NOTES:


If a module or component is suspect, and the vehicle remains under the Manufacturers warranty, refer to the Warranty
Policy and Procedure manual (section B1.2), or determine if any prior approval programme is in operation, prior to the
installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by
the manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places and
with a current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.

control switch on the integrated control panel or the + and - soft buttons on the touch screen display (TSD). The ATC module also adjusts blower speed to compensate for the ram effect on inlet air produced by forward movement of the vehicle. As
vehicle speed and ram effect increases, blower motor speed is reduced, and vice versa.

Air Distribution Control

Two air distribution doors are used to direct air into the passenger compartment. The doors are operated by stepper motors,
which are controlled by the ATC module using LIN bus messages.
When the A/C system is in automatic mode, the ATC module automatically controls air distribution into the passenger compartment in line with its 'comfort' algorithm. Automatic control is overridden if any of the TSD air distribution soft buttons
are selected. Air distribution in the passenger compartment will remain as selected until the 'Auto' switch is pressed or a
different manual selection is made.

A/C Compressor Control

When A/C is selected the ATC module maintains the evaporator at an operating temperature that varies with the passenger compartment cooling requirements. If the requirement for cooled air decreases, the ATC module raises the evaporator operating temperature by reducing the flow of refrigerant provided by the A/C compressor. The ATC module closely controls the rate of temperature increase to avoid introducing moisture into the passenger compartment.

If the requirement for cooled air increases, the ATC module lowers the evaporator operating temperature by increasing the flow of refrigerant provided by the A/C compressor.
When A/C is off, the compressor current signal supplied by the ATC module holds the A/C compressor solenoid valve in the minimum flow position, effectively switching off the A/C function.
The ATC module incorporates limits for the operating pressure of the refrigerant system. If the system approaches the high pressure limit, the compressor current signal is progressively reduced until the system pressure decreases. If the system falls
below the low pressure limit, the compressor current signal is held at its lowest setting so that the A/C compressor is maintained at its minimum stroke. This avoids depletion of the lubricant from the A/C compressor.
A/C Compressor Torque

The ATC module transmits refrigerant pressure and A/C compressor current values to the ECM (engine control module) over the medium speed then high speed CAN bus, using the CJB as a gateway. The ECM uses these values to calculate the torque being used to drive the A/C compressor. The ECM compares the calculated value with its allowable value and if necessary forces the ATC module to inhibit the A/C compressor by transmitting the 'ACClutchInhibit' CAN message. This forces the ATC module to reduce the drive current to the A/C compressor solenoid valve, which reduces refrigerant flow. This in turn reduces the torque required to drive the A/C compressor.
By reducing the maximum A/C compressor torque, the ECM is able to reduce the load on the engine when it needs to maintain vehicle performance or cooling system integrity.

Cooling Fan Control

The ATC module determines the amount of condenser cooling required from the refrigerant pressure sensor, since there is a direct relationship between the temperature and pressure of the refrigerant. The cooling requirement is broadcast to the ECM on the medium speed CAN bus. The ECM then controls the temperature of the condenser using the cooling fan.
Programmed Defrost

The programmed defrost DEF switch is located on the integrated control panel. When the switch is pressed, the ATC module instigates the programmed defrost function. When selected, the ATC module configures the system as follows:
Automatic mode off.
A/C on. Selected temperature unchanged.
Air inlet set to fresh air.
Air distribution set to windshield.
Blower speed set to level 6.
Windshield heater (where fitted) and rear window heater on.
The programmed defrost function can be cancelled by one of the following:
Selecting any air distribution switch on the TSD.
Pressing the AUTO switch on the integrated control panel.
A second press of the DEF button.
Switching the ignition OFF.
The blower speed can be adjusted without terminating the programmed defrost function.

Rear Window Heater

Rear window heater operation is only enabled when the engine is running. The ATC module controls operation of the rear window heater using a relay in the RJB. When rear window heater operation is required, the ATC module broadcasts a message to the RJB on the medium speed CAN bus. On receipt of the message, the RJB energizes the relay by providing a ground path for the relay coil. This allows a battery feed to flow across the relay to power the rear window heater element.
