Caution: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise

9W-2 IMMOBILIZER SYSTEM
Notice
lIf vehicle is equipped with immobilizer system and the engine
cranks normally but not start, check immobilizer system first
rather than ignition and other electrical systems because it
can be disabled fuel supply of injectors by ECU due to
defective immobilizer system.
lProgramming of the immobilizer system will be performed
by authorized personnel only. If following defective codes
for immobilizer system appear during diagnosis of vehicle
with SCANNER, ask immobilizer programming to authorized
personnel and actual programming should be performed
by authorized personnel only.
Display of defectives relevant to immobilizer system :
SCANNER
1. No communication with transponder
2. No immobilizer programming
lThe transponder in the key can be damaged by shocks of
dropping or hitting other objectives, so handle it with care.
lEach supplied key has programming of code on its own.
Accordingly if ECU needs to be replaced, replace the
transponder in the key.
lThe vehicle equipped with immobilizer system will never be
started with remote ignition device, so do not attempt to
install it.
lThe immobilizer system will never be removed from the
vehicle. So never attempt to remove it to install a remote
ignition device or others.
lIf engine does not start during service, use every key to
start the engine and then check immobilizer system finally.
FUNCTION DESCRIPTION
Immobilizer is a device disabling vehicle ignition unless a speific key is used and designed to help prevent vehicle
theft.
Immobilizer is comprised of two devices, a key with encoded transponder and engine control unit(ECU) with the same
encoding of the transponder. When a key is inserted into the key hole to start vehicle and turned to ‘ON’, the ECU
reads and decodes the transponder code and, if the same, starts the engine, it is called immobilizer. It means
immobilizer system disables starting by stopping fuel supply if the code in the transponder does not match the code
stored in ECU each other.
Cases that requires immobilizer
programming
1. Replacement ECU
In this case, replace the every transponder
of the key at once.
2. Replacement of the transponder
3. Additional key for lost 1 or 2 keys
1 ) Clear all codes for current keys from the
ECU
2 ) When using current key : clear code of
the transponder and re-program it
3) Additional (purchased) key : perform
programming
4. When lost all keys
1 ) Clear all memorized key codes from the
ECU
2 ) Replace the key and key set
3 ) Immobilizer programming

IMMOBILIZER SYSTEM 9W-3
SYSTEM DESCRIPTION
Gasoline Version
The Immobilizer System consists of an electronic device with integrated coil, called ‘Active Antenna’, the crypto
transponder, which is integrated in the ignition key, and the engine management system (EMS).
The Active Antenna is mounted at the ignition lock and handles the following tasks :
lTo supply the transponder with power
lTo receive the data from the EMS and transmit it to the transponder
lTo receive and demodulate the data from the transponder and transmit it to the EMS
The whole Immobilizer software, the authentication and the management of valid keys is completely managed by the
EMS.
