SYSTEM DESCRIPTION

Item

GENERAL
(a) To assist the driver with parking the vehicle by
displaying an image of the area behind the vehicle,
this system has a television camera mounted on the
luggage compartment door. The system displays
the image on the multi-display.
(b) This system consists of the following components:
(1) Multi-display
(2) Television camera
(c) This system is equipped with a self-diagnosis
system, which is operated on a designated window
that appears on the display panel, just as in the
navigation system.
FUNCTION OF COMPONENTS
(a) The multi-display controls the system by using
information from the following components:
Function
•

Television Camera Assembly

•
•
•

Multi-display

•
BK/UP LP Relay

Mounted on luggage compartment door to transmit an image of
area behind vehicle to multi-display.
Color video camera that uses CCD (Charge Coupled Device) and
wide-angle lens.
Receives video signals, which contain an image of area behind
vehicle taken with television camera assembly.
Multi-display effects control of system by receiving shift position
signal from BK/UP LP relay.
Displays rear view monitor image on display panel.

Transmits a reverse shift position signal to multi-display.

3.

4.

OPERATION EXPLANATION
(a) The BK/UP LP relay sends an R position signal to
the multi-display when the shift lever is moved to the
R position. After receiving the R position signal, the
multi-display switches from the navigation system to
the rear view monitor system.
NOTES FOR REAR VIEW MONITOR
(a) Notes for the rear view monitor.
(1) The rear view monitor may not function properly
if subjected to a severe impact by any hard
object.
(2) Do not "scrub" the lens of 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 the lens 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 that case, wash it
with water and wipe off the lens. Use a detergent
to remove dirt if necessary.

(b) Images are difficult to discern even in normal
conditions if:
(1) The camera lens is frosted over (the image
immediately after turning the power switch ON
(IG) may be blurred or darker than normal).
(2) A strong beam of light, such as a sunbeam or
headlight, hits the camera.
(3) It is too dark around the camera (at night, etc.).
(4) The ambient temperature around the camera is
either too high or too low.
HINT:
When a strong light, such as a sunbeam
reflected off the vehicle's body, hits the camera,
the image may be blurred. This is called the
"SMEAR" phenomenon, peculiar to the CCD
camera.

HINT:
Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms are
listed in order of probability in the "Suspected area" column of
the table. Check each symptom by checking the suspected
areas in the order they are listed. Replace parts as
necessary.
Symptom

When shift lever is in R position, rear view monitor
image is not displayed (Screen is not black).

When shift lever is in R position, rear view monitor
image is not displayed (Screen is black).

When shift lever is not in R position, rear view monitor
image is displayed.
