6. TORQUE WRENCH SPECIFICATIONS
1. GENERAL INFORMAT ION
The telematics system has been developed using some of the most advanced Global Positioning System (GPS)
and telecommunications technology, Global System for Mobile (GSM) Communications available. The telematics
system provides in-vehicle safety, security and information services by providing a two way, hands free
communication to either the Holden Assist Centre or, in the case of an emergency, to the National Emergency
Response Centr e (NER C™ ) .
Holden Assist provides several services, some of which include remote door unlocking, connection to Holden
Roadside Assistance, Low Battery Alert and Accident Inquiry. In addition it will know if theft of the vehicle is
attempted, c an then tr ack the vehicl e and in c ertain c irc ums tances, r emotel y immobilis e the en gine. F or a ful l list of
services provided by Holden Assist, refer to the Holden Assist Handbook Supplement.
The link betwee n th e vehicl e and the H ol den As sis t Ce ntre or th e Nat ion al Emergency Respons e C entr e us e s GPS
for vehic le location a nd tracking an d the Australi an digital m obile phone n etwork to trans mit and recei ve voice and
SMS (S hort Mess age Serv ice) data. If the v ehicle is outside network coverag e, the link to and from the vehic le will
not be available and no services can be provided. Signal strength may be affected in locations like basement car
parks or tunnels. However, in most cases, as the vehicle emerges from the obstruction or re-enters the digital
phone network area the signal will be available again.
A vehicle equippe d with the telem atics system will be delivered from the vehicle assembly plant to the retail outlet
with the telematics system in the pre delivery mode. During the pre delivery of the vehicle, the telematics module
pre deli very mode must be dis ab led and t he s ervice m ode must be enab led usin g TECH 2. In servic e mode, limited
service will be provided until the customer has signed the terms and conditions document and the customer has set
up the system by pressing the Holden Assist button located in the telematics button pad on the interior rear view
mirror . The Holden Assist operat or will th en disable service m ode and the s ystem will be f ully operatio nal. T he set
up procedure information is provided in the Holden Assist Handbook Supplement.
The telematics module has a built-in diagnostic system that identifies system operational problems and alerts the
driver by illuminating the Red LED in the interior rear view mirror. If the LED is continuously illuminated with the
ignition o n, the tel em atics syst em will not be f unctional and the ca use of the lam p coming on s hould be check ed as
soon as is reasonably possible.

2. PRINCIPLES OF OPERATION
2.1 OPERATING MODES
The telem atics system has six operat ing m odes, Pre Deliver y, Ser vice, Act ive, Sta nd-by, S leep and Batter y Saver.
The purpose of these different operating modes is to minimise the system current draw and allow features to be
enabled or disabled depending on the operating mode.
PRE DELIVERY MODE
In the pr e del iver y mode the s ystem is n ot opera tiona l. T he ve hicle will b e d eliver ed f rom the ass em bly plant to the
dealer with the telematics system in the pre delivery mode. Before the vehicle is delivered to the customer, the
telematic s system mus t be taken out of the pr e deliver y mode us ing TECH 2. Ref er to 4.3 T ECH 2 TEST M ODES
F5: Program, F1: Operating Mode, in this Section. When in pre delivery mode the telematics module will only
communicate with TECH 2, and only when the ignition is ON.
SERVICE MODE
When the vehicle is scheduled to be serviced, the telematics system service mode should be activated. The
custom er may request the Holden Assist C entre to remotely enable or disab le service m ode. A service technician
can also activate or inactivate service mode with TECH 2. Refer to 4.3 TECH 2 TEST MODES F5: Program,
F1: Operating Mode, in this Section.
When the service mode is activated the telematics module will ignore all button presses except for the Holden
Assist button. In addition, the module will not transmit alert messages for unauthorised entry or low battery.
However the module will transmit an airbag activation alert.
ACTIVE MODE
This is the norm al telem atic s s ystem oper ating m ode. In this m ode the telem atic s system is fully function al an d can
mak e and receive cal ls, and transm it data via the GSM net work. The c urrent draw of the telem atics module is this
mode will be approximately 150 mA.
STAND-BY MODE
Two hours after the ignition has been turned off or two minutes after the ignition has been turned off and a door has
been opened and closed, or two minutes after the conclusion of a call while the ignition is off if stand-by mode is
pending, the telematics module will enter stand-by mode. In stand-by mode the GPS, audio and the keypad buttons
are turned off to reduce the standing current of the telematics module.
The telematics module will enter the stand-by mode:
Two hours af ter the ignit ion is turned of f, or two m inutes after the ignit ion has bee n turned off and a door has bee n
opened, or two minutes after the conclusion of a call when the ignition is off if stand-by mode is pending.
The telematics module will be “woken” from the stand-by mode by any of the following:
An incoming message / call.
The ignition is turned on.
Any door is opened.
The alarm is triggered.
The vehicle batt ery is disconnec te d.
A TECH 2 diagnostic request.
