ITEM DESCRIPTION
1 Fuel Fired Booster Heater (FFBH) fuel pump (diesel installation shown, petrol installations similar)
2 FFBH receiver (vehicles with timed climate control only)
3 FFBH (vehicles with timed climate control)
4 FFBH coolant changeover valve (vehicles with timed climate control)
5 Coolant tube connector (vehicles without timed climate control)
6 FFBH (vehicles without timed climate control)
7 FFBH (NAS only)

Depending on model specification and market, the vehicle may incorporate auxiliary heating in the form of a Fuel Fired Booster Heater (FFBH). The FFBH boosts the temperature of the engine coolant supplied to the climate control assembly and, where fitted, the auxiliary climate control assembly.

Fuel for the FFBH is taken from the vehicle fuel tank, through a fuel line attached to the fuel pump module. A FFBH fuel pump supplies the fuel at low pressure to the FFBH. In the FFBH, the fuel is burned and the resultant heat output is used to heat the engine coolant, which is circulated through the climate control assembly and, where fitted, the auxiliary climate control assembly, by a FFBH coolant pump.

FFBH operation is automatic while the engine is running. Where timed climate control is incorporated, the FFBH can be selected to operate (depending on the ambient air temperature) while the vehicle is parked using the touch screen or a remote control.

Vehicles with timed climate control also incorporate:

  • A FFBH receiver for communication with the remote control
  • A FFBH coolant changeover valve that allows the climate control coolant circuit to be isolated from the engine coolant circuit to reduce the warmup time of the passenger compartment.

NOTE:

NAS vehicles are not fitted with an operational Fuel Fired Booster Heater (FFBH).

The Fuel Fired Booster Heater (FFBH) is installed in the engine compartment, on a support bracket attached to the rear of the right suspension housing. It is connected in series with the coolant supply to the climate control assembly. A flying lead on the FFBH connects it to the vehicle wiring. The FFBH consists of the following:

  • A Fuel Fired Booster Heater Control Module (FFBHCM)
  • A combustion air fan
  • A combustion chamber
  • A heat exchanger
  • A coolant pump
  • An air intake hose and muffler
  • An exhaust pipe and muffler.

Fuel Fired Booster Heater Control Module

The Fuel Fired Booster Heater Control Module (FFBHCM) controls and monitors operation of the Fuel Fired Booster Heater (FFBH) system. Power for the FFBHCM is provided by a permanent feed from the QCCM (Quiescent Current Control Module) integrated in the RJB (Rear Junction Box). A Local Interconnect Network (LIN) bus connection provides the communication link between the FFBHCM and the HVAC (HVAC Control Module). The FFBHCM also has:

  • A ground connection
  • Power feed and ground connections with the FFBH coolant pump
  • A power feed connection with the FFBH fuel pump
  • A signal line connection with the FFBH receiver (vehicles with timed climate control only).

 

Combustion Air Fan

The combustion air fan regulates the flow of air to the heater so as to ensure correct combustion. If the heater is operational while the engine is stopped or the heater enters the control idle phase, the air fan will continue to run in order to cool the combustion chamber in readiness for the next required start. The operation of the fan may be noticed during this process. This is perfectly normal.

Combustion Chamber

The combustion chamber is located in the heat exchanger casing and the combustion air fan casing. The fuel feed pipe of the combustion chamber extends up through the cover of the combustion air fan. A glow plug is installed in the combustion chamber to provide the ignition source for the fuel:air mixture.

Heat Exchanger

The heat exchanger transfers heat generated by the combustion chamber to the engine coolant. An overheating temperature sensor and a surface temperature sensor are installed in the heat exchanger and connected to the Fuel Fired Booster Heater Control Module (FFBHCM). The FFBHCM uses the temperature inputs to control system operation.

Fuel Fired Booster Heater Coolant Pump

The Fuel Fired Booster Heater (FFBH) coolant pump is an electric pump attached to outboard end of the FFBH support bracket. The pump intake is connected to either the heater coolant feed from the engine (vehicles without timed climate control) or to the FFBH coolant changeover valve (vehicles with timed climate control). A hose, which incorporates a bleed screw, connects the outlet of the coolant pump to the coolant inlet of the FFBH.

The coolant pump runs continuously while the FFBH is in control idle or active operating modes. While the FFBH is inactive, coolant flow is reliant on the engine coolant pump.

Air Intake Hose and Muffler

A canister type muffler and filter is incorporated into the air intake hose.

Air Intake Hose and Charcoal Canister

Depending on specification some petrol vehicles are fitted with an extended air-intake hose and activated charcoal canister.

