Toyota Sienna Service Manual: System description
1. GENERAL
- 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 radio and navigation assembly.
- This system consists of the following components:
- Radio and navigation assembly
- Television camera assembly
- This system is equipped with a self-diagnosis
system, which is operated on a dedicated window
that appears on the display panel, just as in the
navigation system.
2. FUNCTION OF COMPONENTS
- The radio and navigation assembly controls the
system by using information from the following
components:
Item |
Function |
Television Camera Assembly |
- Mounted on the luggage compartment door to transmit the rear
view of the vehicle to the radio and navigation assembly.
- A color video camera that uses a CCD (Charge Coupled Device)
and a wide-angle lens
|
Radio and Navigation Assembly |
- Transmits video signals, which contain an image of the area
behind the vehicle taken with the television camera assembly.
- Radio and navigation assembly effects control of the
system by
receiving the shift position signal from park/neutral position
switch.
- Displays the rear view monitor image on the display panel.
|
Park/Neutral Position Switch |
Transmits a reverse shift position signal to the radio and
navigation
assembly. |
3. OPERATION EXPLANATION
- The radio and navigation assembly receives the R
position signal from the park / neutral position switch
when the shift lever is moved to the R position. After
receiving the R position signal, the radio and
navigation assembly switches from the navigation
system to the rear view monitor system.
4. NOTES FOR REAR VIEW MONITOR
- Notes for the rear view monitor.
- The rear view monitor may not function properly
if subjected to a severe blow by any hard object.
- Do not "scrub" the cover part of the camera
(resin made). 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. Clean it off
immediately, and wash with water.
- Exposing the camera to a sudden temperature
change may affect proper functioning of the
camera.
- 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.
- Images are difficult to discern even in normal
conditions if:
- Camera screen is frosted over (the image
immediately after turning the ignition switch to
the on position may be blurred or darker than
normal).
- 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.
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.
