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.