Exhaust Pipe and Muffler

The exhaust pipe and muffler directs exhaust combustion gases to atmosphere below the vehicle, to the rear of the right front wheel arch and towards the center of the vehicle. Exhaust vapor may be visible when the Fuel Fired Booster Heater (FFBH) is running, depending on atmospheric conditions. Under normal operating conditions, the exhaust vapor will subside once the FFBH has achieved “Power status” and the exhaust pipe has reached normal operating temperature.

Under certain circumstances, for example after heater replacement or the disconnection of the fuel or coolant circuits, smoke may be visible from the general vicinity of the heater rather than the outlet of the exhaust. This may be as a result of residual fuel or coolant on the exhaust or heater body as a result of the service procedure. Under these circumstances, the heater must be run continually for 15-20 minutes until there are no signs of excessive smoke.

ITEM DESCRIPTION
1 Electrical connector
2 Fuel Fired Booster Heater (FFBH) coolant pump
3 Fuel Fired Booster Heater Control Module (FFBHCM)
4 Connection to heater
5 Connection to engine cooling system

The Fuel Fired Booster Heater (FFBH) only uses the FFBH coolant pump. The FFBH coolant pump is used to pump the coolant through the heater system. The FFBH coolant pump is controlled by the HVAC Control Module through the Fuel Fired Booster Heater Control Module (FFBHCM).

Fuel Fired Booster Heater Control Module (NAS only)

The Fuel Fired Booster Heater Control Module (FFBHCM) controls and monitors operation of the Fuel Fired Booster Heater (FFBH) coolant pump. Power for the FFBHCM is provided by a permanent feed from the QCCM (Quiescent Current Control Module) integrated in the RJB (Rear Junction Box). A Local Interconnect Network (LIN) bus connection provides the communication link between the FFBHCM and the HVAC (HVAC Control Module). The FFBHCM also has:

  • A ground connection
  • Power feed and ground connections with the FFBH coolant pump.

 

FUEL FIRED BOOSTER HEATER FUEL PUMP

E148870

The Fuel Fired Booster Heater (FFBH) fuel pump is installed in a rubber mounting attached to a crossmember under the rear floor, above the fuel tank. The pump is a self priming, solenoid operated plunger pump. The Fuel Fired Booster Heater Control Module (FFBHCM) in the FFBH outputs a PWM (Pulse Width Modulation) signal to control the operation of the pump. When the pump is de-energized, it provides a positive shut-off of the fuel supply to the FFBH.

CHARCOAL CANISTER (PETROL VEHICLES ONLY)

E191181

Depending on vehicle specification, an extended air-intake hose and activated charcoal canister may be fitted to the Fuel Fired Booster Heater (FFBH).

The canister functions as both an acoustic silencer and, under certain operational and environmental conditions, captures and recycles the evaporative emissions exhausted by the FFBH.

The canister is a serviceable item and can be replaced if blocked or damaged. A Diagnostic Trouble Code (DTC) will be stored in the Body Control Module/Gateway Module (BCM/GWM) if a restriction is present. This can then be verified by removing the canister and performing an FFBH activation test.

FUEL FIRED BOOSTER HEATER COOLANT CHANGEOVER VALVE (VEHICLES WITH TIMED CLIMATE CONTROL ONLY)

E148871

Where fitted, the Fuel Fired Booster Heater (FFBH) coolant changeover valve is attached to a bracket on the underside of the FFBH. The FFBH coolant changeover valve is a normally open solenoid valve installed between the supply and return sides of the heater coolant circuit. When de-energized, the FFBH coolant changeover valve connects the heater coolant circuit to the engine coolant circuit. When energized, the FFBH coolant changeover valve isolates the heater coolant circuit from the engine coolant circuit.

Operation of the FFBH coolant changeover valve is controlled by a power feed from the HVAC (HVAC Control Module).

FUEL FIRED BOOSTER HEATER RECEIVER (VEHICLES WITH TIMED CLIMATE CONTROL ONLY)

E148872

The Fuel Fired Booster Heater (FFBH) receiver translates the FFBH remote control radio signals, relayed from the TV antenna amplifier, into a voltage output to the FFBH. When a request for timed climate control is received, the FFBH receiver outputs a battery power feed to the FFBH unit. When a request to switch off timed climate control is received, the FFBH receiver disconnects the power feed.

The FFBH receiver has a permanent power feed from the Body Control Module/Gateway Module Assembly (BCM/GWM) and is connected to the television antenna amplifier by a coaxial cable. For additional information, refer to:Antenna (415-01 Information and Entertainment System – Vehicles With: InControl Touch Pro, Description and Operation).

