Door Modules Component Description

The door modules provide the interface between the door latch-motors, the door latch-switches and the CJB. The door modules
provide door switch status information and enable the door latch-motors on request from the CJB or the keyless vehicle
module.

Keyless Vehicle Module

The keyless vehicle module interfaces with the Central locking, Radio Frequency (RF) receiver and collects RF signal information
which is transmitted from the Smart Key. This information is translated into commands which are passed on the medium speed
CAN bus to the:

CJB,
RJB,
door modules, and
instrument cluster.
The keyless vehicle module also monitors:
2 interior antennae,
1 luggage compartment antenna,
a rear bumper antenna, and
4 door handle antennae if the passive entry system is fitted.

On vehicles with passive entry, the additional fast latch motors are controlled via the keyless vehicle module and the locking
status is passed to the CJB on the medium speed CAN bus.

Instrument Cluster

The instrument cluster controls the alarm indicator, and in conjunction with the ECM (engine control module), the engine
immobilization. The ECM controls the engine crank and fuel functions and the instrument cluster processes the valid
transponder information.

Alarm Indicator

The alarm indicator is a LED (light emitting diode) located in the body of the sunload/light sensor. When the ignition is off the
indicator gives a visual indication of the active anti-theft system to show if the alarm system is active or not active. Operation
of the alarm indicator is controlled by the instrument cluster which varies the flash rate of the LED to indicate the system
status of the alarm and the immobilization systems.

When the ignition is on, the indicator provides a visual indication of the status of the passive anti-theft (engine
immobilization) system. If the immobilization system is operating correctly, the LED will be illuminated for 3 seconds at
ignition on and then extinguish. If a fault exists in the immobilization system, the LED will be either permanently illuminated
or flashing for 60 seconds. This indicates that a fault exists and fault code has been recorded. After the 60 second period the
LED will flash at different frequencies which indicate the nature of the fault.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
Passive Anti-Theft Horn

The passive anti-theft horn is hardwired to the CJB which activates the horn when the alarm is triggered.

Battery Backed Sounder

Operation of the battery backed sounder is controlled by the CJB on the LIN bus. The sounder is also connected with a
permanent battery supply via the CJB. An integral, rechargeable battery powers the sounder if the battery power supply from
the CJB is interrupted.

Dependant on vehicle, a incitation sensor is incorporated into the battery backed sounder, to monitor vehicle attitude, see
Inclination Sensor.

Inclination Sensor

The CJB monitors the inclination sensor and will activate the alarm system if the vehicle is being raised.

Intrusion Detection Module

The intrusion detection module comprises an ultrasonic sound wave sensor which monitors the vehicle's interior.

The intrusion detection module is activated with volumetric mode which in turn is enabled when the vehicle is double locked.
The vehicle can be locked and alarmed with the module de-activated if a pet is to be left in the vehicle for example by single-

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
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 electrical 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.

System Operation

The passive start function prevents the vehicle from being started by unauthorized persons. It does this by immobilizing the
ignition, fuel and engine crank functions. The system is automatic and requires no input from the driver.

At the request of the CJB, the keyless vehicle module prompts each of the Low Frequency (LF) antennae to output a signal. When the Smart Key is in the vehicle cabin, it detects the LF signals and responds with a Radio Frequency (RF)
data-identification signal back to the keyless vehicle module via the RF receiver.

If the data received matches that stored in the keyless vehicle module it continues the passive start process by
communicating a 'Smart Key valid’ signal to the CJB via the medium speed CAN (controller area network) bus.

Once the CJB receives the authorization and confirms a response with an internal calculation, it passes the result to the
instrument cluster on the medium speed CAN bus.
Before the instrument cluster sends a mobilization signal to the ECMit will exchange encrypted data with: The electric steering lock mechanism to authorize unlocking the steering column.
The RJB to authorize fuel pump operation. Once the RJB receives the authorization and confirms the response with an internal calculation, it will enable the FPDM (fuel pump driver module).
The CJB to authorize the ignition status. If the drive selector is in the park position and the driver presses the brake
pedal and simultaneously presses the start/stop switch, the CJB interprets this as an engine crank request. Before the
engine crank request is allowed, the CJB compares a brake pressure signal received from the ABS module. The brake pressure signal is compared to an internally stored threshold value within the CJB. If the signal is greater than the
stored threshold value, a crank request signal is sent to the ECM on the high speed CAN bus.

