General System Operation

Operation of the electric booster heater is controlled by the ATC module, which communicates with the micro-controller in the booster heater using the LIN bus. The temperature requested by the ATC module is based on:
The ambient air temperature.
The engine coolant temperature.
The temperatures selected on the integrated control panel.

The blower must be running for the electric booster heater to operate.
If electrical load management is in force, electric booster heater performance is reduced. For additional information, refer to:
Electronic Engine Controls (303-14A, Description and Operation),
Electronic Engine Controls (303-14B Electronic Engine Controls - V6 3.0L Petrol, Description and Operation), Electronic Engine Controls (303-14C, Description and Operation).



Electric Booster Heater Component Description



The electric booster heater is installed in the heater assembly, on the downstream side of the heater core. It consists of
ceramic coated thermistor elements, rated at 1.25 kW, and a micro-controller. Electrical power for the booster heater is
supplied by the BJB via a 150 A megafuse installed under the RH front seat.

4. NOTE: Clamp the coolant hose to minimize coolant














5. Lower the vehicle.

6. Remove the coolant expansion tank pressure cap.

7. Fill the cooling system up to the MAX mark on the coolant expansion
tank using a fifty percent mixture of Jaguar Premium Cooling System
Fluid or equivalent, meeting Jaguar specification WSS M97B44-D and
fifty percent water.

8. Install the coolant expansion tank pressure cap.

9. Start and run the engine.

10. Set the heating system to MAX heat, the blower motor to MAX speed
and the air distribution to the instrument panel registers.


11. CAUTION: Observe the engine temperature gauge. If the engine
starts to over-heat switch off immediately and allow to cool. Failure to
follow this instruction may cause damage to the vehicle

Allow the engine to run until hot air is emitted from the instrument
panel registers, while observing the engine temperature gauge.

12. Switch the engine off.

13. Allow the engine to cool.

gage, odometer, trip distance and trip computer readouts. The trip distance and trip computer information is derived from
information supplied on the high speed CAN bus to the instrument cluster from the ABS module and the ECM.
The area above the message center displays the transmission gear position information and speed control related information.
The transmission information is supplied on the high speed CAN bus from the TCM (transmission control module).

NOTE: There is no engine coolant temperature gage displayed. If the engine coolant temperature increases to above a
predetermined threshold, a warning message is displayed in the message center. The message is sent from the ECM in a high speed CAN message to the instrument cluster.
TRANSMISSION GEAR SELECTION POSITION

The gear position display shows JaguarDrive selector position or selected gear when using the Jaguar Sequential Shift. The gear
selector module transmits a CAN message to the instrument cluster for gear selector lever position. The module also outputs a 'not in park' signal to the instrument cluster. The TCM transmits a high speed CAN message to the instrument cluster with data containing the selected gear when in Jaguar Sequential Shift mode.