FUEL FIRED BOOSTER HEATER REMOTE CONTROL (VEHICLES WITH TIMED CLIMATE CONTROL ONLY)

E148873

 









ITEM DESCRIPTION
1 ON switch
2 Antenna
3 Light Emitting Diode (LED) operating indicator
4 OFF switch
5 Battery cover

NOTE:

Avoid touching the antenna when operating the ON or OFF switch. Covering the antenna will have an adverse affect on the transmitting range.

The Fuel Fired Booster Heater (FFBH) remote control enables the timed climate control program to be activated and deactivated from outside the vehicle. The remote control has an approximate range of 100 m (328 ft). There is no need to point the remote control at the vehicle. Press and hold the ON button for approximately 2 seconds. The Light Emitting Diode (LED) illuminates green to confirm that a timed climate program has been initiated. The LED continues to flash for a few seconds to indicate that the timed climate is active.

The timed climate program continues for 20-30 minutes, after which it switches off automatically to prevent the vehicle’s battery from discharging. It also turns off automatically if the engine is started.

The LED indicator signals various states and conditions for the timed climate as follows:

  • Illuminates green when the ON button is pressed and then quickly flashes green, to indicate that heater operation has been requested.
  • Illuminates green followed by red when the OFF button is pressed, to indicate that the heater has been requested to shut down.
  • Illuminates green and then quickly flashes red when either the ON or OFF button is pressed, to indicate that there is no communication with the receiver. This normally occurs if the vehicle is too far away.
  • Illuminates green and then slowly flashes red when either the ON or OFF button is pressed, to indicate that there is an error.
  • Flashes red when either the ON or OFF button is pressed, to indicate that the timed climate remote battery needs replacing.

NOTE:

The timed climate control program will only operate once per engine start to maintain battery condition.

Replacing the Fuel Fired Booster Heater Remote Control Batteries

 

E157943

 

With the front of the Fuel Fired Booster Heater (FFBH) remote control facing upwards. Press down on the rear of the battery cover and push completely off to reveal the battery compartment. Remove the old battery. Install a new, unused 3 volt CR2032 battery and make sure that the correct polarity is maintained. Align and push the cover back to the original position.

NOTE:

The battery should be inserted with the positive side facing upwards.

Fuel Fired Booster Heater Remote Control Pairing

Each Fuel Fired Booster Heater (FFBH) remote control must be ‘paired’ to the FFBH receiver to enable communications. Each remote control has a unique identification number which is stored by the receiver. The receiver can store up 4 remote control identification numbers. If a fifth remote control is paired to the receiver, the receiver will overwrite the first paired remote control number.

Pair a remote control to the vehicle, as follows:

  1. Remove fuse F1 (5A) or F27 (5A) (depending on market specification) from the Body Control Module/Gateway Module Assembly (BCM/GWM).
  2. Wait for a minimum of 5 seconds.
  3. Replace fuse F1 (5A) or F27 (5A) (depending on market specification) in the BCM/GWM then, within 5 seconds, press and hold the remote control OFF switch.
  4. A successful pairing is indicated by the remote control Light Emitting Diode (LED) illuminating red for 2 seconds.

NOTE:

The pairing process relies on the Fuel Fired Booster Heater (FFBH) receiver having the power supply removed and then the power supply re-instated. The fuse method is the easiest method but it can also be achieved by battery disconnection or removal of the harness connector from the FFBH receiver.

 

FUEL FIRED BOOSTER HEATER (NON NAS)

NOTE:

The NAS petrol engine vehicles are not fitted with an operational Fuel Fired Booster Heater (FFBH).

Operation of the Fuel Fired Booster Heater (FFBH) is controlled by a status message from the HVAC (HVAC Control Module) to the Fuel Fired Booster Heater Control Module (FFBHCM). A similar status message, from the Fuel Fired Booster Heater Control Module (FFBHCM) to the HVAC, advises the HVAC of the current operating status of the FFBH.

While the engine is running, if the ambient air temperature is less than 7°C (45°F) (Diesel) or 1°C (34°F) (Petrol) and the engine coolant temperature is less than 75°C (167°F) the HVAC changes the status message from ‘heater off’ to ‘supplemental heat’. The FFBHCM then changes the status message it sends the HVAC to ‘supplemental heat’ and starts the FFBH.

If the engine is started and the FFBH is requested. The HVAC closes the recirculation flap for the first 4 minutes or until the vehicle road speed exceeds 16 km/h (10 mph). The HVAC opens the recirculation flap to enable the ingress of fresh air. This feature is over ridden if the MAX demist switch on the Integrated Control Panel (ICP) is selected or if the HVAC detects a risk of misting of the windshield.

