System Description [09/2012 - ]

GENERAL
1. This system has a television camera mounted on the luggage compartment door to assist the driver in parking the vehicle by displaying an image of the area behind the vehicle. The system displays the image on the accessory meter assembly.
2. This system consists of the following components:
  1. Multi-media module receiver assembly
  2. Accessory meter assembly
  3. Television camera assembly
  4. Hybrid vehicle control ECU
  5. Rear junction block ECU

FUNCTION OF COMPONENTS

The multi-media module receiver assembly controls the system by using information from the following components:

Item	Function
Multi-media module receiver assembly	Receives video signals, which contain an image of the area behind the vehicle taken with the television camera assembly. Allows operation via the remote touch when the rear view monitor screen or diagnosis screen is displayed. Performs control of the system by receiving the reverse signal from the hybrid vehicle control ECU.
Television camera assembly	Captures the view behind the vehicle and transmits the image to the accessory meter assembly. Has a color video camera that uses a Complementary Metal Oxide Semiconductor (CMOS) and wide-angle lens.
Accessory meter assembly	Receives the video signals from the multi-media module receiver assembly, and displays them on the display panel.
Hybrid vehicle control ECU	Sends the shift state signal to the rear junction block ECU through CAN communication.
Rear junction block ECU	Receives the shift state signal from hybrid vehicle control ECU through CAN communication. Sends the shift state signal to the multi-media module receiver assembly.

OPERATION EXPLANATION
1. The hybrid vehicle control ECU outputs the R position signal to the multi-media module receiver assembly when the shift lever is moved to R. After receiving the R position signal, the multi-media module receiver assembly switches to the rear view monitor system.
NOTES FOR REAR VIEW MONITOR
1. Notes for the rear view monitor.
  1. The rear view monitor may not function properly if the camera is subjected to a severe blow by any hard object.
  2. Do not "scrub" the camera because it is made of resin. Scrubbing it may scratch the cover and affect the image. Prevent organic solvents, waxes, bond removing solvents, or glass coating from adhering to the cover. If anything adheres to the cover, clean it off immediately, and wash with water.
  3. Exposing the camera to a sudden temperature change may affect proper functioning of the camera.
  4. A clear image may not appear if the camera is dirty with snow, mud, etc. In this case, wash it with water and wipe off the lens. Use a detergent to remove dirt if necessary.
2. Images are difficult to discern even in normal conditions if:
  1. Electrical devices used in the cabin area creating noise.
  2. Accessories that generate radio waves have been installed.
  3. The camera screen is frosted over (the image may be blurred or darker than normal immediately after turning the power switch on [IG]).
  4. The camera lens is dirty with snow, mud, etc.
  5. A strong beam of light, such as a sunbeam or headlight, hits the camera.
  6. It is too dark around the camera (at night etc.).
  7. The ambient temperature around the camera is either too high or too low.
  8. The vehicle is tilted at a steep angle.
