System DescriptionBKS002BX
AFS (ADAPTIVE FRONT-LIGHTING SYSTEM)

Bending lamp (exclusive lamp for AFS) turn ON/OFF depending on the steering wheel angle and the vehi-
cle speed, when the headlamp LOW/HIGH lights, and the shift position is at any ranges except P.

Bending lamp supplies efficient light distribution for turning intersection and driving on the curves.

When turning to the left (right), bending lamp left (right) turn ON/OFF while driving forward or backward.

direct,

through 15A fuse (No. 71, located in IPDM E/R)

to CPU (central processing unit) in IPDM E/R,

through 15A fuse (No. 78, located in IPDM E/R)

to CPU in IPDM E/R,

through 10A fuse (No. 38, located in fuse and fusible link block)

to AFS control unit terminal 6.
With the ignition switch in the ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

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

through grounds M71 and M72.
BENDING LAMP OPERATION
Bending lamp right/left turn ON depending on the steering wheel angle and the vehicle speed under the oper-
ating condition. Bending lamp right/left turn OFF when the steering wheel is returned to the straight.

CAN Communication System DescriptionBKS0041K
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 UnitBKS0041L

Operation Procedure (without VDC)
1. Stop the vehicle at the straight-ahead position under the unladen condition (seat 1 person on the driver's
seat).
2. Touch ADAPTIVE LIGHT” on “SELECT SYSTEM” screen.
3. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
4. Touch “ST ANG SEN ADJUSTMENT” on “SELECT WORK ITEM” screen.
5. Touch “START”.
CAUTION:
Never touch steering wheel while adjusting steering angle
sensor.
6. When “ADJUSTMENT COMPLETE” is displayed, touch “END”.
7. Touch “SELF-DIAG RESULTS” on “SELECT DIAG MODE”
screen.
8. Make sure that “NO DTC” is displayed.
When “ [B2520] ST ANGLE SEN CALIB” is displayed

If the steering is turned during the adjustment, perform the
adjustment again.

If any condition other than above exists, check the connection
conditions between steering angle sensor, AFS control unit,
CONSULT-II and harnesses, and then perform the adjustment
again. After the adjustment is completed, replace AFS control
unit if [B2520] is not erased from self-diagnostic results.
CAUTION:
If [U1000] CAN COMM CIRCUIT or [B2515] ST ANG SEN SIG is displayed, first refer to LT- 8 4 ,
"SELF-DIAG RESULTS" of self-diagnostic results, and then perform the diagnosis.
9. Turn ignition switch OFF, and then turn ON again.
CAUTION:
Never skip this step.
10. Drive the vehicle to the straight-ahead position, and then stop it.
11. Select “ST ANG SEN SIG” on “SELECTION FROM MENU” screen of “DATA MONITOR” of CONSULT-II.
Make sure that “ST ANG SEN SIG” is within 0 ± 2.5°. If it is other than 0 ± 2.5°, perform steps 1 to 10
again.

DATA MONITOR
Operation Procedure
1. Touch ADAPTIVE LIGHT” on “SELECT SYSTEM” screen.
2. Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.
3. Touch either “ALL SIGNALS” or “SELECTION FROM MENU” on “SELECT MONITOR ITEM” screen.
4. When “ALL SIGNALS” is selected, all the items will be monitored. When “SELECTION FROM MENU” is
selected, touch items to be monitored.
5. Touch “START”.
6. Touch “RECORD” while monitoring, then the status of the monitored item can be recorded. To stop
recording, touch “STOP”.

AFS Operation Check (Function Test)BKS002FA
1. CHECK DIAGNOSIS RESULT
Select “ADAPTIVE LIGHT” on CONSULT-II. Select “SELF-DIAG
RESULTS” on “SELECT DIAG MODE” screen.
Is DTC detected?
YES >> Refer to LT- 8 4 , "SELF-DIAG RESULTS" .
NO >> GO TO 2.
2. CHECK SIFT SIGNAL AND HEAD LAMP SIGNAL
1. Select “ADAPTIVE LIGHT” on CONSULT-II. Select “DATA
MONITOR” on “SELECT DIAG MODE” screen.
2. When operating select lever and lighting switch, check indication
of the following item.
OK or NG
OK >> GO TO 3.
NG >>

When “SLCT LVR POSI” does not change depending on select lever operation, refer to AT- 1 6 6 ,
"PNP SWITCH" (with A/T) or CVT-62, "DTC P0705 PARK/NEUTRAL POSITION SWITCH"
(with CVT). If above system is normal, replace AFS control unit. Refer to LT- 9 4 , "Removal and
Installation of AFS Control Unit" .

When “HEAD LAMP LO”, “HEAD LAMP HI” does not change depending on lighting switch
operation, refer to LT- 7 5 , "
System Description" . If above system is normal, replace AFS control
unit. Refer to LT- 9 4 , "
Removal and Installation of AFS Control Unit" .
3. CHECK STEERING ANGLE SENSOR
Check “STR ANGLE SIG” in “DATA MONITOR” when steering wheel
is driving straight and steering turn 90° to right or left.
OK or NG
OK >> GO TO 4.
NG >>

When steering is out of range while driving straight,
perform steering angle sensor adjustment. Refer to LT- 8 2 , "
WORK SUPPORT" .

When the function is normal while driving straight but the displayed value is different from
actual steering position with turning to right or left, replace steering angle sensor. Refer to LT-
94, "Removal and Installation of Steering Angle Sensor" .
