Auxiliary Climate Control – Overview
Initial start-up of the fuel-fired booster
heater
The fuel-fired booster heater needs to be filled
before being taken into operation for the first time.
Activation of the fuel pump for the fuel-fired booster
heater is controlled by the Ford diagnostic unit.
Lockout
Flame sensor
If the flame goes out independently during
operation of the booster heater, a restart is carried
out. If the booster heater does not ignite within 90
seconds of fuel delivery or if the flame goes out
within 15 minutes of starting, a lockout will be
implemented by the flame sensor.
Lockout can be cancelled by switching the booster
heater off then on again, although this may only
be repeated at most 2 times.
Overheating sensor
In the event of overheating (water shortage, poorly
ventilated coolant circuit), the fuel supply to the
booster heater is interrupted and a lockout occurs.
After the cause of the overheating has been
eliminated, the booster heater can be started again
by switching it off and on, if the coolant temperature
is below 70°C. If the booster heater overheats ten
times in a row, the control unit will be locked.
Unlocking the control unit
Delete the fault memory of the fuel-fired booster
heater after eliminating the cause of the fault using
the Ford diagnostic unit.

Boost heat mode
When the engine is running, the booster heater
helps the engine to heat the passenger
compartment at low ambient temperatures.
When the coolant temperature reaches 30 °C, the
control unit transmits a switch-on signal for the
passenger compartment blower via the CAN bus.
When the coolant temperature drops, the blower
remains on until the temperature reaches 20 °C
whereupon it is deactivated.
The fuel tank must be filled to at least 14% for the
system to be switched on. If the fuel level drops
below 8% then the system is switched off.
In boost mode, the fuel fired booster heater is only
switched on if all of the following criteria are met:
• Engine speed above 500 rpm. The fuel fired booster heater is not allowed to start up while
the engine is being cranked; this prevents a
shut-down due to low voltage if the battery
charge is low.
• Ambient temperature below 5 °C.
• Fuel level above 14% of total capacity.
• Function is active on the trip computer menu.
One of the following conditions is sufficient to
switch off the booster heater in boost heat mode:
• Engine speed below 500 rpm.
• Ambient temperature above 11 °C.
• Function is active on the trip computer menu.
• Fuel level below 8% of total capacity.
Programmable fuel fired booster heater
The programmable fuel fired booster heater has
two operating modes:
• Instant start
• Programmed start
The heater status is displayed on the instrument
cluster display. The parking heater mode is controlled via a menu in the message centre. The
fuel fired booster heater can be activated and
deactivated via the message centre. (If set to 'Auto'
the system is activated, if set to 'Off' the system is
completely deactivated)
Immediate start-up of the booster
heater
This function enables the fuel-fired booster heater
to be switched on manually when the engine is not
running. This function is activated via the menu on
the driver information system.
The ignition key must be in the II" position before
this menu can be accessed. The timer function of
the booster heater remains active when the ignition
key is in position "0".
After an immediate start-up of the booster heater
it is switched off again after 30 minutes (or if the
fuel level in the fuel tank drops below 8%). The
booster heater stops within 2 minutes of the engine
starting. This leaves enough time to check whether
the switch-on conditions for boost heat mode have
been met, thus preventing the booster heater from
having to switch off and switch back on again. The
heater can be switched off manually at any time
from the menu.
Programmed start-up of the booster
heater
The driver can use a menu to adjust the time at
which the vehicle is to be pre-heated. The following
options are available:
• Time setting. One or two times can be
programmed for each day of the week. It is
possible to program days either individually or
together in groups (Mon-Sun/Mon-Sat/Mon-Fri).
• Time and data setting
With the first option, the fuel-fired booster heater
will start repeatedly without needing to be G1066982en

Lockout can be cancelled by switching the booster
heater off then on again, although this may only
be repeated at most 2 times.
Overheat Sensor
The overheating sensor enables the fuel-fired
booster heater module to determine the coolant
temperature, protecting the heater from
overheating. The overheating sensor is installed
next to the coolant temperature sensor under a
cover on the top of the fuel-fired heater.
In the event of overheating (lack of water, poorly
ventilated coolant circuit), the fuel supply to the
heater is interrupted and a lockout occurs. After
the cause of the overheating has been eliminated,
the heater can be restarted by switching it off and
on again, if the coolant temperature is below 70°C.
If the heater overheats ten times in a row, the
control unit is locked.
ECT
The fuel-fired booster heater module uses the
temperature sensor to determine the coolant
temperature, which it then uses to set the starting
and stopping time. The coolant temperature sensor
is installed next to the overheating sensor under a
cover on the top of the fuel-fired heater. Water pump The coolant pump is located on the holder for the
fuel-fired heater on the bulkhead in the rear of the
engine compartment. The coolant pump is driven
by a built-in electric motor and circulates the
coolant in the engine cooling system. The delivery
rate for the pump is 820l/h at a delivery pressure
of 0.1 bar.
Fuel pump
The fuel required for the fuel-fired heater is taken
from the fuel system by a fuel pump fitted in the
fuel tank and is delivered to the heater via a fuel
line.
The fuel pump is an electric piston pump which
meters the corresponding fuel volume for the
fuel-fired heater according to a cycle set by the
fuel-fired heater module.

System Operation
Instrument Cluster
The instrument cluster contains analog displays
as well as warning and control lamps for displaying
the system status; in addiiton, there is an LCD
indicator field for driver information.
The instrument cluster receives the following
signals from the PCM via the high speed CAN
(controller area network) Bus (HS-CAN):
• Vehicle speed – The PCM receives the necessary signalsfrom the ABS (anti-lock brake system) wheel
sensors from the ABS control unit on the
HS-CAN.
• Engine Coolant Temperature
• Engine oil pressure.
• Engine speed
The instrument cluster receives the following
signals from the GEM via the medium speed CAN
Bus (MS-CAN):
• Ambient temperature
• Brake fluid level
• Handbrake control
• Door latch control
• Liftgate latch control
• High beam control
• Headlamp flasher control
• Direction indicator control
The fuel level signal is sent by the two fuel level
sensors in the fuel pumps in the semitrailer tank,
which is wired to the instrument cluster. The
sensors are connected in series, and the total
resistance is determined from the two individual resistors. The instrument cluster converts the raw
fuel level signal into a damped fuel level value.
The odometer shows the total distance travelled
by the vehicle and is based on the same signal as
is processed for the daily mileage counter. The
value is recorded by the instrument cluster and
stored in a protected EEPROM (Electronically
Erasable Programmable Read Only Memory) area.
This area is a memory protected against
manipulation. If the instrument cluster detects an
error in this memory area, e.g. through damage,
the driver is notified with the "Odometer error"
message.
Message center
The message center is operated using the left-hand
switch on the steering column.
The SET/RESET button is activated to select a
submenu and change the settings. If signal tones
have been activated, a short acoustic signal will
sound each time a button is pressed.
By turning the rotary switch, the different menu
displays can be scrolled through or a setting
selected.
In this display, the navigation system can also
display direction and distance information.
In addition, safety and warning messages can be
displayed in this system, such as "Coolant
overheating", "Engine system error" or "Washer
fluid level too low". In addition to a safety message,
a general warning light (red/yellow) lights up.
