SHDBE6543L
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. Encrypted SMARTRA type immobilizer
- The SMARTRA system consists of a passivie
challenge - response (mutual
authentication)transponder located in the ignition
key, an antenna coil, a encoded SMARTRA unit,
an indicator light and the PCM(ECM).
- 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.
- 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).
- 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.
- 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.
- 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 Hi-scan (pro)
equipped with an immobilizer program card. Any
key that is not learned during rewriting will no
longer start the engine.
- The immobilizer system can store up to eight key
codes.
- If the customer has lost his key, and cannot start
the engine, contact Hyundai motor service station.

Components Operations
PCM (Power Train Control Module)
1. The PCM(ECM) (A) 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).
ERN (Encrypted Randorn Number) value between
EMS and encrypted smartra unit is checked and the
validity of coded key is decided by EMS.
SEDBE7547L
ENCRYPTED SMARTRA unit (A)
The SMARTRA carries out communication with the
built-in transponder in the ignition key. This wireless
communication runs on RF (Radio frequency of 125
kHz). The SMARTRA is mounted behind of the crash pad
close to center cross bar.
The RF signal from the transponder, received by the
antenna coil, is converted into messages for serial
communication by the SMARTRA device. And, the
received messages from the PCM(ECM) are converted
into an RF signal, which is transmitted to the transponder
by the antenna.
TheSMARTRAdoesnotcarryoutthevaliditycheckof
the transponder or the calculation of encryption
algorithm. This device is only an advanced interface,
which converts the RF data flow of the transponder into
serial communication to the PCM(ECM) and vice versa.
SFDBE8221L
TRANSPONDER (Built-in keys)
The transponder has an advanced encryption algorithm.
During the key teaching procedure, the transponder will
be programmed with vehicle specific data. The vehicle
specific data are written into the transponder memory.
The write procedure is once only; therefore, the contents
of the transponder can never be modified or changed.
SHDBE6540D
Antenna coil
The antenna coil (A) has the following functions.
- The antenna coil supplies energy to the transponder.
- The antenna coil receives signal from the
transponder.
- The antenna coil sends transponder signal to the
SMARTRA.
It is located directly in front of the steering handle
lock.

Teaching Procedures
1. Key Teaching Procedure
Key teaching must be done after replacing a
defective PCM(ECM) or when providing additional
keys to the vehicle owner.
TheprocedurestartswithanPCM(ECM)requestfor
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 8
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).
NOTICE
When teaching the 1st key, Smartra regists at the
same time.

2. User Password Teaching Procedure
The user password for limp home is taught at the
service station. The owner of the vehicle can select a
number with four digits.
The user password teaching is only accepted by a
"learnt" PCM(ECM). Before first teaching of user
passwordtoanPCM(ECM),thestatusofthe
passwordis"virgin"Nolimphomefunctionis
possible.
The teaching is started by ignition on, with a valid
key(learnt key) and sending the user password by
tester. After successful teaching, the status of the
user password changes from "virgin" to "learnt"
The learnt user password can also be changed. This
can be done if the user password status is "learnt"
and the tester sends authorization of access, either
the old user password or the vehicle specific data.
After correct authorization, the PCM(ECM) requests
the new user password. The status remains "learnt"
and the new user password will be valid for the next
limp home mode.
If wrong user passwords or wrong vehicle specific
data have been sent to the PCM(ECM) three times
continuously or intermittently, the PCM(ECM) will
reject the request to change the password for one
hour. This time cannot be reduced by disconnecting
the battery or any other actions. After reconnecting
the battery, the timer starts again for one hour.

Limp Home Function
1. LIMP HOME BY TESTER
If the PCM(ECM) detects the fault of the SMARTRA
or transponder, the PCM(ECM) will allow limp home
function of the immobilizer. Limp home is only
possible if the user password (4 digits) has been
given to the PCM(ECM) before. This password can
be selected by the vehicle owner and is programmed
at the service station.
The user password can be sent to the PCM(ECM) via
the special tester menu.
Only if the PCM(ECM) is in status "learnt" and the
user password status is "learnt" and the user
password is correct, the PCM(ECM) will be unlocked
for a period of time (30 sec.). The engine can only be
started during this time. After the time has elapsed,
engine start is not possible.
If the wrong user password is sent, the PCM(ECM)
will reject the request of limp home for one hour.
Disconnecting the battery or any other action cannot
reduce this time. After connecting the battery to the
PCM(ECM), the timer starts again for one hour.

2. LIMP HOME BY IGNITION KEY
The limp home can be activated also by the ignition
key. The user password can be input to the
PCM(ECM) by a special sequence of ignition on/off.
Only if the PCM(ECM) is in status "learnt" and the
user password status is "learnt" and the user
password is correct, the PCM(ECM) will be unlocked
for a period of time (30 sec.). The engine can be
started during this time. After the time has elapsed,
engine start is not possible. After a new password
has been input, the timer (30 sec.) will start again.
After ignition off, the PCM(ECM) is locked if the timer
has elapsed 8 seconds. For the next start, the input
of the user password is requested again.

Replacement Of Ecm And Smartra
In case of a defective ECM, the unit has to be replaced
with a "virgin" or "neutral" ECM. All keys have to be
taught to the new ECM. Keys, which are not taught to the
ECM, are invalid for the new ECM (Refer to key teaching
procedure). The vehicle specific data have to be left
unchanged due to the unique programming of
transponder.
In case of a defective SMARTRA, it needs teaching the
smartra. A new SMARTRA device replaces the old one
and smartra need teaching.

2. Things to remember before a replacement (Keys ＆
Additional registration)
SFDBE8406L
NOTICE
1. When there is only one key registered and you
wish to register another key, you need to
re-register the key which was already registered.
2. When the key #1 is registered and master key #2
is not registered, Put the key #1 in the IG/ON or
the start position and remove it. The engine can
be started with the unregistered key #2.
(Note that key #2 must be used within 10
seconds of removing key #1)
3. When the key #1 is registered and key #2 is not
registered, put the unregistered master key #2 in
the IG/ON or the start position.
The engine cannot be started even with the
registered key #1.
4. When you inspect the immobilizer system, refer
to the above paragraphs 1, 2 and 3.
Always remember the 10 seconds zone.
5. If the pin code password are entered
incorrectly on three consecutive inputs, the
system will be locked for one hour.
6. Be cautious not to overlap the transponder
areas.
7. Problems can occur at key registration or vehicle
starting if the transponders should overlap.
Neutralising Of ECM
The PCM(ECM) can be set to the "neutral" status by a
tester.
A valid ignition key is inserted and after ignition on is
recorded, the PCM(ECM) requests the vehicle specific
data from the tester. The communication messages are
described at "Neutral Mode" After successfully receiving
the data, the PCM(ECM) is neutralized.
The ECM remains locked. Neither the limp home mode
nor the "twice ignition on" function, is accepted by the
PCM(ECM).
The teaching of keys follows the procedure described for
the virgin PCM(ECM). The vehicle specific data have to
be unchanged due to the unique programming of the
transponder. If data should be changed, new keys with a
virgin transponder are requested.
This function is for neutralizing the PCM(ECM) and Key.
Ex) when lost key, Neutralize the PCM(ECM) then teach
keys.
(Refer to the Things to do when Key ＆PIN Code the
PCM(ECM) can be set to the "neutral" status by a
scanner.If wrong vehicle specific data have been sent to
SMATRA three times continuously or intermittently, the
SMATRA will reject the request to enter neutral mode for
one hour. Disconnecting the battery or other
manipulation cannot reduce this time. After connecting
the battery the timer starts again for one hour.