SLEEP MODE
The telematics module will enter the sleep mode on request from the Holden Assist Centre or 30 minutes after a
low battery alert has been sent to Holden Assist Centre, or after five days of uninterrupted ignition off. In sleep
mode the telematics module only monitors the inputs required for it to be “woken” from sleep mode.
The system may be “woken” from sleep mode by any of the following:
Any door is opened.
The alarm is triggered.
A battery removal alert.
BATTERY SAVER MODE
The purpos e of the battery saver mode is to lim it the standing curr ent of the telem atics module while s till providi ng
the abilit y to rem otel y unloc k the vehicle. Af ter 24 hour s of no activit y (igniti on on, any door open ed, SM S recei ved,
unauthorised entry alert, low battery alert) the telematics module will enter battery saver mode. In this mode, the
telematics module will switch between sleep mode and active mode. During active mode operation the telematics
module wil l lo g onto t he G S M net work and an y pendi n g remote unloc k SMS mes sages stor ed i n the ne t work will be
received by the telematics module, and the doors will be unlocked. If no SMS messages are received, the
telematics module will return to sleep mode. After four days of this mode operation and no activity, the telematics
module will remain in sleep mode.
2.2 ALERTS
AI R BAG AC TIVATI ON ALER T
If the vehicle is involved in an accident where the airbags and/or the seat belt pre-tensioners are activated, an
“Airbag Activation Alert” message will be transmitted to the Holden Assist Centre. If the Holden Assist Centre
operator is unable to contact the driver via two-way voice communication in the vehicle, or if the driver cannot
respond, the operator will hand the call over to the National Emergency Response Centre, who will then contact the
Police. T he Police m ay then c ontact the am bulance service. F or further inf ormation r egarding the air bag activati on
alert, refer to the Holden Assist Handbook Supplement.
LOW BATTERY VOLTAGE ALERT
If the vehicle battery voltage falls below a preset voltage for longer than 30 minutes, the telematics module will
transmit a “Low Battery Alert” message to the Holden Assist Centre. The low battery alert voltage is displayed in
the TECH 2 data list. For further information regarding the low battery alert refer to the Holden Assist Handbook
Supplement.
BATTERY REMOVAL ALERT
If the vehicle battery is disconnected, (battery voltage less than one volt), the telematics module will transmit a
“Batter y Rem oval A ler t” message to the Hol den As s ist Centr e. For f ur ther inf ormation regardin g the bat ter y re moval
alert refer to the Holden Assist Handbook Supplement.
UNAUTHORISED ENTRY ALERT
If the veh icle entr y deterren t system is trigger ed for lon ger than 20 seconds , the telem atics module will trans mit an
“Unauthorised Entry Alert” message to the Holden Assist Centre. For further information regarding the unauthorised
entry alert refer to the Holden Assist Handbook Supplement.
2.3 HOLDEN ASSIST REMOTE REQUESTS
ENGINE IMMOBILISATION
In the event of the v ehic le being s tolen, it is pos sib le for the N ERC™ to rem otel y imm obilis e the en gine b y s ending
an “immobilise” message to the telematics module. This function can only be activated by the NERC™ under
instruc tion fr om the Polic e. On rec eiving the “ imm obilise” m essage, the telem atics module wil l then turn of f the f uel
pump relay, cutting off the suppl y of fuel to the engine an d command the BCM (via the serial data circuit) to flash
the indicators. The engine will remain immobilised until the “re-mobilise” message is received from NERC™.
There are two types of remote immobilisation:
IMMEDIATE ENGINE IMMOBILISATION
On receiving an “Immediate Engine Immobilisation” message from the NERC™, the telematics module will
imm ediatel y turn off the fuel pum p rela y, cutting of f the supply of f uel to the engin e and com m and the BCM ( via the
serial data circuit) to flash the indicators.
UNDER 10 KPH ENGINE IMMOBILISATION

TELEMATICS BUTTON PAD
The telem atic s button pad is a resistor encod ed switch , which m eans that each b utton has a sep arate and diff erent
value resistor connected to it. The telematics module uses a voltage divider circuit to determine which button has
been pres sed. T he telem ati cs module A158 (r efer Figur e 12K-6) supp lies a 12 vo lt signa l vo ltage to term inal X1- 12
of the rear view mirror connector circuit 2515 (Light Green/Black wire). Whenever a button is pressed the
corres ponding s witch is clos ed and circ uit 2514 ( Dark Gr een/W hite wire) is conne cted to gr ound t hrough a r es istor,
each switch having a different value resistor. The telematics module monitors the voltage on circuit 2514 (Dark
Green/White wire) at terminal X2-9, which will change when any of the buttons are pressed.
EMERGENCY BUTTON
W hen the em er gency button is pr ess ed, t he voltage at ter minal X 2-9 of the telem atic s module will be a pprox i mately
3.8 Volts. The telematics module determines this voltage at terminal X2-9 as an emergency button press. The
telematics module will initiate a voice call to an operator at the National Emergency Response Centre and then
send an SMS m es sage contai ning status and loc atio n data. If the call can n ot be c onnecte d, the telem atics m odule
will imm ediatel y re-attem pt to connect the call a second tim e. If the sec ond attempt als o fails, the un it shall wait for
60 seconds and make a third and final attempt.
