SECTION I - ELECTRICAL AND INSTRUMENTS

CAUTION:

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. Refer to CAUTIONS,

Section 12M, 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.

PURPOSE

The purpose of this supplem ent is to provide inform ation on the HSV electric al and instrum ent acces sories f itted to

the HSV VT and HSV VS models. The information is designed to supplem ent that given in the Holden VT and VS

Series Service Information CD’s 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 VT or VS Series Service Manual Supplement. References are made throughout this section to Holden

Series Service Information CD’s, to assist in providing information for specific service operations.

of the hoist contacts the side-skirt

INSTRUMENTATION

GENERAL

A special Instrument Cluster designed by HSV is fitted to all HSV VT vehicles , except Manta. The cluster includes a

HSV speedometer with an operating range extending to 250 km/h. The cluster incorporates a mid-grey face, red

needles and warning lines and, when illuminated, green numerals and letters.

SERVICE OPERATIONS

The HSV instrument cluster and the standard Holden VT cluster use the same mounting fixtures and fasteners.

Remove, ser vice and refit the HSV instr ument cluster in ac cordance with the procedures detailed in the Holden VT

Series Service Information CD, refer Section 12C INSTRUMENTS.

ELECTRICAL FACILITIES

The various special HSV options fitted to the VT 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 sum mary of these electrical harnesses is included to facilitate service, repair and retro-fitm ent of

the HSV options.
