2006 INFINITI M35 low beam

LT-160
ACTIVE AFS
Revision: 2006 January2006 M35/M45
ACTIVE TEST
Operation Procedure
1. Start the engine. (Swivel actuator is initialized.)
2. Touch “ADAPTIVE LIGHT” on “SELECT SYSTEM” screen.
3. Touch “ACTIVE TEST” on “SELECT DIAG MODE” screen.
4. Touch “LOW BEAM TEST RIGHT”, “LOW BEAM TEST LEFT”, or “LEVELIZER TEST” on “SELECT TEST
ITEM” screen.
CAUTION:
Can be tested only when swivel actuator initialization is completed. If initialization is not com-
pleted, “RETRY COMMAND” is displayed and cannot be tested.
LOW BEAM TEST RIGHT
Low beam headlamp (right) can be operated to swivel angle
0
by touching “ORIGIN”, and to maximum angle by “PEAK”.
LOW BEAM TEST LEFT
Low beam headlamp (left) can be operated to swivel angle 0
by touching “ORIGIN”, and to maximum angle by “PEAK”.
LEVELIZER TEST
Aiming motor drive signal can be changed to approx. 85%
(ratio to IGN power supply) by touching “ORIGIN”, and to
approx. 15% by “PEAK”. That angles headlamp LO up and
down.
5. During the operation check, touching “BACK” deactivates the operation.

AFS Operation Check (Function Test)NKS003QS
1. CHECK SWIVEL ACTUATOR
1. Start engine and turn lighting switch to 2ND position.
2. Select “ADAPTIVE LIGHT” on CONSULT-II. Select “ACTIVE
TEST” on “SELECT DIAG MODE” screen.
3. Select “LOW BEAM TEST RIGHT” or “LOW BEAM TEST LEFT”
on “SELECT TEST ITEM” screen.
4. Touch “ORIGIN–FAST/SLOW” and “PEAK–FAST/SLOW”
screen.
5. Make sure of swivel operation.
OK or NG
OK >> GO TO 2.
NG >>
When interference or poor fitment is found, perform aiming adjustment. Refer to LT- 7 4 , "Aiming
Adjustment" . If it is normal, replace headlamp. Refer to LT- 1 9 0 , "Removal and Installation of
Front Combination Lamp" .
When the operation range is irregular, perform aiming adjustment. Refer to LT- 7 4 , "Aiming
Adjustment" . If it is normal, GO TO 3.
2. CHECK STEERING ANGLE SENSOR
Check “STR ANGLE SIG” in “Data Monitor” when driving straight
and steering turn 90
to right or left.
OK or NG
OK >> GO TO 3.
NG >>
When steering is out of range while driving straight, perform steering angle sensor adjustment.
Refer to BRC-6, "
Adjustment of Steering Angle Sensor Neutral Position" in “ON-VEHICLE
SERVICE”.
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-
190, "Removal and Installation of Steering Angle Sensor" .

3. CHECK CAN COMMUNICATIONS BETWEEN BCM AND IPDM E/R
Select “BCM” on CONSULT-II, and perform self-diagnosis for “BCM”.
Display of self-diagnosis results
NO DTC>> Replace IPDM E/R. Refer to PG-31, "Removal and
Installation of IPDM E/R" .

CAN Communication
Inspection Using CONSULT-II (Self-Diagnosis)" .
Aiming AdjustmentNKS003RH
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.
Keep all tires inflated to correct pressure.
Place vehicle on level ground.
Adjust aiming in the vertical direction by turning the adjusting screw.
1. Set the distance between the screen and the center of fog lamp
lens as shown.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is in the figure.
When performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.

Combination Switch InspectionNKS003S9
1. SYSTEM CHECK
Referring to table below, check the system to which malfunctioning switch belongs.
>> Check the system to which malfunctioning switch belongs, and then GO TO 2.
2. SYSTEM CHECK
With CONSULT-II
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. Connect CONSULT-II, and select “COMB SW” on “SELECT
TEST ITEM” screen.
2. Select “DATA MONITOR”.
3. Select “START”, and confirm that other switches in malfunction-
ing system operate normally.
Example: When the HI BEAM switch is malfunctioning, confirm
that “TURN RH”, “HEAD LAMP 1” and “TAIL LAMP SW” in Sys-
tem 5, to which the HI BEAM switch belongs, turn ON-OFF nor-
mally.
Without CONSULT-II
Operating combination switch, and confirm that other switches in malfunctioning system operate normally.
Example: When the HI BEAM switch is malfunctioning, confirm that “TURN RH”, “HEAD LAMP 1” and “TAIL
LAMP SW” in System 5, to which HI BEAM switch belongs, turn ON-OFF normally.
Check results