If the emergency button is pressed while a Holden Assist call is in progress then the status of the call shall be
upgraded to an emergency call, and the telematics module will not be permitted to terminate the call by pressing
the “End Call / Information” button.
If the emergency button is pressed while the vehicle is outside GSM network range, the telematics module will
enter “Em er gency Call M od e” wher e b y the emergency call reques t wil l b e reta in ed. When contac t is re- es tab lis he d
with the GSM network, the emergency call will be placed immediately.
HOLDEN ASSIST BUTTON
When the Holden Assist button is pressed, the voltage at terminal X2-9 of the telematics module will be
approximatel y 2.3 Vol ts , th e tel ematic s m odule determines this vo lta ge a t ter minal X2- 9 as an H old en Ass ist But t o n
press. The telem atics m odule will initiate a voice ca ll to the call c entre and then send a n SMS m essage c ontaining
status and location data. If the call can not be connected, the telematics module will immediately re-attempt to
connect th e call a second tim e. If the second attem pt also f ails, the un it shall wai t for 60 s econds and m ake a third

2.6 AUDIO SYSTEM INTERFACE
AUDIO SYSTEM AND RHF SPEAKERS
The telematics system uses the vehicle audio
system to provide a means for voice
communication from the Holden Assist call centre.
The telematics m odule als o has the ab il it y to d etec t
if the audio system is not operational, and will
switch from the vehicle audio system to the RHF
speakers, if it detects that the audio system is not
operational.
Whenever the telematics audio is activated the
radio mute signal is also activated and the
telematics module grounds the radio mute circuit
5211 (Yel lo w/B lack wire) c aus in g the cir cuit voltag e
to be pulled low, less than two Volts. This low
voltage is detected by the radio as a mute request
and when received, the audio system will mute.
The volume of the telematics call can then be
adjusted using the audio system volume control. If
the telematics module switches to the RHF
speakers the volume is fixed by the telematics
module.
Whilst the telematics system is not on a call the
audio and m ute requ est f rom the cell ular telep hone
connector will be passed through the telematics
module to the au dio s ystem . W hen a Holden Ass ist
call is active, the telematics module will ignore the
phone audio and transmit the telematics audio to
the audio system.
AUDIBLE TONES
Audible tones are also provided to indicate the
system status and ar e broadc ast via t he speak er to
alert the customer to certain operating conditions.

2.7 BAC KUP B ATTERY
The backup battery (1) is housed in the battery
compar tm ent of the telematics m odule. The backup
battery will provide power to the telematics module
for at least 30 minutes in the event of the vehicle
battery being discharged or disconnected. The
telematics module has a backup battery charging
circuit that maintains the backup battery state of
charge. This circuit also includes an over current
protection device. The telematics module has a
back up battery timer that monitors the time the
back up battery has been in the vehicle.
After the back up battery has been in the vehicle
for 5 years (4 3680 h ours) it has r eached t he end of
its useful life (internal deterioration causing low
charge ac cepta nce) DT C 13 will be s et a nd the red
status LED will be illuminated, for further

2.8 BATTERY VOLTAGE
Battery voltage is applied to the telematics module terminal X2-16 at all times via circuit 740 (Orange/Black wire),
fuse F29 and fusible link F104 (refer Figure 12K-10). If the battery voltage fails below a preset voltage for longer
than 30 minutes, the telematics module will transmit a Low Battery Alert to the Holden Assist Centre. Refer
2.2 ALERTS, Low Battery Voltage Alert in this Section for further information. If the battery is removed the
telematics module will transmit a Battery Removal Alert to the Holden Assist Centre. Refer 2.2 ALERTS, Battery
Removal Alert in this Section for further information.
Figure 12K-10
2.9 B ACKUP BATTERY CHARGER
The telematics module constantly monitors both vehicle batter y voltage and backup battery voltage. The charging
circuit constantl y m onitors the back up battery voltage to determine if the back up battery needs to be charged at a
maximum of up to 300mA.
Figure 12K-11
2.10 SERIAL DATA
The telematics module monitors the auxiliary serial data circuit 1061 (Green/White wire) normal mode message
for the following information: Airbag Deployed this Ignition Cycle from the SRS SDM and Vehicle Speed from
the PCM. For further information regarding the serial data bus and normal mode message, refer
1.2 Serial Data Communication in Section 12J Body Control Module in this Service Information.
If the telematics module receives a “Remote Unlock” message from the Holden Assist Centre, the telematics
module will request the BCM (via the serial data circuit) to unlock the doors. For further information regarding the
BCM door lock operation, refer Section 12J Body Control Module, Central Door Locking Systems in this
Service Information.
