ON-VEHICLE SERVICE

ENCRYPTED CODE REGISTRATION METHOD

M1543008100476

Required Special Tools:

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B (Vehicles without

CAN communication system)

CAUTION

Because registeing 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 regis-
tered accessible.
If the ignition key, immobilizer-ECU or PCM 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 scan tool MB991958 to
register the immobilizer-ECU and input the vehicle secret code
and to register the password (secret code) that the owner spec-
ifies 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 10 seconds, the theft-alarm indi-
cator will blink for approximately 30 seconds.
NOTE: powertrain control module 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 diagnostic trou-
ble codes, and after carrying out any necessary repairs, repeat
the operation.
If an incorrect password is input five times in a row, the immobi-
lizer-ECU judges that an unauthorized operation is being
attempted. Start-prevention mode will be set, and engine oper-
ation will stop and all special functions will be disabled. If the
ignition switch is turned to "ON" position and left in that position
for approximately 20 minutes, "Unauthorized operation, start-
prevention mode" will be cancelled.

KEY ID REGISTER

All ignition keys can be registered with scan tool MB991958.
Additional ignition keys can be registered with or without scan
tool MB991958.
If an ignition key is registered using scan tool MB991958, no
registered ignition keys must be lost.

.

Registration with scan tool

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to "LOCK" (OFF) position before connect-
ing or disconnecting scan tool MB991958.

• Before registration, check that no DTC code is set. If a DTC

code is set, resolve the problem beforehand.

• 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 scan

tool MB991958 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.54-42

.

1. Connect scan tool MB991958 to the 16-pin data link
