Immobilizer System -3-
INTRODUCTION & IMMOBILIZER CONTROL COMPONENTS
The immobilizer controls engine starting along with the engine
control module (ECM). The main system components are the
ICU, the ECM and the transponder key. The immobilizer
system is activated (immobilized) by an incorrectly
programmed or non-programmed transponder key, the ICU or the ECM. While this system is activated, the ECM controls the
fuel injection system and starter cut relay in order to fail to
engine running. An overview of engine starting sequence is
listed below.
1. Transponder key
2. ICU
3. CAN communication bus
4. ECM
5. Anti-theft control unit (with anti-theft system)
1. When the ignition switch is ON, the ICU begins
authentication of the transponder key in the steering
lock. The ICU transmits a specific request signal to the
transponder key and the transponder key sends back a
response signal to the ICU. Both communication signals
are carried out via antenna coil.
2. Because the anti-theft system alarms if a key or other
methods unlock the door, when the transponder key is
correctly authenticated the ICU transmits an alarm
cancel (disarm) signal to the anti-theft control unit. (With
anti-theft system)
3. After the transponder key authentication is completed,
the ICU begins authentication of the ECM. The ECMtransmits 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.
4. After the ECM authentication is completed, the ECM
enables engine running.

TRANSPONDER KEY
The transponder key accommodates a transponder chip in the
grip portion. The transponder keys have no conventional
power supply. The transponder chip is energized via a high
frequency alternating voltage supplied from an antenna coil
fitted around the steering lock cylinder. Only transponder keythat is correctly programmed key is possible to engine run.
Maximum five transponder keys can be provided by additional
programming.

IMMOBILIZER CONTROL UNIT (ICU)
The ICU is installed to the steering lock. The ICU controls the
immobilizer system by authentication of the transponder key
and the ECM. An antenna coil is a part of the ICU and it is
located around steering key lock cylinder. An antenna coil is
energized when the ICU is performing an authentication of thetransponder key.

ICU Communication
Communication with Scan Tool
The engine control module (ECM), transmission control module
(TCM) (AISIN A/T only) and ICU all communicate with the scan
tool over the controller area network (CAN) link.
Communication with Other Modules
The ECM, TCM, ICU and the data recording module (DRM)
communicate with each other over the same CAN link.
Following signals are communicated via a CAN bus between
the ECM and ICU;
• Immobilizer request signal (from ECM to ICU)
• Immobilizer response signal (from ICU to ECM)

ENGINE CONTROL MODULE (ECM)
The ECM is located inside of engine compartment via mounting
bracket and is behind air cleaner case. The ECM mainly
controls the engine control and also exchanges a request
signal and a response signal to an ICU. If fault occurs on
immobilizer system, the ECM sets DTC(s) and illuminates theservice vehicle soon (SVS) lamp (Euro 4 specification) or the
malfunction indicator lamp (MIL) (Except Euro 4 specification).

IMMOBILIZER CONTROL SYSTEM FLOW
STEP 1 (Transponder Key Authentication)
When the ignition switch is ON, the ICU supplies a high
frequency alternating voltage to the antenna coil. The antenna
transmits this alternating voltage to the transponder key (1a) to
energize the transponder chip. After that, the transponder chipsends back the transponder ID code to the ICU via the antenna
coil (1b).
After reading of the transponder ID code, the ICU starts cipher
communication with the transponder key. The ICU calculates a
random number of request signal (1c) that is called “Challenge”
signal. This random number is transmitted to the transponder
key via the antenna coil (1d). Then, the ICU receives the
“Response” signal (1e) matches with the value that the ICU
calculates using the secret key and transmitted random
number “Challenge” signal, the ICU recognizes a cipher
communication is OK (1f).

The transponder ID is key specific code and it must be
programmed into the ICU. During programming of the new
transponder key(s), a secret key is programmed into the
transponder chip and it cannot be reprogrammed again. When
replacing both ICU and ECM at the same time, a new secret
key 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).
The listed DTCs are associated to the transponder key or
transponder key communication problem.
B0003 Transponder Key Problem:The ICU never receive a response signal from the transponder
key, which is most likely caused by an objects that block
transponder key in the steering lock or ignition switch has been
turned ON without transponder key.
B0008 Wrong Transponder Key:
The ICU receives a wrong response signal from the
transponder key, which is most likely caused by a transponder
key is transferred (swapped) from another vehicle.
B0009 No Transponder Key Programmed:The ICU detects any transponder key is not programmed.
B0010 Unknown Transponder Key:
The ICU receives an unknown response signal from the
transponder key.
B0012 Default Transponder Key:
The ICU detects a default transponder key (non-programmed
new key).
B0013 Previously Erased Transponder:
The ICU detects a response signal that was previously erased
transponder key by some reason.

STEP 2 (Anti-theft System Disarm)
As soon as transponder key authentication has been
completed, the ICU transmits a signal to the anti-theft control
unit (ACU). Because the anti-theft system alarms if a key or
other method unlock the door, when the transponder key is
correctly authenticated the ICU transmits an alarm cancel
(disarm) signal to the ACU (2).

