", at the positions 3850 mm (151.57 in) from the point "A" ("E").
4. Draw a line passing through the points "C" and "D" on the right side of vehicle as with the step 2 (line "RH").

NOTE: Approximately 4 m (13.12 ft) or more from the forward end of vehicle.

5. Mark points on the line "RH", at the positions 3850 mm (151.57 in) from the point "C" ("F").
6. Draw a line passing through the points "E" and "F" (line "FW").




7. Mark point at the center of the point "E" and "F", on the line "FW".

CAUTION: Make sure that "E" through "X" is equal to "F" through "X".

8. Position the center of the right target to the point of "X".

VEHICLE HEIGHT CHECK




Measure the wheel arch height. And calculate "Dh".
Dh [mm] = (Hfl + Hfr) ± 2 - 840
where,
Hfl: Front left wheel arch height [mm]
Hfr: Front right wheel arch height [mm]

NOTE: "Dh" may be calculated as a minus value.

AIMING ADJUSTMENT

Operation Procedure

CAUTION:
- Perform the adjustment under unloaded vehicle condition.
- LDW indicator is turned off after the removal/installation, and blinks after replacement.

1. Turn ignition switch OFF.




2. Connect CONSULT-II and CONSULT-II CONVERTER on the data link connector.




3. Start the engine, wait for at least 10 seconds, and touch "START (NISSAN BASED VHCL)".




4. Touch "LDW".
If "LDW" is not displayed, go to GI-40, "CONSULT-II Data Link Connector (DLC) Circuit". Data Link Connector Schematic




5. Touch "WORK SUPPORT".




6. Touch "AUTO AIM".




7. The target should be accurately placed.
The vehicle should be stopped.
After confirming the above, touch "START" to perform aiming.

CAUTION: Never touch "START" when the target is not placed.




8. Touch "NEXT", then a keyboard window is displayed. And input "Dh", and then touch "ENTER".

NOTE: Check the value "Dh". Refer to "VEHICLE HEIGHT CHECK".




9. Check the regulated value. (Spec.)

NOTE: Check the value input at step 8.

a. Touch "NEXT" if appropriate.
b. Touch "CHANGE SET" to change "Dh".




10. Touch "NEXT".

CAUTION: Never change "Ht".




11. Touch "NEXT".

CAUTION: Never change "Dt".




12. Touch "START".

13. Check it display item.




a. "NORMALLY COMPLETED" is displayed, then touching "COMPLETION".







b. Perform the following services when displayed "SUSPENSION" or "ABNORMALLY COMPLETED".




14. Check if "NORMALLY COMPLETED" is displayed and close the aiming adjustment procedure by touching "END".

Check After The Adjustment
1. Perform the LDW camera unit self-diagnosis. Refer to DI-98, "CONSULT-II Function (LDW)". Reading and Clearing Diagnostic Trouble Codes
2. Test the LDW system operation by running test. Refer to "LDW SYSTEM RUNNING TEST".
