PARK ASSIST / MONITORING  TOYOTA PARKING ASSIST-SENSOR SYSTEM(w/ Parking Support Brake System)  CALIBRATION  

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during TOYOTA parking assist-sensor system removal/installation are shown below.

HINT:

When the bumper is removed and installed, or when the sensor is removed and installed, the registration is not required. However, if the body part is damaged or deformed due to an accident or contact, etc., and the body part is modified, measurement and registration are required.
