Ignition Switch and Immobilizer System

ENCRYPTED 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 encrypted codes for each ignition key being
used into the immobilizer-ECU. (A maximum of eight different
encrypted 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
Because registering of the encrypted codes is carried
out after all previously-registered codes have been
erased, 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 to LOCK (OFF) position before
connecting or disconnecting the MUT-II.
2. Check that diagnosis code No. P1160 is not being
generated by the each engine-ECU. If it is being generated
check according to the Troubleshooting Procedures.
(Refer to GROUP 13A - Troubleshooting.)
3
Use the ignition key that is to be registered to turn on
the ignition switch.
4. Use the MUT-II to register the encrypted code. If you
are registering two or more codes, use the next key to
the registered to turn on the ignition switch without
disconnecting the MUT-II.
5. Turn off the ignition switch.
6. Check that the engine can be started with each of the
ignition keys.
7. Check the diagnosis output from the each engine-ECU,
and erase code No. P1160 if it appears. (Refer to GROUP
13A - Troubleshooting.)
8. Disconnect the MUT-II. This completes the registration
operation.
