an intermittent malfunction is suspected. Refer to HOW TO COPE
WITH INTERMITTENT MALFUNCTIONS
).

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.
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 approx. 10 seconds, the
immobilizer indicator will blink for approx. 30 seconds.

If none of the functions can be used, check the diagnostic trouble codes, and after
carrying out any necessary repairs, repeat the operation. If an incorrect password is
input five 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 and left in that position for approximately 16 minutes,
"Unauthorized operation, start- prevention mode" will be cancelled. KEY ID REGISTRATION All ignition keys can be registered with scan tool MB991958. Additional ignition
keys can be registered with or without scan tool MB991958. REGISTRATION WITH THE SCAN TOOL 1. Connect scan tool MB991958 to the data link connec
tor.
CAUTION: To prevent damage to scan tool MB991958, always
turn the ignition switch to "LOCK" (OFF) position
before connecting or disconnecting scan tool
MB991958.
NOTE:
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 ke
ys need to be re
gistered. 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
.