Once these factors have been confirmed, and the vehicle is in 'Park', the engine can be started by pressing the brake pedal and
the Stop/Start button simultaneously.
NOTES:


If the keyless vehicle module fails to locate the Smart Key, the message 'SMART KEY NOT FOUND PLEASE INSERT IN
SLOT' will appear in the instrument cluster message center. When inserted the start control module will read the transponder
within the Smart Key. If the transponder identification is valid, authorization will be transmitted to the instrument cluster on
the LIN (local interconnect network) bus.


When the vehicle is delivered from the factory the passive start function is inhibited. In this condition the vehicle can
only be started by placing the Smart Key in the start control module. The system should be switched on during the Pre-Delivery
Inspection (PDI) using the Jaguar approved diagnostic system. For additional information, refer to the PDI Manual.

To ensure optimum long term reliability of the smart key the battery must be replaced with a brand new, unused battery. If a
used battery is installed the "SMART KEY BATTERY LOW" message may not be cleared. To avoid contamination of the contacts
the battery should be removed from its packaging and installed into the smart key while wearing gloves. To confirm that the
replacement battery is working correctly press the unlock button twice while holding the smart key outside the vehicle, then
enter the vehicle with the smart key, press the start button and confirm that the "SMART KEY BATTERY LOW" message is not
displayed.



Start Control Module Component Description

The start control module is used if the keyless vehicle module is unable to authorise the Smart Key.

If the keyless vehicle module is unable to identify the Smart Key, for example if the Smart Key battery voltage is low or there
is local RF interference, the transponder within the Smart Key can be read in the conventional manner. The driver will be
alerted to this by a chime and a message in the instrument cluster message center 'SMART KEY NOT FOUND PLEASE INSERT IN
SLOT'.

Once inserted the start control module will read the transponder within the Smart Key. If the transponder identification is
valid, authorization will be transmitted to the instrument cluster on the LIN bus.


NOTE: Inserting the Smart Key into the start control module will not charge the Smart Key battery. The battery is
non-chargeable and must be replaced if defective.

A message 'REMOVE SMART KEY' will be displayed if the Smart Key is still in the start control module and the driver's door is
opened.

Low Frequency Antenna

Three Low Frequency (LF) antennae for the passive start system are positioned in specific locations in the vehicle; refer to
Component Location graphic.


NOTE: On vehicles with the passive entry system, five additional antennae are used; one integrated into the rear bumper
and one in each door handle assembly. These are only used by the passive entry system and have no function in the passive
start system.

The keyless vehicle module transmits an LF signal via the antennae which is received by the Smart Key. The Smart Key then
responds by transmitting a Radio Frequency (RF) signal which is received by the RF receiver and passed to the keyless vehicle
module for authorization.

Keyless Vehicle Module

The keyless vehicle module controls signal transmissions to and from the Smart Key and provides authorization to allow the
vehicle to be started. The module has a medium speed CAN connection to the CJB for authorizing vehicle starting.

Radio Frequency Receiver

The Radio Frequency (RF) receiver transmission is received from the Smart Key to enable key identification.

Inspection and Verification

Anti-theft - Passive

The best method to confirm the correct operation of the Passive Anti-Theft System (PATS) is to check the LED (located in the
center of the instrument panel). The LED should illuminate solid for 3 seconds, when the ignition status is set to ON, and then
extinguish. This validates all PATS functions (i.e. the key transponder matches a stored key code, the challenge/response
sequence between the respective modules was successful resulting in the EMS being enabled).
Ignition fails to operate

Check that the smart key is located within the vehicle interior, and that it is the correct one for the vehicle.

Insert the smart key into the start control unit (located at out board side of driver instrument panel lower panel), this is an
alternative method to allow Ignition On/Engine Start.



Check that the start button circuit to the CJB is not open circuit or short circuit to power.

Check that the Low Speed CAN network is not malfunctioning, i.e. open circuit or short circuit. This would mean that the
remote keyless entry module, Central Junction Box (CJB) and instrument cluster would be unable to communicate.
Engine fails to crank

If a PATS fault is detected, the LED will flash for 60 seconds at 4Hz with a 50% duty cycle. At the end of this period, the LED
will flash a 2 digit code; this code is repeated 10 times. The meaning of these fault codes along with the frequency of flashing
is given in the accompanying table. As a general rule a fault code of 16 or less will cause the vehicle not to crank. Additionally,
the manufacturer approved diagnostic system should be used to check the instrument cluster, CJB & ECM for Diagnostic Trouble
Codes (DTCs).
One potential occurrence for failing to crank could be due to the P & N start switch (input to the ECM).
Check the Crank Request output from the CJB to ECM is not short circuit to ground or open circuit. www.JagDocs.com
