The PIM performs the following functions:
• The PIM acts as the communication gateway between the GM LAN communications proto col and keyword 2000
protocol.
• The PIM converts analogue si gnals from the cruise control switches into digital serial data.
• The PIM upon inputs received from the engi ne control module (ECM), transmission control module (TCM) and
immobiliser control unit (ICU) controls the operation of the following instruments and warning lamps. Refer to
Section 6E1-1 Powertrain Interface Module – V6 for further information on the powertrain interface module.

4 Diagnostics
4.1 Diagnostic General Descriptions
The immobiliser control un it (ICU) diagnostic procedure is organised in a logical structure that begins with the Diagnostic
System Check. The Diagnostic System Check directs the diagnostic proce dure to the logical steps or appropriate
diagnostic table required to diagnose an immobiliser fau lt cond ition.
The diagnostic tables locate a faulty circuit or component through a logical based process of elimination. Correct use of
the diagnostic tables is essential to reduce di agnostic time and to prevent misdiagnosis.
In addition, the Diagnostic System Check provides the following information:
• identification of the ICU,
• condition of the diagnostic circuit, and
• identification and status of the DTCs if present.
Diagnostic Trouble Code (DTC) Tables
The diagnostic procedure is directed to a diagnostic trouble code (DTC) table if there are DTCs currently stored in the
ICU.
The diagnostic tables are designed to locate a faulty circuit or component through a logic al based process of elimination.
The diagnostic tables are developed with the following assumptions:
• the vehicle functioned correctly at the time of assembly,
• there are no multiple faults, and
• the problem currently exists.
Multiple DTCs
When performing a DTC check and there are multiple DT Cs, the diag nostic process must begin with the most likely DT C
that may trigger other DTCs.
Knowledge of the ICU and Tech 2 limitations are important to reduce diagn ostic time and to prevent misdiagnosis. Refer
to 6.1 Diagnostic Requirements, Precautions and Preliminary Checks.
Diagnostic Trouble Codes (DTCs)
When the ignition s witch is turned on, the ICU performs an internal integrity check that detects and isolates any interna l
faults. The PIM also monitors the serial data bus for messages from the po wertrain interface module. If a fault is detected
by the PIM, it will log a Diagnostic Trouble Code (DTC) that represents the fault detected. The DTCs stored in the PIM
may be accessed using Tech 2.
Status of DTCs
The ICU designates the DTCs logged into a Current or History DTC.
Current DTCs
If the fault condition that triggers the DTC is present during the last ICU self test, that DT C will be designated as a current
DTC.
History
DTCs
If the fault condition that triggers the DTC is not present during the last ICU self test, that DTC will be designated as a
history DTC.
Conditions for Clearing DTCs
• If there is no DTC logged in the current ICU self test, the current DTC will be cleared.
• If there is no DTC logged after 100 consecutive drive cycles, the history DTC will be cleared.
Immobiliser System – HFV6 Page 6E1–10
Page 6E1–10
Tech 2 ICU Diagnostic Tests
Tech 2 Limitations
Some DTCs trigger other DTCs to set, which causes Tech 2 to display multiple DTCs. In those situations, Tech 2 may
display more DT Cs than is neede d to rectify a fault.
When Tech 2 displays an o utp ut function, it displays only the command given by the ICU. If a connector is disconnected,
that fault will not register in the ICU output function. Tech 2 does not verify the command action.
The service technician must understand t he system being diagnosed as well as the correct use and limitations of Tech 2
to be able to perform diagnostic procedures efficiently and successfully.
Tech 2 Intermittent Fault Tests
The following are lists of Tech 2 diagnostic tests that may be used to diagnose intermittent faults:
• Wiggle test the suspected ICU wiring harne ss and connector while observing Tech 2 operating paramet ers of the
circuit being tested. If Tech 2 read-out fluctuates during this procedure, check the wiring harness circuit for loose
connection.
• Road test the vehicle in conditions that trigger the intermittent fault while an assistant observes the suspected Tech
2 operating parameter data.
• Capture and store data in the Snapshot mode when the fault occurs. The stored data may be repl ayed at a slower
rate to aid in diagnostics. Refer to Tech 2 User Instructions for more infor mation o n the Snapshot function.
• Operate suspected components to test their operation using Tech 2 Output Control Data.

