GENERAL DESCRIPTION
Two separate theft deterrent systems were introduced on the 1998 UBS Jackaroo and Monterey:
• Illegal Entry Warning - provided by the Anti-theft/Keyless Entry System fitted to Jackaroo SE and Monterey.
• Drive-away theft deterrent - provided on all models by the Engine Immobiliser System.
The basic ce ntr al locki ng syste m is com mon for all UB S SE and Montere y mo del s. The cen tral locki ng sy st em can be
operated by the mechanical keys, the door lock buttons or the remote keypads.
The Illegal Entry Warning System (more commonly referred to as the Anti-theft/Keyless Entry System), can only be
armed or disarmed with either the mechanical keys or the remote keypads.
MY1998 v ehicles were i nitially supp lied with one rem ote keypad per veh icle (During 1999, an additi onal keypad was
supplied on owner request for all MY1998 SE and Monterey models). All subsequent vehicles from MY1999 have
been supplied with two keypads.
LOCKING/UNLOCKING THE VEHICLE
The door Lock/Unlock operation can be performed by one of two control units:
• The Cen tral Loc king Control Unit – part of the Driver Side Front Doo r Master Switch Assembly. This c ontrol unit is
only responsible for the lock/unlock operation when the lock/unlock door switches are used.
• The Anti -theft/Ke yless E ntry Con trol Un it – mounte d in the low er cen tre of the i nstru ment panel. Thi s control unit is
responsible for the lock/unlock operation when either the mechanical key or remote keypad is used, and for the
operation of the alarm system.
Using the Mechanical Key
The Keyless Entry Control Unit responds to the change in state of the lock switches when the mechanical key is turned
in either the driver or passenger door locks. The Keyless Entry Control Unit then commands the door lock actuators to
the appropria te LOCK or UNLOCK position. When the doors are locked, the alarm system will be armed. When
the doors are unlocked, the alarm system is disarmed.
Using The Remote Keypad
Pressing the lock or unlock buttons on the remote keypad will transmit a radio signal to the receiver in the Keyless
Entry Control Unit. This unit then commands the door lock actuators. When the doors are locke d, the alarm system
is armed. When the doors are unlocked, the alarm system is disarmed.
Using The Lock/Unlock Switches
The Lock/Unlock switches in the driver a nd passenger door armrests commun icate directly with the Central Locking
Control Uni t and NOT to the Keyless Entry Control Unit. The Central Locking Control Unit commands the lock actua-
tors to lock or unlock the doors and tailgate in response to Lock/Unlock switch operation.
NOTE:
• Failure of the Anti-theft/Keyless Entry Control Unit will render both the Anti-theft and Keyless Entry systems
inoperative, but the central locking system will still function.
• The groun d circuit for the starter motor relay passes through the Anti-theft/Keyle ss Entry Control Unit. Sho uld the
Control Unit be removed or disconnected, the starter motor will be inoperative.
• The Lock/Unlock switches will not have any effect on alarm system status. If the alarm system is active and the
unlo ck switch in the dr iver or passenger do or is operated, the doors unlo ck and the alarm is triggered, result ing in
the in dicators flashin g and the anti-t heft horn so unding inte rmittently for a 30-second perio d. Similiarly, locking the
doors via these switches will not arm the alarm system
• Unlocking is also possible by pulling one of the door snib buttons upwards (to unlock a door). If the alarm was
armed, the alarm will be triggered! It is not possible to centrally lock all doors by depressing one of the door snibs.
Answer-back Function – MY 1998 & 1999
The anti-theft horn performs an ‘answer-back’ function when the remote keys are used. Locking the vehicle will cause
the anti-theft horn to ‘chirp’ once. Unlocking will result in the anti-theft horn ‘chirping’ twice. Should the driver so desire
the anti-theft horn ‘answer-back’ function can be disabled.
