Description and Operation

Overview
The exterior mirrors incorporate the following:
Blind spot monitoring indicator
Auto dimming function
Turn signal indicators
Approach lamps
Exterior temperature sensor
Heated mirror function
Reverse dipping function Published: 11-May-2011
Movement of the door mirrors is controlled from a switch pack located on the drivers door. The switch pack contains 2
non-latching mirror select buttons labeled 'L' and 'R' and a 4-way mirror movement switch. Door mirror movement commands
are transmitted to the driver's door module over the LIN (local interconnect network) bus. The drivers door module transmits
any mirror movement commands to the passenger door module over the medium speed CAN (controller area network) bus.

Movement of the door mirrors is carried out by the respective door module. The door modules provide supply and ground paths
to the mirror motors and monitor mirror position via potentiometers located in the mirror housings.

Both exterior door mirrors and the interior mirror feature an auto dimming function. The interior rear view mirror contains one
forward and one reward facing light sensor. The light sensors control the auto dimming feature of the interior mirror to reduce
glare from the headlights of following vehicles.

When auto-dimming of the interior mirror is required, a supply is provided by the interior mirror to both door mirrors to initiate
the door mirror auto-dimming sequence.

Blind spot monitoring function alerts the driver to a vehicle located in the vehicle blind spot. A warning indicator is located in
each exterior mirror towards the outer edge.

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.

Exterior rear view mirror glass
Fuse(s)
Relay(s)
Wiring Harness
Electrical connector(s)
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, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC Index


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures 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 additional 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 an up-to-date 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.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


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.


When carrying out repair/diagnosis of the system, on removal of the front or rear bumper inspect the sensor connectors
to ensure they were correctly latched and check fly leads for signs of chaffing or trapped wires.
