REAR VIEW MONITOR
Revision: August 20072004 QX56
REAR VIEW MONITORPFP:28260
System DescriptionEKS007R4

When the A/T selector is in the reverse position, the display shows view to the rear of the vehicle.

Lines which indicate the vehicle clearance and distances are displayed on the monitor.
POWER SUPPLY AND GROUND
Power is supplied at all times

through 20A fuse [No. 31, located in the fuse and fusible link box]

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

through 10A fuse [No. 4, located in the fuse block (J/B)]

to rear view camera control unit terminal 2.
Ground is supplied

to rear view camera control unit terminal 3 and

to rear view camera terminal 2

through grounds B7 and B19.
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 unit

Display control unit

AV switch
REAR VIEW CAMERA OPERATION
When ignition switch is in ON or START position, power is supplied

through 10A fuse (No. 51, located in the IPDM E/R)

to back-up lamp relay terminals 1 and 3.
When A/T selector lever is in reverse position, power is supplied

through back-up lamp relay terminal 2

to TCM terminal 7.
Then, when 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 11 and 12

to the display unit terminals 4 and 15.
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 11 and 12

to the display unit terminals 4 and 15.
