Description
Tandem Master Cylinder
The short-stroke tandem master-cylinder controls two
separate brake circuits which are jointly activated by the
brake pedal. In the event of a major leak in one system, the
other will still function. The two systems are supplied by a
common brake fluid reservoir.
A pressure sensor attached to the master-cylinder provides
the ABS / DSC module with brake pressure information. This
information informs the system how hard the driver is
braking and is used as an aid for the ABS / DSC to achieve
accurate brake pressure control.
Brake Fluid Reservoir
The brake fluid reservoir is mo unted directly on the tandem
master cylinder and secured with a pin. Two stub pipes, on
the base of the reservoir, locate into the primary and
secondary chambers of the tandem master cylinder.
An integral fluid-level switch is incorporated in the reservoir.
If the brake fluid level is low, the brake warning lamp in the
Driver Information Module (D IM) will illuminate and ‘LOW
BRAKE FLUID’ will be displayed in the message center right.

difference between the ideal and actual response within a
tolerance band. This directly influences the forces on the
tires to generate a corrective yaw moment to reduce the side
forces of the tires where appropriate
System Overview
The DSC system embraces capabilities far beyond that of
ABS, or ABS and traction control combined, while relying on
the components of these systems. It also incorporates these
additional sensors for measur ing the vehicle’s motion and
brake system pressure:
Ya w r a t e s e n s o r - located centrally on the transmission
tunnel.
Lateral acceleration sensor - integrated with the yaw rate
sensor.
Steering angle sensor - located on the upper steering
column.
Pressure transducer - located on master cylinder.
The ABS / DSC module supports data exchange with other
vehicle electronic systems via the CAN network; the module
also enables diagnostic interrogation using WDS.
The following components register driver demand and the
ABS / DSC module processes their signals as a basis for
defining an ideal response:
PCM - position of accelerator pedal.
Brake master cylinder pressure transducer - driver’s
braking effort.
Steering angle sensor - position of steering wheel.
There are many supplementary parameters also included in
the processing calculations these include the coefficient of
friction and vehicle speed. The ABS / DSC module monitors
these factors based on signals transmitted by the sensors for:
• Wheel speed
• Lateral acceleration
• Brake pressure
• Yaw rate
Using these parameters, the function of the ABS / DSC
module is to determine the current vehicle status based on
the yaw-rate signal and the slip as estimated by the ABS /
DSC module. It then maintains the vehicle response within
a tolerance of the ‘normal’ behaviour, which is easily
controlled by the driver.
In order to generate the desired yaw behaviour the ABS /
DSC module controls the selected wheels using the ABS
hydraulic system and engine control system. In the event of
engine intervention, the ABS / DSC module calculates the
torque which should be supplied by the engine to the
wheels, and relays this request signal to the PCM which
implements the torque request.
The PCM receives signals from the DSC system via the CAN
bus and reduces engine torque as follows:
• The throttle is positioned to provide the requested engine target torque. • During the transient phase of torque reduction caused by
mechanical and combustion delays, other alternative
torque reduction methods are used to provide a quicker
response.
• The ignition is retarded and / or the fuel is cut-off at the injectors at selected cylinders.
• Ignition and fuelling are reinstated when the engine torque reaches the requested value
Operation Summary
• DSC is switched ‘ON’ when the engine is started
• When the system is operating , the DSC light in the instrument cluster will flash, at the rate of twice a second
• DSC can be switched ‘OFF / ON’ by pressing the DSC switch
• The DSC light in the instru ment cluster will illuminate
continuously when the system is switched ‘Off’.
• ‘DSC OFF’ will be displayed in the message centre right to indicate the system has been switched ‘OFF’
• A malfunction in the traction control system will be indicated to the driver by the following:
• The DSC light in the instru ment cluster will illuminate
continuously
• The message ‘DSC NOT AVAILABLE’ will be displayed in the message centre right
• If vehicle speed control is engaged it will automatically disengage when traction control is operating .
Traction Control
Traction control is a function of DSC, and is operated in
association with DSC. Traction control prevents excessive
wheel-spin at standing starts, or during acceleration. Wheel-
spin is usually caused by ex cessive use of the accelerator
pedal, or slippery, loose or bumpy road surfaces. To prevent
excessive wheel-spin and mainta in vehicle stability such
situations are overcome by the intervention of the traction
control system by:
• Braking the driven-wheel when it starts to slip
• And / or adapting the engine torque to a level corresponding to the traction available on the road
surface.
Functional Description
Traction control uses the ABS electronic and mechanical /
hydraulic hardware with additional valves to control the
braking pressure at the calipe rs. An engine interface also
enables the engine to respond to torque reduction requests
from the traction control. As with ABS, the signals from the
wheel-speed sensors are supplied to the ABS module, where
they are used to calculate the wheel-slip of the individual
wheels. Traction control intervention is initiated if the slip at
one of the wheels is excessive.

