INSPECTION PROCEDURE 3: Engine does not Start (Cranking but no Initial Combustion).

TECHNICAL DESCRIPTION (COMMENT)
If the fuel injectors are not operating, there might be
a problem with the MPI system in addition to a
malfunction of the immobilizer system. It is normal for
this to occur if an attempt is made to start the engine
using a key that has not been properly registered.

TROUBLESHOOTING HINTS

•

Malfunction of MPI system

•

Malfunction of immobilizer-ECU

DIAGNOSIS PROCEDURE

STEP 1. Check the system voltage.

Measure the system voltage during cranking.

Q: Is the voltage 8 volts or more?

YES :

Go to Step 2.

NO :

Check the battery. Refer to

P.54A-4

. The

engine should start.

STEP 2. Check the immobilizer system diagnosis
code and MPI system diagnosis code.

Q: Which diagnosis code resets, the immobilizer

system diagnosis code or the MPI system
diagnosis code?

Immobilizer system diagnosis code is set :

Refer

to

P.54A-9

.

MPI system diagnosis code is set :

Refer to

GROUP 13A, Troubleshooting

P.13A-16

or

GROUP 13B, Troubleshooting

P.13B-20

.

No diagnosis code is set :

Go to Step 3.

STEP 3. Check the starting system.

Q: Does the engine start?

YES :

Go to Step 4.

NO :

Refer to GROUP 13A, Troubleshooting

−

Symptom Chart

P.13A-185

or GROUP 13B,

Symptom Chart

P.13B-281

. If the malfunction is not

resolved, replace the immobilizer-ECU.
Then register the password (secret code)
and encrypted code. (Refer to

P.54A-24

.)

The engine should start.

STEP 4. Retest the system

Q: Is the malfunction eliminated?

YES :

The procedure is complete. (If no

malfunction are found in all steps, an
intermittent malfunction is suspected. Refer
to GROUP 00, How to Use
Troubleshooting/Inspection Service
Points-How to Cope with Intermittent
Malfunction

P.00-6

.)

NO :

Replace the immobilizer-ECU.

HOW TO REGISTER ENCRYPTED CODE

M1543008100454

CAUTION

Because registering the encrypted codes is done
after all previously-registered codes have been
erased, you should keep all of the ignition keys
that have already been registered accessible.
If the ignition key, Immobilizer-ECU, engine-ECU
<M/T> or engine-A/T-ECU <A/T> is replaced or an
ignition key is added, encrypted codes of all the
ignition keys must be registered. (A maximum of
eight different ignition key can be registered.)
Moreover, when the immobilizer-ECU has been
replaced, you will need to use MUT-II/III to register
the immobilizer-ECU and input the vehicle secret
code and to register the password (secret code) that

the owner specifies into the immobilizer-ECU. If an
attempt is made to start the engine with an
unregistered ignition key, cranking occurs, but fuel
supply is cut off to disable the engine. In
approximately.
NOTE: Engine-ECU <M/T> or engine-A/T-ECU
<A/T> has an encrypted code for immobilizer-ECU,
and the encrypted code is registered in the
immobilizer-ECU and ignition key.

POINTS TO NOTE DURING OPERATION

If none of the functions can be used, check the
diagnosis codes, and after carrying out any
necessary repairs, repeat the operation. If an
incorrect password is input ten times in a row, the
immobilizer-ECU judges that an unauthorized
operation is being attempted. Start-prevention mode
will be set, and engine operation will stop and all
special functions will be disabled. If the ignition
switch is turned to "ON" position, "Unauthorized
operation, start-prevention mode" will be cancelled.

KEY ID (ENCRYPTED CODE)
REGISTRATION <MUT-II>

All ignition keys can be registered with MUT-II.
Additional ignition keys can be registered with
MUT-II.
Registration with the MUT-II

CAUTION

To prevent damage to MUT-II, always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting MUT-II.
NOTE:

.

•

Using the key ID register function will cause all
key IDs that have been previously registered in
the immobilizer-ECU to be erased. All keys need
to be registered. Those which have been
registered before should be on hand before using
this function.

•

If registering more than one key, do not
disconnect MUT-II halfway through the
registration process.

•

After registering key IDs, check that the engine
can be started using all of the keys that have
been registered. If the engine will not start, refer
to Immobilizer System Diagnosis

P.54A-8

.

1. Connect MUT-II to diagnosis connector (16- pin).
2. Turn the ignition switch to "ON" position.

3. At "System Select," press "YES"

4. Select "Immobilizer," press "YES".

5. Select "Special Func", press "YES". If diagnosis

code No.11 exists, "Can't execute" will be
displayed. Check for diagnosis code No.11 (Refer
to

P.54A-9

.)

6. Select "key ID register", press "YES".

7. Input the password. Use the "UP" and "DOWN"

keys to change the current password digit to a
value between 0 and 9. Use the "LEFT" and
"RIGHT" keys to move to a different password
digit. Press the "YES" key to accept the password.
If an incorrect password is input five times in a
row, this screen is displayed and the
immobilizer-ECU switches to unauthorized
operation, start-prevention mode.
NOTE: Four separate digits must be input to
make up the password.

8. Press the "YES" key to start key ID registration.

9. This will be displayed when the key ID registration

is successful. If an error occurs during key ID
registration, the message "Can't execute" will be
displayed. If the key has already been registered,
"Key ID has been registered" will be displayed.

10.The number of keys currently registered will be

displayed. To register an additional key, replace
the ignition key with the next key to be registered
within five seconds and then press the "YES" key.
Key ID registration screen will be displayed, then
register another key. If key ID registration is
complete, press the "NO" key.
NOTE: A maximum of eight different keys can be
registered.

11.This completes the registration operation. Turn

the ignition switch "LOCK" (OFF) and leave it off
for approximately ten seconds.

12.Check that the engine can be started with each of

the ignition keys.

13.Check that the immobilizer system diagnosis

code and MPI system diagnosis code did not set.

14.Turn the ignition switch to "LOCK" (OFF) position.
15.Disconnect MUT-II.
