bus. Temperature control for the heater element is provided by the steering wheel heater control module which receives a
temperature feedback signal from a NTC (negative temperature coefficient) thermistor located within the steering wheel.



ATC Module Component Description



The ATC module is mounted on the outboard end of the air inlet duct, behind the front passenger side of the instrument panel. The ATC module processes inputs from the TSD, the switches on the integrated control panel and the system sensors. In response to these inputs, the ATC module outputs control signals to the A/C system and the heating and ventilation system.
Two electrical connectors provide the interface between the ATC module and the vehicle wiring. The ATC module uses hardwired inputs from the system sensors, the LIN bus to communicate with the stepper motors and the medium speed CAN bus to communicate with other control modules on the vehicle.

A/C Compressor Solenoid Valve

The A/C compressor solenoid valve is integral with the A/C compressor. Operation of the solenoid valve is controlled by the ATC module using a hardwired drive current of differing values. By controlling the flow of refrigerant through the compressor, the
solenoid valve can control the A/C system pressure and the evaporator operating temperature.
Refrigerant Pressure Sensor



The refrigerant pressure sensor provides the ATC module with a pressure input from the high pressure side of the refrigerant system. The refrigerant pressure sensor is located in the refrigerant line between the condenser and the thermostatic
expansion valve.

The ATC module supplies a 5 V reference voltage to the refrigerant pressure sensor and receives a return signal voltage, between 0 V and 5 V, related to system pressure.

The ATC module uses the signal from the pressure sensor to protect the refrigerant system from extremes of pressure. The ATC module transmits the A/C pressure, along with the compressor drive current value, to the instrument cluster on the medium speed CAN bus. These signals are broadcast to the ECM on the high speed CAN bus to allow it to calculate the torque being applied to the engine by the compressor. www.JagDocs.com

1 LH door mirror 2 Ambient air temperature sensor The ambient air temperature sensor is a NTC thermistor that provides the ATC module with an input of external air temperature. The sensor is hard wired to the ECM and its signal is transmitted to the instrument cluster on the high speed CAN bus. The instrument cluster acts as a gateway and transmits the ambient air temperature signal to the ATC module on the medium speed CAN bus. The sensor is installed in the LH door mirror, and is accessed by removing the mirror glass, cap and actuator.

Sunload Sensor



The sunload sensor consists of two photoelectric cells that provide the ATC module with inputs of light intensity; one as sensed coming from the left of the vehicle and one as sensed coming from the right. The inputs are a measure of the solar
heating effect on vehicle occupants, and are used by the ATC module to adjust blower speed, temperature and distribution to improve comfort.

The sensor is installed in the speaker grill on the upper surface of the instrument panel. Power for the sensor is provided by a
5 V feed from the instrument cluster.
The sensor also contains the active anti-theft alarm indicator.

8 LH door module 9 Exterior mirror control switches
System Operation
The rear view mirrors comprise an interior mirror mounted to the windshield, and an exterior mirror mounted on each front door
cheater. The types of mirrors and associated operating functions installed depend on the specification and trim level of the
vehicle.

Interior Mirrors

The interior rear view mirror is provided as a manual dimming or an electrically operated automatic dimming type.

The manual dimming mirror comprises a prismatic glass housed within a surrounding case that is attached with a ball joint
connector to the mirror stem. Manual dimming of the mirror is achieved using the lever mounted on the underside of the mirror
body. Operating the lever will tilt the mirror head from the 'day' position to the 'night' position.

The automatic dimming mirror comprises an electro-chromatic glass housed within a surrounding case that is attached with a
ball joint connector to the mirror stem. The mirror stem incorporates an 8-pin electrical connector that is connected to the roof
panel wiring harness. The wiring harness provides hardwired and a LIN connection to the CJB.
Light sensors are mounted on the front and rear of the mirror surround case. The sensors control the automatic dimming
feature to reduce glare from the headlights of following vehicles.

The automatic dimming function is permanently active when the ignition is in power mode 4 (Accessory) and power mode 6
(Ignition). The forward facing light sensor monitors the ambient light level at the front of the vehicle; the rearward facing light
sensor monitors the light level coming from the rear of the vehicle. When light from the rear of the vehicle exceeds the
ambient light level from the front of the vehicle, the automatic dimming circuit darkens the interior mirror surface.

Automatic dimming is inhibited when reverse gear is selected to provide the driver with maximum vision. On vehicles with
automatic transmission, the reverse gear signal is provided by the TCM (transmission control module) via the high speed CAN bus to the CJB. The CJB then provides a power feed to the mirror. On vehicles with manual transmission, the reverse gear signal is provided by a transmission switch that is hardwired to the CJB.
Exterior Mirrors

Electrically operated and heated exterior mirrors are installed as standard. Depending on the specification and trim level of the
vehicle, the following options are available:

Power fold (switch pack operated feature) and auto fold (remote handset operated feature)
Memory recall
Reverse gear mirror dip
Mirror heating
Exterior mirror lamps.

The power fold/auto fold feature is available only when power fold mirrors are installed to the vehicle.