Answer-back Function – MY 2000
The anti-theft horn ‘answer-back’ function was deleted, being replaced by a visual confirmation through the hazard
warning lamp system. The hazard lam ps flash twice when the vehicle is unlocke d, once when the vehicle is locked.
When loc king the ve hicle, pr essing the lo ck bu tton a s econd time wi ll caus e the a nti-th eft horn to ‘chi rp’ onc e, provi d-
ing audible lock confirmation. The hazard lamp ‘answer-back’ function cannot be cancelled.
Dome Light
As an additional night-time safety measure, the dome light is turned ‘ON’ for 30 seconds when the vehicle is unlocked
using the remote keypad.
ARMING & DISARMING THE ANTI-THEFT SYSTEM
Arming and disarming of the anti-theft alarm system can only be carried out by the mechanical keys or the remote key-
pads.
Arming Operation
• Remove the key from the ignition switch.
• Ensure all doors are shut and the engine hood is closed.
• Lock the vehicle with either the mechanical key or the remote keypad.
• 30 seconds after locking the vehicle, the Anti-theft LED will begin to flash.
• The system is now armed with the module monitoring all doors and the engine hood.
Disarming Procedure
• Unlock the vehicle with the correct mechanical key or the remote key.
• If the alarm is sounding, insert the key into the ignition switch and turn the switch to the “ACC” position.
Triggered Operation
Once triggered, the system will:
• Pulse both the anti-theft and vehicle horns at a rate of one pulse per second.
• Flash all indicator lights at a rate of once per second.
• Disable the starter motor relay.
Triggered o perat ion wi ll c ontinue fo r ap proxima tely 30 se co nds. At the end of this pe riod , the s ystem will rearm itself ,
and continue to monitor the relevant circuits.
NOTE:
• Failure of the Anti-theft/Keyless Entry Control Unit will render both the Anti-theft and Keyless Entry systems
inoperative, but the central locking system will still function.
• The groun d circuit for the starter motor relay passes through the Anti-theft/Keyle ss Entry Control Unit. Sho uld the
Control Unit be removed or disconnected, the starter motor will be inoperative.
• The Lock/Unlock switches will not have any effect on alarm system status. If the alarm system is active and the
unlo ck switch in the dr iver or passenger do or is operated, the doors unlo ck and the alarm is triggered, result ing in
the in dicators flashin g and the anti-t heft horn so unding inte rmittently for a 30-second perio d. Similiarly, locking the
doors via these switches will not arm the alarm system
• Unlocking is also possible by pulling one of the door snib buttons upwards (to unlock a door). If the alarm was
armed, the alarm will be triggered! It is not possible to centrally lock all doors by depressing one of the door snibs.
ANTI-THEFT SYSTEM
The vehicle uses an “earth-sensing” system for monit oring of the doors and engine hood status – opening of any of
these items will cause the relevant circuit in the module to be grounded, triggering the alarm function. The remote
keypad, key switches & lock actuators provide the input signals required for arming or disarming the system. As a
further safe guard, the front door locks and tailgate lock incorporate ‘tamper’ switches that will also ground the relevant
circuit, should the lock be forced or ‘pulled’.
The circuit consists of the ignition switch, anti-theft module, anti-theft horn, anti-theft indicator light, front door and
tailgate key switches, door lock switches, courtesy light switches, door lock actuators and engine hood switch.
Components
Control Unit
The Anti-theft control system is incorporated into the
Anti-theft/Keyless Entry Control Unit, which is mounted

DOOR / TAILGATE / HOOD SWIT CHES
Front Door Key Switch
The Front Door Key Switch consists of two components:
•The Detect Switch - which, in conjunction with the
Front Door Lock Key Switch, provides the LOCK/
UNLOCK signal to the Anti-theft/Keyless Entry
Control Unit when the mechanical key is used. A 10
volt signal on pin 13 of the Anti-theft/Keyless Entry
Control Unit is pulled low as the lock cylinder is
turned.