If the telematics module receives a “Immobilise” message from NERCTM, the telematics module will then turn off the
fuel pump relay (refer 2.15 Fuel Pump Relay Drive Circuit in this Section) cutting off the supply of fuel to the
engine and re quest the BCM (via the seri al dat a c irc u it ) to flash th e ind icator s . F or f ur ther i nf ormation regar d i ng t he
BCM indicator operation, refer Section 12J Body Control Module, Theft Deterrent System in this Service
Information.
Figure 12K-12
2.11 DRIVER’S DOOR AJAR SWITCH
The telematics module uses the driver’s door ajar input signal to determine if the driver's front door is opened or
closed. W hen the door is o pened, the driver ’s door ajar s witch gro unds term inal X 2-11 of the telem atics module via
circuit 746 (Grey/White wire). This causes the voltage at terminal X2-11 to be pulled low, less than 0.2 Volts
(driver's door open). This low voltage at terminal X2-11 is detected by the telematics module as the driver's door
open input signal. This is one of the inputs the telematics module uses to determine the system operating mode,
refer 2.1 OPERATING MODES in this Section.
Figure 12K-13
2.12 PASSENGER DOOR AJAR SWITCHES
The telem atics module uses this passengers do or ajar input signal to determ ine if any of the passenger door s are
opened or if all passenger doors are closed. If the right hand rear, left hand front or left hand rear door is open,
term inal X2- 1 of th e telem atic s m odule is groun ded v ia cir cuit 745 (White wire). T his c auses t he volta ge at te rm inal
X2-1 to be pulled low, less than 0.2 Volts (if any one of the passenger doors is opened). The telematics module
determ ines th is low vol tag e at t e rminal X 2-1 as the pa s s enger s do or op en in put signal. T his is o ne of the inp uts th e
telematics module uses to determine the system operating mode, refer 2.1 OPERATING MODES in this Sec tion.
Figure 12K-14
2.13 ALARM INPUT (THEFT DETERRENT HORN)
The telem atics module m onitors the theft deterrent ho rn circuit to determine if the alarm has been triggere d. If the
alarm has been triggered, the BCM pulses the vehicles horns at a rate of once per second. To pulse the theft
deterrent horn the BCM supplies 12 Volts to the theft deterrent horn circuit 1149 (Green wire). When the theft
deterrent horn circuit is activated, the voltage at terminal X2-2 of the telematics module is pulled high. The
telematics module determines this high voltage at terminal X2-2 as the theft deterrent system having been
triggered. If the vehicle theft deterrent system is triggered for longer than 20 seconds, the telematics module will
transm it an “Unauthorised Entr y Alert” m essage to the Holden Assist Centre. F or further information regarding the
unauthorised entry alert, refer to the Holden Assist Handbook Supplement.
Figure 12K-15
2.14 TELEMATICS ANTENNA
The telematics antenna (1) contains both the GPS
and GSM antennas in one unit, and is located
under the instrument panel. The antenna has two
leads, one for the GPS antenna and the other for
the GSM antenna.
NOTE: The area directly above the telematics
antenna should be free from obstructions as
they may adversely affect antenna operation
and the system may not have full functionality.
Aftermarket window tinting may also affect the
antenna operation.
GSM ANT ENNA
The GSM antenna is capable of transmitting and
receiving both voice and data signals via the GSM
network. The telematics module uses the GSM
network to transmit and receive voice and data.
Signal strength may be affected in locations like
basement car parks or tunnels. However, in most
cases, as the vehicle em erges fr om the obstruction
or re-enters the digital phone network area the
signal will be available again and any stored data
will be trans m itted. T he GSM antenn a is c onnected
to the telematics module by a plug in type
connector, refer Figure 12K-17 (1).
TECH 2 displays the GSM signal strength in dBm,
which is decibels per milliwatt. When measuring
GSM signal strength, the measurement is
referenced to 1 mW, and as the signal strength is
less than the reference, it is always negative. The
signal strength will range from –113 dBm (poor
signal) to –50 (good signal).
G PS AN TEN NA
The GPS antenna receives signals from satellites
orbiting the earth and transmits these to the
telematics module to determine the vehicle’s
position. Signals from at least three GPS satellites
must be received to accurately determine the
vehicle’s two dimensional (2D) position. Signals
from at least four GPS satellites must be received
to accurately determine the vehicle’s three
dimens iona l ( 3D) positi on. I f signals fr om onl y three
satellites are received, the telematics module
cannot determine the vehicle’s altitude. The GPS
antenna must not be obscured by any objects,
such as under groun d car par ks, tunn els, brid ges or
buildings as any of these may affect GPS
reception. The GPS antenna is connected to the
telematics module by a plug in type connector,
refer Figure 12K-17 (2).
Figure 12K-16
Figure 12K-17
The telematics module uses a principle called triangulation to determine the location of the vehicle. This
principle states that you can determine the location of an object if you know its distance from three known
locations. GPS uses 24 satellites orbiting the earth, the location of each satellite is known at any given time.
