System Operation
Electric Booster Heater
In diesel vehicles which give off little residual heat,
a booster heater is used to heat the passenger
compartment rapidly in the case of low ambient
temperatures.
If the interior temperature has been set to HI, or if
the heater controls have been switched to the
highest setting, the two-zone air conditioning
system sends an "electric booster heater ON"
request signal to the CAN (controller area network)
via the medium speed GEM bus. If a manual air
conditioning system is installed, the signal is
transmitted via a conventional cable connection.
The GEM switches on the electric booster heater
depending on the following parameters:
• Engine coolant temperature is below 60 °C.
• Ambient air temperature is below 10 °C.
• Sufficient generator capacity is available.
The electric booster heater electronics activate
three output stages as a function of a pulse width
modulated signal PWM (pulse width modulation)
generated by the GEM. The output stages switch
the three heating elements of the electric booster
heater ON or OFF individually, whereby the heating
periods of the individual elements can overlap. Due
to the variable switch-on duration, continuously
variable temperature control is possible. The overall
heating power of the three heating elements is
linearly proportional to the PWM signal. If the PWM
signal is below 10% or above 95%, the electric
booster heater is not activated.
The electric booster heater is switched off when
an engine coolant temperature of 70°C or an
ambient air temperature of 20°C is exceeded.

Instrument Cluster and Panel Illumination
Refer to
Wiring Diagrams Section 413-00, for
schematic and connector information.
Principles of Operation
NOTE: A new instrument cluster must be
configured.
The instrument cluster and panel illumination
consists of dimmable and non-dimmable
illumination. The dimmable panel illumination is
controlled by the panel illumination switch (part of
the headlamp switch), which allows the brightness
level of the backlights to be adjusted dependent
on the customer preference. When the headlamp
switch is in the parking lamps ON or headlamps
ON position, the intensity of the backlighting can
be adjusted using the panel dimmer switch. The
non dimmable illumination allows for full intensity
dependant on the ignition switch position.

Backlighting A.

B. Engine coolant temperature gauge
C. Fuel gauge
D. Speedometer
E. Information display
The dimmable illumination utilizes light emitting
diodes (LEDs) and bulb(s). The following dimmable
components are backlight using LEDs only:
• ashtray
• cigar lighter
• transmission control lever
• heater control panel
• audio unit • navigation system display module
• instrument cluster
• climate control module
• hazard switch
• traction control system disable switch
• right-hand and left-hand heated front seat

Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical
or electrical damage.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible)
before proceeding to the next step.
4. NOTE: If none of the following warning indicators are operating correctly this may
indicate a concern with the central junction
box (CJB). If only one or two of the following
warning indicators are not operating
correctly this may indicate an instrument
cluster concern. Verify the following warning indicators are
working correctly:
• Charging.
• Turn signals.
• Headlamps.
5. If the cause is not visually evident, verify the symptom and refer to the diagnostic tab within
the Ford approved diagnostic tool.
Configuration of the Instrument Cluster
The instrument cluster is a programmable module,
which must be configured by selecting the
Programmable Module Installation Routine on the
Ford approved diagnostic tool.
NOTE: When the new instrument cluster has been
configured with the odometer value, its
configuration cannot be decreased or matched. A
new configuration will result in an increase in the
displayed odometer value by a minimum of two
units.
NOTE: The odometer value must be recorded from
the original instrument cluster before removal.
If the odometer value cannot be obtained from
the original instrument cluster (display failure)
the customer should supply the approximate
value.
The following features will need to be configured
when a new instrument cluster is installed:
• Anti-lock Brake System (ABS)
• All wheel drive
• Keyless vehicle entry
• Electronic power assisted steering
• Trip computer
• Voice control
• Parking aid
• Belt minder
• Safety belt not fastened
• Right hand drive
• Overspeed warning
• Reverse warning
• Turbocharger boost pressure
• Speed control
• Auxiliary heater
• Suspension control
• Washer fluid sensor G1054964en

General Equipment
Ford diagnostic equipment
Principles of Operation
The ultrasonic parking aid system activates when
the ignition switch is turned to the RUN and when
the parking brake is OFF. If a front parking aid
switch is fitted the system will be de-activated and
a light emitting diode (LED) will indicate the state
of the system. A lit LED will indicate that the system
is currently deactivated. The parking aid system
will be disabled if a fault is detected in one of the
four front parking aid sensors, the parking aid
speaker or the parking aid module. An error tone
approximately 3 seconds long will be emitted from
the rear parking aid speaker if a fault is detected.
If the rear parking aid speaker is inoperative the
error tone will sound from the front parking aid
speaker.

Inspection and Verification
WARNINGS: Batteries contain sulphuric acid. Avoid
contact with skin, eyes, or clothing. Also,
shield your eyes when working near
batteries to protect against possible
splashing of the acid solution. In case of
acid contact with skin or eyes, flush
immediately with water for a minimum of
15 minutes and get prompt medical
attention. If acid is swallowed, call a
physician immediately. Failure to follow
these instructions may result in personal
injury.
Batteries normally produce explosive
gases which can cause personal injury.
Therefore, do not allow flames, sparks or
lighted substances to come near the
battery. When charging or working near a
battery, always shield your face and
protect your eyes. Always provide
ventilation. Failure to follow these
instructions may result in personal injury.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical
