IMMOBILIZER SYSTEM
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 noted.

9T2-2 IMMOBILIZER SYSTEM
DESCRIPTION AND OPERATION
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.
Notice:
If 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.
Programming 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 per-sonnel only.
Display of defectives relevant to immobilizer
system : SCANNER
1. No communication with transponder
2. No immobilizer programming
The transponder in the key can be damaged by
shocks of dropping or hitting other objectives, so
handle it with care.
Each supplied key has programming of code on
its own. Accordingly if ECU needs to be replaced,
replace the transponder in the key.
The vehicle equipped with immobilizer system will
never be started with remote ignition device, so
do not attempt to install it.
The immobilizer system will never be removed from
the vehicle. So never attempt to remove it to install
a remote ignition device or others.
If engine does not start during service, use every
key to start the engine and then check immobilizer
sys-tem finally.
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 trans-
ponder 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

4. Remove the transponder. Carefully remove the old
shock absorbing sealant with a razor blade if
applied.
5. Replace the transponder with new one, and apply
the small amount of shock absorbing sealant.