The mirrors can be configured to automatically fold when the vehicle is locked and unfold when unlocked. This feature can be
enabled or disabled via the Vehicle settings area of the touch screen:

Select 'Settings' from the touch screen Home menu.
Select ' Security/Vehicle'
Select 'Windows/Mirrors'
Select Power Fold 'On' or 'Off' as appropriate.

The pasenger side mirror can be configured to automatically dip when reverse gear is selected. This feature can be enabled or
disabled via the Vehicle settings area of the touch screen:

Select 'Settings' from the touch screen Home menu.
Select ' Security/Vehicle'
Select 'Windows/Mirrors'
Select Reverse dip 'On' or 'Off' as appropriate.

The LH door mirror incorporates an ambient air temperature sensor that is hardwired to the ECM (engine control module). The ECM is connected to the CJB and other control modules via the high speed CAN bus. The sensor provides information to the ECM that is then transmitted on the medium speed CAN bus for use by other control modules. On vehicles installed with a high-line instrument cluster, the CJB transmits the temperature signal to the instrument cluster that provides a display of the ambient temperature to the driver.
The exterior mirror lamps are controlled by the interior lighting function.

The door mirrors are controlled using a switch pack located on the driver's door. The switch pack contains 2 non-latching mirror
select switches labeled 'L' and 'R' and a 4-way directional joystick. The switch pack is connected to the driver door control
module via the LIN bus. The driver and front passenger door control modules are connected via the medium speed CAN bus. A hardwired connection between each door control module and the corresponding door mirror, provides the supply and ground
paths for the mirror motors.
Each exterior door mirror incorporates 2 motors to control horizontal (left/right) and vertical (up/down) adjustments. www.JagDocs.com

On vehicles installed with a driver's power operated memory seat and memory exterior mirrors, a potentiometer is incorporated
within each mirror motor and is used to provide information regarding the actual motor positions. The current position and
memory positions of each door mirror motor are maintained and stored within the corresponding door control module.

The memory exterior mirror positions are also monitored and stored within door control module memory when the reverse gear
mirror dip function is used.

When reverse gear is selected, the door control module stores the current mirror positions and will then dip the passenger
mirror glass to a default dip position. While reverse gear is selected it is possible to store a preferred dipped mirror position by
adjusting the driver/passenger mirror glass to the desired position via the mirror switch pack. When the desired position is
achieved using the switch, the new dip positions will be automatically stored by the door control module when reverse gear is
de-selected. Therefore when reverse gear is re-selected, the dip position recalled by the door control module will be the new
reverse gear mirror dip stored position. When reverse gear is deselected the mirror glass will automatically move to the previous
stored position prior to reverse gear selection.

If the driver selects a memory recall function using the memory seat switch pack, the driver's memory seat and exterior
memory mirrors are moved to a stored memory position.

Exterior mirrors with the power fold/auto fold feature incorporate a motor located in the hinge of each exterior mirror arm.
Operation of the power fold feature is achieved using the exterior mirror switch pack. Operation of the auto fold feature is
achieved using the remote handset.
The power fold function is active when the ignition is in power mode 6 (Ignition).

Both exterior mirrors will power fold when the mirror switch pack 'L' and 'R' switches are pressed together. Pressing the
switches again will unfold the mirrors.

When the instrument cluster is configured for the auto fold feature, the mirrors will fold in when the remote handset lock
button is pressed. The mirrors will unfold when the vehicle is unlocked using the remote handset unlock button.


NOTE: If the mirrors are folded in using the mirror switch pack (power fold) and the vehicle is then locked, subsequent
unlocking of the vehicle will not unfold the mirrors.

When the remote handset unlock button is operated, the CJB recognizes the remote handset for that vehicle and acknowledges the request. The door control modules are connected directly to the AJB (auxiliary junction box) for power supply to the
exterior mirror folding motors.

When the vehicle is locked the door control modules reverse the polarity of the mirror fold motor, power and ground
connections to operate the mirrors in the opposite direction.

Exterior mirror heating is provided with heater elements bonded to the back of the mirror glass. Power supply for the mirror
heating elements is provided by the corresponding driver or passenger door control module via the RJB. The door control modules receive a power supply from the RJB, and are both connected on the medium speed CAN bus to the ATC (automatic temperature control) module. A ground terminal from each door control module completes the circuit. The ATC module automatically controls the mirror heating function whenever the ignition is in power mode 4 (Accessory) and power mode 6
(Ignition).

Operation of the exterior mirror heaters is fully automatic and not controllable by the driver. Exterior mirror heater operation is
determined by ambient air temperature and windshield wiper status. When ambient air temperature reaches a pre-determined
level, the ATC module broadcasts an exterior mirror heating request to the door modules over the medium speed CAN bus. On receipt of this message, the door modules provide feed and ground connections to both exterior mirror heater elements.

The mirror heating is controlled in two phases, the initial heating phase and a second PWM (pulse width modulation) controlled
phase. In the first phase the heater elements in the mirrors are permanently powered for a pre-determined length of time. This
length of time varies with the ambient temperature. During the second PWM phase, the heater elements are turned on and off every 30 seconds. The amount of time the exterior mirror heaters are operational increases if the windshield wipers are
switched on. This ensures the mirrors remain mist free in damp and wet conditions, where there is an increased risk of misting.
