How to Read the Circuits
Below is a simple guide to what symbols mean on the circuit
diagrams. For some of the symbols there are descriptions as
to how they function.
Wires
Wires vary in size to allow diffe rent current to be carried. For
example a wire with a diamet er of 0.50mm (This is the
diameter of all the internal copper strands together) will
carry 11A (dependant on ambient temperature) whilst a wire
with a diameter of 2.00mm will carry 25A.
Twisted Wires
The ‘figure of 8’ shown on circuits as below denotes a
twisted wire and shows the wires that are twisted together.
A wire generates a certain amount of ‘electrical noise’ when
a current is passed through it. By twisting the 2 wires
together the ‘electrical noise’ is cancelled out on each wire
by the opposing wire. This is used more on sensors and
audio speakers.

Screened and Twisted Screen Wires
The signals through a wire can be affected by externally
generated electrical noise. To reduce the external
interference the wires are placed inside a conductive sleeve.
One end of the conductive sleeve is always open whilst the
other end can be terminated to a ground, to a component,
or left open.

The symbol for the screen is an oval with the wires that are
to be screened inside it. The letters ‘SCR’ define the screen.
Controller Area Network (CAN)
Controller Area Network (CAN) is the wiring between
intelligent modules of the vehi cle. This wiring carries the
electronic data around the vehicle allowing the various
modules and components to interrogate the network and
read their specific data signals.
There are 2 different speeds of network.
Low speed - Transmits at 125,000 bits per second. Mainly
for body controller systems such as seats and doors
High speed - Transmits at 500,000 bits per second. Mainly
for engine management and powertrain associated systems
such as ABS.
All wiring in the CAN is twisted. The twisted wires always
consist of one wire with a black trace in it for the negative
side and one with a brown trace in it for the positive.
High Speed CAN wire
Low Speed CAN wire
The symbol below shows a module or a component
connector with the pin numbers that have CAN wires
coming from them.
‘CAN LS+’ - Low speed CAN positive side
‘CAN LS-’ - Low speed CAN Negative Side
To aid identification of the different speed CAN’s in the
vehicle different colours of wi re have been used, e.g. the
Low Speed Volcano is GB twisted with GN, the High Speed
Volcano is RB twisted with RN.
There is attached on a separate page a list for wire colour
abbreviations and what colour they refer to.

Media Oriented System Transport
(MOST)
A fibre optic carries out a similar function to that of a wire in
that it transmits data signals. The differences being that
where a wire is made up of copper strands in an insulated
sleeve a fibre optic is a plasti c tube with a highly polished
reflective inside surface.
The fibre optic carries the data in the form of a pulse of light,
which is sent via an infrared transmitter and picked up at the
next component in the loop via an infrared receiver. The
light pulse is then converted to an electrical signal that is
used by that module or component.
The CAN sends signals around the vehicle where the
modules or components remove their specific signals. The
fibre optic is in a loop with the module components in that
loop, one fibre goes in and one fibre goes out. This is shown
below.
Connectors
There are 2 types of interconnect shown on the circuits.
Each connector is given a dedicated ‘C’ number. The
number after the dash is the pin number, also known as the
cavity number. The example below is C0582 that when
checked on the attached list refers to the CEM Connector
Cockpit 2 (C3).
The 1st type is shown for a connector t h a t is o n a m o d u l e o r
component with a mating harness connector attached to it.
The 2nd type is shown for a co nnector on a harness with the
mating connector on another ha rness. This is known as an
Inline . Again the above naming convention applies.

The terminals in a connector housing can have a special
coating on them. This coating if required is selected using
the following criteria.
• A specific coating requested by component / system owner.
Or
• The current passing through the terminal.
• The environment the connector is to be situated with respect to temperature.
• The open circuit voltage passing through the terminal at a given.
Depending on the above criteria the coating, if required, can
either be gold, silver, phosphor bronze. Generally tin is the
common plating on the terminals but there are some that are
gold. These are identified in the circuits with the letter ‘ G’
which stands for gold afte r the connector number. An
example of this is shown below.
Splices
A s p l ic e is u s e d w h e re m o r e t h a n 2 w i re s t h a t h a v e t h e s a m e
requirement i.e. they need the same signal and meet in the
same harness. In the example below the Front Position
Lamp-LH and Front Side marker-LH require the same
output signal from the CEM. Therefore the 2 wires for the
lamps are spliced into the output wire from the CEM on the
Forward Harness.
Tracing Spliced Wires
Some splices appear on pages as a wire that goes to one spot
and seems to terminate in space. An example of this is
shown below.
