The active anti-theft system monitors all doors, hood and tailgate for unauthorized opening. In some markets the anti-theft system also incorporates monitoring of the passenger compartment and vehicle tilt sensing.
The active anti-theft system is controlled by the following body system control modules:
- BCM/GWM
- DDM
- PDM
- Rear Door Module (RDM) - (quantity 2)
- IPC
- RFA.
The BCM/GWM controls the following security functions, in addition to other vehicle functions:
- Single locking, double locking (market dependant) and unlocking (both central unlock and single point entry).
- Monitoring of hood switch, door ajar switches and the tailgate ajar switch of the Central Door Locking (CDL) system.
- Passive Entry Passive Start (PEPS).
- Volumetric sensor.
- Smart key transponder reading.
- BBUS or passive sounder.
- Passive arming and disarming.
- Panic alarm function.
- Passenger compartment lighting.
Depending on vehicle configuration, 2 levels of vehicle anti-theft alarm are available:
- Perimeter sensing mode - Monitors all opening panels.
- Perimeter with alarm sensing mode monitors the passenger compartment for intrusion. Perimeter with alarm sensing mode also incorporates a tilt sensor to monitor if the vehicle is being moved.
Volumetric mode and tilt sensing are not available in certain markets.
Perimeter Sensing Mode
All apertures (doors, tailgate and hood) are monitored for ajar status (doors ajar and latch status change).
A visual (by turn signal indicators) and audible alarm is emitted by an system sounder and vehicle horns in the event of unauthorized access. The indications are market dependant. The alarm is also triggered in the event of an unauthorized start request.
Smart Key
The smart key provides the following functionality:
- Unlock (central unlock or single point entry).
- Single lock and double lock (market dependant).
- Tailgate release.
- Approach lighting.
- Panic alarm.
The lock and unlock switches also control a 'lazy' lock and unlock feature. The 'lazy lock' will automatically close or open the windows with an extended press of the applicable switch. This feature is only available in certain markets and is controlled in conjunction with the door modules.
Never double lock the vehicle with any person or animal inside.
Double locking is only available in certain markets.
The smart key contains an emergency key. This can be used in the event of failure of the smart key or the startup battery to unlock the vehicle. The driver door handle contains a concealed mechanical key barrel which can be used with the emergency key to access the vehicle. This will not disable the perimeter or alarm sensors systems and the visual and audible alarm will be activated when the door is unlocked/opened. To cancel the alarm, the smart key must be held next to the IAU and the ignition switch must be operated.
Emergency Locking
On the inside face of each door there is an emergency key aperture. This is for use with the emergency key in the event of a failure of the startup battery, to lock the vehicle.
Remove the cover and insert the emergency key into the aperture to mechanically lock each door in turn. The driver door must be the last door to be locked. Please make sure that the emergency key is removed from the emergency key aperture before each door is closed.
For additional information, refer to: Handles, Locks, Latches and Entry Systems (501-14 Handles, Locks, Latches and Entry Systems, Description and Operation).
DOOR MODULES
The DDM is shown, the other door modules are similar.
The door modules provide the interface between the door latches and the BCM/GWM. The door modules provide door latches status information and enable the door motors on request from the BCM/GWM.
The rear door modules are also controlled by the BCM/GWM through the High Speed (HS) Controller Area Network (CAN) body systems bus. Additionally, the DDM and thePDM also control the door mirror functions.
DOOR LATCHES
Front right door shown, the other doors are similar.
Each door latch has a micro switch which is monitored by the BCM/GWM.
HOOD LATCH
| ITEM | DESCRIPTION |
|---|---|
| 1 | Hood latch with switch |
| 2 | Hood latch |
The right hood latch has a micro switch. The hood switch is attached to the underside of the right hood latch and operated by movement of the hood latch mechanism. When the hood latch opens, the switch closes and connects a ground to the BCM/GWM.
