COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (or if auto light system is activated), and
the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
DELAY TIMER FUNCTION
Delay timer function carries out a function that BCM activates the timer and controls lights out of headlamps by
door switch signal and lightning switch signal when turning the Ignition switch OFF while it is ON and head-
lamps are ON by the auto light function.
Timer types are a 5 minutes timer and a 45 seconds timer
When opening any door (door switch is ON), the 5 minutes timer starts and then headlamps go out five
minutes later
When all the doors are closed (from door switch ON to OFF), the 45 second timer starts and then head-
lamps go out 45 seconds later. If any door is opened (door switch ON) while the 45 seconds timer is in
operation, the 5 minutes timer starts again
The timer stops when turning on the ignition switch or turning off the auto light switch under the above
conditions.
Delay timer control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionNKS003Q0
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 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 the high rate of information transmission with less wir-
ing. Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS003Q1
Refer to LAN-34, "CAN Communication Unit" .

System DescriptionNKS003QF
AFS control unit controls AFS and headlamp auto aiming.
The following signals are input to AFS control unit via CAN communication:
Steering angle sensor signal
A/T position indicator signal
Low beam status signal
Vehicle speed signal
Engine speed signal
Other signals are input as follows:
AFS switch signal from AFS switch connected to AFS control unit
Height sensor signal from height sensor connected to AFS control unit
Swivel position sensor signal from swivel position sensor built into both right and left swivel actuators con-
nected to AFS control unit
In response to the state of control, AFS control unit switches commands of AFS off indicator signal sent to uni-
fied meter and A/C amp. via CAN communication; and then turns on/off or blinks AFS off indicator lamp built in
the combination meter.
AFS (ADAPTIVE FRONT-LIGHTING SYSTEM)
AFS increases viewability of cornering direction by changing light axis automatically to the direction of travel
with low beam headlamps during vehicle's cornering.
AFS switch allows AFS function to be stopped.
AFS control unit determines the current vehicle conditions by each received signals, and sends commands to
the low beam headlamp to swivel. With the headlamps (HIGH/LOW) illuminated, the AFS switch on, engine
running and the A/T select lever in any position but range P or range R, the low beam headlamps are opera-
tive by AFS control unit commands.
As the steering wheel is turned to the left (right), the left (right) low beam headlamp will automatically swivel
angle in accordance with the steering angle and vehicle speed, and stop the operation when the steering
wheel is returned to the straight-ahead position.
Swivel operation allows drive signal to be sent to the swivel actuator on the side that AFS control unit is actu-
ated. Step motor built in swivel actuator adjusts low beam projector of headlamp to swivel angle that matches
drive signal. Swivel position sensor built in swivel actuator detects swivel angle and transmits a swivel position
sensor signal to the AFS control unit. AFS control unit monitors if swivel operation is performed normally via
swivel position sensor signal.
Swivel operation
*1: Included high beam illuminated.
*2: The swivel operates when running at approx. 25 km/h (15.5 MPH). When swivel operation is started, it works on until vehicle
stops.
*3: The low beam headlamps perform small movements when AFS control unit detects start of the engine. This is normal with ini-
tialization of swivel actuator by AFS control unit.Low beam

AFS OPERATION
When The Steering Wheel Is Turned To The Left
Swivel motor driving signal (1-phase) is transmitted when the steer-
ing wheel is turned to left approximately more than 10* degrees
(predetermined), with vehicle speed at approximately 25 km/h (15.5
MPH) or more, headlamps (HIGH/LOW) illuminated, AFS switch ON
and the engine running and the A/T select lever in any position
except range P or R.
* : Slightly different from the case when it is turned to the right.
Swivel motor driving signal (1-phase) is sent
to front combination lamp LH terminal 17
through AFS control unit terminal 15,
to AFS control unit terminal 38
through front combination lamp LH terminal 21.
And swivel motor driving signal (2-phase) is sent:
to front combination lamp LH terminal 16
through AFS control unit terminal 17,
to AFS control unit terminal 36
through front combination lamp LH terminal 20.
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 LH terminal 15
through AFS control unit terminal 24.
When ignition switch is turn to ON position, swivel position sensor signal input is supplied
to AFS control unit terminal 29
through front combination lamp LH terminal 14.
Ground is supplied
to front combination lamp LH terminal 19
through AFS control unit terminal 27.
The low beam headlamp LH starts to swivel to the left.
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 left. As the steering wheel is turned back to the right, the swivel motor driving signals (both
1-phase and 2-phase) will be reversed, causing low beam headlamp LH to start swiveling to the right. 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.
When The Steering Wheel Is Turned To The Right
Swivel motor driving signal (1-phase) is transmitted when the steer-
ing wheel is turned to right approximately more than 10* degrees
(predetermined), with headlamps (HIGH/LOW) illuminated, AFS
switch ON, the engine running and the A/T select lever in any posi-
tion except range P or R.
* : Slightly different from the case when it is turned to the left.
Swivel motor driving signal (1-phase) is sent
to front combination lamp RH terminal 16
through AFS control unit terminal 34,
to AFS control unit terminal 11
through front combination lamp RH terminal 20.
And swivel motor driving signal (2-phase) is sent
to front combination lamp RH terminal 17
through AFS control unit terminal 32,
to AFS control unit terminal 13

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.
