HOW TO REGISTER ENCRYPTED CODEM1543008100410
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 or engine-A/T-ECU 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 or engine-A/T-ECU
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
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-6.
1. Connect MUT-II to diagnosis connector (16- pin).
2. Turn the ignition switch to "ON" position.
3. At "System Select," press "YES"