The FFBH will not start, or will discontinue operation, if any of the following occur:

  • The FFBHCM is in the error lockout mode (see DIAGNOSTICS below).
  • The engine stops running for approximately 4 seconds. The time delay is included for stall detection.
  • The HVAC receives a ‘fuel cut-off’ message from the Body Control Moduel/Gateway Module (BCM/GWM) on the High Speed (HS) Controller Area Network (CAN) comfort systems bus. The BCM/GWM sends the message if it receives a crash signal from the RCM (Restraint Control Module). For additional information, refer to:Airbag and Safety Belt Pretensioner Supplemental Restraint System (501-20B Supplementary Restraint System, Description and Operation).
  • The HVAC receives a low fuel level message from the BCM/GWM on the HS CAN comfort systems bus.
  • The Quiescent Current Control Module (QCCM) integrated into the Rear Junction Box (RJB) disconnects the power supply to the FFBH. For additional information, refer to:Battery and Cables (414-01 Battery, Mounting and Cables, Description and Operation).

If the FFBHCM does not start the FFBH, or discontinues operation, the status message to the HVAC remains at, or changes to, ‘heater off’.

If the ambient air temperature increases to 10°C (50°F) (Diesel) or 4°C (40°F) (Petrol) or the engine coolant temperature increases to 88°C (190°F) The HVAC cancels supplemental heating, by changing the status message to the FFBHCM back to ‘heater off’. The FFBHCM then cancels FFBH operation and changes the status message to the HVAC to ‘heater off’.

Start Sequence

At the beginning of a start sequence, the Fuel Fired Booster Heater Control Module (FFBHCM) energizes the Fuel Fired Booster Heater (FFBH) coolant pump then operates the following in a preset sequence to start the FFBH:

  • The combustion air fan
  • The glow plug
  • The FFBH fuel pump.

Once combustion has stabilized, the FFBHCM switches off the glow plug. If the FFBH fails to ignite the FFBHCM repeats the start sequence.

Combustion Loads

While the Fuel Fired Booster Heater (FFBH) is running, the Fuel Fired Booster Heater Control Module (FFBHCM) depending on the temperature of the coolant in the heat exchanger cycles between:

  • Power load combustion
  • High load combustion
  • Low load combustion
  • A control idle phase of operation.

The heat output level at low load combustion is 2.3 kW. This rises to 5 kW at high load combustion and 5.2 kW at power load combustion. The FFBHCM transmits the amount of fuel used by the FFBH to the Body Control Moduel/Gateway Module (BCM/GWM), and the FFBH coolant temperature to the HVAC (HVAC Control Module).

Switching Point Temperatures

E157985











SWITCHING POINT TEMPERATURE, ºC (ºF)
ITEM NUMBER DESCRIPTION
1 Power load to high load 65ºC (149ºF)
2 High load to low load 80ºC (176ºF)
3 Low load to control idle 85ºC (185ºF)
4 Control idle to low load 75ºC (167ºF)
5 Low load to high load 65ºC (149ºF)
6 High load to power load 55ºC (131ºF)

The switching point temperatures are for reference only and may vary depending on the fuel type and engine size.

After the start sequence, the Fuel Fired Booster Heater Control Module (FFBHCM) maintains power load combustion until the coolant temperature reaches switching point temperature 1. At this temperature, the FFBHCM decreases the speed of the FFBH fuel pump and the combustion air fan to enable high load combustion. The FFBHCM maintains high load combustion while the coolant temperature remains between switching point temperatures 2 and 6.

At high load combustion the temperature of the coolant will increase or decrease depending on the amount of heat required to heat the vehicle interior. If the coolant temperature decreases to switching point temperature 6, the FFBHCM increases the speed of the FFBH fuel pump and the combustion air fan to full speed, to return to power load combustion. If the coolant temperature increases to switching point temperature 2. The FFBHCM decreases the speed of the FFBH fuel pump and the combustion air fan to enable low load combustion.

At low load combustion the temperature of the coolant will again increase or decrease depending on the amount of heat required to heat the vehicle interior. If the coolant temperature decreases to switching point temperature 5. The FFBHCM increases the speed of the FFBH fuel pump and the combustion air fan to enable high load combustion. If the coolant temperature increases to switching point temperature 3, the FFBHCM enters a control idle phase of operation.

On entering the control idle phase, the FFBHCM immediately switches the FFBH fuel pump off, to stop combustion, and starts a timer for the combustion air fan. After a 90 seconds (diesel vehicles) or 120 seconds (petrol vehicles) cool down period. The FFBHCM switches the combustion air fan off and then remains in the control idle phase while the coolant temperature remains above switching point temperature 4. If the coolant temperature decreases to switching point temperature 4, the FFBHCM initiates a start to low load combustion.

