System Operation

Central Locking System - Manual Operation

The central locking system provides the option of 2 or 3 manual locking modes, dependent on the vehicle specification.

The locking modes are activated using the instrument panel central locking switches, front door central lock/unlock buttons, or the remote handset lock/unlock buttons:

When the vehicle is externally locked, the CJB flashes the direction indicators once for 250 milliseconds. When the vehicle is double locked, the CJB flashes the direction indicators twice for 250 milliseconds with a 250 millisecond pause between flashes. When the vehicle is unlocked with the remote handset, the CJB flashes the direction indicator lamps twice for 250 milliseconds with a 250 millisecond pause between flashes.

The remote handset may be configured by the driver for single point entry or global entry, by simultaneously pressing the remote handset lock and unlock buttons for 4 seconds. The vehicle must initially be in an unlocked state. The direction indicators will flash twice for 250 milliseconds with a 250 millisecond pause between flashes to confirm the mode change.

The vehicle will also lock and then unlock in the selected mode.

When single point entry is enabled, an unlock command from the remote handset will only unlock the driver's door, tailgate and the fuel filler door. To unlock the remaining entry points, a second unlock command from the remote handset or the instrument panel central unlock switch is required.

Additional options for speed dependent locking and automatic relocking modes may be configured by the dealer. All vehicles incorporate an automatically operated crash unlocking mode.

Internally Locked Mode

The internally locked mode is activated by a single press of a front door central lock/unlock button. When in the internally locked mode:

Externally Locked Mode

The externally locked mode is activated by a single press of the remote handset lock button. When in the externally locked mode:

Double Locked Mode

The double locked mode is activated by pressing the remote handset lock button twice within 3 seconds. When in the double locked mode:

For all UK, Europe and ROW specification vehicles, a single press of the remote handset lock button will externally lock the vehicle to disengage the exterior handles, and will arm the active anti-theft system.For additional information, refer to: (419-01A Anti-Theft - Active)

For NAS, Japan and Gulf specification vehicles, a single press of the remote handset lock button will externally lock the vehicle to disengage the exterior handles, and will arm the active and passive anti-theft system. For additional information, refer to:

Anti-Theft - Active (419-01A Anti-Theft - Active, Description and Operation),
Anti-Theft - Active (419-01A Anti-Theft - Active, Description and Operation),
Anti-Theft - Active (419-01A Anti-Theft - Active, Description and Operation),

Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation),
Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).

For all vehicles except NAS, Japan and Gulf specifications, pressing the remote handset lock button twice within 3 seconds will double lock the vehicle to disengage the interior and exterior handles, and will arm the active and passive anti-theft system. For additional information, refer to:

Central Locking System - Automatic Modes

The central locking system features automatic modes to control the vehicle entry points, and provide protection for the system components.

The central locking system incorporates the following automatic modes:

Mislock Mode

A mislock occurs if the CJB receives an external lock or double lock request when a hinged panel is ajar. To indicate a mislock the CJB sounds the horns to produce a 100 millisecond 'chirp'.

If a mislock occurs due to an external lock request when a hinged panel is ajar, the CJB will not carry out a lock request on any access points.

Speed Dependent Locking Mode

When speed dependent locking is enabled the CJB will internally lock all the doors when the vehicle speed exceeds 8 km/h (5 mph) with all the doors closed and the engine running. If the driver or front passenger door is opened and then closed, when the vehicle slows down or stops and then increases to more than 8 km/h (5 mph) again, the CJB will internally lock the doors.

Speed dependent locking may be enabled or disabled by the dealer using the Land Rover approved diagnostic system.

Crash Unlocking Mode

With the ignition in power mode 6 (Ignition), if a crash occurs that triggers deployment of the air bags, then the CJB will unlock all of the doors. The CJB is informed of the crash by a status message from the RCM (restraints control module) on the medium speed CAN bus that changes from 'no crash' to 'crash'.

The central locking system will also perform crash unlocking mode if a 'no crash' status message is not received from the RCM every 500 milliseconds. For additional information, refer to: (501-20A Safety Belt System)

Repetition Blocking Mode

To protect the central locking system motors and actuators against system misuse, the CJB incorporates repetition blocking to limit the maximum operating rate of each motor and actuator. The lock motor in each door latch also incorporates thermal protection.

Lockout Protection Mode

The vehicle is not able to be locked using a front door central locking button if any door is open.

If an internal lock request is received from either of the front door central locking buttons, the CJB will centrally lock the vehicle and then centrally unlock the vehicle if any door is open.

If a front door is open and the open door central locking button is pressed and held in the locked position, the open front door may remain in the locked state. When the open door is subsequently closed, the CJB will centrally unlock all doors.

Automatic Relock Mode

Automatic relock prevents accidental operation of the remote handset buttons that will unlock and disarm the vehicle.

When the central locking system is unlocked using the remote handset, and a door or tailgate is not opened or the remote handset is not placed in the start control unit within 1 minute, the CJB will automatically lock or double lock the vehicle again, depending on the previously locked mode.

Transport Mode

All new vehicles are delivered from the factory in transport mode. Transport mode replaces the traditional transit relay and inhibits a number of electrical systems and features to reduce quiescent drain from the battery during delivery. When the vehicle is in transport mode 'transp' is displayed in the instrument cluster odometer. Single point entry is enabled and global locking and unlocking using the remote handset is disabled.

The speed locking mode is also disabled, but crash unlocking mode remains enabled.

To remove the vehicle from transport mode, the Land Rover approved diagnostic system must be connected during the PDI (pre-delivery inspection). For further information, refer to the PDI manual.
