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

reprogrammed. However, if the engine hasn't been
run since the last programmed start, the fuel-fired
booster heater will not start up the second time so
as to prevent the battery from being discharged.
The length of time required to pre-heat the vehicle
is calculated in the control unit of the fuel-fired
booster heater and is based on two temperature
values:
• Ambient air temperature: this message is taken
from the GEM via the CAN bus.
• Coolant temperature: this is determined via an internal sensor in the fuel-fired booster heater.
The maximum heating time is 30 minutes at an
outside air temperature of -10 °C or lower. The
heating time decreases proportionally with
increasing ambient temperature until the ambient
temperature is between +15 °C and +20 °C. Then
the minimum heating time is 10 minutes. The
parking heater is deactivated at temperatures
above +20 °C.
The sequence for a programmed start of the
booster heater is as follows:
• Two minutes before the start of the maximum heating time the driver information
system/instrument cluster sends an activation
message to the fuel-fired booster heater via the
CAN bus.
• The fuel-fired booster heater calculates the required heating time and, if necessary, sends
a delay request on the CAN bus.
• At the calculated time, the fuel-fired booster heater starts up. The conditions for start-up are:
engine not running and amount of fuel in the
fuel tank is above 14% of maximum.
• When the coolant temperature reaches +30 °C, the control unit of the fuel-fired booster heater
sends a request to switch on the passenger
compartment blower.
• Eight minutes after the programmed switch-off time, the booster heater stops heating mode
and starts a run-on operation to clean the
system's spark plugs.
• Ten minutes after the switch-off time, the post-cleaning operation is complete. The
additional ten minutes run-on time provides
some leeway in case the driver is late arriving.
After a programmed start-up of the booster heater
it is switched off again after the heating time has
elapsed (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.
Whilst the fuel-fired booster heater is in additional
heating mode and/or parking heating mode, the
instrument cluster receives a fuel consumption
signal; this is used to re-calculate the vehicle's
remaining range and fuel consumption data.
Emergency shutoff
In the event of an accident in which the airbags
are deployed, the control unit of the fuel-fired
booster heater receives a message on the CAN
bus from the restraints control module (RCM).
When this message is received, the booster heater
system switches off immediately.
The booster heater control module deactivates the
system and does not respond to further messages
on the CAN bus. The booster heater control module
needs to be activated with WDS.
Component Description
Electric Booster Heater
The electric booster heater consists of three
individual heating elements, which are incorporated
into a single housing. It is controlled by the generic
electronic module (GEM), taking into account the
following factors:

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.
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.

Generator
General information
The powertrain control module (PCM) controls the
alternator charging voltage. The connection
between the PCM and the generator is made via
the control module subnetwork (LIN) bus.
If the load on the alternator is high, the PCM can
increase the idle speed.
The alternator is temporarily deactivated during
engine starting so that the engine drag moment is
minimized and it is reactivated again after the
starting procedure.
The PCM controls the charge control lamp in the
instrument cluster via the controller area network
(CAN) bus.
Smart Charge system
In addition to the familiar functions, the Smart
Charge system also performs the following
functions:
•
Automatic deactivation of non-critical high power
electrical consumers when the battery voltage
is low in order to reduce the level of current
drawn.
• Automatic activation of non-critical high power electrical consumers when the battery voltage
is excessively high in order to protect
components which are sensitive to increased
voltages.
The battery charging current is optimized through
continuous calculation of the battery temperature
and monitoring of the alternator output voltage.
By receiving the forwarded alternator load signal,
the PCM is given early warning whenever an
electric consumer is switched on or off. This means
that the PCM receives information about imminent
changes in the torque drawn by the alternator. By
evaluating this information the PCM can provide a
higher level of idling stability.
The two remaining functions of the Smart Charge
System are controlled by the GEM.
Electrical consumers are switched off due to low
voltage when the GEM determines (on the basis
of the message received from the PCM on the CAN
bus via the instrument cluster) that the battery
voltage has dropped below the threshold.
When the threshold for low battery voltage is
reached the GEM automatically deactivates the following consumers - in this order and with a gap
of 5 seconds between each:
• Electric booster heater (vehicles with diesel
engines)
• Heated exterior mirrors
• Heated rear window
• Heated windscreen
If the battery voltage rises back above the lower
threshold then the GEM re-enables all of the
electrical consumers which were previously
disabled. They then have switched off status and
must be switched back on by the driver.
Electrical consumers are switched on due to
excessively high voltage if the GEM determines
that the battery voltage is above the threshold for
overvoltage and the charge control lamp has been
switched on.
When the threshold is reached the GEM
automatically activates the following consumers -
in this order and with a gap of 5 seconds between
each:
• Heated rear window
• Heated exterior mirrors
• Electric booster heater (vehicles with diesel engines)
• Blower motor
If the battery voltage drops back below the
threshold then the GEM automatically deactivates
any consumers that were switched on. However,
if they were switched on by the driver before the
automatic activation, they will then be switched on
again in turn with a 5-second time interval. G964174en