Engine Intervention
In the event of wheel-slip the ABS / DSC module calculates
the torque, which should be applied by the engine to reduce
the wheel-slip (this torque does not exceed driver demand).
Engine torque reduction is then requested from the PCM via
the CAN bus. The PCM, in response to these signals, reduces
engine torque by controlling the ignition and fuelling. A
traction control gearshift pattern is automatically selected
within the automatic transmission software whenever
traction control is active.
Brake Intervention
This function operates by increasing the pressure in the
brake caliper of the slipping wheel, by closing the separation
valve and the inlet valve of the non-slipping wheel and
running the modulator pump. This takes fluid from the fluid
reservoir via the non-actuated master cylinder and
pressurizes the brake caliper. The pressure is modulated at
the caliper via the inlet and outlet valves to achieve the
desired wheel-slip target to maximize traction.

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.

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.

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.

Remote Transmitter
The security system allows up to eight remote transmitters to
be used for controlling the system functions.
The remote transmitter come in packs of two. Each
transmitter is associated with a
series of numbers, which are
shown on a label located on the transmitter packaging.
These numbers are required to program the transmitter to a
vehicle.
Key Learning Operations
Using WDS.
1. Select ‘Set up and Configuration’.
2. Select either:
• Transmitter add
• Transmitter Delete
3. Follow the on screen instructions. Type in the Key ID and the Seed numbers when prompted.
4. If adding a transmitter. After programming , point a transmitter at the vehicle
and attempt to lock / unlock the vehicle. If the vehicle
does not lock / unlock, attempt to lock / unlock using
the second transmitter from the pack.
After a successful ‘Transmitter add’ operation delete the
Key ID and Seed numbers taken from the packaging
label.
The remaining Key ID and Seed numbers are for the
remaining remote transmitter. Ensure that they remain
together .
Integrated Passive Anti-Theft
System (IPATS)
Description
IPATS (immobilisation system) is responsible for enabling /
disabling engine functionality. The system is totally passive
and requires no extra inte rvention from the user.
To prevent the engine from starting the IPATS disables the
fuel pumps, injectors, and the crank circuit.
Disarming IPATS
When the ignition key is located in the ignition barrel and
turned to position ‘II’, the key is validated. If successful,
subsequent requests for crank and engine start will be
allowed. If the key validation fa ils, then engine starting will
be prevented.
Arming IPATS
To arm the system the user simply removes the ignition key.
IPATS LED
An IPATS LED is located in the DIM to display the
immobilisation status and DTC’s using flash codes.
Normal behaviour following a su ccessful key read is for the
LED to illuminate for three seconds and then to extinguish.
If the self-test detects any problem with IPATS when the
ignition is turned on, the IPAT S LED will flash at 4Hz for 1
minute. The IPATS LED will then flash one of the following
codes:
Caution
Do not lose the transmitter packaging, with the number
label attached, before progra mming to the vehicle. The
remote transmitters can not be programmed without the Seed and Key ID numbers.
If the CEM is required to be renewed then all remote
transmitters must be renewed as well.