TAILGATE LATCH
The tailgate latch has a micro switch which is monitored by the BCM/GWM.
BODY CONTROL MODULE/GATEWAY MODULE
The BCM/GWM is the main controller in the system. The BCM/GWM controls the following security functions, in addition to other vehicle functions:
- Single locking, double locking (market dependant) and unlocking (both central unlock and single point entry).
- Monitoring of hood switch, door ajar switches and the tailgate ajar switch of the CDL system.
- PEPS system.
- Volumetric sensor.
- Smart key transponder reading.
- BBUS or passive sounder.
- Passive arming and disarming.
- Panic alarm function.
- Passenger compartment lighting.
The BCM/GWM also has a connection to the Restraints Control Module (RCM). This connection provides the automatic operation of the passenger compartment lights and the turn signal indicators in the event of an accident.
If the BCM/GWM is replaced, the new module will require configuring to the master car configuration. Configuration is done using the Jaguar Land Rover (JLR) approved diagnostic system.
The BCM/GWM automatically arms and disarms the active anti-theft system when the vehicle is locked and unlocked. This is after successful confirmation that a valid smart key has been used.
IPC
The BCM/GWM controls the security system status indicator. The security system status indicator is incorporated in the main display in the IPC.
The IPC also controls the engine immobilization, in conjunction with:
- The BCM/GWM
- The Powertrain Control Module (PCM)
- The Anti-Lock Brake System (ABS) control module.
The PCM controls the engine crank and fuel functions and the ABS control module controls the tilt function. The PCM and ABS control module communicate to each other after the BCM/GWM processes the valid smart key information.
Security System Status Indicator
The security system status indicator is a red Light Emitting Diode (LED) located in the IPC. When the ignition is switched off, the indicator gives a visual indication of the active anti-theft system. The indicator shows if the alarm is set or unset.
In Power Mode 6 (Ignition ON), the security system status indicator provides a visual indication of the status of the passive anti-theft system. If the immobilization system is operating correctly, the LED will be illuminated for 3 seconds after the ignition is switched 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 a Diagnostic Trouble Code (DTC) has been recorded. After the 60 second period, the LED will flash at different frequencies which indicates the nature of the fault.
Operation of the security system status indicator is controlled by the IPC. The IPC varies the flash rate of the LED to indicate the system status of the alarm and the immobilization systems.
Operation of the security system status indicator is also controlled by the BCM/GWM.
| SECURITY SYSTEM STATUS | SECURITY SYSTEM STATUS INDICATOR | SECURITY SYSTEM STATUS INDICATOR FUNCTION |
|---|---|---|
| UNSET | No flash | LED remains off |
| SET - Perimeter alarm mode | Flashing | LED will flash 1 time every 2 seconds |
| SET - Perimeter with alarm sensing mode | Flashing | LED will flash 1 time every 2 seconds |
| ACTIVE - Triggered | Flashing | LED will flash 1 time every 2 seconds |
| UNSET - alarm activated during previous SET cycle | No flash | LED remains off |
SECURITY SYSTEM SOUNDER
| ITEM | DESCRIPTION |
|---|---|
| 1 | Passive sounder |
| 2 | BBUS |
Depending on vehicle configuration a passive sounder or a BBUS is installed. The passive sounder or BBUS is located behind the side secondary bulkhead panel on the driver side.
The passive sounder is connected directly to the BCM/GWM. The BCM/GWM activates the passive sounder as a secondary security sounder when the alarm is triggered.
The BBUS incorporates an tilt sensor which monitors the vehicle attitude. The tilt sensor can detect if the vehicle is being moved, towed or raised. The tilt sensor communicates to the BCM/GWM to indicate a trigger to activate the alarm.
Operation of the BBUS and tilt sensor is controlled by the BCM/GWM on the Local Interconnect Network (LIN) bus. An integral, rechargeable battery power feed is supplied to the BBUS if the vehicle startup battery supply from the BCM/GWM is interrupted.