Shutdown

To stop the Fuel Fired Booster Heater (FFBH), the Fuel Fired Booster Heater Control Module (FFBHCM) de-energizes the FFBH fuel pump to stop combustion. The combustion air fan and the coolant pump continues operation for a time, to cool down the FFBH. The cool down time is approximately 90 (diesel vehicles) or 120 (petrol vehicles) seconds.

Diagnostics

The Fuel Fired Booster Heater Control Module (FFBHCM) monitors the Fuel Fired Booster Heater (FFBH) system for faults. Any faults detected are stored in a volatile memory in the FFBHCM, which can be interrogated by Land Rover approved diagnostic equipment via the Medium Speed (MS) Controller Area Network (CAN) comfort systems bus. A maximum of three faults and associated freeze frame data can be stored at any one time. If a further fault is detected, the oldest fault is overwritten by the new fault.

The FFBHCM also incorporates an error lockout mode of operation that inhibits operation to prevent serious faults from causing further damage to the system. In the error lockout mode, the FFBHCM immediately stops the FFBH fuel pump, and stops the combustion air fan and coolant pump after the cool down time. Error lockout occurs for start sequence failures, combustion flameouts, heat exchanger casing overheat and if the primary battery voltage is out of limits.

  • Start failure and flameout: If a start sequence fails to establish combustion, or a flameout occurs after combustion is established, the FFBHCM immediately initiates another start sequence. The start failure or flameout is also recorded by an event timer in the FFBHCM. The event timer is increased by one after each start failure or flameout, and decreased by one if a subsequent start is successful. If the event timer increases to three (over any number of drive cycles), the FFBHCM enters the error lockout mode.
  • Heat exchanger casing overheat: To protect the system from excessive temperatures, the FFBHCM enters the error lockout mode if the heat exchanger coolant temperature exceeds 125°C (257°F).
  • Battery voltage out of limits: Error lockout will occur if the primary battery voltage is outside the limits of 10.5V to 16.0V.

The error lockout mode can be cleared using Land Rover approved diagnostic equipment, or by disconnecting the battery power supply to the FFBH for a minimum of 10 seconds.

TIMED CLIMATE CONTROL

Where fitted, timed climate control provides a comfortable temperature in the passenger compartment of a vehicle parked with the engine off. When timed climate control operates, the passenger compartment is either heated by the Fuel Fired Booster Heater (FFBH) and climate control blower (parked heating) or cooled by the climate control blower (parked ventilation), depending on the ambient air temperature. Parked heating occurs if the ambient air temperature is less than 16°C (61°F). Parked ventilation occurs if the ambient air temperature is 16°C (61°F) or more. To prevent excessive drain on the battery, both parked heating and parked ventilation are automatically de-activated after 30 minutes.

In very cold conditions timed climate control also warms the engine to aid starting. Engine warming occurs if the ambient air temperature is -25°C ( -13°F) or below.

When timed climate control is operating, the Light Emitting Diode (LED) in the AUTO or A/C switch on the Integrated Control Panel (ICP) will flash. If the AUTO switch LED flashes the engine or passenger compartment are being heated. If the A/C switch LED flashes the passenger compartment is being ventilated.

Timed climate control is controlled using either the touch screen or the FFBH remote control.

In order to minimize the potential for odor ingress from the FFBH, the HVAC (HVAC Control Module) will automatically close the recirculation door in the climate control assembly for the first few minutes of FFBH operation when activated by the timed climate control feature.

Touch Screen

The touch screen is used for direct selection of timed climate control or to program one or two ‘on/off’ cycle start-times per day, and one ‘on/off’ cycle start-time further in the future. The programmed start times are stored in the Body Control Moduel/Gateway Module (BCM/GWM). The direct selection and programmed time modes of operation are selected when the engine is stopped and the smart key is in the vehicle. The key can then be removed and the vehicle locked. Any timed event will automatically run without the key inside the vehicle.

At a programmed start time or a direct selection on the touch screen, the BCM/GWM sends a start signal to the HVAC Control Module via the High Speed (HS) Controller Area Network (CAN) comfort systems bus. The HVAC Control Module then initiates the appropriate mode of timed climate control operation.

