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

memory positions to be stored and 'set' button with integral LED (light emitting diode). The seat, door mirror and steering
column motors have position sensors which provide feedback to driver's seat module.

Once the driver's seat, steering column and exterior mirrors have been adjusted, the vehicle is able to memorize these
settings for future use by using the following procedure:
Push the memory 'SET' button, the LED in the switch will illuminate Press the memory button 1 or 2 to memorize the current settings. The LED will extinguish, and a chime will sound to confirm that the settings have been memorized. If the ignition is on, power mode 6, the message center will display a
confirmation message.
The positions can be recalled by pressing the applicable button 1 or 2.
Stall Detection

Seat, steering column and mirror motors are deemed to have stalled if there is no change in the inputs that are received from
the corresponding feedback sensors for 200 ms (seat).

If a stall condition is detected then the drive to that motor is cancelled for the remainder of that memory operation (memory
recall) or until the switch is re-selected (manual movement).

If the motor movement has stopped due to loss of sensor feedback, either stall or sensor failure, then that motor may be
activated again, to move past the stall position, by re-selecting the appropriate switch and pressing for longer than 2 seconds.
This allows control of the motor to be maintained if sensor feedback is lost.

Upon re-selection of movement, if sensor pulses are detected then the motor will continue to be driven until the switch is
released or another stall condition is detected. If sensor feedback is not detected then the motor is only driven for 0.5 second
and then stops until the switch is released and then pressed again, when a further 0.5 second of activation is permitted, and
so on, this is known as inch mode.

For all seat motor manual movements, whenever a motor is driven and a stall occurs, the memory control module records the
position at which the stall occurred. If movement occurs beyond a stall position, then that position is erased from the control
modules memory. This will always allow movement past a previously recorded stall position once movement has been
registered beyond that position. This is the case for both manual and memory movement.
Initialization

When a replacement driver's seat module is fitted, it should be calibrated a Jaguar approved diagnostic system so that the
module can learn the seats absolute position.
Battery Monitor

If the battery voltage drops below 10.5 Volts, then the driver's seat module ignores all requests for a memory recall until the
battery voltage has reached 11.5 Volts. This will conserve as much power in the vehicle battery as possible to enable engine
cranking.

REAR SEATS - DESCRIPTION

The rear seat features a single piece cushion and a 60/40 split squab. Two latches are secured to the rear bulkhead by a pair
of M8 bolts to retain the seat squabs in the upright position. The latches can be released to fold down the individual cushions
by pulling a cable release located below the rear window parcel shelf in the luggage compartment.
ISOFIX fastening points are attached to the vehicle floor to provide secure fastening for compatible child seats.

A centrally mounted center arm rest can be folded down from the 60% squab. The arm rest contains two drinks holders.
