Gene ra l Informat i on
The Engine Immobiliser System is designed to provide ‘Drive-away’ protection by electronically disabling the fuel
system and the starter motor relay. It is a passive system, requiring no action on the part of the driver other than
removing the ignition key from the switch.
When the i gnition s witch is turne d ‘ON’, a p rocess of data tra nsfer takes plac e between the transponde r type ignit ion
key, the Immobiliser Control Unit and the Diesel Cut-off Solenoid (DDS-1) Module.
If any transmitted data is incorrect or missing, the ICU prevents Immobiliser Relay operation - disabling the starter
motor, and th e DDS-1 Mod ule wi ll s hu t o ff the fu el supp ly to th e inj ec tor p ump . W he n t he eng ine ha s be en sh ut down
for more than twelve se conds, b oth the reques t and the im mobiliser signal cha nge on the ne xt ignition k ey 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 Trouble
Code (DTC) is stored in the ICU. It should be noted that the indication of an Immobiliser system fault is the only
function of the ‘CHECK ENGINE’ lamp on the 4JB1T system.
System Components
The main system components are:
• Transponder Key
• Coil Antenna
• Immobiliser Control Unit (ICU)
• Coil Antenna
• Immobiliser Relay
• DDS-1 Module & Fuel Cut Solenoid Valve
• 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 operating signal is provided cordlessly 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.
NOTE: The Immobiliser Key for the 4JB1T diesel
engine differs INTERNALLY from that fitted to
MY2002 4JH 1-TC eng ined vehicles . When pro viding
a replacement or additional Immobiliser Key, refer
to the latest parts listing for correct part number
identification.
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 Contol Unit (ICU) is located bolted to
the cross-beam behind the RH lower instrument panel.
The ICU is powered at all time s from Fuse EB-2 (Horn)
and receives an ignition ‘ON’ signal from Fuse CB-2
(Engine).
Communication from the ICU to the DDS-1 Module is on
the DDS-1 signal wire (ICU pin 10 to DDS-1 pin 1).
NOTE: If the ICU and DDS-1 are replaced at the
same time, the ICU MUST be programmed BEFORE
the Immobiliser function of the DDS-1 can be
activated.
NOTE: The 4JB1T diesel engine ICU differs from
that fitted to other Holden Light Commercial
Vehicles. When installing a new ICU, ensure that the
correct part is fitted to the vehicle. Refer to the
latest parts listing for ICU part number
identification.
DDS-1 Module
The DDS-1 Module is mounted on the rear of the
injector pump. The Mo dule trans mits a 10-volt signal to
the ICU. When the ignition is turned ON with a valid
transponder key, the ICU’s code generator will pulse the
10-volt signal to ground. The DDS-1 Module’s Signal
Comparator compare the coded signal generated by the
ICU to that pre-programmed into it’s memory. If both
codes are identical, the injector pump Fuel Cut Solenoid
Valve wi ll be e n ab l ed , a llowi ng f uel to fl o w to t h e in je ct or
pump.
A mis-match between the ICU generated code and the
DDS-1 Module code, or a failure occur in the
Immobiliser system, the Fuel Cut Solenoid Valve will
remain disabled, preventing the engine from running.
Note: A replacement DDS-1 must be linked to the ICU
for correct operation. Refer to System Programming in
this section.
Immobiliser Relay
The Immobiliser Relay is located in the engine
compartment Main Fuse & Relay Box. One side of the
relay solenoid windings is connected to power via the
Engine Fuse CB-2, and the other side connected ICU
pin 14. Pin 7 of the ICU is connected to ground.
When the ignition key is in the crank position, and the
ICU has received a valid transponder key signal, the
ICU will provi de th e path to groun d, ene rg ising the relay
windings.
When enabled by the ICU, the Immobiliser Relay allows
the starter motor relay to be energised.
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 Immobilser Relay.
4. The DDS-1 transmits a 10 volt signal from pin 1 to the ICU pin 10.
5. The ICU Code Generator will pulse the 10 volt signal to ground in a pre-programmed sequence.
6. The DDS-1 Module’s Signal Comparator compares the coded signal generated by the ICU to that programmed
into it’s memory.
7. If both co des are identical , the DDS-1 will enabl e the injecto r pump Fuel Cut Solenoi d Val ve, allowing fue l to flow
to the injector pump.
System Programming
Programming of the Immobiliser system is performed with TECH-2 when:
• The Immobiliser Control Unit is replaced.
• The Immobiliser Control Unit is reset.
• The DDS-1 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 f rom 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 TEC H-2. T he trans po nder cod e/s an d en gin e ty pe are p ro ce ssed
internal ly only and are n ot displ ayed on T ECH-2. T he Vehic le Identific ation 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 repla ce
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.
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 Approva l h as been obta in ed, TE CH- 2 will all ow f iv e prog ra mm ing ope ra tio ns . On ce al l fi ve
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.

Diagnostic Trouble Codes
Current DTC's
The engine will not run when any current DTC is logged.
• The DDS-1 Module disables the fuel system.
• The ICU inhibits starter motor operation by disabling the Immobiliser relay.
History DTC's
When the fault has been repaired, the engine will operate normally and the current DTC becomes a History DTC.
History DTC's are stored in an EEPROM. This type of memory storage means the codes are not cleared when the
battery is disconnected.
• History codes may be cleared from the system memory by TECH 2.
• A History DTC will self-clear after 25 consecutive ignition cycles without the fault recurring.
