IMMOBILIZER SYSTEM 11A-3

General Description
The immobilizer system consists of the four major
components which are Engine Control Module (ECM),
Immobilizer Control Unit (lCU), transponder, and scan
tool (Tech-2).
This system can be activated by a correctly programmed
transponder and starter switch is set to OFF.
This system can be deactivated by a correctl
y
programmed transponder key connected with a correctly
programmed ECM and a correctly programmed lCU.
While the system is on :
The starter cut off relay deactivates function of starter,
and the fuel injector power source is deactivated also.


Check Engine lamp is flashing.


Warning buzzer is operating.
(With antitheft system)






Gasoline Engine (6VE1, C24SE)

11A-6 IMMOBILIZER SYSTEM

What happens without proper transponder
operation?
One of the function of transponder is to deactivate or
activate starter function. lf the proper transponder is not
used, starter cannot be operated. Because starter rela
y
stays off, cranking engine is not possible.
After the starter relay is activated, transponder signal
triggers to let lCU calculate by transponder address
signal and immobilizer algorithm.
When the result matches with necessary condition, it
makes injector power source be activated.
If transponder does not send correct signal, lCU and
ECM do not activate injector system on.
Therefore the vehicle cannot be operated.
No proper transponder is available, what
should be done for the system?
When any proper transponder is not available, a new
transponder should be programmed. Up to 5
transponders can be provided with a scan tool (Tech-2)
and by proper procedure.
In addition to the absence of proper transponder, it ma
y
happen particular secret code to the particular vehicle is
missing. ln this case, the secret code must be provided
by your organization.
Otherwise transponder cannot be programmed in an
y
way.
lf the essential for a scan tool (Tech-2) for programming
and proper software for Tech-2 are not available, there
is no permanent way to fix system. Temporary replace
with new ECM, new ICU and new transponder without
any secret code can make the system be deactivated,
but it does not last long. Such a replacement does not
solve any condition. Even after replacement, the system
is activated automatically in short time and then no
operation of the vehicle can be made in any way.
Tech-2 should be provided in your organization.
Caution to the operation
lf an attempt is made to start the engine while the
immobilizer system is activated, the check engine lamp
flashes and the engine will not start.
Summary of operation
Switch on: Set the ignition and starter switch to OFF.
(Activate)
Switch off: Set the ignition and starter switch to ON b
y
using the transponder key. (Deactivate)

What your organization should provide for
your customer





Car Pass

For a new owner, your dealership must hand Car Pass
card, which has identification numbers of new owner's
vehicle immobilizer system. This information is ver
y
important in case of repair or lost of transponder.
The followings are necessary items provided by you
r
responsibility.
1)
Car pass with identification for a new owner
2)
Blank car pass card when it is for reissue
3)
Instruction to dealers how to use car pass card






Security code management

Your organization must keep security codes for all
vehicles as confidential data. Once the security codes
are lost, anybody who have the security code can
access immobilizer system. Your organization has
responsibility of any missing vehicles caused by stolen
security code.






Essential tool (Scan tool : Tech-2)

Your dealership must have Tech-2, and Tech-2 updated
software for immobilizer system.

IMMOBILIZER SYSTEM 11A-21

Tech-2 Features
1.
Tech-2 is a 12volt system. Do not apply 24 volts.
2.
After connecting and/or installing the vehicle
communication interface (VCI) module, PCMCI
A
card and data link connector (DLC) to the Tech-2,
connect the tool to the vehicle DLC.
3.
Make sure the Tech-2 is OFF when removing o
r
installing the PCMCIA card.
4.
The Tech-2 has the capability of two or three
snapshots.
5.
The PCMCIA card is sensitive to magnetism and
static electricity, so care should be taken in the
handling of the card.
6.
The Tech-2 can not plot a graph when replaying a
snapshot.
7.
Always return to the Main Menu by pressing the
EXIT key several times before shutting down.
8.
To clear diagnostic trouble codes (DTCs), open
Application Menu and press "Clear DTC ".

Before operating the Isuzu PCMCIA card with the Tech
2, the following steps must be performed:
1.
The Isuzu System PCMCIA card inserts into the
Tech 2.
2.
Connect the SAE 16/19 adapter to the DLC cable.
3.
Connect the DLC cable to the Tech 2.
4.
Mark sure the vehicle ignition is off.
5.
Connect the Tech 2 SAE 16/19 adapter to the
vehicle DLC.


RHD (For example)
