Components Description
NOTE:
*: This indicates in a few seconds for the system check during ignition switch ON.
POWER SUPPLY AND GROUND CIRCUIT
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 12, located in the fuse block (J/B)]

to LDW camera unit terminal 1.
Ground is supplied

to LDW camera unit terminals 6 and 12

through grounds M16 and M70.
Action TestNKS003VH
LDW SYSTEM RUNNING TEST
WARNING:

Be careful when performing road test.

Understand “Precautions” and “System Description” well before the road test. Refer to DI-75,
"Precautions for Lane Departure Warning (LDW) system" and DI-75, "System Description" .
Function Check
Check the LDW system operation according to the condition that the warning function works. Refer to DI-75,
"LDW SYSTEM OPERATION" .
PKIC0698E
Component Description
LDW camera unitDetects the lane marker by the built-in camera, gives judgement for the warning according to the
result of detection and signals from each unit, and transmits the operation signal to LDW chime and
LDW indicator lamp.
LDW switch

Selects ON/OFF of the system.

Indicates ON/OFF of the signal with LDW system ON indicator.
LDW chime Gives a warning chime according to the direction from LDW camera unit.
LDW indicator lampInstalled in combination meter, and indicates the system condition.

Blinks when LDW system is functioning to alert the driver.

Stays on when LDW system is malfunctioning.*
BCM Transmits turn indicator signal to LDW camera unit with CAN communication signal.
ABS actuator and electric unit
(control unit)Transmits vehicle speed signal to LDW camera unit with CAN communication signal.

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)”.
