–LDW system ON indicator located on the LDW switch illuminates, indicating that the system is on.
–To cancel LDW system, push the LDW switch to turn off LDW system ON indicator.
–To turn on the system, push LDW switch again.
In the manual mode
–LDW system is still off when the ignition switch is turned to the ON position.
–The LDW switch must be pushed to turn on the system.
To the change modes
–Push and hold LDW switch for more than 4 seconds, when LDW system ON indicator is off.
–Then LDW chime sounds and blinking of LDW system ON indicator informs that the mode change is com-
pleted.

Temporary disabled status at high temperature
–If the vehicle is parked in direct sunlight under high temperature conditions [approximately over 104 °F
(40 °C)] and then started, the LDW system may sound a chime and cancel automatically. Then LDW sys-

System Diagram
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 M45, M85 and M35.
SKIB1784E
Component Description
LDW camera unit Detects 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 lamp Installed 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.
TCM Transmits vehicle speed signal to LDW camera unit with CAN communication signal. (For detecting
incorrect speed.)

“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)”.
