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.
