Resetting and Programming
Resetting and Programming Guidelines
Notice:The security information must be programmed
when the ICU, ECM, PIM or transponder key(s) is
replaced, or transponder key(s) is added.
Vehicle Security Information Card (If issued)
When performing ICU, ECM, PIM 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 security code.
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.
• Vehicle security information card to a new owner.
• Blank vehicle security information card it is for reissue.
• Instruction to your dealership how to use it.
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.
• 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.
Security Code
The security code is required when performing ICU,
ECM, PIM 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, ECM or PIM 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
time has elapsed. Should a second incorrect security
code be entered after the initial wait time has elapsed,
the ICU, ECM or PIM 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 rest 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

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 CONTROL SYSTEM (4JK1/4JJ1/HFV6) 11A-45
Description and Operation
Immobilizer System Description
Legend1. Transponder key
2. ICU
3. Controller area network (CAN) communication bus lines 4. Anti-theft control unit (with anti-theft system)
5. Engine control module (ECM) (4JK1/ 4JJ1)
6. Powertrain interface module (PIM)
7. Engine control module (ECM) (HFV6)

The immobilizer controls engine starting along with the
engine control module (ECM). The main system
components are the ICU, the ECM, the PIM (HFV6)
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. A typical engine starting
sequence is below.
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 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. 4. After the ECM authentication is completed, the
ECM enables engine running.
