CAUTION / NOTICE / HINT
- NOTICE:
- ·
If the cable was disconnected from and reconnected to the negative (-) battery terminal, the estimated course lines may not be displayed on the image of the area behind the vehicle. In this case, perform "Correct the Steering Angle Neutral Point".
·Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the parking assist monitor system may be needed.
·The following malfunctions may occur if a radio and display receiver assembly from another vehicle is installed to this vehicle. Therefore, when replacing the radio and display receiver assembly, be sure to replace it with new one.
-Communication malfunction DTC is output
-Does not operate normally
- HINT:
-
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Audio and Visual System.
PROCEDURE
