DIAGNOSIS SYSTEM (AFS)

CONSULT-III Function (ADAPTIVE LIGHT)

INFOID:0000000006213915

APPLICATION ITEM

WORK SUPPORT

*: Adjusts the steering angle sensor neutral position on ABS actuator and electrical unit (control unit) side. Refer to 

BRC-64, "Work Pro-

cedure"

.

DATA MONITOR

*: The swivel angle "0

°

" (feedback value) of the swivel position sensor signal may differ from the swivel angle "0

°

" of the swivel motor

(AFS control unit command value). This causes that the swivel motor initializes the value based on the step number from the stopper. 

ACTIVE TEST

Diagnostic mode

Description

Ecu Identification

Allows confirmation of AFS control unit part number.

Self Diagnostic Result

Displays the diagnosis results judged by AFS control unit.

Work support

Sets each sensor.

Data monitor

Indicates AFS control unit input data in real time.

Active test

Provides the drive signal to the load. Checks operation.

Service item

Description

ST ANG SEN ADJUSTMENT

*

LEVELIZER ADJUSTMENT

Test item

Operation Item

Description

LOW BEAM TEST RIGHT

Origin Fast

Swivels the right headlamp to the swivel angle 0

°

 in the normal speed.

Peak Fast

Swivels the right headlamp to the swivel angle approximately 15

°

 in the nor-

mal speed.

Origin Slow

Swivels the right headlamp to the swivel angle 0

°

 in the speed at the initial-

ization.

Peak Slow

Swivels the right headlamp to the swivel angle approximately 15

°

 in the 

speed at the initialization.

LOW BEAM TEST LEFT

Origin Fast

Swivels the left headlamp to the swivel angle 0

°

 in the normal speed.

Peak Fast

Swivels the left headlamp to the swivel angle approximately 17

°

 in the nor-

mal speed.

Origin Slow

Swivels the left headlamp to the swivel angle 0

°

 in the speed at the initializa-

tion.

Peak Slow

Swivels the left headlamp to the swivel angle approximately 17

°

 in the speed 

at the initialization.

LEVELIZER TEST

Origin

Changes the aiming motor drive signal to approximately 70% of the battery 
voltage. Moves the headlamp upward and downward.

Peak

Changes the aiming motor drive signal to approximately 15% of the battery 
voltage. Moves the headlamp upward and downward.