6 Diagnostics Starting Point
6.1 Diagnostic Requirements, Precautions
and Preliminary Checks
Basic Knowledge Required
A lack of basic understanding of electronics,
electrical wiring circuits and use of electrical
circuit testing tools when performing the ICU
diagnostic procedures could result in
incorrect diagnostic results or damage to
components.
In addition, understanding of the Engine Management System is essential to prevent misdiagnosis an d component
damage. Refer to Section 6C1-1 Engine Ma nagement – V6 – General Information.
Basic Diagnostic Tools Required
Use of incorrect electrical circuit diagnostic
tools when performing the ICU diagnostic
procedures could result in incorrect
diagnostic results or damage to components.
The following electrical circuit testing tools are required to perform the diagnostic procedu r es detailed in this Section:

Diagnostic Precautions
• Use only the test equipment specified in the diagnostic tables. Other test equipment may either give incorrect
results or damage serviceable components.
• Do not clear any DTCs unless instructed.
• The fault must be present when using the DTC Diagnostic T ables. Otherwise, misdiagnosis or replacement of
serviceable parts may occur.
• Always use connector adapters such as those contained in connector test adapter kit Tool No. J35616-A to prevent
connector terminal damage.
• Thorough inspection of the wiring circuits and connectors listed in the diagnostic procedures must be performed,
otherwise misdiagnosis may occur.
• Inspect the electrical circuitry or connector terminals that are suspected to be causing the compl aint for the
following conditions:
• backed-out connector terminals,
• improper wiring connector mating,
• broken wiring connector locks,
• damaged connector terminals, and
• physical damage to the wiring harness.
• Before replacing a component, inspect its connector terminal for corrosion or deformation that may cause the fault
condition.

7 Intermittent Fault Conditions
7.1 Intermittent Conditions Diagnostic Table
Description
A fault condition is intermittent if one of the following conditions exists:
• The fault condition is not al ways present.
• The fault condition cannot be presently duplicated.
• There is no current DTC but a History DTC is stored.
Diagnostic Table
Checks Actions
Preliminary • Perform the Preliminary Chec ks, refe r to 6.1 Diagnostic Re quirements,
Precautions and Preliminary Checks.
• Gather information from the customer regarding the conditions that trigger the
intermittent fault such as:
• At what engine or ambient temperature range do es the fault occur?
• Does the fault occur when operating aftermarket electrical equi pment inside
the vehicle?
• Does the fault occur on rough roads or in wet road conditions?
Harness / Connector Install Tech 2 and perform the Tech 2 Intermittent Fault Tests. Refer to
4.1 Diagnostic General Descriptions for information on Tech 2 ECU diagnostic tests.
Warning Indicator The following conditions may cause an intermittent service vehicle soon (SVS) Lamp
fault with no DTC listed:
• Electro Magnetic Interference (EMI) caused b y a faulty relay, ECM controlled
solenoid, switch or other external source.
• Incorrect installation of aftermarket electrical equipment such as the following:
• mobile phones,
• theft deterrent alarms,
• lights, or
• radio equipment.
• Loose ICU or PIM ground connections.

Checks Actions
Temperature Related The Tech 2 Freeze Frame / Failure Records or Snapshot data may be used if applica ble
to the fault condition. Refer to 4.1 Diagnostic General Descriptions for information on
Tech 2 ECU diagnostic tests.
• If the intermittent fault is heat related, review the Tech 2 data in relationshi p to the
following:
• high ambient temperature,
• underhood / engine generate d heat,
• circuit generated heat due to a poor electrical connection or high electrical
load, and
• higher than normal load conditions (towing, etc.).
• If the intermittent fault is related to cold ambient or engine temperature, review the
Tech 2 data in relationship to the following:
• low ambient temperature, and
• the fault condition that occurs only on a cold start situation.
Additional Tests • Check for incorrect installation of aftermarket electrical equipment such as the
following:
• mobile phones,
• theft deterrent alarms,
• lights, or
• radio equipment.
• Check for Electro Magnetic Interference (EMI) caused b y a faulty relay, ECM
controlled solenoid or switch. The fault is triggered when the relay or solenoid is
activated.
• Check the A/C compressor clutch and some rela ys that contain a clamping diode
or resistor for an open circuit.
• Check the generator for a faulty rectifier bridge that may allow A/C noise into the
ICU or PIM electrical circuit.
When all diagno sis an d repairs are completed, check the engine management system for correct operation.

