ATTENTION
HSV vehicles are equipped with a Supplemental Restraint System (SRS). An SRS consists of seat belt pre-
tensioners (fitted to all front seats), and a driver’s side air bag or a driver’s side airbag AND a passenger’s-
side air bag and left and right hand side air bags. Refer to CAUTIONS, Section 12M of the Holden VY Series
Service Information before performing any service operation on or around SRS components, the steering
mechanism or wiring. Failure to follow the CAUTIONS could result in personal injury or unnecessary SRS
system repairs.

1 Purpose
The purpose of this supplement is to provide information on the HSV electrical and instrument accessories fitted to the
HSV VY models. The information is designed to supplement that given in the Holden VY Series Service Information and
details are given where differences occur between the HSV models, and standard Holden models. A series of instruction
drawings describe the design changes and indicate specific part numbers, fitting instructions and relevant notes for
vehicle servicing.
NOTE
If specific technical data on a HSV model is not
contained in this supplement, obtain data for that
model from the Holden VY Series Service
Information. References are made throughout
this section to Holden Service Information, to
assist in providing information for specific service
operations.
When hoisting (or jacking) HSV models,
ensure that the lifting head of the hoist lifts on
the chassis before the arm of the hoist
contacts the side-skirt

2 Instrumentation
2.1 General
A special Instrument Cluster designed by HSV is fitted to all HSV VY vehicles. The cluster includes a HSV speedometer
with an operating range extending to 260 km/h. The cluster incorporates a white face, red needles and warning lights
and, when illuminated, white numerals and letters. The cluster also consists of 3 multifunction display windows. At key off
the centre window displays the model and build number of the vehicle. The centre window displays the HOSV logo at key
on for a short period.
HSV manual vehicles are fitted with an upshift indicator. This indicator is controlled by the Engine Control Unit and a
Graphic on the Multi Function Display (MFD), in conjunction with an audible indicator and tell tale at the bottom LHS of
the instrument, gives the driver an indication of when to upshift to achieve maximum performance. The shift indicator will
operate:

2.2 Service Operations
The HSV instrument cluster and the standard Holden VY cluster use the same mounting fixtures and fasteners. Remove,
service and refit the HSV instrument cluster in accordance with the procedures detailed in Section 12C Instruments in the
MY 2003 VY and V2 Series Service Information

3 Electrical Facilities
The various special HSV options fitted to the VY range of vehicles often require that special or additional electric
harnesses be installed. Some of these HSV harnesses are fitted during vehicle build-up at the Holden factory and other
smaller harnesses (often called ‘a patch harness’) are fitted at the HSV facility when the electrical option is being
installed. A summary of these electrical harnesses is included to facilitate service, repair and retro-fitment of the HSV
options.
PART No. DESCRIPTION
92081965 Harness ASM – Body Wiring
12H-020601 Harness – VY Binnacle Gauges
3.1 Gauge Binnacle (POD)
HSV vehicles, except Clubsport and Maloo, are fitted with a gauge binnacle POD which houses an oil pressure gauge
and battery voltage gauge.
Refer to Drawing B06-020601 and 12H-020601.
Oil Pressure
The oil pressure gauge takes it’s reading from a Ω180 resistive to ground sender. At OKPa the sender should read
approx 10Ω across the sender terminal to ground. At 500 kPa the sender should read 180 across the sender terminal to
ground. The (Gauge POD) harness circuits are as follows.
Battery Voltage
The battery voltage is taken from the accessories circuit. The gauge should read battery voltage when the key is in IGN
position.