HORN
The 2 horns are located above the front bumper armature. The horns have a switched power supply through the horn relay located in the Engine Junction Box (EJB). The horns are switched by the steering wheel, connected through the clockspring to the BCM/GWM. The BCM/GWM activates the horns as a secondary security sounder when the alarm is triggered.
VOLUMETRIC SENSOR - IF EQUIPPED
The volumetric sensor is located in a central position in the front overhead console. The volumetric sensor comprises 3 sensors which allow the passenger compartment of the vehicle to be monitored. The BCM/GWM provides a permanent power supply for the volumetric sensor. The volumetric sensor signals are transmitted to the BCM/GWM on a LIN connection.
The volumetric sensors are activated when the vehicle is double locked. The vehicle can be locked and alarmed with the volumetric sensors deactivated. This can be achieved by single locking the anti-theft active system or by deactivating the alarm sensors in the IPC settings menu.
In certain markets (Benelux) the volumetric sensors (if equipped) are activated on single locking as a market requirement.
When the volumetric sensors are active and the startup battery voltage falls below 9V, the BCM/GWM ignores any inputs. This is to prevent false alarm activation.
The BCM/GWM ignores the signals from the volumetric sensor for the first 15 - 30 seconds. This allows time for the passenger compartment to settle and prevent false alarm activation.
If the tailgate is opened by the smart key, the volumetric sensor and the tilt sensor are inhibited until the tailgate is closed.
SMART KEY
PASSIVE ENTRY PASSIVE START SYSTEM
The PEPS system includes enhancements to further improve vehicle security.
The smart key includes ultra wide band technology, designed to combat the latest security threats. Ultra wide band technology includes 2 new passive entry transceivers, which are programed to the vehicle in conjunction with smart keys.
Transit mode has changed to allow passive operation, utilizing only the front passive entry transceiver.
Operation in transit mode as follows:
- Press the hazard warning lamp switch to wake up the BCM/GWM.
- Press the engine stop/start switch with the smart key located in the cup holder close to the Transmission Control Switch (TCS).
DISARMING
The BCM/GWM automatically arms and disarms the anti-theft system when it operates the CDL system. The BCM/GWM also locks and unlocks the Electric Steering Column Lock (ESCL) (if equipped) when it operates the CDL system.
On vehicles without a volumetric sensor, only the perimeter mode is available to monitor the hinged panels and the validity of the smart key.
When perimeter sensing is active, the BCM/GWM monitors aperture ajar switches. The ajar switches are located in the latch mechanisms of the doors, in the tailgate and hood latch.
When volumetric sensors are active, the BCM/GWM monitors the passenger compartment of the vehicle for movement. The volumetric sensor is located in the front overhead console.
When the tilt sensor is active, the BCM/GWM monitors the vehicle for raising using an tilt sensor. The tilt sensor is located within the BBUS.
ARMING
Perimeter mode
The anti-theft active system is armed in the perimeter mode when the vehicle is either locked or double locked. The lock or double lock is by the lock switch on the smart key.
Smart key switch selections are relayed to the BCM/GWM. The lock/unlock switch selection on the exterior door handles are relayed to the BCM/GWM. The signal is sent by the RFA on the HS CAN body systems bus.
Perimeter mode only monitors the hinged panels and validity of the smart key in the RFA.
Perimeter Mode - Vehicles With Passive Entry System
The anti-theft active system is armed in the perimeter mode when the lock/unlock switch on 1 of the exterior door handles is used.
Perimeter With Alarm Sensing Mode
The volumetric sensor monitors the passenger compartment for intrusion. The BBUS (if equipped), monitors also the vehicle attitude when perimeter with alarm sensing mode is active. The BBUS incorporates a tilt sensor.
Perimeter with alarm sensing mode is activated by the following manner:
- A second press of the lock switch on the smart key.
- Using the lock switch on 1 of the exterior door handles, on vehicles with the passive entry system.