9 Immobiliser Security and
Programmi ng
9.1 Security and Programming Information
Car Pass Card
When performing certain immobiliser programming functions using Tech 2, you may be prompted to enter a four digit
Security Code. This informati on is found on the vehicle security card issued with the vehicle when new. If the card is
unavailable, contact the GM Holden Technical Assistance (TAS) centre to obtain the relevant Security Code.
lmportant information on Programming
Security code
The security code protects the immobilizer co ntrol unit against unauthorized programming and data access from Tech-2.
The security code consists of a 4 digit code number and is programmed into the immobilizer control unit and engine
control module (ECM).
New control units are not programmed with a security code.
If the control units are replaced, the security code entered on the car pass card, transponder l D etc, must be
programmed into the new control unit with Tech-2.
The security code can only be programmed with Tech-2 once and must therefore be performed with great care.
Once programmed, the security code cannot be overwritten. An already used immobilizer can be reused in a different car
by initializing the immobilizer. After that you can program the security code again. F or initializing command you need the
current security code.
If the immobilizer control unit is returned, al ways enclose the security code that is allocated to that control unit. If this is
not done, we can not process the case and the warranty will not be recognized.
Entering a code
If the Tech-2 display requests that the
• security code,
• mechanical key number, and the
• Vehicle Identification No.
to be entered, process as follo ws;
To input a digit you need to use the up and down buttons of the Tech-2. By using the numeric buttons the accordin g digit
will be displayed at the current position and the cursor will move to the next position.
For letters you need to use the up and do wn buttons of the Tech-2. The up and down key might be used for digits as
well. By using the up and do wn buttons the displa yed digit or letter will be increased or decreased.
To move to the next position you need to use the move-to-right-button.
With the two buttons, move-to-right and move-to-left you can select the position of numb er you want to change.
This will allow you to correct a wrong number.
After the number is completed you need to press the Enter b utton to accept the number. Correction is now no longer
possible.
Use the OKAY soft key to program the number and the NOT OKAY soft key to abort the programming.
NOTE: If an incorrect code is entered, the ICU 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 se curity code be entered after the initial wait time has elapsed, the ICU 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. The ignition switch must be in the ON position with the battery
connected during the wait time period.
Immobiliser System – HFV6 Page 6E1–36
Page 6E1–36
The wait time stages are as follows:
• Stage 1 = 10 seconds.
• Stage 2 = 10 seconds.
• Stage 3 = 10 minutes.
• Stage 4 = 20 minutes.
• Stage 5 = 40 minutes.
• Stage 5 = 80 minutes.
Transponder (Key)
If a transponder key is lost:
If a transponder key is lost, all transponder keys in the immobilizer control system must be erased. Transponder keys
can be ordered via the "Your proper organizat ion name such as part and accessory department" as previously by
providing the mechanical key number.
The mechanical key number is provided on the car pass card.
Thereafter, existing and new transponder keys are programmed consecutiv ely using Tech-2. The vehicle can then no
longer be started using lost key.
5 transponder keys can be provided:
Each transponder has different Identifications. If a customer wants more than 2 transponder keys, maximum 5
transponder keys can be prov ided by additional programming b y Tech-2.
If installation of an ignition lock with a different mechanism key number is necessary (an ignition lock which belongs to
the mechanical key number has to be ordered first), all transponder keys must first be erased and the two transponder
keys which belong to the ignition lock that is now installed must be programmed.
The new mechanical key number must be programmed no w into the immobilizer. The mechanical ke y number in the car
pass is to be changed as well.
Important:
After successful programming, the engine control can only be used for vehicles with immobilizer and transponder.
Faults that occur in connection with the immobilizer control unit are recog nized by the engine control unit and as l on g as
"IMMOBILOZER" is not programmed, are indicated by a flashing of the check engin e lamp.
If the immobilizer and engine control u nit are replaced at the same time, the immobilizer control unit must be
programmed first before the "IMMOBILIZ ER" function in the engine control unit can be activated.
Immobiliser System – HFV6 Page 6E1–37

9.2 Immobiliser Control Unit Reset
Procedure
Do not perform the reset procedure within
sixty seconds of turning the ignition switch
on. Failure to comply may result in the PIM
failing to reset.
When an immobiliser control unit (ICU) has been installed into a vehicle, it is security linked to the powertrain interface
module (PIM) and engine control module (ECM). Once this linking has been performed, the ICU cannot be installe d in
any other vehicle, unless the security linking between the PIM and the ECM has been reset using th e following
procedure:
1 Prior to resetting the PIM, obtain the Security Code. For further information, refer to Car Pass Card.
2 Connect Tech 2 to the data link connector (DLC) and turn the ignition switch on.
3 On Tech 2 select: Body / Immobiliser / Additional Functions / Reset Immobiliser.
