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.

Scan Tool Data List
The Immobilizer Scan Tool Data List contains all
immobilizer related parameters that are available on
the scan tool. Use the Immobilizer Scan Tool Data List
only after the following is determined:
• The Immobilizer Controls - Diagnostic System Check is completed. • On-board diagnostics are functioning properly.
A scan tool that displays faulty data should not be used.
Use of a faulty scan tool can result in misdiagnosis and
unnecessary parts replacement.
Only the parameters listed below are referenced in this
service manual for use in diagnosis.
Scan Tool Data Definitions
This information will assist in immobilizer problems.
Always perform the Diagnostic System Check -
Immobilizer Controls first. The Diagnostic System
Check will confirm proper system operation.
Ignition Status
This parameter displays the state of the ignition switch
input to the ICU. On indicates the ignition switch is
turned ON position.
Transponder Key
This parameter displays the state of the transponder
key in the steering lock. Transponder Key 1 to 5
indicates a correctly programmed transponder key is
used. The number 1 to 5 indicates which transponder
key is used. Invalid indicates an incorrect key is in
used. Not Programmed Key indicates a non-
programmed new transponder key is used. No
Transponder Key indicates ICU does not recognize a
transponder key. Transponder Status
This parameter displays the state of the transponder
key in the steering lock. Correct Transponder-Key
indicates a correctly programmed transponder key is
used. Wrong Transponder-Key indicates an incorrect
key is in used. New Transponder-Key indicates a non-
programmed new transponder key is used. No
Transponder Detected indicates ICU does not
recognize a transponder key.
Transponder-Key 1 to 5 Status
This parameter displays the state of number of
programmed transponder key(s). Programmed
indicates transponder key 1 to 5 is correctly
programmed. The number 1 to 5 indicates programmed
order.
Security Code Programmed
This parameter displays the state of the security code
programming. Yes indicates a security code is correctly
programmed. No indicates a security code is not
programmed.

11A-24 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
DTC B0003
Description
When the ignition switch is ON, the ICU begins
authentication of the transponder key in the steering
lock through the antenna coil. Once the ICU transmits a
signal, the transponder must send back a specific
response signal. If the ICU never receives a response
signal from the transponder, this DTC will set.
Condition for Running the DTC • The ignition switch is ON.
Condition for Setting the DTC • The ICU does not receive a response signal from the transponder key.
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.
• An antenna coil problem may set this DTC.
• Objects that block transponder key in the steering lock may set this DTC.
• Another key that is attached to the key ring may affect this DTC to set.
• If the ignition switch has been turned ON without transponder key this DTC sets.