The s atellites constant ly broadcast radi o signals and the tel ematics G PS m odule compares the amount of tim e
it takes for the signals from at least three different satellites to reach the GPS m odule. By converting tim e into
distance , it can calcu late the m odules loc ation on eart h. The telem atics m odule receives GPS data, dec odes it,
and transmits the vehicles location via SMS when requested by Holden Assist or NERCTM.

2.15 FUEL PUMP RELAY DRIVE CIRCUIT
The PCM energises the fuel pump relay drive circuit via circuit 465 (Green/White wire), the telematics module
terminals X1.18 circuit 497 (Light/Green wire) and X1.19 circuit 465 (Dark Green/W hite wire). The fuel pum p rela y
drive circuit is grounded through circuit 550 (Black/White wire) at ground location X157_GP2. The telematics
module can immobilise the vehicle by opening the fuel pump relay drive circuit, causing the fuel pump to stop
operating. This function can only be activated by the National Emergency Response Centre (NERC™) under
instruction from the Police. For further information refer 2.3 HOLDEN ASSIST REMOTE REQUESTS, Engine

5. DIAGNOSIS
The information contained in this Section is where to start all system diagnosis. Once you have read and
understood the General Information Section, which contains reference material: wiring diagrams, telematics module
terminal end views and nominal voltages, and component locations. (Remember, this inform ation is for reference;
do not start diagnosis using these pages). Always start diagnosis on the page titled On-Board Diagnostic System
Check . This check first verif ies that the diagnos tic circuits are operati ng properl y and then sends you to the c orrect
chart for diagnosis.
5.1 BASIC KNOWLEDGE AND TOOLS REQUIRED
To us e the Servic e Inf orm ation eff ective ly, you sho uld unders tand the basic theor y of electr ic ity, s eries and par allel
circuits, and voltage drops. You should know the meaning of voltage (Volts), current (Amps), and resistance
(Ohm s) . You shou ld understand what ha ppe ns in a c ircuit with an ope n or s hor t ed wire ( s horte d e ith er to vo lta ge or
ground). You should also be able to read and understand a wiring diagram, refer to Section 12P WIRING
DIAGRAMS in this Service Information.
To perform system diagnosis, the use of a TECH 2 is required. Tech 31 or a Digital Multimeter (DMM) with 10
megohms impedance, a test light, and jumper wires are also required. Please become acquainted with the tools
and their use before attempting to diagnose a vehicle.
Exercise care when taking readings from wiring harness connectors. It is preferred that the back probing method
with individual connectors is employed wherever possible, to avoid terminal damage and subsequent connection
failure. Carrying out wiring checks as directed b y the diagnostic charts, r ather than prob e term inals and connectors
with incor rect s ized multim eter connec tions . Use th e adapt ors containe d in c onne ctor tes t adapt or k it KM- 609. T his
will prevent any possibility of spreading or damaging wiring harness terminals.
Testing of the various systems will also involve gaining access to specific wiring harness connectors. For the
location of these connectors, refer to Section 12P WIRING DIAGRAMS in this S er vice Inf or mation.
Techline
5.2 DIAGNOSTIC PRECAUTIONS
The following requirements must be observed when working on vehicles:
1. Before performing any Service Operation or other procedure described in this Section, refer to
Section 00 CAUTIONS AND NOTES in this Service Inf orm ation for correct workshop practices with regar d to
safety and/or property damage.
2. Disconnect the negative battery cable before removing any system component.
3. Never start the engine without the battery being connected correctly.
4. Never separate the battery from the on board electrical system while the engine is running.
5. When charging the battery, disconnect it from the vehicle's electrical system.
6. Never subject the telematics module to temperatures above 80°C eg. a paint oven. Always remove the
telematics module first, if this temperature is to be exceeded.
7. Ensure that all cable harness plugs are connected solidly and that battery terminals are thoroughly clean.
8. The har ness con nectors are design ed to f it in onl y one wa y, forcing c onnect ors into place is not neces sary i f it
is being ins ta lled with t he proper or i enta tio n. Fa il ur e to take care to matc h the ind ex ing t abs a nd s lo ts to e nsure
the connector is being installed correctly can caus e damage to the connector, the telem atics module, or other
vehicle components or systems.
9. Never connect or disconnect telematics module cable harness connectors when the ignition is switched on.
10. Before attempting any electric arc welding on the vehicle, disconnect the battery leads and the telematics
module connectors.
11. Use only the test equipment specified in the diagnostic charts, since other test equipment may either give
incorrect results or damage good components.
12. All voltage meas ur em ents us ing a vol tmeter m ust use a d igi tal v oltmeter with a n i nter na l impedanc e r at ing of at
least 10 million ohms per volt (10 meg ohms).
13. W hen a test light is spec ifie d, a lo w-power tes t lig ht must be used. Do not use a hig h - watta ge tes t light. W hile
a particu lar brand of tes t light is not sugges ted, a sim ple tes t on any test light will ensure it to be O K for circuit
testing. Connect an accurate ammeter (such as the high-impedance digital multimeter) in series with the test
light being tested, and power the test light-ammeter circuit with the vehicle battery.
