Inspection Procedure
1: Rear view camera image is not correctly displayed <Vehicles with MMCS except vehicles
with TC-SST>.
caution
Before replacing the rear view camera
or multivision display, ensure that the power supply circuit, the earth circuit, and the communication
circuit are normal (Check that the voltage is 10 V or more).
COMMENTS ON TROUBLE SYMPTOM
When the screen of rear view camera is not shown even if the shift lever <M/T> or
selector lever <CVT, A/T> is "R" (Reverse) position, the rear view
camera, multivision display, the wiring harness, connectors, back-up lamp switch <M/T> or
inhibitor switch <CVT, A/T> may be defective.
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 multivision display
DIAGNOSIS PROCEDURE
STEP 1. 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?
Diagnose the ETACS-ECU (Refer to ).
Go to Step 2.
STEP 2. M.U.T.-III data list
Check if ETACS-ECU related signal is set.
Turn the ignition switch to the "ON" position.
Item No.
Item name

OK: Normal condition is displayed.
Q.
Is the check result normal?
Go to Step 3.
Refer to .
STEP 3. 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.
STEP 7. Check the wiring harness between C-304 ETACS-ECU connector
terminal No. 2 and B-08 back-up lamp switch connector terminal No. 1 <M/T> or
B-121 inhibitor switch connector terminal No. 9 <CVT, A/T>.
Check the communication lines for open circuit and short circuit.
note
Before the wiring harness inspection, inspect the B-07 <Diesel> or A-13 <Petrol> intermediate connector,
and repair if necessary.
Q.
Is the check result normal?
YES <CVT, A/T> : Go to Step 8.
YES <M/T> : Go to Step 9.
Repair the wiring harness.
STEP 8. Check the inhibitor switch and the control cable.
Check that the inhibitor switch and the control cable are adjusted correctly (Refer to
GROUP 23A - On-vehicle Service - Inhibitor Switch and Control Cable Adjustment <CVT> or
GROUP 23C - On-vehicle Service - Inhibitor Switch and Control Cable Adjustment <A/T> ).
Q.
Is the check result normal?
Go to Step 9.
Adjust the inhibitor switch and the control cable.
STEP 9. Check the back-up lamp switch <M/T> or
inhibitor switch <CVT, A/T>.
Check the continuity of the back-up lamp switch <M/T> (Refer
to GROUP 22B - Transmission - Transmission Inspection ).
Check the continuity of the inhibitor switch <CVT, A/T> (Refer
to GROUP 23A - On-vehicle Service - Inhibitor Switch Continuity Check <CVT> or
GROUP 23C - On-vehicle Service - Inhibitor Switch Check <A/T> ).
Q.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How
to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent
Malfunctions ).
Replace the back-up lamp switch <M/T> or inhibitor
switch <CVT, A/T>.
STEP 10. Confirmation in MMCS service mode.
(1)Display the VEHICLE SIGNAL CHECK screen (Refer to ).
(2)Move the selector lever <CVT, A/T> or
shift lever <M/T> to the "R" (Reverse) position and check whether
"ON" is displayed.
STEP 12. Check the wiring harness between C-311 ETACS-ECU connector
terminal No. 2 and C-10 multivision display connector terminal No. 24.
Check the communication lines for open circuit and short circuit.
note
Before the wiring harness inspection, inspect the C-21 and C-36 intermediate connector
,and repair if necessary.
Q.
Is the check result normal?
Go to step 13.
Repair the wiring harness.
STEP 13. Confirmation in MMCS service mode.
Perform "Network/Connect Line Check" in the MMCS service mode
to check that the communication and wire connection with the rear view camera are OK (Refer
to ).
note
The rear view camera is shown as "rear camera" on the "Network/Connect Line Check"
in the service mode of MMCS.
Q.
Is the check result normal?
Go to Step 16.
Go to Step 14.
STEP 14. Connector check: F-25 rear view camera connector and C-06
multivision display connector.
Q.
Is the check result normal?
Go to Step 15.
Repair the defective connector.
STEP 15. Check the wiring harness between F-25 rear view camera connector
terminal No. 6, 2, 5, 4 and C-06 multivision display connector terminal No. 83, 81, 82, 86.
Check the communication lines for open circuit and short circuit.
note
Before the wiring harness inspection, inspect the C-21, C-22 and D-09 intermediate connectors,
and repair if necessary.
Q.
Is the check result normal?
Go to Step 16.
Repair the wiring harness.
STEP 16. Confirmation in MMCS service mode.
(1)Display the VEHICLE SIGNAL CHECK screen (Refer to ).
(2)Move the selector lever <CVT, A/T> or
shift lever <M/T> to the "R" (Reverse) position and check whether
"ON" is displayed.
Q.
Is the check result normal?
Go to Step 17.
Replace the multivision display.
STEP 17. Trouble symptom recheck.
Check that the display of rear view camera is shown normally.
Q.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How
to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent
Malfunctions ).
Replace the rear view camera temporarily and go to Step 18.
