Headlamp Levelling (HID Only)
The ‘Automatic Dynamic He adlamp Levelling System’
consists of:
• An Automatic Dynamic Headla mp Levelling System ECU
• A level sensor for the front suspension
• A level sensor for the rear suspension
• A bi-polar stepper motor mounted in the housing of each headlamp
The Automatic Dynamic Headlamp Levelling System
prevents the dipped beam dazzling oncoming road traffic by
varying the angular position of the dipped (and main beam)
headlamp units relative to the position of the vehicles
suspension.
Static condition - Compensates for boot or occupant load
condition.
Dynamic condition - Compensates for suspension
movements due to acceleration and deceleration. The
sensitivity of the system is dependent on vehicle speed and
the rate of change of the vehicle speed.
High amplitude low frequency inputs such as those caused
by potholes are filtered out to desensitise the system in
constant speed situations.

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.

In a correctly protected circuit, the fuse is placed ‘ Inline’
between the power source in this case the battery and the
lamp. If the lamp goes ‘short circuit’, a massive current will
begin to flow and the fuse will fail causing an open circuit.
The battery and wiring are protected from over current
damage.
Below is the fuse symbol as shown on the circuit diagrams.
The number above the fuse symbol is the fuse number;
allocated to this fuse. The number below the fuse symbol is
the rating.
Resistors
A resistor is an electronic component that by way of its
construction reduces the current flowing through it. A
resistors unit of measure is the Ohm.
The diagrams below show a resi stor and a variable resistor.
Variable Resistors
A variable resistor works in the same manner as a normal
resistor but the resistance values can fluctuate. The
construction of a variable resi stor depends upon its use and
environment.
One example is for the fuel tank level sensor. The tank full
level is 10 ohms and the tank empty level is 204 ohms, the
resistance will vary between 10 and 204 ohms depending on
how much fuel is in the tank.
Lamps
Below is the symbol for a light bulb, shown below the
symbol is the power of the bulb in watts.
Switches
There are numerous of types of switch, several of examples
are shown below.
Normally Open Switch
2 Position Switch
3 Position Switch
Motors and Pumps
The same symbol is used for a pump or a motor, the
description differentiates between them.

Motor
Diodes
The simplest way of describing a diode is ‘a non return
valve’. The current will flow through the diode from the
anode to the cathode, due to the construction of it though
current cannot come back. Diodes are used to reduce the
possibilities of ‘back feed’. This is where current comes
through the circuit the wrong way for one reason or another.
Below is the circuit symbol for a diode.
Light Emitting Diode (LED)
The light emitting diode (LED) works on the same principal
as the diode. The main difference is that in the
manufacturing process one of the materials is replaced by
another. This replacement mate rial has certain properties
that when a certain voltage passes through it glows.
Transistor
A transistor in simplistic term s is a switch with no moving
parts. The ‘switching’ is controlled by electronics and
currents etc. rather than a physical switch being operated.
Below is the circuit symbol for it. The example shown below
is one of the most common basic type used called a
‘Bipolar’.
Field Effect Transistor (FET)
A field effect transistor (FET) is, in simplistic
terms, a switch with no moving parts. The
‘switching’ is controlled by electronics and
currents etc. rather than a physical switch
being operated. The main difference
between this and the type of transistor shown above is this
one operates using a magnetic field.
Earth / Ground
For an electrical current to ‘flow’ around a circuit it has to
start from a power source and go to an earth / ground. If
there are any breaks in this circ uit then current will not flow,
this is called an ‘Open circuit’
There are 2 types of earth, Signal Earth and Chassis Earth,
these are referred to sometimes as a Quiet Earth and Noisy
Earth respectively.
Some sensors for example specify a Signal / Quiet Earth.
While components such as pumps and motors can have a
Chassis / Noisy Earth. The reason behind this is that pumps,
motors and the like can generate ‘electrical noise’ by the
way of their operation. Some of this ‘electrical noise can be
transferred through wires, it is this ‘electrical noise’ that can
have an adverse effect on sensor signals and affect the
control readings.
Keeping Signal / Quiet and Chassis / Noisy
earths separate reduces th e effect of ‘electrical
noise’ being transferred from component to
component.
This symbol is a standard symbol for earths.
On the circuit diagrams some earths are shown as eyelets
with the description of Earth-**** next to it, the earths also
comply with the 4 digit C number. An example of this is
shown below.