The second press of the switch must occur within 3 seconds of the first press. The second press of the lock switch also activates the perimeter sensing double locking feature.
In certain markets (Benelux) the volumetric sensors (if equipped) are activated on single lock as per latest market requirements.
The BCM/GWM arms the active anti-theft system when it single locks or double locks the vehicle, providing all the following conditions are met:
- All doors, tailgate and hood are closed
- The BCM/GWM is not in transit mode.
When the vehicle has successfully completed its locking routine, confirmation will be given by a single short flash of the turn signal indicators. The short flash indicates a single locked condition.
If double locking is activated, then the confirmation will be given by:
- A double flash of the turn signal indicators.
- 1 short flash for locked.
- 1 long flash on completion of double locked.
If ‘audible lock warning’ is enabled, an audible chirp shall also be emitted from the BBUS on double lock. This feature can be turned on and off in the IPC security features menu.
Mislock
When a lock or double lock request is received from a smart key, the anti-theft system remains disarmed if:
- Any doors, tailgate or hood is open/ajar.
- Ignition is switched ON (Power Mode 6).
The BCM/GWM generates a short mislock sound from the BBUS or passive sounder. The turn signal indicators will not flash. Each attempt to lock will be confirmed by an audible chime being emitted.
If the tailgate is opened by the smart key, the volumetric sensor and the tilt sensor in the BBUS are inhibited. The sensors are inhibited until the tailgate is closed.
Disarming
The BCM/GWM will disarm the active anti-theft system to prevent false alarm activation under certain conditions as follows:
- If the vehicle startup battery decreases to less than 9V. If the system is in perimeter with alarm sensing mode the BCM/GWM will remain in perimeter mode only. This prevents false alarm activation because the volumetric sensor cannot operate correctly below 9V.
- If the startup battery voltage decreases from 9.5V to 9V in more than a 30 minute period. The BCM/GWM deactivates the BBUS. If required, the BCM/GWM will activate the horns to sound an audible alarm trigger warning. This prevents false alarm activation.
- At voltages less than 9V, the BCM/GWM will not generate the 'heartbeat' signal to the BBUS. The BBUS interprets this as the BCM/GWM has been tampered with and activates its sounder. If the startup battery voltage subsequently rises to more than 9.5V, the BCM/GWM will re-arm the BBUS.
- If within 40 seconds of unlocking a vehicle a hinged panel is not opened the vehicle will re-lock. The active anti-theft system will re-arm. This prevents leaving the vehicle unlocked and disarmed by accidental operation of the smart key unlock switch/exterior handle.
Alarm
When the alarm is triggered, the BCM/GWM activates audible and visual warnings. The audible warnings are produced by the passive sounder or the BBUS and horns (market dependent). Visible indications are produced using the turn signal indicators.
The BCM/GWM activates the security sounder or the BBUS, the vehicle horns and the visual indications for 30/60 seconds. The time is depending on the market. The activation is stopped for 10 seconds and, if the alarm trigger is still present, the BCM/GWM will cycle again for 30/60 seconds. This will be repeated for up to a maximum of 10 cycles per trigger source of 30/60 seconds for any 1 arming period. This is 3 cycles in certain markets.
The BCM/GWM ignores the trigger cause if:
- The 10 cycles (3 cycles in certain markets) are completed and the alarm trigger is still present.
- Or until the BCM/GWM receives a disarm signal.
If the BBUS is triggered due to tamper detection, the visual indication using the turn signal indicators is not activated.
The alarm can be triggered by:
- Any of the hinged panels being opened.
- Any of the doors being unlocked.
- The volumetric sensor detects a movement inside the vehicle.
- The tilt sensor detects vehicle movement.
- An ignition tamper is detected (invalid smart key).
BBUS
If a BBUS is equipped, it is also armed with the perimeter mode lock request. However, the tilt functionality is not enabled in perimeter mode depending on market/single/double locking latches.
