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.

TURN SIGNAL AND HAZARD WARNING LAMPS
Revision: 2006 January2006 M35/M45
LH Turn Signal Lamp
When turn signal switch is moved to left position, BCM receives input signal requesting left turn signals to
flash. BCM then supplies power
through BCM terminal 45
to front combination lamp LH (turn signal) terminal 10
to side turn signal lamp LH terminal 1, and
to rear combination lamp LH (turn signal) terminal 3.
Ground is supplied
to front combination lamp LH (turn signal) terminal 9
to side turn signal lamp LH terminal 2
through grounds E22 and E43,
to rear combination lamp LH (turn signal) terminal 4
through grounds B5, B40 and B131.
The BCM also supplies input to unified meter and A/C amp. terminals 56 and 72 across the CAN communica-
tion lines.
The unified meter and A/C amp. which received the turn indicator signal makes the left turn signal indicator
turn on in combination meter.
With power and input supplied, the BCM controls the flashing of the LH turn signal lamps.
RH Turn Signal Lamp
When turn signal switch is moved to right position, BCM receives input signal requesting right turn signals to
flash. BCM then supplies power
through BCM terminal 46
to front combination lamp RH (turn signal) terminal 10
to side turn signal lamp RH terminal 1, and
to rear combination lamp RH (turn signal) terminal 3.
Ground is supplied
to front combination lamp RH (turn signal) terminal 9
to side turn signal lamp RH terminal 2
through grounds E22 and E43,
to rear combination lamp RH (turn signal) terminal 4
through grounds B5, B40 and B131.
The BCM also supplies input to unified meter and A/C amp. terminals 56 and 72 across the CAN communica-
tion lines.
The unified meter and A/C amp. which received the turn indicator signal makes the right turn signal indicator
turn on in combination meter.
With power and input supplied, the BCM controls the flashing of the RH turn signal lamps.
HAZARD LAMP OPERATION
Power is supplied at all times
through 50A fusible link (letter F, located in fuse, fusible link and relay block)
to BCM terminal 55,
through 10A fuse [No. 21, located in fuse block (J/B)]
to BCM terminal 42
to combination meter terminal 23,
through 10A fuse [No. 19, located in fuse block (J/B)]
to unified meter and A/C amp. terminal 54.
When the hazard switch is depressed, ground is supplied
to BCM terminal 29
through multifunction switch terminal 6.
Ground is supplied
to multifunction switch terminal 14

COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
CAN Communication System DescriptionNKS003RM
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS003RN
Refer to LAN-34, "CAN Communication Unit" .
