INSPECTION PROCEDURE FOR DIAGNOSIS CODES
Code No. 11 Transponder communication systemProbable cause

The ID code of the transponder is not sent to the immobilizer-ECU immediately
after the ignition switch is turned to the ON position.

When starting the engine, one ignition key’s ID code interferes with another ignition
key’s code.

Inspection Procedure 2
ID code cannot be registered using the MUT-II.
Probable cause
The cause is probably that there is no ID code registered in the immobilizer-ECU,
or there is a malfunction of the immobilizer-ECU.

Inspection Procedure 3
Engine does not start (cranking but no initial combustion).
Probable cause
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.

ID CODE REGISTRATION METHOD
If using an ignition key that has just been newly purchased,
or if the immobilizer-ECU has been replaced, you will need
to register the ID codes for each ignition key being used
into the immobilizer-ECU. (A maximum of eight different ID
codes can be registered.)
Moreover, when the immobilizer-ECU has been replaced, you
will need to use the MUT-II to register the password that
the user specifies into the immobilizer-ECU. (Refer to the
MUT-II instruction manual for instructions on using the MUT-II.)
Caution
If registering of the ID codes is carried out all
previously-registered codes will be erased. Accordingly,
you should have ready all of the ignition keys that have
already been registered.
1. Connect the MUT-II to the diagnosis connector.
Caution
Turn the ignition switch off before connecting or
disconnecting the MUT-II.
2. Check that the diagnosis code No.54 is not displayed
for MPI system. If the code is displayed, carry out
troubleshooting before proceeding to the next step. (Refer
to GROUP 13A – Troubleshooting).
3. Use the ignition key that is to be registered to turn the
ignition switch to the ON position.
4. Use the MUT-II to register the ID code. If you are
registering two or more codes, use the next key to be
registered to turn the ignition switch to the ON position
without disconnecting the MUT-II.
5. Disconnect the MUT-II. This completes the registration
operation.
6. Check that the engine can be started by each one of
the ignition keys.
7. Check that the diagnosis code No.54 is not displayed
for MPI system. If the code is displayed, erase it. (Refer
to GROUP 13A – Troubleshooting).

DIAGNOSIS FUNCTION
INPUT SIGNAL INSPECTION POINTS
Refer to Group 00 – How to Use Troubleshooting / Inspection Service Points.
The lighting monitor buzzer does not sound even when
the ignition key is removed with the tail lamps or
headlamps ON and the driver’s side door open. [However,
the key reminder warning buzzer sounds when inserting
the key into the ignition key cylinder.
Probable cause
The cause is probably a malfunction of the lighting switch input circuit system or
a malfunction of ETACS-ECU or buzzer ECU. When the key reminder warning buzzer
is sounding, the lighting monitor warning buzzer does not sound even if the tail lamps
or headlamps are lit.
