USING THIS PUBLICATION

Health and safety

Always follow health and safety guidelines, specifically those detailed in the Workshop
Manual.

Using this publication

The information provided in this publication is for use only by competent, qualified auto-
electricians. Good product knowledge is assumed, as well as the ability to access and use
recommended test equipment and other reference material provided.

Test equipment and other reference material

The information in this publication should be used in conjunction with the recommended test
equipment; refer to Workshop Manual. Other reference material includes: Technical Service
Bulletins (TSB) and the Workshop Manual.

The Electrical Reference Library (ERL) may also prove useful since it provides detailed
connector information.

Battery disconnection and reconnection

It is imperative that any information relating to battery disconnection and reconnection is
followed; refer to the appropriate sections in the Workshop Manual.

Fault Diagnosis

Always use the recommended test equipment for correct and reliable fault diagnosis, refer to
the Workshop Manual.

Harness Repair

Repairs should only be undertaken for connectors where a Service Repair Kit is available;
refer to the appropriate Electrical Reference Library (ERL).
Note: Fibre Optic circuits cannot be repaired; refer to the Workshop Manual.

Section numbering

The sections in this publication are ordered to match the Global Outline numbering system
as found in the current Workshop Manual. The Power and Ground distribution circuits can be
found under section 414-01, BATTERY, MOUNTING AND CABLES.
Note: Where circuit diagrams show more than one sub-system, the circuit will be
located in the section that carries the first-named sub-system, for example: Starting and
Charging will be located under section 303-06 Starting System, since 'Starting' is the first-
named sub-system.

Circuit sheet numbering

The figures in brackets to the left of the page number indicate a circuit sheet number and the
total number of sheets per circuit, for example (01 / 05) represents sheet 1 of 5.

Understanding the circuit diagrams

Components

After each component description, a translation code is displayed in brackets, for example:
Starter relay (R102), Engine control-module (ECM)(D131). The codes can be ignored.
Note: A dotted outline indicates that the component identified is not shown in its
entirety.

Connectors

Connectors and header joints are identified by their corresponding connector number with a
numbered suffix to indicate the pin-out detail of the wire, i.e. C0292-1 identifies connector
292, pin number 1. Wire insulation colours are listed in a table at the end of this section.
Where wires have a predominant colour with a secondary colour tracer, the main colour is
identified first, i.e. WH-BK - white with a black tracer.

Wire length (Power and Ground Distribution only)

The wire length (in millimetres) is displayed after the colour and cross sectional area; for
example, SR,0.35,480. In this example, the figure, 480 indicates the approximate position of
the harness splice is 480mm from connector C2335.

Line Types

Crossed wires as illustrated above show an example of how a twisted pair of wires may be
represented on the circuits.

The arrows illustrated above show an example of the page break symbols, identifying that
the circuit continues at the corresponding letter on the sheet number indicated.

The cup and ball symbol represents the male and female halves of connector. Most
connectors plug directly into a component but some are wired directly to the component
using a ‘flylead’ as with C0503 above.

Ground points

Ground points are identified with an eyelet symbol and a connector number, except where
components are grounded through its fixings, when only the eyelet is shown.
