Locks: Description and Operation
Handles, Locks, Latches and Entry Systems
For most markets, the remote central locking system incorporates double locking facilities for optimum security. All locks use the Tibbe key system, using 6 elements and 4 cuts. The keys include 'in-key' transponders which are programmed to the vehicle via the Jaguar Diagnostic System and operate the engine immobilisation system.
The central locking system employs single key access to the driver door, luggage compartment and ignition switch/steering column lock.
When the vehicle is not locked, each door catch can be externally released by the corresponding external door handle which operates via a single rod. When unlocked, or 'single action' locked, the door catches can also be released via the interior handles, each of which operates via a single cable. Operation of the front door interior handles will also unlock the rear doors. Use of the key in the external door barrel, operates the lock via a short rod to provide locking of the door latch. These locking functions can also be achieved by use of the remote transmitter. The luggage compartment can be independently unlatched via a switch located on the driver side lower panel. This will only operate at vehicle speeds below 5 mile/h (8 km/h)
For most markets, a 'drive-away door locking' feature automatically locks all doors and the luggage compartment when the gear selector is moved from the Park position (automatic transmission) or the clutch pedal is depressed (manual transmission).
Key operation
To 'single action' lock or unlock the vehicle, the key is inserted in the door lock, turned towards the front or rear of the vehicle respectively, and released. Holding the key in the lock position will close all windows. Releasing the key stops all operations. 'Single action' locking of the vehicle locks all doors and the luggage compartment, and sets the alarm system. In addition to all of the above functions, double locking prevents the doors opening from the interior. To double lock the vehicle, the key is inserted in the door lock and turned to the unlock (rearward) position, then within three seconds, turned to the lock (forward) position and released. This function can also be activated using the infra red transmitter.
If an attempt is made to lock the doors through either the driver or passenger door interior handle, when that door is ajar, all doors will lock temporarily. If the lock signal was received at the driver door it will unlock, if the lock signal was received at the passenger door all 3 passenger doors will unlock.
The fuel filler flap switch is used to allow the driver to release the fuel filler flap from inside the vehicle. This function can be used at all times providing the vehicle is not locked.
Keyless Entry
The keyless entry remote transmitter operates the following functions:
- Unlocking the driver door.
- Unlocking/locking all doors.
- Unlatching the luggage compartment lid.
- Activate/deactivate the double locking.
- Arms/disarms the anti-theft alarm system and the interior scanning system (if equipped).
- Activates global opening.
- Deactivates a triggered alarm.
Inputs and Outputs
The keyless entry/computer operated lock system receives inputs from the following:
- Ignition switch (positions 1 and 11).
- Courtesy lamp switches.
- Hood switch.
- Luggage compartment switch.
- keyless entry remote transmitter.
The keyless entry/computer operated lock system distributes outputs to the following:
- Driver door module (DDM).
- General electronics module (GEM).
- Rear electronics module (REM).
- Door lock actuators.
- Double locking motors.
- Turning signals.
- Alarm horn.
- Luggage compartment latch.
- Power window motors for global opening.
Transmitter, Keyless Entry Remote
The keyless entry/remote operated lock system is completely independent in function but fully integrated within the anti-theft alarm and DDM. The remote control system consists of a transmitter and an antenna (radio frequency system).
The remote control transmitter for the radio frequency system will operate without the transmitter being directed at the vehicle. The normal range between the transmitter and the antenna will be up to 10 metres for the USA, CANADA and rest of the world. The normal range between transmitter and antenna will be up to five metres for the UK and three metres for JAPAN.
Before the remote control system can be used, each transmitter must be initialized to the vehicle. A maximum number of four transmitters can be initialized to any vehicle. All remote control transmitters must be initialized at the same time.
The keyless entry/remote operated locks will not operate with the ignition switch is in the ignition switch.
Locking and Unlocking
The remote control transmitter is housed separately from the ignition key and contains three buttons (LOCK, UNLOCK, LUGGAGE COMPARTMENT)or four buttons (LOCK, UNLOCK, LUGGAGE COMPARTMENT, PANIC).
To operate the system:
Press the LOCK button once to activate the central locking system and the alarm system.
Press the LOCK button twice within three seconds to activate the central locking system, double locking system, alarm system and the interior scanning system (if equipped).
Press the UNLOCK button once the double locking is reset, the alarm system is deactivated and only the driver door is unlocked (this is programmable using PDU).
Press the UNLOCK button twice within three seconds, will unlock the remaining doors (this is programmable using PDU).
Press the TRUNK RELEASE button once within three seconds releases the trunk.
Press the PANIC button once to trigger the alarm , press the PANIC button again to stop the panic alarm.
Double Locking
Double locking prevents the interior door handles from unlocking the door.
Double locking is activated by turning the key, using the driver door to the unlock position and then to the lock position within three seconds or by pressing the LOCK button twice on the transmitter.
Successful double locking is indicated by the turning signals flashing twice one short flash followed by a long flash.
Double locking will be inhibited if the control module senses a door is open.The DDM receives its input from the driver door ajar switch. The GEM receives it's input from the passenger door ajar switch and the REM receives it's signal from the rear passenger doors.
If the vehicle battery becomes discharged after the double locking has been activated by opening the door with the key this will mechanically deactivate the double locking (only on the door opened).
Driver Door Module (DDM)
The DDM contains a radio receiver that receives a signal from the key entry remote transmitter through the internal DDM antenna. Once a signal has been received the DDM sends the appropriate command to the door lock actuators, the alarm horn, trunk actuator, DDM and the exterior light flashers.
The DDM is equipped with a permanent memory which stores the programmed transmitter(s) in the event of the vehicle battery disconnection.
Antenna, Driver Door Module (DDM)
The antenna is fitted inside the DDM which is situated inside the driver door trim panel. This receives the signal from the key entry remote transmitter and relays it to the DDM except for Japan, South Korea and Singapore a separate RES unit is fitted in the center console.
Global Opening
Global opening operates when the alarm is deactivated. This will open all of the power windows and roof opening panel when fitted.