•The Tamper Sw itch - pulls a 10 v olt signal at p in 16
of the Anti-theft/Keyless Entry Control Unit low if the
lock cylinder is forced from the door.
NOTE:
When refitting a Door Key Switch, ensure that the
switch is correctly adjusted as outlined in Section 1D -
Door Locks.
For removal/installation instructions, refer to Section 1D
- Door Locks.
Front Door Lock Key Switch
The Front Door Lock Key Switch supplies the LOCKED/
UNLOCKED signal to both the Anti-theft/Keyless Entry
Control U nit and the F ront Door Loc k & Power Wi ndow
Switch A ssembly wh en either the remote key pad or the
mechanical key is u sed.
A low-voltage signal is applied to pin 5 and 15 of the
Anti-theft/Keyless Entry Control Unit.
• Locking the doors will pull pin 5 low.
• Unlocking the doors will pull pin 15 low.
NOTE:
For removal/installation instructions, refer to Section 1D
- Door Locks.
Engine Hood Switch
The Engine Hood Switch supplies the HOOD OPEN
signal to the Anti-theft/Keyless Entry Control Unit when
the engine hood is either forcibly opened or the hood
release is actuated with the alarm set. This normally
open switch will pull Anti-theft/Keyless Entry Control
Unit pin 12 low when the hood opens.

KEYLESS ENTRY
The basic c entral loc k ing syst em is co mmo n for all UBS
SE and Monterey models. The central locking system
can be operated by the mechanical keys, the door lock
buttons or the remote keypads.
The Keyless Entry system was introduced on MY1998
vehicl es . T he se v ehi cl es w er e i ni tia ll y su ppl ied w ith on e
remote keypad per vehicle (During 1999, an additional
keypad w as supplied, on own er r equ est, for al l MY 199 8
SE and Monterey models). All subsequent vehicles from
MY1999 have been supplied with two keypads.
COMPONENTS
Control Unit
The Keyless Entry circuit is incorporated into the Anti-
theft/Keyless Entry Control Unit, which is mounted in the
lower centre of the instrument panel, and is identified by
a black/beige ABS plastic casing and a green 22-pin
harness connector. Access to the control unit is gaine d
by removing the console and radio surround.
Power
The Keyless Entry Control Unit is powered via the 20
amp ‘Door Lock’ fuse (C-7), located in the I.P. fuse
panel. This fuse must be fitted during pre-delivery
inspect ion of the vehicle. F ailure of the fuse wi ll disabl e
the key-less entry function and door lock operation.
Synchronisation
The Anti-theft/Keyless Entry Control Unit must be
synchronised whenever the variable code from the
keypad is no longer detected by the control unit. This
usually occurs if a keypad button has been depressed
more than 255 times in succession without the Anti-
theft/Keyless Entry Control Unit being able to “adapt”
(i.e. not in the vicinity of the vehicle).
After removing the batteries, the remote control retains
the last variable code for a period of at least three
minutes. If this time is exceeded, the keypad and
control unit may need to be synchronised.
Synchronising Procedure
Turn the ignition “ON”
Within 30 seconds, press either keypad button.
Sucessful synchronisation is confirmed when the door
lock snibs actuate one time.
Remote Keypads
The remote keypad produces a multi-directional radio
signal (314Mhz @ 78dB) to activate the control circuit of
the Keyless Entry Control Unit.
Two remote keypads are supplied with the vehicle. A
maximum of four keypads can be programmed into the
Keyles s Entry Control Unit. Shoul d an attem pt be mad e
to program a fifth keypad, the first keypad code
programmed will be erased.
This variable code pattern has a complex structure to
prevent interception.When activated, each keypad will
produce three signals:
• A fixed code for identification by the control unit.
• A complex variable or “Rolling” code.
• A LOCK or UNLOCK command code.
Power
Each keypad is fitted with two lithium CR2016 battery
cells. Estimated service life of the two cells is at least
two years with an average usage of ten LOCK/UNLOCK
cycles per day.
