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" in BRC section.
WORK SUPPORT (LEVELIZER ADJUSTMENT)
Work Support Item List
Operation Procedure
1. Set the vehicle in unload condition. (Removal all loads in driver, passenger and trunk rooms.)
2. Touch “ADAPTIVE LIGHT” on “SELECT SYSTEM” screen.
3. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
4. Touch “LEVELIZER ADJUSTMENT”.
5. Touch “START”.
6. “ADJUSTMENT COMPLETE” will be displayed.
CAUTION:
When “CAN NOT BE TESTED” is displayed, AFS control unit stops levelizer adjustment as it
detected the change of height sensor signal. AFS control unit detects “DTC B2519 LEVELIZER
CALIB”.
Turn ignition switch OFF not to change the vehicle height. Then turn ignition switch ON and per-
form levelizer adjustment again.
When “ADJUSTMENT COMPLETE” is displayed, and “NO DTC IS DETECTED” is displayed on
self-diagnosis results, levelizer adjustment is completed.
When “ADJUSTMENT COMPLETE” is displayed, and “B2514 HI SEN UNUSUAL” is displayed on
self-diagnosis results, refer to LT-174, "
DTC B2514 HI SEN UNUSUAL RR" .

SELF-DIAG RESULTS
Operation Procedure
1. Touch “ADAPTIVE LIGHT” on “SELECT SYSTEM” screen.
2. Touch “SELF-DIAG RESULTS” on the “SELECT DIAG MODE” screen.
3. Check display content in self-diagnostic results.
CAUTION:
DTC B2503 and B2504 cannot be detected before the swivel operation. Thus, perform swivel operation
first, and then check the display in self-diagnostic results.
