WORK SUPPORT (STEERING ANGLE SENSOR ADJUSTMENT)
Work Support Item List
CAUTION:
Never use this function but on VDC side.
Notes on Steering Angle Sensor (Neutral Point) Adjustment

Be sure to adjust steering angle sensor neutral point before driving if any of the following has been
removed/installed or replaced: Steering angle sensor; Steering system part, Suspension system part.

On vehicle with VDC, perform steering angle sensor neutral point adjustment only on VDC side. Never
perform the adjustment on ADAPTIVE LIGHT side as this may lead to VDC malfunctions. If the adjust-
ment has been performed on AFS side, readjust on VDC side. For steering angle sensor neutral point
adjustment procedures on VDC side, refer to BRC-6, "
Adjustment of Steering Angle Sensor Neutral Posi-
tion" in “ON-VEHICLE SERVICE”.

When replaced steering angle sensor, AFS control unit detects “DTC B2515 ST ANG SEN SIG”. Delete
the malfunction history after adjust steering angle sensor on VDC side.

Steering angle sensor neutral point adjustment should be performed using CONSULT-II. (The adjustment
will not be possible without CONSULT-II.)
Operation Procedure
Refer to BRC-6, "Adjustment of Steering Angle Sensor Neutral Position" .

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.
