INSPECTION PROCEDURE

NOTICE:

1. 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" (LandCruiser RM0000035DE05YX.html).
   
2. 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 (LandCruiser RM0000035DD06QX.html).
   

HINT:

Images may be unclear even in normal conditions if:

1. Electrical devices are used in the cabin (noise may occur in the image).
   
2. Accessories that generate radio waves have been installed (noise may occur in the image).
   
3. The outer mirror switch assembly is operated (noise may occur in the image).
   
4. The navigation receiver assembly*1 or radio and display receiver assembly*2 is cold (the image immediately after turning the engine switch on (IG) may be blurred or darker than normal).
   
1. *1: for Navigation Receiver Type
   
2. *2: for Radio and Display Type
