Principles of Operation

For a detailed description of the speed control system, refer to the relevant Description and Operation sections in the
workshop manual.

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.

2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.

4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively, check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
Speed Control Sensor Adjustment (vehicles with adaptive system installed)

An incorrectly aligned speed control sensor can cause incorrect system operation. Before starting any repair work on the speed
control system, on vehicles with the adaptive system installed, check speed control sensor for correct vertical alignment, and
carry out speed control sensor alignment procedure using manufacturer approved diagnostic system.

System Operation
Operation of the heating and ventilation system is controlled by the ATC module. Refer to: Control Components (412-01 Climate Control, Description and Operation).
The system can be operated in automatic or manual mode, with temperature settings selected using the switches on the
integrated control panel.

When the engine is running, coolant is constantly circulated through the heater core by the engine coolant pump and the
auxiliary coolant pump. Where fitted, the auxiliary coolant pump is energized by the CJB on receipt of medium speed CAN bus signals from the ATC module. The CJB broadcasts auxiliary coolant pump status over the medium speed CAN bus for use by other vehicle systems.

The blower is supplied with power by the blower relay on the RJB and connected to ground via the blower control module. The blower control module regulates the voltage across the blower motor to control blower speed. The voltage set by the blower
control module is controlled by a PWM (pulse width modulation) signal from the ATC module. The ATC module uses a feedback signal from the blower control module to monitor blower speed.
Refer to: Control Components (412-01 Climate Control, Description and Operation).


Heater Assembly Component Description

The heater assembly controls the temperature and flow of air supplied to the air distribution ducts. The heater assembly is
mounted on the vehicle centerline, between the instrument panel and the engine bulkhead.

The heater assembly consists of a casing that contains an A/C (air conditioning) evaporator, a heater core, two air distribution
control doors and two temperature blend control doors. On 2.7L diesel vehicles, the heater assembly also contains an electric
booster heater.
Refer to: Electric Booster Heater (412-02 Auxiliary Climate Control, Description and Operation).
Mounted on the heater casing are four stepper motors. Each of the stepper motors is connected to either an air distribution
control door or a temperature blend control door.
The A/C evaporator is part of the A/C system. Refer to: Air Conditioning (412-01 Climate Control, Description and Operation).
The heater core provides the heat source to warm the air supplied to the passenger compartment. The heater core is an
aluminum two pass, fin and tube heat exchanger, and is installed across the width of the heater housing. Two aluminum tubes
attached to the heater core extend through the engine bulkhead and connect to the engine cooling system. For additional
information, refer to:
Engine Cooling (303-03A, Description and Operation),
Engine Cooling (303-03B Engine Cooling - V6 3.0L Petrol, Description and Operation), Engine Cooling (303-03C, Description and Operation).

Air Inlet Duct

The air inlet duct connects the fresh air inlet in the engine bulkhead to the heater assembly. The air inlet duct is installed
behind the instrument panel on the passenger side.

The air inlet duct consists of a casing that contains a pollen filter, an air inlet door, a blower and a blower control module. A
recirculation air inlet is incorporated into the casing. A servo motor is mounted on the casing and connected to the air inlet
door, to allow selection between fresh and recirculated air.
Refer to: Control Components (412-01 Climate Control, Description and Operation). The pollen filter is part of the air distribution and filtering system.
Refer to: Air Distribution and Filtering (412-01 Climate Control, Description and Operation).
The blower regulates the volume of air flowing through the air inlet duct to the heater assembly. The blower consists of an
open hub, centrifugal fan and an electric motor.
The blower control module regulates the power supply to the blower motor. The blower control module is installed in the air

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.
