Auto Aiming Operation Check (Function Test)

WARNING: This page is about a different car, the 2008 Infiniti M45 and 2008 Infiniti M35. However, it is still accessible from the selected car via links, so may be relevant.

CHECK AIMING MOTOR

CONSULT-III ACTIVE TEST

Start engine and turn lighting switch to 2ND position.
Select "LEVELIZER TEST" of ADAPTIVE LIGHT active test item.
Touch "ORIGIN" and "PEAK" screen.

Make sure of auto aiming operation.

LIGHT AXIS RANGE REFERENCE VALUE

TEST ITEM	ORIGIN	PEAK (Reference value)	Light axis range at 10 m (394.7 in) off (Reference value)
LEVELIZER TEST	Light axis angle 0°	Light axis angle approx. 2.5°	Approx. 450 mm (17.7 in)

OK or NG

OK: GO TO 2.

NG:

When interference or poor figment is found, perform aiming adjustment. Refer to "AIMING ADJUSTMENT ". If it is normal, replace headlamp. Refer to "REMOVAL AND INSTALLATION OF FRONT COMBINATION LAMP ".
When the operation range is irregular, perform aiming adjustment. Refer to "AIMING ADJUSTMENT ". If it is normal, GO TO 4.

PERFORM STATE LEVELIZER ADJUSTMENT 1

CONSULT-III DATA MONITOR

Check "LEV ACTR VLTG" in "Data Monitor" with unloaded vehicle position. (Remove all loads in driver, passenger and trunk rooms.)

TEST ITEM CHART

TEST ITEM	Unloaded vehicle position
LEV ACTR VLTG	Approx. 70%

OK or NG

OK: GO TO 3.

NG: Perform LEVELIZER ADJUSTMENT. Refer to "WORK SUPPORT (LEVELIZER ADJUSTMENT) ".

PERFORM STATE LEVELIZER ADJUSTMENT 2
Check if "LEV ACTR VLTG" changes approx. 3 seconds after lowering vehicle height as low as approx. --0.5V from the value of "HI SEN OTP RR" in "Data Monitor" at unloaded vehicle position. (Remove all loads in driver, passenger and trunk rooms.)

OK or NG

OK: GO TO 4.

NG: Perform LEVELIZER ADJUSTMENT. Refer to "WORK SUPPORT (LEVELIZER ADJUSTMENT) ".

CHECK HEIGHT SENSOR SIGNAL AND AIMING MOTOR DRIVE SIGNAL

CONSULT-III DATA MONITOR

Remove height sensor link bracket mounting nuts (rear stabilizer side). For details, refer to "REMOVAL AND INSTALLATION OF HEIGHT SENSOR ". Change sensor angle from the basic point of sensor angle 0° (standard position) and check "HI SEN OTP RR" and "LEV ACTR VLTG" of "Data Monitor".

SENSOR ANGLE REFERENCE CHART

	Sensor angle	Vehicle height
A	Approx. --103° (Link stopper angle)	Low side
B	0° (Standard position)	Unloaded vehicle position
C	Approx. 46° (Link stopper angle)	High side

OK or NG

OK: Auto aiming operation function is normal.

NG:

When approx. 4.5 V or 0.5 V is not displayed on "HI SEN OTP RR" screen with sensor angle approx. 45° or --45°, check connector for connection, bend and loose fit. If it is normal, replace height sensor. Refer to "REMOVAL AND INSTALLATION OF HEIGHT SENSOR ".
When "HI SEN OTP RR" value is normal but "LEV ACTR VLTG" value differs from maximum/minimum angle of auto aiming operation, replace AFS control unit. Refer to "REMOVAL AND INSTALLATION OF AFS CONTROL UNIT ".
When "LEV ACTR VLTG" value is normal but operation range is irregular, check aiming motor system circuit. Refer to "AUTO AIMING DOES NOT OPERATE (CHECK AIMING MOTOR SYSTEM CIRCUIT) ".
