CAUTION:
Optical sensor must be securely subjected to work lamp light. If the optical sensor is insufficiently
illuminated, the measured value may not satisfy the standard.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between BCM harness connector M1 terminal 14
and ground.
CAUTION:

ACTIVE AFS
Revision: 2006 January2006 M35/M45
through front combination lamp RH terminal 21.
Swivel position sensor detects swivel angle during ignition switch ON, and transmits swivel position sensor
signals to the AFS control unit:
When ignition switch is turn to ON position, power is supplied
to front combination lamp RH terminal 15
through AFS control unit terminal 4.
When ignition switch is turn to ON position, swivel position sensor input signal is supplied
to AFS control unit terminal 9
through front combination lamp RH terminal 14.
Ground is supplied
to front combination lamp RH terminal 19
through AFS control unit terminal 2.
The low beam headlamp RH starts to swivel to the right.
The swivel motor driving signals are blocked and the swivel motion stops when the steering angle reaches
approximately more than 80 degrees (predetermined). The low beam headlamp will not swivel any further no
matter how further right. As the steering wheel is turned back to the left, the swivel motor driving signals (both
1-phase and 2-phase) will be reversed, causing low beam headlamp RH to start swiveling to the left. When
steering angle becomes smaller than predetermined value, the low beam headlamp is set in the straight-
ahead position, swivel motor driving signals are blocked and low beam headlamps stop swiveling.
AFS OFF INDICATOR OPERATION
In response to the state of control, AFS control unit switches com-
mands of AFS off indicator signal sent to unified meter and A/C amp.
via CAN communication; and then turns on/off or blinks AFS off indi-
cator lamp built in the combination meter depending on the following
condition.
Bulb check operation
AFS off indicator lamp is turned off after illuminating for one sec-
ond as a bulb check for AFS off indicator lamp when turn ignition
switch ON is detected.
NOTE:
AFS off indicator lamp is turned off without a lapse of one sec-
ond when start of the engine is detected.
AFS switch operation
AFS off indicator lamp is illuminated while AFS switch is OFF.
AFS off indicator lamp is turned off while AFS switch is ON.
System warning operation
AFS off indicator lamp illuminates at intervals of approximately one second when AFS control unit detects
any specific DTC (diagnosis trouble code), or when unified meter and A/C amp. cannot receive AFS off
indicator signals.
NOTE:
Unified meter and A/C amp. transmits a command to combination meter to blink AFS off indicator lamp
when they cannot receive AFS off indicator signal.
SWIVEL ACTUATOR INITIALIZATION
AFS control unit performs swivel operation to initialize swivel actuator when start of the engine is detected.
Straight-ahead position of low beam headlamps is adjusted by turning low beam headlamps to outside vehicle
with specified swivel angle after turning it to the center of vehicle and making sure that it reaches the stopper.
Swivel actuator initialization shall be performed every time when start of the engine is detected.

CONSULT-II Function (ADAPTIVE LIGHT)NKS003QM
CONSULT-II can display each diagnostic item using diagnostic test modes shown following.
CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
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. Touch “START (NISSAN BASED VHCL)”.
3. Touch “ADAPTIVE LIGHT” on “SELECT SYSTEM” screen. If
“ADAPTIVE LIGHT” is not indicated, check power supply and
ground of AFS control unit. If it is normal, refer to GI-40, "
CON-
SULT-II Data Link Connector (DLC) Circuit" in “GI section”.
