SECTION 12Q - TELEMATICS
IMPORTANT
Before performing any Service Operation or other procedure described in this Section, refer to Section
00 CAUTIONS AND NOTES for correct workshop practices with regard to safety and/or property
damage.
1. GENERAL INFORMA TION
The telem atics system has been de veloped usin g some of the most advanced Global Position System (GPS) and
Global System for Mobile (GSM) telecommunications technology 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 Centre (NERC™).
The telem atics system as fitted to V2 Series Models c arries over from the s ystem as fitted to VX Series I Models,
noting the following:
• The telematics module assembly is mounted to a bracket behind the rear seat back.
• The telematics backup battery is mounted to a bracket behind the rear seat back.
• The telematics antenna is mounted to a bracket behind the rear seat back.
Figure 12Q-1 illustrates the locations of components for the telematics system as fitted to V2 Series Models. For
information regarding the telematics system as fitted to V2 Series Models not provided in this Section, refer to
Section 12Q T ELEMATIC S in the VX Series I Service Information.
NOTE: For a full list of services provided by Holden Assist, refer to the Holden Assist Handbook Supplement.

2. PRINCIPLES OF OPERATION
2.1 TELEMATICS MODULE
The telematics module, mounted to a bracket
behind the r ear seat bac k , controls the o perat ion of
the telematics system. The telematics module
consists of a GPS and GSM engine and a Serial
Data Interface. The telematics module interfaces
with other control modules in the vehicle via the
auxiliary serial data circuit normal mode message.
For further information regarding the serial data
bus and normal mode message, refer to
Section 2.2 SERIAL DATA COMMUNICATION in
Section 12J-1 Low Series Body Control Module
or Section 12J-2 High Series Body Control
Module in the VX Series I Service Information.
Tech 2 is also capable of communicating with the
telematics module via the serial data circuit.
Figure 12Q-2
2.2 BACKUP BATTERY
The backup battery (1) is located behind the rear
seat back and is mounted to the same bracket as
the telematics module. The backup battery will
provide power to the telematics module for
approximately 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 c harge. A 3A f use (2) is used to protec t the
backup battery circuitry.
For further information regarding the backup
battery, including the charging circuit, refer to
Section 12Q TELEMATICS in the VX Series I
Service Information.
Figure 12Q-3
2.3 TELEMATICS ANTENNA
The telematics antenna (1) contains both the GPS
and GSM antennas in one unit, and is located on
the rear parcel shelf, under the rear parcel shelf
trim. The antenna has two leads, one for the GPS
antenna and the other for the GSM antenna.
NOTE 1: The area directly above the telematics
antenna should be free from obstructions (e.g.
accessory sun-visors, parcels, hats etc) as they
may adversely affect antenna reception and the
system will not have full functionality.
GSM ANTENN A
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 such
as 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 and any
stored data will be transmitted. The GSM antenna
is connected to the telematics module by a screw-
on Mini-UHF type connector.
Figure 12Q-4
G PS AN TEN NA
The G PS ant enn a re cei ves signa ls f r om s atellit es or bit ing t he e art h a nd tra ns mits these to the t e lematic s module to
determine the vehicle’s position. Signals from at least three GPS satellites must be received to accurately
determ ine th e veh ic le’s t wo dimens iona l (2 D) pos i tion. Signa ls f rom at leas t f our G PS s a tel l ites must be r ec ei ved to
accurately determine th e vehic l e’s t hr ee d imensiona l (3D) position. If s ign als f rom onl y three s at el lit es ar e re c eiv ed,
the telematics module cannot determine the vehicle’s altitude. The GPS antenna must not be obscured by any
objects, such as underground car parks, tunnels, bridges or buildings as any of these may affect GPS reception.
The GPS antenna is connected to the telematics module by a screw-on SMA type connector.
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 satellites
constantly broadcast radio signals. The telematics GPS module compares the amount of time it takes for the
signals from at least three different satellites to reach the GPS module. By converting time into distance, it can
calculate the m odule’s location on earth. T he telematics module receives GPS data, decodes it, and transm its the
vehicle’s locati on vi a SMS when re qu ested b y Holden Ass is t or NERCTM.

2.4 WIRING HARN ESSES
V2 Series ve hicles equipped with the telematics s ystem have specific main and bod y harnesses, and a telem atics
patch harn ess . The telem atic s patch har nes s c onnec t o r 2 (YB178) plugs into th e main harnes s behin d the le f t hand
kick panel trim (view D) and the telem atics patch harness connector 1 (YB177) plugs into the bod y harness at the
bottom of the B pillar (view C). The telematics patch harness is also connected to the telematics module (YR55)
(view B), t he interior rear view mirror (YB186) (view G). T he telematics speaker (view F) is connected to the main
harness connector (YB181).