If the ammeter indicates less than 3/10 amp current flow (0.3 A or 300 mA), the test light is OK to use.
If the ammeter indicates more than 3/10 amp current flow (0.3 A or 300 mA), the test light is NOT OK to use.
BLOCKING DRIVE WHEELS
The vehicle drive wheels should always be blocked and the parking brake firmly applied while checking the system.
VISUAL/PHYSICAL INSPECTION
A careful visual and physical inspection must be performed as part of any diagnostic procedure. This can
often lead to fixing a problem without further steps. I nspect all electrical wires for correct routing, p inches, cuts, or
disconnections. Be sure to inspect wires that are difficult to see. Inspect all the wires for proper connections,
burned or chafed spots, or contact with sharp edges or hot exhaust manifolds. This visual/physical inspection is
very important. It must be done carefully and thoroughly.
5.3 DIAGNOSTIC CHART DESCRIPTION
The diagnostic charts are designed to provide fast and efficient means of fault location for all functions associated
with the te lematics m odule. Each diagnos tic chart use s 2 pages; a chart on th e right side pag e, and a facing pag e
on the left side page. The left side "facing page" contains pertinent information and circuit diagrams. The chart
steps are explained by the corresponding numbered paragraph on the left side facing page.
When diagnosing any problem, always begin with the On-Board Diagnostic System Check. The On-Board
Diagnostic System Check will lead you to the other charts. DO NOT GO DIRECTLY TO A SPECIFIC CHART or
false diag nosis and re placem ent of ser viceable parts c ould result. After a f ault is correc ted and all DTCs have been
cleared, repeat the On-Board Diagnostic System Check to assure that the proper repairs have been made.
The box at the top of the left page contains a circuit diagram showing the components involved in each circuit.
Immediately below the box is a brief circuit description. On the facing right hand page a troubleshooting chart for
diagnosing conditions. Step numbers on the right-hand page next to the action boxes in the chart relate to the
items in the Test Description on the left-hand page. These items provide an explanation of each test in the chart.
The facing right hand page also contains a three quarter view of the connectors that are listed in the diagnostic
charts.
The appropriate step in any of the trouble shooting chart will instruct you either to make a specific repair or to
continue diagnosis. If further diagnosis is needed, the step will specify where to continue.
The Yes or No column in any diagnostic chart will instruct you either to make a specific repair or to continue
diagnosis. If further diagnosis is needed, the Yes or No column will specify where to continue.
If the condition is intermittent, the trouble shooting chart will direct you to the diagnostic aids on the facing page.
This Section gives suggestions for diagnosing intermittent conditions and explains how some faults can occur.
Remember, charts are for solving active conditions, not intermittent conditions.

5.4 STRATEGY BASED DIAGNOSTICS
The strategy based diagnostic is a uniform approach to repair all Electrical/Electronic systems. The diagnostic flow
can always be used to resolve an Electrical/Electronic system problem and is a starting point when repairs are
necessary. The steps below are defined to instruct the technician how to proceed with a diagnostic process. Steps
below also refer to step numbers found on the Strategy Based Diagnostic chart.
1. Verify the Driver Concern: To verify the driver concern, the technician should know the normal operation of
the system.
2. Preliminary Check: Conduct a thorough visual and operational inspection, review the service history, detect
unusual sounds or odours, and gather diagnostic trouble code information to achieve effective repair.
3. Service information System Check(s): System checks verify proper operation of the system. This will lead
the technician in an organised approach to diagnostics.
4. Check Bulletins and Other Service Information: This should include, Service Techlines, All Dealer letters,
and Service T r ain ing Pu bl ications.
5. Service Diagnostics (Paper/Electronic)
5.1 Current DTC Stored: Follow the designed DTC chart exactly to make an effective repair.
5.2 Symptom, No DTC: Select the symptom from the diagnostic charts and follow the diagnostic paths or
suggestions to complete the repair, or refer to the applicable component/system checks in this Service
Information.
5.3 No Published Diagnostics: Analyse the com plaint and develop a plan for diagnostics. Utilise the wiring
diagrams and theory of operation.
Call Technical Assistance for similar cases where repair history may be available. Combine technician
knowledge with efficient use of the available service information.
5.4 Intermittent faults: Conditions that are not always present are intermittent. To resolve intermittence,
perform the following steps:
5.4.1 Observe history DTCs, DTC modes and Freeze Frame data if available.
5.4.2 Evaluate the symptoms and conditions described by the driver.
5.4.3 Use a check sheet or other method to identify the circuit or electrical system component.
5.4.4 Follow the suggestions for intermittent diagnosis found in the service documentation.
The TECH 2, Tech 31 and a DMM have data capturing capabilities that can assist in detection of intermittents.
5.5 Vehicle Operates As Designed/No Trouble Found: This condition exists when the vehicle is found to
be operating normally. The condition described by the driver may be normal. Verify against another
vehicle that is operating norm ally. T he condition may be interm ittent. Contact Technical Assistance if the
concern is common. Verify the complaint under the conditions described by the driver before releasing
the vehicle.