“Response” signal (3c) match with the value that the ECM
calculating using secret key and transmitted random number
“Challenge” signal, the ECM recognizes a cipher
communication is OK (3d). Both communication signals (3b &
3c) are carried out via the controller area network (CAN)
communication bus.
The listed DTCs are associated to the ECM communication
problem.
B0007 No Engine Request Received:The ICU never receive a request signal from the ECM within 2
seconds, which is most likely caused by a ECM communication
has been cut or ECM damage.
B0014 Secret Key Error:
The ICU receives a wrong response signal from the ECM,
which is most likely caused by an ECM is transferred

DIAGNOSTIC SYSTEM CHECK – IMMOBILIZER
CONTROLS
Description
The Diagnostic System Check – Immobilizer Controls is an organized
approach to identifying a condition that is created by a malfunction in the
electronic immobilizer control system. The Diagnostic System Check
must be the starting point for any immobilizer system concern. The
Diagnostic System Check directs the service technician to the next logical
step in order to diagnose the concern. Understanding and correctly using
the diagnostic table reduces diagnostic time, and prevents the
replacement of good parts.
DIAGNOSTIC STARTING POINT – IMMOBILIZER
CONTROLS
Begin the system diagnosis with Diagnostic System Check Immobilizer
Controls. The Diagnostic System Check – Immobilizer Controls will
provide the following information:
Test Description
The numbers below refer to the step numbers on the diagnostic table.
2. Lack of communication may be because of a partial or a total
malfunction of the controller area network (CAN) serial data circuit. The
specified procedure determines the particular condition.
6. The presence of DTCs which begin with U, indicate that some other
module is not communicating.
9. If there are other modules with DTCs set, refer to the DTC list. The
DTC list directs you to the appropriate diagnostic procedure.
• The identification of the control modules which command the system.
• The ability of the control modules to communicate through the serial
data circuit.
• The identification of any stored diagnostic trouble codes (DTCs) and
the their statuses.
The use of the Diagnostic System Check – Immobilizer Controls will
identify the correct procedure for diagnosing the system and where the
procedure is located.
Important!
• DO NOT perform this diagnostic if there is not an immobilizer
system concern, unless another procedure directs you to this
diagnostic.
• Before you proceed with diagnosis, search for applicable servicebulletins.
• Unless a diagnostic procedure instructs you, DO NOT clear the
DTCs.
• Ensure the battery has a full charge.
• Ensure the battery cables (+) (-) are clean and tight.
• Ensure the ICU grounds are clean, tight, and in the correct location.
• Ensure the ICU harness connector is clean and correctly connected.
• Ensure the ICU terminals are clean and correctly mating.
• Ensure the immobilizer security information correctly programmedinto the ICU and ECM.
• Ensure the ICU is correctly installed to the steering lock.
• Ensure objects does not block transponder key in the steering lock.
• Ensure another transponder key is not attached to the key ring.

RESETTING & PROGRAMMING GUIDELINES
• Vehicle security information card to a new owner.
• Blank vehicle security information card it is for reissue.• Instruct to your dealership how to use it.
Vehicle Security Information Card (If issued)
When performing ICU, ECM or transponder key(s) resetting or
programming functions using a scan tool, you will be prompted
to enter four digits of security code (1). This information is
found on the vehicle security information card issued with the
vehicle when new. If the card is unavailable, contact a
distributor’s service department to obtain the relevant securitycode. For new owners, distributor or dealership must provide
vehicle security information card that has identification
numbers of owner’s vehicle immobilizer system. This
information is very important in case of repair or transponder
key is lost. It is necessary to provide following items in your
responsibility.
RESETTING & PROGRAMMING
Notice!
The security information must be programmed when the ICU,
ECM or transponder key(s) is replaced, or transponder key(s)
is added.

• The data requested under items 1 to 10 must be provided
completely, including the authorized dealership number, the
vehicle identification number (VIN) and engine type/ number.
• Complete the form by entering data and signature/
authorized dealership stamp and send it along with proof of
ownership to address provided in the form.• The requested data will be sent by fax to dealership that
made the request after your organization has confirmed that
the information is correct.
Your organization must keep security code for all vehicles as
confidential data. In case of vehicle security information card is
lost, the data can be requested from a distributor’s service
department. This request will only be processed if
accompanied by the enclosed form and proof of ownership.
Once the data is received, it can be entered in a blank card and
given to the customer. The unused card should be destroyed.
Instructions on filling out the Data Request Vehicle Security
Information Card as follows.

Security Code
The security code is required when performing ICU, ECM or
transponder key(s) resetting or programming functions. When
a scan tool requests the security code to be entered, and an
incorrect code is entered, the ICU or ECM will go into a security
wait time stage. This wait time stage will prevent any further
attempts to enter the security code until the wait t ime has
elapsed. Should a second incorrect security code be entered
after the initial wait time has elapsed, the ICU or ECM will go
into a second wait time stage. The wait time will increase each
time an incorrect code is entered. When the correct code is
entered the wait time will reset back to its original value of 10
seconds.
• Stage 1 = 10 seconds
• Stage 2 = 10 seconds
• Stage 3 = 10 minutes
• Stage 4 = 20 minutes
• Stage 5 = 40 minutes
• Stage 6 = 80 minutes (1 hour 20 minutes)
• Stage 7 = 160 minutes (2 hours 40 minutes)
• Stage 8 = 320 minutes (5 hours 20 minutes)
• Stage 9 = 640 minutes (10 hours 40 minutes)
• Stage 10 = 1280 minutes (21 hours 20 minutes)
Notice!
The ignition switch must be kept at ON position during the
wait time period.

Transponder Key
Normally two or three transponder keys are provided with a
vehicle when new. Maximum five transponder keys can be
provided by additional programming if owner requests
additional key(s).
Notice!
During programming of the new transponder key(s), an
authentication code is programmed into the transponder chip
and it cannot be reprogrammed again. Once this
programming has been performed, the transponder keys
cannot be installed in any other vehicle.
Notice!
Keep away another key, another transponder key, keynumber plate or other metal items from the transponder key
that is going to program. Otherwise, transponder key(s)
programming may be failed.