To set a timed climate program:

  1. Press the HOME MENU switch.
  2. Touch the Timed climate soft key. This soft key may be set on a personal shortcut or accessed via the Extra Features soft key. Select 7 day timer, or single event, then select the timer soft key. If the 7 day timer is selected, then select the day for which you want to set a program. Alternatively, select All week to select the same start time for every day.
  3. Touch the Timer 1 or Timer 2 soft key. The timers can be toggled between on and off using the power soft key.
  4. Touch the up or down arrows to set the start time. Hours and minutes are adjusted separately.
  5. Touch OK. The screen will display the activation time. If required, set the time for the other timer using the same process.
  6. Once set, the timer events can be turned on or off as required in the Timed climate screen by selecting the 7 day timer or the single event soft key.

NOTES:

  • Set times to be programmed according to the instructions on the touch screen.

  • Timed climate control will only operate once between engine starts. For example, a timed climate control request from the Fuel Fired Booster Heater (FFBH) remote control will not be performed if a programmed timed climate control event has already occurred.

Any programmed timed climate control cycle may be cancelled by touching the relevant power soft key on the timer set up menu or the Power soft key on the Timed climate information home menu.

Remote Control

When timed climate control is selected on or off with the Fuel Fired Booster Heater (FFBH) remote control. The request is received by the FFBH receiver via the right TV antenna and the TV antenna amplifier. The FFBH receiver relays the request as a hardwired signal to the Fuel Fired Booster Heater Control Module (FFBHCM). On receipt of the request, the FFBHCM sends the request to the HVAC Control Module on the Local Interconnect Network (LIN) bus. The HVAC then initiates the appropriate mode of timed climate control operation.

A ‘handshake’ signal is sent back from the FFBH receiver to the FFBH remote control to confirm a valid on or off request and activate the remote control Light Emitting Diode (LED) accordingly.

NOTE:

The ‘handshake’ signal only confirms the Fuel Fired Booster Heater (FFBH) remote control to the FFBH receiver communications was successful. Not that the request has been performed.

 

Timed Climate Control Operation

When the HVAC (HVAC Control Module) receives a timed climate control start request, its response depends on the ambient air temperature:

  • If the ambient temperature is 15°C (59°F) or more, the HVAC initiates parked ventilation and:

    • Operates the blower, depending on the ambient temperature, between 35% and 50% of the maximum speed.
    • Operates the distribution doors in the heater assembly to direct the air to the face vents.

  • If the ambient temperature is less than 16°C (61°F) and more than -25°C (-13°F), the HVAC initiates parked heating and:

    • Energizes the FFBH coolant changeover valve.
    • Sends a Local Interconnect Network (LIN) bus message to activate the Fuel Fired Booster Heater (FFBH).
    • Operates the blower, depending on the ambient temperature, between 35% and 50% of the maximum speed.
    • Operates the distribution doors in the heater assembly to direct the air to the footwell vents for approximately 30 seconds. Then to either only the windscreen, or to both the footwell vents and the windscreen, depending on the ambient air temperature.

  • If the ambient temperature is -25°C (-13°F) or below. The HVAC sends a LIN bus message to activate the FFBH, but leaves the FFBH coolant changeover valve de-energized and does not operate the blower or distribution doors. Heated coolant is circulated around the engine and heater core(s) to heat the engine and improve engine starting. Once the FFBH coolant temperature is above a suitable threshold the blower is switched on and passenger compartment heating commenced.

The FFBH will only activate in timed climate control if the following threshold conditions are met:

  • Pre-burn primary battery voltage check: ≥11.5V (at the FFBH terminals).
  • Pre-burn Engine Coolant Temperature (ECT) check: ≤15°C (internal FFBH measurement).
  • Pre-burn fuel level check: ≥7.5 liters (value stored in the FFBH at ignition off).

The fuel level value stored within the FFBH is only updated when the engine is running. When starting the FFBH in timed climate control with the engine off, the fuel level value used in the FFBH calculations will be that stored at the ignition off event. It is therefore possible for the FFBH to fail to operate in timed climate control if the engine was stopped with a low fuel level. If the fuel tank is subsequently refueled, the FFBH stored fuel level will still read low if the engine has not been started since refueling.

After 30 minutes, or if timed climate control is selected off with the touch screen or remote control, the HVAC discontinues timed climate control operation:

  • If parked ventilation is active, the HVAC:

    • Switches off the blower.
    • Returns the distribution doors to the previous settings.

  • If parked heating is active, the HVAC:

    • Sends a LIN bus message to de-activate the FFBH.
    • Switches off the blower.
    • Returns the distribution doors to the previous settings.
    • After 3 minutes, de-energizes the FFBH coolant changeover valve.

Transition from Timed Climate Control to Engine Running

Parked ventilation is automatically de-activated when the ignition is switched on.