Range
Minumum range of the keypad is specified at 10 metres,
althou gh this wil l vary with th e actua l operati ng envi ron-
ment (eg, close proximity to either radio or telephone
transmitting towers will reduce the effective range dra-
matically).
Keypad Types
Two part numbers have been issued for UBS Jackaroo
keypads:
8971638910 - Original issue with the commencement of
MY1998 production. Due to the electronic circuit char-
acteristics, it is necessary to depress the keypad but-
tons for at least 0.5 sec. in order for the Anti-theft/
Keyless Entry Control Unit to correcty identify the
request si gna l.
8972255231 - Second issue in September 1999. Fea-
tures revised internal circuitry to reducing keypad button
depression time to about 0.25 sec.
NOTE:
Keypads with the “DENSO” logo on the reverse side are
calibrated for the New Zealand market (304MHz @
78dB) are unsuitable for use with Australian market
vehicles.
Keypad Programming
Three keypad ID program modes are available:
1. ID Code New Registra tio n – erases all
programmed codes and registers new code.
2. ID Code Additional Registration – registers
additional ID codes.
3. ID Code Check – checks how many ID codes
are programmed in the module.
KEYPAD TESTING
As the keypad trans mits a F M radio si gnal, the v ehicle radi o can be used to check the operation of the key pad. The
actual frequency of the keypad may vary from 97MHz to 106MHz. It is best to commence testing with the radio set on
97Hz.
1. Turn the radio ‘ON’ and set the frequency to 97mHz, and the volume control at about ½ level.
2. Hold the keypad against the base of the antenna then press and hold down the keypad ‘lock’ button.
3. If a pulsing signal is heard from the speakers, the keypad is functioning.
4. Should you fail to hear a signal, try 98MHz and so on up to 106MHz.
5. If you have tried all the frequencies without hearing a signal, replace the two CR20 16 lithium cells in the keypad
and repeat the frequency test.

Initial Diagnosis
When diagnosing a vehicle concern, it is important for the technician to have a basic understanding of the operation of
each system and be aware of the correct diagnostic procedures.
The diag nostic pr ocedur es are s pecific for each s ystem. F ailure to follow the correc t procedu re wil l result in lost ti me,
possible replacement of serviceable components and an aggrieved customer.
To determine which system is at fault, the technician must remember three very important points:
1. As the Anti-theft/Keyless Entry Control Unit provides the earth path for the starter motor relay (via the
Immobiliser Relay) a failure in either the Immobiliser System OR the Anti-theft/Keyless Entry Control Unit may
prevent the vehicle from cranking.
2. Except in exceptional circumstances, the Anti-theft Warning/Key-less Entry System cannot prevent the vehicle
from starting.
3. The Eng ine Immobiliser sy stem cannot prev en t the do or s fr om locking or unl ock ing via the r emo te k eypads or
the mechanical key.
Some ini tial ch ecks a nd a basi c knowledg e of the s ystem will assi st the tec hnician to narrow down the area in which
the fault has occurred. For example:
• Vehicle will not lock/unlock with the remote keypads
1. Does the dome light operate when a door is opened?
- If ‘NO’ check Fuse C16 and the dome light switch operation.
2. Does the vehicle lock/unlock with the mechanical key and the driver door switch?
- If ‘YES’ then the central locking system is functioning.
3. Can the alarm system be ‘armed’ with the mechanical key?
- ‘NO’ would indicate a possible incorrect door/engine hood input to the module.
- ‘YES’ would point to a keypad fault or failure of the relevant circuit within the module.
Having determined which system has failed, the correct diagnostic procedures can then be applied:
• Anti-Theft Alarm/Keyless Entry System diagnosis is performed by referring to the charts in this section.
• Engine Immobiliser system diagnosis is performed by referring to the procedures in Section 11 of the UBS Jackaroo
LCRV SIP.
