Immobilizer System

DESCRIPTION
The immobilizer system will disable the vehicle unless the proper ignition key is used, in addition to the currently
available anti- theft systems such as car alarms, the immobilizer system aims to drastically reduce the rate of auto
theft.
1. SMARTRA type immobilizer
a. The SMARTRA system consists of a transponder located in the ignition key, an antenna coil, a SMARTRA unit,
an indicator light and the PCM(ECM).
b. The SMARTRA communicates to the PCM(ECM) (Engine Control Module) via a dedicated communications line.
Since the vehicle engine management system is able to control engine mobilization, it is the most suitable unit
to control the SMARTRA.
c. When the key is inserted in the ignition and turned to the ON position, the antenna coil sends power to the
transponder in the ignition key. The transponder then sends a coded signal back through the SMARTRA unit to
the PCM(ECM).
d. If the proper key has been used, the PCM(ECM) will energize the fuel supply system. The immobilizer indicator
light in the cluster will simultaneously come on for more than five seconds, indicating that the SMARTRA unit
has recognized the code sent by the transponder.
e. If the wrong key has been used and the code was not received or recognized by the PCM(ECM) the indicator
light will continue blinking for about five seconds until the ignition switch is turned OFF.
f. If it is necessary to rewrite the PCM(ECM) to learn a new key, the dealer needs the customer's vehicle, all its
keys and the Scan tool (pro) equipped with an immobilizer program card. Any key that is not learned during
rewriting will no longer start the engine.
g. The immobilizer system can store up to four key codes.
h. If the customer has lost his key, and cannot start the engine, contact motor service station.
COMPONENTS OPERATIONS
PCM (Power Train Control Module)
1. The PCM(ECM) carries out a check of the ignition key using a special encryption algorithm, which is programmed
into the transponder as well as the PCM(ECM) simultaneously. Only if the results are equal, the engine can be
started. The data of all transponders, which are valid for the vehicle, are stored in the PCM(ECM).

TEACHING PROCEDURES
1.Key Teaching Procedure
Key teaching must be done after replacing an inoperative PCM(ECM) or when providing additional keys to the
vehicle owner.
The procedure starts with an PCM(ECM) request for vehicle specific data (PIN code: 6digits) from the tester. The
"virgin" PCM(ECM) stores the vehicle specific data and the key teaching can be started. The "learnt" PCM(ECM)
compares the vehicle specific data from the tester with the stored data. If the data are correct, the teaching can
proceed.
If incorrect vehicle specific data have been sent to the PCM(ECM) three times, the PCM(ECM) will reject the
request of key teaching for one hour. This time cannot be reduced by disconnecting the battery or any other
manipulation. After reconnecting the battery, the timer starts again for one hour.
The key teaching is done by ignition on with the key and additional tester commands. The PCM(ECM) stores the
relevant data in the EEPROM and in the transponder. Then the PCM(ECM) runs the authentication required for
confirmation of the teaching process. The successful programming is then confirmed by a message to the tester.
If the key is already known to the PCM(ECM) from a previous teaching, the authentication will be accepted and the
EEPROM data are updated. There is no changed transponder content (this is impossible for a learnt transponder).
The attempt to repeatedly teach a key, which has been taught already during the same teaching cycle, is
recognized by the PCM(ECM). This rejects the key and a message is sent to the tester.
The PCM(ECM) rejects invalid keys, which are presented for teaching. A message is sent to the tester. The key
can be invalid due to faults in the transponder or other reasons, which result from unsuccessful programming of
data. If the PCM(ECM) detects different authenticators of a transponder and an PCM(ECM), the key is considered
to be invalid.
The maximum number of taught keys is 4
If an error occurs during the Immobilizer Service Menu, the PCM(ECM) status remains unchanged and a specific
fault code is stored.
If the PCM(ECM) status and the key status do not match for teaching of keys, the tester procedure will be stopped
and a specific fault code will be stored at PCM(ECM).