Parked heating:

  • Is de-activated when the engine starts if the Engine Coolant Temperature (ECT) is equal to or more than the heater coolant temperature.
  • If the ECT is less than the heater coolant temperature, parked heating remains active until the ECT reaches the heater coolant temperature. The FFBH coolant changeover valve also remains closed until the ECT reaches the heater coolant temperature.

 

FUEL FIRED BOOSTER HEATER (NAS ONLY)

The Fuel Fired Booster Heater (FFBH) has only the FFBH coolant pump operational. The operation is control from the HVAC Control Module through the Fuel Fired Booster Heater Control Module (FFBHCM).

The FFBH coolant pump is operated to control the flow of engine coolant through the heater core in the climate control assembly.

ITEM DESCRIPTION
1 Rear Integrated Control Panel (RICP)

The auxiliary climate control system provides additional air distribution vents and separate temperature zones for the left and right areas of the rear seats. The auxiliary climate control system consists of:

  • An auxiliary climate control assembly.
  • A refrigerant circuit.
  • A heating circuit.
  • A distribution system.
  • The RICP (Rear Integrated Control Panel).

Operation of the auxiliary climate control system is controlled by the HVAC Control Module, the Rear Integrated Control Panel (RICP) and the Touch Screen (TS).For additional information, refer to:Control Components (412-01 Climate Control, Description and Operation).

Air from the passenger compartment is recirculated through the auxiliary climate control assembly, where the air is temperature regulated and then directed through the distribution system to vents in the headliner, the C pillar trim panels, and the carpet in front of the rear seats.

AUXILIARY CLIMATE CONTROL ASSEMBLY

E149518

 

















ITEM DESCRIPTION
1 Distribution motor
2 Blower
3 Isolation valve
4 Coolant pipes
5 Evaporator drain tube
6 Electrical connector for vehicle harness
7 Right temperature blend motor
8 Left temperature blend motor
9 Face distribution outlets (to headliner and C pillar vents)
10 Foot level distribution outlets (carpet vents under the seats)
11 Evaporator temperature sensor
12 Air conditioning pipe connector block
13 Blower control module

The auxiliary climate control assembly is installed on the left side of the luggage compartment, behind the rear quarter trim panel. A grille in the trim panel allows air to flow from the luggage compartment into the auxiliary climate control assembly.

The auxiliary climate control assembly consists of a casing, formed from a pair of plastic moldings, which contains:

  • An evaporator
  • A heater core
  • Temperature blend doors
  • A distribution door
  • A blower
  • A blower control module
  • An evaporator temperature sensor.

Refrigerant and coolant pipes from the engine compartment are connected to pipes from the evaporator and the heater core immediately below a seal plate in the rear left wheel arch. An evaporator drain tube, sealed with a foam rubber gasket, locates in the top of the left side member of the rear floor.

In the casing of the auxiliary climate control assembly, two parallel air steams flow from the blower through the evaporator and heater core to two pairs of distribution outlets. The left and right air streams supply the related rear zones of the passenger compartment. The front pair of distribution outlets supply the vents under the rear seats. The rear pair of distribution outlets supply the vents in the headliner and in the C pillar trim panels.

The left and right air streams each contain two temperature blend doors connected together with a link mechanism. Separate electric motors, installed on the rear of the casing, operate the temperature blend doors in each air stream to give independent temperature control for each rear climate zone.

The left and right air streams share a common distribution door installed below the distribution outlets. An electric motor, installed on the top of the casing, operates the distribution door.

A Local Interconnect Network (LIN) bus connects the distribution motor and the temperature blend motors in series with the HVAC. The motors are powered by feeds from the HVAC, and share a ground connection with the rear blower and rear blower control module.

The HVAC determines the positions of the distribution and temperature blend doors by using either their closed or open position as a datum and memorizing the steps that it drives the individual motors. Each time the HVAC is activated, it checks the memorized position of the motors against fixed values for the current distribution and temperature settings on the control panel. If there is an error, the HVAC calibrates the applicable motor, to re-establish the datums, by driving it fully closed or open before re-setting it to the nominal selected position. A calibration run can also be invoked using Land Rover approved diagnostic equipment.

BLOWER CONTROL MODULE

E149519

The blower consists of an open hub, centrifugal fan powered by an electric motor. Power for the blower is supplied from the rear blower relay in the Rear Junction Box (RJB) via the blower control module, which is installed in the left side of the auxiliary climate control assembly, immediately downstream of the blower. To control blower speed, the HVAC outputs a Pulse Width Modulation (PWM) signal to the blower control module to regulate the voltage of the blower power supply.

