Trouble phenomenon Possible cause
Indication is irregular for the speedometer and odo/trip meter. Refer to DI-17, "
Vehicle Speed Signal Inspection" .
Tachometer indication is malfunction. Refer to DI-18, "
Engine Speed Signal Inspection" .
Water temperature gauge indication is malfunction. Refer to DI-19, "
Water Temperature Signal Inspection" .
Fuel gauge indication is malfunction. Refer to DI-20, "
Fuel Level Sensor Signal Inspection 1" .
Low-fuel warning lamp indication is irregular. Refer to DI-21, "
Fuel Level Sensor Signal Inspection 2" .
Indications are irregular for more than one gauge. Replace combination meter.
A/T position indicator is malfunction. Refer to DI-53, "
A/T Indicator Is Malfunction" .
Illumination control does not operate.Refer to DI-24, "
Odo/Trip Meter and Illumination Control Switch
Inspection" .
Displayed item [Code] Inspection contents Possible cause
CAN COMM CIRC [U1000] Inspect the CAN communication.Refer to DI-22, "
CAN Communication System Inspection" .
CAUTION:
Even when there is no malfunction on CAN communica-
tion system, malfunction may be misinterpreted when bat-
tery has low voltage (when maintaining 7-8V for about 2
seconds) or 10A fuse [No. 19, located in the fuse block (J/
B)] is disconnected.

SELF-DIAGNOSTIC RESULTS
Operation Procedure
1. Touch “SELF-DIAG RESULTS” on “SELECT DIAG MODE” screen.
2. Self-diagnosis results are displayed.
Display Item List
“TIME” indicates the condition of the self-diagnosis results judged by each signal input.

Normal: In case of operating properly at the present in spite of having malfunction in the past, then “TIME”
indicates “1-63”.

Malfunction: Soon after detecting malfunctions by self-diagnoses or current malfunction, “0” is indicated.
After returning to normal condition, every time when ignition switch is turned to “OFF” from “ON”, time will be
added like “1”→“2”→“3”···“63”, and when the key operation is performed 64 times, the result of the self-diag-
noses will be erased. And if any malfunction is detected again, “0” will be indicated.
CAUTION:
“TIME” keeps showing “0” after returning to normal condition only in the case that malfunction his-
tory of “CAN COMM CIRC [U1000]” remains because of low tire pressure warning control unit, display
control unit (with NAVI) or display unit (without NAVI) malfunction.
DATA MONITOR
Operation Procedure
1. Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.
2. Touch either “MAIN SIGNALS” or “SELECTION FROM MENU” on the “DATA MONITOR” screen.
3. When “SELECTION FROM MENU” is selected, touch individual items to be monitored. When “MAIN SIG-
NALS” is selected, main items will be monitored.
SKIA4956E
CONSULT-ll display Malfunction is detected when...
CAN COMM CIRC [U1000]Malfunction is detected in CAN communication.
CAUTION:
Even when there is no malfunction on CAN communication system, malfunction may be
misinterpreted when battery has low voltage (when maintaining 7-8V for about 2 seconds)
or 10A fuse [No. 19, located in the fuse block (J/B)] is disconnected.
METER COMM CIRC [B2202]Malfunction is detected in communication of between combination meter and unified meter and
A/C amp.
VEHICLE SPEED CIRC [B2205]When an erroneous speed signal is input for 1 seconds.
CAUTION:
Even when there is no malfunction on speed signal system, malfunction may be misinter-
preted when battery has low voltage (when maintaining 7-8V for about 2 seconds).
MAIN SIGNALS Monitors main signals.
SELECTION FROM MENU Selects and monitors individual signal.

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