6. Re-examine the Concern: When the complaint cannot be successfully found or isolated, a re-evaluation is
necessary. The complaint should be re-verified and could be intermittent or normal as per step 5.3 or 5.5.
7. Repair and Verific ation Test s: After is olating th e cause, the r epair sho uld be m ade. Then v alidate for pr oper
operation and verify that the symptom has been corrected. This may involve road testing or other methods to
verify the complaint has been resolved under the following conditions:
• Conditions noted by the driver.
• If a DTC was diagnosed, verify a repair by duplicating conditions present when a DTC was set.

5.5 ON-BOARD DIAGNOSTIC SYSTEM CHECK
After the visual/physical vehicle inspection, the On-Board Diagnostic System Check is the starting point for all
diagnostic procedures or finding the cause of a system malfunction or failure.
All Diagnostic procedures must always begin with the ON-BOARD DIAGNOSTIC SYSTEM CHECK.
Diagnostic procedures must begin with the On-Board Diagnostic System Check, which represents an organised
approach for identifying system problems.
The ON-BOARD DIAGNOSTIC SYSTEM CHECK makes an initial check of the system, then will direct the
technician to other charts in the Service Information. It must be used as a starting point for all procedures. The
entire diagnostic section in the Service Information is set up in a specific order, that is, the ON-BOARD
DIAGNOSTIC SYSTEM CHECK will lead the technician to other charts, and those charts may lead to still other
charts. THE SEQUENCE MUST BE FOLLOWED. The telematics module uses many input signals and controls
many output functions. If the correct diagnostic sequence is not followed, incorrect diagnosis and replacement of
good parts may happen.
Diagnostic charts incor porate diagnos is procedures using a TECH 2 wher e possible. T ECH 2 is a sm all hand-hel d
computer in itself. Its job is to give information to a technician about what is happening in the system.
The Data Link Connector (DLC) is used by the as sembl y plant to perf orm end of line tests. T his c onnector c an also
be used by technicians to monitor certain inputs and outputs as detected by the telematics module. The TECH 2
reads and displays the information (serial data) supplied to the data link connector from the telematics module.
The correct procedure to diagnose a problem is to follow three basic steps.
1. Are the On-Board Diagnostics working? This is determined by performing the On-Board Diagnostic System
Check. Since this is the starting point for the diagnostic procedures or finding the cause of a failure, always
begin here.
If the On-Board Diagnostics are not working, the On-Board Diagnostic System Check will lead to a diagnostic
chart to correct the problem. If the On-Board Diagnostics are working correctly, the next step is:
2. Is there a Diagnostic Trouble Code stored? If a diagnostic trouble code is stored, go directly to the numbered
diagnostic trouble code chart. This will determine if the fault is still present. If no diagnostic trouble code is
stored, then:
3. Observe Serial Data transmitted by the telematics module: This involves reading the TECH 2 information.
TECH 2 Information and the meaning of the various displays can be found in the Service Information. Typical
data readi ngs under a part icular oper ating cond ition c an be found on th e TECH 2 Data page . If the actual data
does not match the typical data, then refer to the specific diagnostics for that data parameter.
5.6 DIAGNOSTIC TROUBLE CODES
W hen the telematic s modul e detects an op erating param eter which is outside its calibr ated va lues it will set a DT C
and stored this DTC into its memory as a current DTC. When a current DTC is set the Red Status LED may be
illum inated whe ne ver the ig nition is on.
The s ix mos t recent DT Cs that hav e occur red will be l ogged into t he telem atic s m odule m em ory into a t able k nown
as the “DTC List”. The DTC list can contain histor y data for the six most recent DTCs. Therefore, if m ore than six
DTCs are set, only hist ory data for the last six will be t racked. T hat is, the ol dest DT C will be rem oved from the list
regardless of its position within the list.
NOTE: Once a DTC has been removed from the “DTC List” it is maintained in the memory of the telematics module
as a History DTC, however there will be no DTC history data available for this DTC.
The DTC history data contained in the “DTC List” is as follows:
List Position Position within the list numbered from 1 to 6.
DTC Number The DTC number is the number used to identify a particular fault condition.
Occurrence Count
(0 to 255) The Occurrence Count is the number of tim es the particular fault condition has been
detected.
History Count
(0 to 255) The History Count is the number of ignition cycles that have occurred since the fault
was last detec ted. A cou nt of 0 indicates th e fault has occur red on the curr ent igni tion
cycle, while a count of 255 indicates that the fault occurred 255 or more ignition
cycles ago.
Algorit hm s for detec ting ea ch f ault conditi on and s ettin g the corr espond ing DT C var y. However, a p articu lar DTC is
only set once per ignition cycle. When a DTC is set, the following occurs:
• If the DTC does not exist in the DTC List, it is inserted into the list at the first vacant location with the
Occurrence Count set to 1 and the History Count set to 0. In the event of the DTC List being full, the oldest
DTC will be removed from the list. The Histor y Count determines the age of a DTC List entry. T he item in the
list with the highest History Count will be removed to make space for the new DTC.
