REAR VIEW MONITORPFP:28260
System DescriptionAKS0068D

The rear view monitor is equipped to check the rearward of the vehicle with display when A/T selector
lever is in reverse position.

The lines of vehicle sides and the distance from the rear end of the vehicle are provided on display as a
guide. It allows the driver to know the distance between the vehicle and a rearward object, and the width
of the vehicle much easier.
POWER SUPPLY AND GROUND
Power is supplied at all time

through 10A fuse [No. 19, located in fuse block (J/B)]

to rear view camera control unit terminal 1.
When ignition switch is in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to rear view camera control unit terminal 2.
When ignition switch is in ON or START position, power is supplied

through 10A fuse (No. 83, located in IPDM E/R)

to back-up lamp relay terminals 2 and 3.
Ground is supplied

to rear view camera control unit terminal 3

through grounds M35, M45 and M85.
AV COMMUNICATION LINE
Rear view camera control unit is connected to the following units with AV communication line. Each unit trans-
mits/receives data with AV communication line.

NAVI control unit

Display

Display control unit

A/C and AV switch
REAR VIEW CAMERA OPERATION
When A/T selector lever is reverse position, power is supplied

through back-up lamp relay terminal 1

to TCM terminal 7.
Then back-up lamp relay is energized,

from back-up lamp relay terminal 5

to rear view camera control unit terminal 4.
Then, rear view camera control unit is sent camera ON signal

through rear view camera control unit terminal 8

to rear view camera terminal 1.
An image taken by rear view camera is sent

through rear view camera terminals 3 and 4

to rear view camera control unit terminals 10 and 9.
Then an image is sent

through rear view camera control unit terminals 12 and 14

to the display terminals 15 and 16.
An image of rear view will be projected on the display.
Side Distance Guideline
When A/T selector lever is in reverse position, rear view camera control unit is sent rear view camera guideline
image

through rear view camera control unit terminals 12 and 14
