    NOTE
    After any of the following conditions, check the adjustment of the steering angle sensor neutral position before driving the vehicle:


    CAUTION
    To adjust the neutral position of steering angle sensor, make sure to use the CONSULT-II. (Adjustment cannot be done without CONSULT-II.)



    Replacing ABS actuator and electric unit (control unit)
     
    Removing/installing steering angle sensor
     
    Removing/installing steering components
     
    Removing/installing suspension components
