Title: PARK ASSIST / MONITORING: PANORAMIC VIEW MONITOR SYSTEM (for Gasoline Model): Image from Camera for Panoramic View Monitor is Abnormal; 2019 - 2022 MY RAV4 [11/2018 - 10/2022]

Image from Camera for Panoramic View Monitor is Abnormal

DESCRIPTION

The display signal from each television camera is transmitted to the radio and display receiver assembly via the parking assist ECU.

WIRING DIAGRAM

CAUTION / NOTICE / HINT

NOTICE:

  • When "!" mark is displayed on the parking assist ECU after the battery terminal has been disconnected, correct the steering angle neutral point.

  • 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 a new one.
    • Communication malfunction DTC is output
    • Does not operate normally

HINT:

Images may be unclear even in normal conditions if:

  • Electrical devices are used in the cabin (noise may occur in the image).
  • The camera lens is frosted over (the image immediately after turning the engine switch on (IG) may be blurred or darker than normal).
  • The camera lens is dirty with snow, mud, etc.
  • A strong beam of light, such as a sunbeam or headlight, hits the camera.
  • It is too dark around the camera (at night, etc.).
  • The ambient temperature around the camera is either too high or too low.
  • The vehicle is tilted at a steep angle.
  • The television camera assembly lens is scratched.
  • The television camera assembly lens has drops of water on it or the humidity is high.
  • When the camera is used under fluorescent lights, sodium lights, or mercury lights, etc., the lights and the illuminated area may appear to flicker.
