Anti-Theft - Active - Anti-Theft - Active - Overview
Description and Operation

Overview Published: 11-May-2011

The active anti-theft system is available with three different levels of vehicle protection depending on market specification:

Hinged panel sensing
Hinged panel and intrusion sensing
Hinged panel, intrusion and inclination sensing.

The CJB (central junction box) automatically arms and disarms the active anti-theft system when it functions the central
locking system.
Refer to: Handles, Locks, Latches and Entry Systems (501-14 Handles, Locks, Latches and Entry Systems, Description and Operation).
Depending on market specification two modes of protection are used: perimeter mode and volumetric mode.

Perimeter mode
Perimeter mode, monitors the security of the hinged panels, which include:
all doors,
luggage compartment lid, and
engine compartment lid.

When perimeter mode is active, the CJB monitors the panel ajar switches in the latch mechanisms of the hinged panels.
Volumetric mode

In volumetric mode the CJB monitors the interior of the vehicle for movement using an ultrasonic sound wave sensor.

If the battery backed sounder incorporates an inclination sensor the vehicle will also be monitored for unauthorised tilting; for
example towing or jacking.

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

For a detailed description of the seats and seat operation, refer to the relevant Description and Operation section in the
workshop manual. REFER to: (501-10 Seating)

Seats (Description and Operation), Seats (Description and Operation), Seats (Description and Operation).
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.


NOTE: Prior to carrying out any diagnosis, ensure the vehicle battery is in a good serviceable condition, refer to the
battery care manual.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection
Mechanical Electrical
Security, condition and correct installation of seat components and fixings
Fuses
Harnesses for damage/corrosion
Electrical connectors
Damaged/corroded pins
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 concern and refer to the Symptom Chart, alternatively, check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

5. Check DDW for open campaigns. Refer to the corresponding bulletins and SSM's which may be valid for the specific
customer complaint and carry out the recommendations as needed.
