IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6) 11A-35
DTC U0100
Circuit Description
When the transponder key authentication is completed,
the ICU begins authentication of the ECM. The ECM
transmits a specific request signal to the ICU and the
ICU sends back a response signal to the ECM. Both
communication signals are carried out via a controller
area network (CAN) communication bus. The ICU
monitors CAN operational status by expecting a
constant flow of messages from the ECM. If the ICU
fails to send an expected message to the ECM, this
DTC will set.
Condition for Setting the DTC • The ICU detects that the CAN Bus OFF status. Action Taken When the DTC Sets
• The engine will fail to run if the fault occurs before starting the engine.
Condition for Clearing the DTC • A current DTC clears once ignition cycle has occurred without the fault recurring.
• A history DTC will clear after 50 consecutive ignition cycles, if the condition for malfunction is no
longer present.
• Use a scan tool to clear the DTC.
Diagnostic Aids • Electromagnetic interference may affect intermittent condition.
• Any communication fault with the ECM may set this DTC.

PIM Programming Procedure must be done
whenever any of the following condtions are met:
• Diagnostic chart instructs you to program PIM
• New PIM is installed
• PIM is reused that was rest in an original vehicle
ICU & PIM Programming Procedure must be done
whenever any of the following condition is met:
• New or resued ICU and PIM are installed at the same time
ECM & PIM Programming Procedure must be done
whenever any of the following condition is met:
• New or reused ECM and PIM are installed at the same time
ICU & ECM Programming Procedure must be done
whenever any of the following condition is met:
• New or reused ICU and ECM are installed at the same time (transponder key(s) also replaced)
ICU, ECM & PIM Programming Procdure must be
done whenever any of the following condition is met:
• New or reused ICU, ECM and PIM are installed at the same time (transponder key(s) also replaced)
Notice: During programming of the new transponder
key(s), an authentication code is programmed into the
transponder chip and it cannot be reprogrammed
again. When replacing both ICU and ECM at the same
time, a new authentication code to be programmed into
the newly installed ECM is based on information of
newly installed ICU. However, the transponder keys
cannot be reprogrammed therefore it must be replaced.
Do not replace the ICU and the ECM at the same time
to avoid needless transponder key(s) replacement
simultaneously unless complete damaging was
encountered (e.g. both modules cannot be
communicated with a scan tool).

IMMOBILIZER SYSTEM (C24SE, 4JA1-T) 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.
• W arning buzzer is operating.

IMMOBILIZER SYSTEM (C24SE, 4JA1-T) 11A-5
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.
W hen 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?
W hen 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.
