If the ignition key,
immobilizer-ECU, engine-A/T-ECU is replaced or an ignition
key is
added, key IDs 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
M.U.T.-III to register the immobilizer-ECU and input the key
ID and to register the password
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.

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.
