Notes on Steering Angle Sensor (Neutral Point) Adjustment

Be sure to adjust steering angle sensor to the neutral point before driving if any of the followings is
removed/installed or replaced: AFS control unit; Steering angle sensor; Steering system part, Suspension
system part.

Steering angle sensor neutral point adjustment should be performed by using CONSULT-II. (The adjust-
ment is not operative without CONSULT-II.)
Operation Procedure (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 adjustment has been performed on AFS
side, readjust on VDC side. For steering angle sensor neutral point adjustment procedures on VDC side, refer
to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" in “ON-VEHICLE SERVICE”.
