General Information
The Engine Immobiliser System is designed to provide ‘Drive-away’ protection by electronically disabling the fuel
system, ign iti on sy st em a nd th e s tarter mo tor rela y. It is a passiv e sy st em, r eq ui ring n o ac tion on the part of the d riv er
other than removing the ignition key from the switch.
When the ignition is turned ‘ON’, a complex process of data transfer takes place between the transponder type ignition
key, the Immobiliser Control Unit (ICU) and the Powertrain Control Module (PCM).
If any transmitted data is incorrect or missing, the ICU prevents starter motor relay operation and the PCM will prevent
the engine from runni ng.
When the engine has been shut down for more than twelve seconds, both the request and the immobiliser signal
change on the next ignition cycle, the complex data exchange taking place again.
If there is a malfunction - either an incorrect transponder signal or no communication between the components, engine
is disab led, the ‘C HECK ENG INE’ l amp in the instrume nt clus ter will bl ink rapi dly an d the rele vant Diagno st ic Trou ble
Code (DTC) is stored in both the ICU and the PCM.
System Components
The main system components are:
• Transponder Key
• Coil Antenna
• Immobiliser Control Unit (ICU)
• Coil Antenna
•Starter Relay
• Powertrain Control Module
• Associated wiring harnesses, connectors and fuses
Transponder Key
The system uses a conventional mechanical-cut ignition
key containing a minature transponder (transmitter/
responder) embedded in the plastic handle.
Each transponder is programmed with it’s own specific
ID code during manufacture. Up to 10
18
codes are
available with this system, making code duplication
almost impossible.
The transponder circuit in the key does not require
batteries - the opera tin g si gna l is prov id ed c or dle ss l y by
the ICU supplying a high frequency (133 kHz) AC
voltage signal to the coil antenna.
Encapsulated by the hard plastic of the key head, the
transponder is the most durable part of the ignition key.
The module is initially programmed with two
transponder codes, corresponding to the two keys
supplied with the vehicle. Should a key be lost, or an
additional key required, uncoded keys may be
programmed into the sy stem with the a id of TECH 2. A
maximum of 5 transponder codes can be stored in the
ICU.
Due to the complex nature of the coded signals
transmitted between the it is recommended to replace
existing ignition keys when the ICU is replaced.
Coil Antenna
A non-contact radio frequency is used to transfer
information between the transponder key and the
Immobiliser Control Unit. Surrounding the ignition lock is
a dipole antenna, which is connected to the ICU by a
wiring harness.
The antenna is designed to have a very limited range,
ensuring that only the key in the ignition lock can
communicate with the ICU. This excludes the possible
interference from other transponder keys in the vehicle.
The antenna is accessed by removing the steering
column shroud. Apart from a continuity test on the coil
windin g, substitu tion with a known g ood part is the only
applicable diagnostic procedure.
Immobiliser Control Unit (ICU)
The Immobiliser Control Unit (ICU) is located behind the
RH lower instrument panel. The ICU is powered at all
times from Fuse C-23 (Immo) and receives an ignition
‘ON’ signal from Fuse C-12 (Engine).
Communication from the ICU to the PCM is on the
Vehicl e Speed Sensor (VSS) signal wi re (ICU pin B8 to
PCM pin S27).
Communication from the PCM to the ICU takes place on
the ‘CHECK ENGINE ’ Lamp (CEL) contr ol circuit (PCM
pin S11 to ICU pin B7).
NOTE: If th e ICU and PCM are re placed at the same
time, the ICU MUST be programmed BEFORE the
Immobiliser function of the PCM can be activated.
Powertrain Control Module (PCM)
The PCM is located on the passenger side of the engine
compartment, immediately behind the aircleaner
assembly.
Should the transponder key rolling code not match the
PCM’s calculated code, the PCM immobilises the
engine by disabling the fuel and ignition systems.
While visually siCELar , the MY2002 Frontera V6 PCM is
not interchangeable with the Holden GEN III V8 PCM.
When installing a new PCM, ensure that the correct
PCM is fitted to the vehicle. Refer to the latest parts
listing for PCM part number identification.
Note: A repl ac em ent PCM m ust b e p rogrammed. Re fer
to Section 0C-1 - Service Programming System. Once
programmed, the ICU and the PCM must be linked for
correct ope ratio n. Refer to System Prog ramming in this
section.
Starter Motor Relay
The starter motor relay is located in the engine
compartment Main Fuse & Relay Box. One side of the
relay solenoid windings are connected ICU pin B1. Pin
B2 of the ICU is connected to ground.
When the ignition key is in the crank position, and the
correct si gn als have been rece ived by the both ICU an d
the PCM, the ICU will provide the path to ground
energising the relay windings.
Engine Start Sequence
Before the syst em will all ow engi ne oper ation, the foll owing sequ ence of d ata transfe r and code evalu ation mu st take
place:
1. When the ignition is turned ON, ICU supplies a high frequency (133kHz) AC voltage signal to the key via the
antenna.
