Camera Aiming AdjustmentNKS00315
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.

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”.
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. With the ignition switch OFF, connect CONSULT-II and CON- SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
2. Start the engine, wait for at least 10 seconds, and touch “START (NISSAN BASED VHCL)”.