• If the DT C already exists in the DT C List, then the Occurrenc e Count will be incremented ( up to 255, at which
point it is no longer incremented). Each time the DTC is set, the History Count is cleared.
This ensures th at the six most rec ent fault condit ions are tr acked. T he Occ urrenc e and Hist ory Counters provide a
means of determ ining how often the f ault has occ urred, and how long it has be en since th e fault las t occur red. For
instance, if the DTC Occurrence Count is 1, and the History Count is 201, then it can be de termined that the fault
condition existed only once, and it happened 201 ignition cycles ago (and has not been detected since). Another
exam ple would be an Occ urrence Count of 4 and a Histor y Cou nt of 0. This woul d indicate that t he fault has bee n
detected a total of four times, and that it was detected on the current ignition cycle.
The DT Cs are not rem oved f rom the list u nless six newer f ault condi tions occ ur pushin g the oldest f ault off the list,
or they are cleared using TECH 2.
NOTE: Once a DT C has been rem oved fr om the “ DTC List” it is m aintained in th e telem atics module m emor y as a
History DTC, however there will be no DTC history data available for this DTC.

CIRCUIT DESCRIPTION
The telem atics antenn a contains both the GPS and GSM antennas in one unit, a nd is under th e instrum ent panel.
The antenna has two leads, one for the GPS antenna and the other for the GSM antenna. The GSM antenna is
capable of transmitting and receiving both voice and data signals via the GSM network. The telematics module
uses the GSM network to transmit and receive voice and data. Signal strength may be affected in locations like
basement car parks or tunnels. However, in m ost cases, as the vehicle emerges from the obstruction or re-enters
the digital phone network area the signa l will be availa ble again and an y stored data will be transm itted. The G SM
antenna is connected to the telematics module by a push on type connector.
TEST DESCRIPTION

strength can vary from -113 (poor Signal) to –50 dBm (good signal), as low signal strength could cause call
dropout. The vehicle should be moved to a location that has a better GSM signal and the signal strength
checked again.

CIRCUIT DESCRIPTION
W hen the em er gency button is pr ess ed, t he voltage at ter minal X 2-9 of the telem atic s module will be a pprox i mately
3.8 Volts, the telematics module determines this voltage at terminal X2-9 as an emergency button press. The
telematics module will initiate a voice call to an operator at the National Emergency Response Centre and then
send an SMS m es sage contai ning status and loc atio n data. If the call can n ot be c onnecte d, the telem atics m odule
will imm ediatel y re-attem pt to connect the call a second tim e. If the sec ond attempt als o fails, the un it shall wait for
60 seconds and make a third and final attempt.
If the emergency button is pressed while a Holden Assist call is in progress then the status of the call shall be
upgraded to an emergency call, and the telematics module will not be permitted to terminate the call by pressing
the “end call / information” button.
If the emergency button is pressed while the vehicle is outside GSM network range, the telematics module will
enter “Em er gency Call M od e” wher e b y the emergency call reques t wil l b e reta in ed. When contac t is re- es tab lis he d
with the GSM network, the emergency call will be placed immediately.

THEFT DETERRENT HORN CIRCUIT
Figure 12K-116
CIRCUIT DESCRIPTION
The telem atics module m onitors the theft deterrent ho rn circuit to determine if the alarm has been triggere d. If the
alarm has been triggered, the BCM pulses the vehicles horns at a rate of once per second. To pulse the theft
deterrent horn the BCM supplies 12 Volts to the theft deterrent horn circuit 1149 (Green wire). When the theft
deterrent horn circuit is activated, the voltage at terminal X2-2 of the telematics module is pulled high. The
telematics module determines this high voltage at terminal X2-2 as the theft deterrent system having been
triggered. If the vehicle theft deterrent system is triggered for longer than 20 seconds, the telematics module will
transm it an “Unauthorised Entr y Alert” m essage to the Holden Assist Centre. F or further information regarding the
unauthorised entry alert, refer to the Holden Assist Handbook Supplement.

AUDIO SYSTEM INTERFACE
Figure 12K-125
CIRCUIT DESCRIPTION
The telematics system us es the veh icl e au di o system to provide a means f or vo ic e co m munication f r om the Holden
Assist call centre. The telematics module also has the ability to detect if the audio system is not operational, and
will switch from the vehicle audio system to the RHF speakers, if it detects that the audio system is not operational.
Whenever the telematics audio is activated the radio mute signal is also activated and the telematics module
grounds the radio mute circuit 5211 (Yellow/Black wire) causing the circuit voltage to be pulled low, less than two
Volts. This low voltage is detected by the radio as a mute request and when received, the audio system will mute.
W hilst the telematic s system is not on a call t he audio and m ute request f rom the cellu lar telephone c onnector will
be passed through the t elematics module to the audio system. When a Holden Assist call is active, the telematics
module will ignore the phone audio and transmit the telematics audio to the audio system.
