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).