2. The transponder code is transmitted to the ICU.
3. The ICU checks the transponder code and enables the Immobiliser Relay.
4. The PCM generates and transmits a RANDOM code to the ICU.
5. The ICU receives the RANDOM code from the PCM and transmits the code to the transponder.
6. The transponder calculates a ROLLING code based on the RANDOM code.
7. The transponder transmits the ROLLING code to the PCM via the ICU
8. The PCM compares the transferred rolling code with its calculated rolling code.
9. If both the calculated and transferred codes match, the PCM enable the fuel and ignition systems.
10. The en gine cann ot be s tarted durin g the data tr ansfer an d code ev aluation proc ess. If any of the a bove s teps are
unsuccessful, all relevant engine functions remain disabled.
System Pr ogramming
Programming of the Immobiliser system is performed with TECH-2 when:
• The Immobiliser Control Unit is replaced.
• The Immobiliser Control Unit is reset.
• The PCM is replaced.
• Addit ion al ign iti on ke ys are requi re d.
• An ignition key has been lost.
Prior to commencing the programming sequence, the technician will require:
• The Vehicle Identification Number.
• The vehicle security code from Holden TAS
• The mechanical key number.
To enable the completion of the programming sequence, the technician will require:
• Permission from TIS 2000
Security Data
The following codes/data are stored in the ICU reference memory during vehicle production:
• The Vehicle Identification Number.
• The vehicle security code.
• The mechanical key number.
• Engine type
• Transponder code/s
The secur ity c od e c an not b e d ele ted or al tered with TECH -2. T he trans po nder c od e/s an d en gin e ty pe are p ro cess ed
internal ly only and are n ot displ ayed on T ECH-2. T he Vehic le Identi fication Nu mber and m echanic al key n umber are
stored as further information for vehicle identification and can be displayed on TECH-2.
Security Code
The 4-digit security code prevents unauthorised programming and access to the data in the ICU via TECH-2. The
security code is programmed into the ICU.
Programming the Security Code
New Immobiliser Control Units do not contain a programmed security code. If the ICU is replaced, the security code for
that vehicle must be obtained, and then programmed into the ICU with TECH-2.
Replacement of the Immobiliser Control Unit (ICU)
Due to the comple x nature of the coded signals transmitted between the key and the ICU, it is necessary to replace
both existing ignition keys when the ICU is replaced.
Resetting of the Immobiliser Control Unit (ICU)
Resetting of the ICU m ay nece ssitate repla cemen t of e ither or both exi sting ignitio n key s. Th is s ituati on is most like ly
to occur if the ICU is swapped from one vehicle to another.
System Pr ogramming
Replacement of the PCM
Once programmed to the vehicle Immobiliser system, the PCM cannot be removed and used in another vehicle. The
is no PCM reset procedure available at this point in time - the Service Programming System (SPS) required for
resetting a PCM does not apply to current Jackaroo and Monterey.
Loss of a Transponder Key
If a transponder key is lost, all transponder codes in the Immobiliser Control Unit must be erased to prevent
unauthori sed use. Thi s will ens ure that, whi lst the 'lost' key will allow acc ess to the v ehicle, i t cannot b e used to star t
the vehicle .
After erasing all existing codes, the transponder codes of the remaining keys and the new transponder key can be
programmed.
NOTE:
• Programming Approval must be obtained from TIS, using the `Enable Programming" option, before either
control unit or transponder key programming is performed.
• Once Pr og ra mming Approval h as been obtain ed, T E CH-2 wi ll all ow f ive pr og ra mm ing ope ra tio ns. On ce al l five
programming operations have been used, Programming Approval will then have to be obtained again.
• If the five programming operations are not used within 24hrs, they will be cleared from TECH-2, requiring
further Programming Approval to be obtained.

DTC B0007 - No Engine Request
060RA00003
Circuit Description
The PCM transmits an ‘ENGINE REQUEST’ signal to
the ICU when the ignition is turned ON, using the
‘CHECK ENGINE’ Lamp (CEL) circuit.
Condition for Setting the DTC
A DTC B0007 will set within 0.5 secs. of turning the
ignition ON if:
• The ICU does not receive an ‘ENGINE
REQUEST’ signal from PCM.
This condition may be caused by:
• Cicuit interruption between ICU wiring harness
connector B terminal 7 & PCM wiring harness 80-
way red connector terminal S11.
or
• A defective ICU.
NOTE:
1. A DTC B0007 which has been set due to a wiring
harness fault or ICU failure will, in most cases, be
accompanied by a DTC P1626 ‘IMMOBILISER NO
SIGNAL ’ set in the PCM.
2. A DTC B0007 will be set if the ignition switch is
returned to the ‘ON’ or ‘START’ position within 10
seconds of switching the ignition ‘OFF’. A DTC set
in this manner WILL NOT have any effect on the
starting performance of the engine.
3. Should a DTC B0007 be set under condition (2),
when the ignition switch is returned to the OFF
posittion for more than 10 seconds before
restarting, the DTC will be viewed as ‘NOT
PRESENT’. Again, a DTC set under this condition
WILL NOT have any effect on the starting
performance of the engine.
Action Taken When the DTC sets
• The engine will crank, but will not run.
• The CHECK ENGINE Lamp will flash at 4Hz
Condition for Clearing the CEL/DTC
• Using TECH 2, select Clear DTC Information
• A History DTC B0007 will self-clear after 25
consecutive ignition cycles without the fault
recurring.
