COMMENTS ON TROUBLE SYMPTOM
The heated door mirrors should works for
approximately 11 minutes when the rear defogger
switch is turned on. If the mirror heater does not work
for the specified period, the defogger relay circuit
(heated door mirror power supply circuit) may be
defective.
Possible causes
•Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
STEP 1. Check the rear window defogger.
Check that the rear window defogger system should
work normally.
Q: Is the check result normal?
YES :
Go to Step 2.
NO : Troubleshoot the rear window defogger
(Refer to GROUP 55,
TroubleshootingP.55-42).
STEP 2. Connector check: C-212 junction block
connector
Q: Is the check result normal?
YES :
Intermittent malfunction (Refer to GROUP
00 − How to Cope with Intermittent
Malfunction P.00-5).
NO : Repair the defective connector.

SYMPTOM PROCEDURES
INSPECTION PROCEDURE 1: Communication with MUT-II/III is Impossible.
TECHNICAL DESCRIPTION (COMMENT)
•This malfunction may be caused by a defective
immobilizer-ECU, engine-ECU or
engine-A/T-ECU , or a defect in the
communication line between the
immobilizer-ECU and engine-ECU or
engine-A/T-ECU . If this malfunction
appears when the MPI system and MUT-II/III can
communicate each other, MPI system diagnosis
code No.P0513 will reset.•If the MPI system is normal, the engine control
relay can be determined as normal. In addition, if
the MPI system and MUT-II/III can communicate
each other, the circuits between the diagnosis
connector and the engine-ECU or
engine-A/T-ECU can determined as
normal.
NOTE: If this malfunction appears, MPI system
diagnosis code No.P0513 will be set.

•Malfunction of the immobilizer-ECU.
•Malfunction of the engine-ECU or
engine-A/T-ECU .
•The wiring harness or connectors may have
loose, corroded, or damaged terminals, or
terminals pushed back in the connector.
DIAGNOSIS PROCEDURE
STEP 1. Check if MUT-II/III can communicate with
the MPI system and if an MPI system diagnosis
code other than P0513 is set.
Q: Can MUT-II/III communicate with the MPI system?
Is an MPI system diagnosis code other than P0513
set?
YES :
Go to Step 2.
NO : Refer to GROUP 13A, MPI Diagnosis
P.13A-15, GROUP 13B, MPI Diagnosis
P.13B-15.
STEP 2. Voltage measurement at
immobilizer-ECU connector C-202-1.
(1) Disconnect immobilizer-ECU connector C-202-1.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 1 and
earth.
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 5.
NO : Go to Step 3.
STEP 3. Connector check: Immobilizer-ECU
connector C-202-1 and engine control relay
connector B-16X
Q: Are immobilizer-ECU connector C-202-1 and
engine control relay connector B-16X in good
condition?
YES :
Go to Step 4.
NO : Repair or replace the damaged
component(s). Confirm that MUT-II/III
communicates normally.AC303806

STEP 4. Check the harness wires between
immobilizer-ECU connector C-202-1 (terminal 1)
and engine control relay connector B-16X
(terminal 4).
NOTE:
Prior to the wiring harness inspection, check
intermediate connector C-13 ,
C-137 , joint connector C-12
, C-134 and
key reminder switch connector C-202, and repair if
necessary.
Q: Are the harness wires between immobilizer-ECU
connector C-202-1 (terminal 1) and engine control
relay connector B-16X (terminal 4) in good
condition?
YES :
There is no action to be taken.
NO : Replace damaged component(s). Confirm
that MUT-II/III communicates normally.

5. Enter the vehicles password (secret code) on the
"Transponder ID addition" screen, and then click
the check mark icon.
6. If an additional registration is made successfully,
the screen will ask if another key is registered or
not. If the third ignition key is registered, remove
the key, which has been registered. Then insert
the third key within five seconds, and then turn it
to the ON position.
7. Register the additional ignition key according to
step 6 above. The number of the registered
ignition keys are shown on "The number of
registered key" screen.
NOTE: A maximum of eight different keys can be
registered.
8. This completes the registration operation. Turn
the ignition switch "LOCK" (OFF) and leave it off
for approximately ten seconds.
9. Check that the engine can be started with each of
the ignition keys.
10.Check that the immobilizer system diagnosis
code and MPI system diagnosis code did not set.
11.If not diagnosis code is shown, terminate the
MUT-III.
12.Turn the ignition switch to "LOCK" (OFF) position.
13.Disconnect MUT-III.Registration of additional key(s) without
using the MUT-III
If the MUT-III is not available, new key(s) can be
registered by operating two keys which have been
registered to the vehicle (A maximum of eight keys
can be registered to one vehicle). Follow the
procedure below to register new key(s) to the
vehicle.
NOTE: The registered key is the key that allows you
to start the engine.
1. Turn "ON" the ignition switch by using the first
registered key (key A), and wait for five seconds.
2. Remove the first registered key (key A).
3. Insert the second registered ignition key (key B),
and turn it to the ON position.
4. The immobilizer-ECU identifies the new key to
accept or reject it, and operates the immobilizer
indicator (See the table below).
5. If a new ignition key is registered further, repeat
steps 1 to 7 above.
A maximum of eight ignition keys can be registered
to one vehicle (If you attempt to register the ninth
key, the immobilizer-ECU rejects the key). If any of
the following conditions are satisfied, the additional
key registration mode will terminate:
•The ignition switch has been on for more than 30
seconds.
•After the ignition key has been turned to the
"LOCK" (OFF), the engine control relay is turned
off.
•The MUT-III has started communicating with
vehicle systems.
6. After the registration mode has terminated, the
additionally registered key(s) should allow you to
start the engine.
