ON-VEHICLE SERVICE

HOW TO REGISTER ENCRYPTED CODE

M1543008100670

Required Special Tools:

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

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

• MB991827: MUT-III USB Cable

• MB991910: MUT-III Main Harness A (Vehicles with CAN

communication system)

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 regis-
tered accessible.
If the ignition key, ETACS-ECU, Engine-ECU is replaced,
encrypted codes of all the ignition keys must be registered. (A
maximum of eight different ignition keys can be registered).
Moreover, when the ETACS-ECU has been replaced, you will
need to use diagnostic tool MB991958 to register the
ETACS-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 Engine warning lamp
indicator will blink for approx. 30 seconds.

NOTE: Engine-ECU has an encrypted code for ETACS-ECU,
and the encrypted code is registered in the ETACS-ECU and
ignition key.
