11A-8 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
Diagnostic Information and Procedures
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:
• 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.
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. 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 serial data circuit.
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.
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 service bulletins.
• 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 ground is 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 is correctly programmed into the ICU, ECM and PIM.
• 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 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