On receipt of the arming signals, the BBUS and the tilt sensor respond with a status message. If the BCM/GWM does not receive the status signals, the BCM/GWM assumes there is a fault. The BCM/GWM responds with a disarm signal to either the BBUS and/or the tilt sensor. The BCM/GWM stores a related DTC. If the BBUS is disarmed when the active anti-theft system is armed and the system is triggered, the BCM/GWM energizes the horn relay. The horns will sound the audible warning in place of the BBUS.
When the BBUS is armed, the BCM/GWM sends a periodic (heartbeat) signal to the BBUS. The signal prompts the BBUS to monitor the startup battery supply and the LIN connection with the BCM/GWM.
The BBUS will operate in the following cases:
- It receives an alarm signal from the BCM/GWM or the tilt sensor.
- The power supply or the LIN bus link to the BCM/GWM is disrupted.
The tilt sensor measures the longitudinal and lateral angle of the vehicle over a range of ±16° from the horizontal. When the active anti-theft system is armed in perimeter with alarm sensing mode, the tilt sensor stores the current vehicle angles in its memory. The tilt sensor monitors the tilt sensor readings. If the vehicle angle changes in either direction by more than the alarm limit threshold, the tilt sensor communicates to the BCM/GWM. The BCM/GWM activates the BBUS.
If the alarm is active and the startup battery or the BBUS is disconnected, the BBUS continues to sound. The turn signal indicators will not flash.
Panic Alarm
A panic alarm feature allows the vehicle alarm to be activated using the smart key. The panic alarm switch, identified by a triangle symbol, can be operated and held for more than 3 seconds to activate the vehicle alarm.
To cancel the panic alarm feature perform 1 of the following:
- Operate the panic alarm switch 3 times.
- Press and hold the panic alarm switch for 3 seconds.
- Operate the ignition switch.
To prevent accidental cancellation, the panic alarm cannot be canceled within 5 seconds of being activated.
SMART KEY ADDITIONAL FEATURES
In addition to the lock and unlock switches, the smart key has convenience switches.
Headlamp Convenience
A headlamp convenience switch can be pressed to operate the headlamps to assist departure or approach to the vehicle. A single press of the switch will operate the headlamps for approximately 25 seconds, after which time they will automatically turn off. A second press of the switch will turn off the headlamps if the 25 second period has not been reached. Operating the ignition switch within the 25 second period will also turn off the headlamp convenience feature.
Convenience Mode
When the vehicle is unlocked using the unlock switch on the smart key, the vehicle's electrical system initiates convenience mode.
The following systems become active in convenience mode:
- Memory - Seat adjustment and mirror position
- Passenger compartment and exterior lighting
- Audio system
- IPC message center
- Horn
- 12V accessory socket.
Single Point Entry
The single point entry feature only unlocks the driver door, all other doors remain single locked. A single press of the unlock switch on the smart key will unlock only the driver door. A second press is required to unlock the remaining doors and the tailgate.
If the vehicle is double locked, the first press of the unlock switch on the smart key unlocks the driver door.
The remaining doors revert to the single locked state and can therefore be unlocked using the following:
- A further press of the smart key unlock switch.
- The CDL lock/unlock switch on the driver door.
- The passenger compartment door handles on the passenger doors.
- Passive entry by any passenger door.
Access to the tailgate can be achieved by:
- A further press of the smart key unlock switch.
- The smart key tailgate open switch.
- The tailgate open switch on the instrument panel.
- The CDL lock/unlock switch on the driver door.
- The passenger compartment door handles on the passenger doors.
- Passive entry by any passenger door.
- Passive entry by the tailgate open switch.
Changing from CDL to single point entry can be performed by:
- Pressing the lock and unlock switches on the smart key simultaneously. The turn signal indicators will flash to confirm that the function change.
- Using the IPC menu.
