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.

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.
