COMMENTS ON TROUBLE SYMPTOM
When the screen of rear view camera is not shown
even if the selector lever <CVT, A/T> or shift lever
<M/T> is "R" (Reverse) position, the rear view cam-
era, the inside rear view mirror assembly, the wiring
harness, connectors, back-up lamp switch <M/T> or
inhibitor switch <CVT, A/T> may be defective.
NOTE: If the indicator on the inside rear view mirror
assembly is illuminated in orange but the monitor is
not displayed, this is not a malfunction as the monitor
has been set to always stay OFF.
PROBABLE CAUSES
• Damaged harness wires and connectors
• Malfunction of the back-up lamp switch <M/T>
• Malfunction of the inhibitor switch <CVT, A/T>
• Malfunction of the rear view camera
• Malfunction of the inside rear view mirror assem-

<M/T> to the "R" (Reverse) position.
(3) Check that the indicator of the inside rear view
mirror assembly illuminates in green.
Q: Is the check result normal?
YES :
Go to Step 22.
NO :
Go to Step 3.
STEP 3. Check the inside rear view mirror
assembly.
Check that the rear view screen is displayed on the
monitor of the inside rear view mirror assembly.
(1) Turn the ignition switch to the "ON" position.
(2) Move the selector lever <CVT, A/T> or shift lever
<M/T> to the "R" (Reverse) position.
(3) Press the switch of the inside rear view mirror
assembly and check that the rear view screen is
displayed.
NOTE: The illumination colour of the indicator of
the inside rear view mirror assembly changes
from orange to green.
Q: Is the check result normal?
YES :
Go to Step 22.
NO :
Go to Step 4.
STEP 4. M.U.T.-III other system diagnosis code
Check again if the diagnosis code is set to the
ETACS-ECU.
Q: Is the diagnosis code set?
YES :
Diagnose the ETACS-ECU (Refer to
GROUP 54A
− ETACS-ECU −
Troubleshooting ).
NO :
Go to Step 5.
STEP 5. M.U.T.-III other system data list
Check the input signal of ACC relay.
• Turn the ignition switch to the "ACC" position.
OK: Normal condition is displayed.
Q: Is the check result normal?
YES :
Go to Step 6.
NO :
Refer to ETACS
− Input Signal Procedure 1
"The ignition switch (ACC) signal is not sent
to the ETACS-ECU" .
STEP 6. M.U.T.-III data list
Check if ETACS-ECU related signal is set.
• Turn the ignition switch to the "ON" position.
OK: Normal condition is displayed.
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Refer to ETACS
− Inspection Procedure 2
"The ignition switch (IG1) signal is not
received" .
STEP 7. M.U.T.-III data list
Check if ETACS-ECU related signal is set.
• Turn the ignition switch to the "ON" position.
• selector lever <CVT, A/T> or shift lever <M/T> is
"R" (Reverse) position
OK: Normal condition is displayed.
Q: Is the check result normal?
YES :
Go to Step 8.
NO :
Go to Step 14.
STEP 8. Connector check: D-46 inside rear view
mirror assembly connector.
Q: Is the check result normal?
YES :
Go to Step 9.
NO :
Repair the defective connector.

STEP 9. Voltage measurement at D-46 inside rear
view mirror assembly connector.
(1) Disconnect the connector, and measure at the
wiring harness-side connector.
(2) Turn the ignition switch to the "ACC" position.
(3) Voltage between D-46 inside rear view mirror
assembly connector terminal No. 1 and the body
earth
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 11.
NO :
Go to Step 10.
STEP 10. Check the wiring harness between D-46
inside rear view mirror assembly connector
terminal No. 1 and C-315 ETACS-ECU connector
terminal No. 9
• Check the power supply lines (battery power sup-
ply) for open circuit and short circuit.
NOTE: Before the wiring harness inspection, inspect
the C-130 intermediate connector, and repair if nec-
essary.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
use Troubleshooting/inspection Service
Points
− How to Cope with Intermittent
Malfunction ).
NO :
Repair the wiring harness.
STEP 11. Resistance measurement at D-46 inside