Global Open/Close
The global open/close feature is not available in all markets.
A global open and close feature can be operated from the smart key. This feature allows the windows to be opened/closed by a single press of the lock or unlock switch. The switch must be pressed and held for more than 2 seconds to activate the global open/close feature. The windows must be initialized for the global functionality to work.
ULTRA WIDE BAND OPERATION
With the introduction of ultra wide band technology, recognising the position of the smart key requires 2 pieces of distance information. The 2 passive entry transceivers are located in the headliner, 1 at the front and 1 at the rear. The location enables full coverage inside and outside of the vehicle.
The following process takes place to validate the smart key:
- The RFA receives a door lock/unlock request.
- On receipt of the door lock/unlock request, challenge data is sent out from the RFA to the smart key. The challenge data is sent by the LF antennas at 125 kHz.
- The smart key responds to the LF signal, processing the received message and replying to the vehicle using a separate Radio Frequency (RF) channel. Depending on market the RF channels are 433 MHz or 315 MHz.
- This response is received by the remote function receiver.
In addition the RFA sends a separate challenge by the passive entry transceivers to the smart key. The RFA sends this data in order to authenticate and obtain the smart key position with accuracy, using the following process:
- The challenge data is sent from the RFA through LIN to the passive entry transceivers.
- The passive entry transceivers process and transmit the data to the smart key. The data is sent by a separate RF signal at 3.99 GHz (4.5 GHz in China).
- On receipt of the signal the smart key responds with an authentication message back to the passive entry transceivers. The smart key responds by an RF signal through the LIN bus connection.
When the smart key is validated the system operates in the normal way.
LOW FREQUENCY ZONES
The message contained in the beacon signals varies based on each transmitter zone. For example, the message could vary based on if the zone was inside or outside the vehicle. This capability allows the smart key to send specific answers, triggering actions such as opening the passenger door or starting the engine.
A common security threat consists of relaying the messages exchanged between the vehicle and the smart key over long distances. This message range is indefinite, depending on the technology used. The attack is instigated by intercepting the beacon signal from the LF antenna in the vehicle to the smart key.
The security threat equipment used to intercept the messages is used to gain illegal entry to the vehicle and activate the passive start system.
SECURITY ENHANCEMENTS
To avoid security threats 1 option is to measure the real physical distance between the vehicle and the smart key. If the vehicle detects that the smart key is not physically close it will simply ignore the command received.
There is 1 technique which consists of measuring the time of flight of the RF signal. The measurement of the time is used to estimate the distance between the transmitter and the receiver.
The use of 'Time Of Flight' and ultra wide band technology is designed to efficiently combat security threats. This provides accurate data transfer and message timing. Data transfer operates over a frequency range of 3.99 GHz (4.5 GHz in China) and a bandwidth of 500 MHz.
The ultra wide band signal consists of narrow pulses, making it tolerant of multi-path and in-band interference. The deployment of this technology makes illegal entry and starting attempts much more difficult to achieve.
Ultra wide band technology used in Jaguar Land Rover (JLR) vehicles is very low power and therefore short range. The vehicle system is configured to only take action when the measured distance is no more then 3 m (9.8 ft).
Ultra wide band is capable of achieving a 10 cm (0.32 ft) accuracy. This allows very accurate zones, triggering the lock release mechanism only when the vehicle user is within close proximity to the vehicle.
SECURITY THREATS
Current PEPS system vehicles are equipped with several LF 125 kHz antenna transmitters. The LF antennas cover specific zones inside and outside of the vehicle. The LF antennas send beacon signals. If the smart key is within range (1 m (3.2 ft)) of an antenna the ‘sleeping’ smart key picks up the LF signal. This signal wakes the smart key and triggers the processing of the received message. The smart key replies to the vehicle using a separate RF channel.
The smart key RF channel is 433 MHz in Europe (EU), 315 MHz in North American Specification (NAS) and Rest of World (ROW) markets.