EVAPORATOR TEMPERATURE SENSOR

E149520

The evaporator temperature sensor is installed in the auxiliary climate control assembly on the downstream side of the evaporator. The evaporator temperature sensor is a Negative Temperature Coefficient (NTC) thermistor connected to the rear integrated control panel.

REFRIGERANT CIRCUIT

Low and high pressure pipes connect the front Air Conditioning (A/C) system to the auxiliary climate control assembly at a connector block in the left rear wheel arch, behind the wheel arch liner. On the auxiliary climate control assembly, pipes from the connector block are attached to an isolation valve on the evaporator.

AIR CONDITIONING PIPES

The A/C pipes consist of three sections of insulated pipe. The front and rear sections incorporate hoses at the ends that connect to the front A/C system and the auxiliary climate control assembly respectively. From the auxiliary climate control assembly, the A/C pipes are routed forward around the inboard side of the left rear wheel arch, then under the left edge of the floorpan to the rear of the left front wheel arch. The A/C pipes connect to the front climate control A/C system at a grommet in the wheel arch.

ISOLATION VALVE

E149521

The isolation valve is a combined solenoid operated shut-off valve and block-type thermostatic expansion valve attached to the inlet and outlet pipes of the evaporator. The HVAC controls the operation of the shut-off valve to isolate the auxiliary climate control assembly from the front A/C system.

HEATER CIRCUIT

Supply and return coolant pipes connect the engine cooling system to the heater core pipes of the auxiliary climate control assembly in the left rear wheel arch, behind the wheel arch liner.

The coolant pipes consist of sections of insulated rigid pipes connected together with flexible hose joints. Quick release fittings connect the coolant pipes to the engine cooling system.

From the auxiliary climate control assembly, the coolant pipes are routed along the rear cross member and then forward under the right edge of the floorpan to the chassis longitudinal at the rear of the right front wheel arch liner.

DISTRIBUTION SYSTEM

The distribution system consists of a network of air ducts that supply air from the distribution outlets of the auxiliary climate control assembly to the vents installed in:

  • The headliner, above each rear door
  • The left and right C pillar trim panel
  • The carpet, below the left and right rear seats.

The vents in the headliner, and in the C pillar trim panel are adjustable, those in the carpet are fixed.

Four duct air temperature sensors are installed in the air ducts. Two sensors are installed in the left and right upper air ducts, to measure the air temperature of the headliner, and C pillar trim panel outlets. Two sensors are fitted in the lower air ducts, to measure the air temperature of the outlets below the seats. The sensors are NTC thermistors, which are connected to the RICP. The HVAC uses the data from the sensors in output temperature calculations for the related ducts.

REAR INTEGRATED CONTROL PANEL

E189845

 










ITEM DESCRIPTION
1 Foot distribution switch
2 Automatic mode switch
3 Face distribution switch
4 Right temperature switch
5 Blower and on/off switch
6 Left temperature switch

The RICP is installed in the rear of the floor console. The control panel contains rotary and push button switches for controlling the temperature, volume and distribution of air ro the rear seats. Each push switch contains an amber status Light Emitting Diode (LED). Display screens are integrated into the center of the rotary switches to display the selected temperature and blower speed as appropriate.

Additional push switches on the RICP are provided for control of seat heating/climate control seats.For additional information, refer to:Seats (501-10 Seating, Description and Operation).

The RICP has a permanent battery power feed from the Passenger Junction Box (PJB), and is connected to the High Speed (HS) Controller Area Network (CAN) Comfort bus. The RICP converts selections on the climate control switches into HS CAN Comfort messages, and transmits them to the HVAC. The RICP also receives inputs from the auxiliary climate system evaporator temperature sensor and four duct air temperature sensors. These inputs are also converted into HS CAN Comfort messages and transmitted to the HVAC Control Module.

For the auxiliary climate control system to operate, the engine must be running and automatic mode selected on the RICP or the Rear climate menu of the TS. The HVAC then illuminates the LED in the RICP AUTO switch, energizes the isolation valve and the rear blower, and operates the temperature blend and distribution motors to maintain the temperatures selected on the RICP. If the main climate control system is not already operating, the HVAC also activates the A/C compressor and operates the main climate control system in automatic mode.

Once the auxiliary climate control system is operating, the blower, distribution and temperature can be adjusted as required on the RICP or the Rear Climate menu of the touch screen. More than one distribution setting at a time may be selected to achieve the required air distribution.

The auxiliary climate control system can be selected off on the RICP, using the AUTO switch, or on the Rear Climate menu of the TS. The Rear Climate menu can also be used to lock the RICP to prevent operation of the auxiliary climate control system from the rear seats.
