Operation

CLS OPERATION
The CLS allows the doors and, where applicable, the fuel filler door, to be centrally locked and unlocked using the remote handset, the CLS switches or the door lock. The CLS has three locking states: internally locked, externally locked and superlocked.

Configurable CLS features include automatic speed locking, automatic relocking and SPE. All vehicles incorporate crash unlocking.

The internally locked state is activated with a single press of the CLS lock switch. The method of activating the externally locked and superlocked states is market dependent:
^ In all markets except North American Specification (NAS), a single press of the lock button on the remote handset,or a single lock turn of the door lock, activates the superlocked state. A second press of the lock button on the remote handset, or a second lock turn of the door lock, within 2 seconds of the first, changes the CLS to the externally locked state.
^ In NAS markets, a single press of the lock button on the remote handset, or a single lock turn of the door lock,activates the externally locked state. A second press of the lock button on the remote handset, or a second lock turn of the door lock, within 2 seconds of the first, changes the CLS to the superlocked state.

In the internally locked state:
^ The exterior door handles are disengaged from the latches, to prevent the doors being opened from outside the vehicle.
^ The CJB ignores inputs from the tailgate release switch, which prevents the tailgates being opened.
^ The doors can be opened using the internal door handles.
^ The vehicle can be unlocked using a single press of the CLS unlock switch, a single press of the unlock button on the remote handset or a single unlock turn of the door lock.

In the externally locked state:
^ In addition to the conditions adopted for the internally locked state, the CJB also ignores inputs from the CLS lock and unlock switches.
^ The vehicle can be unlocked using a single press of the unlock button on the remote handset or a single unlock turn of the door lock.

In the superlocked state:
^ In addition to the conditions adopted for the externally locked state, the CJB activates:
^ The superlock motors in the door latches, to disengage the interior door handles.
^ The fuel filler door lock motor (where fitted), to secure the fuel filler door.
^ The vehicle can be unlocked using a single press of the unlock button on the remote handset or a single unlock turn of the door lock.

When the CLS lock switch is used, the CJB will internally lock the vehicle regardless of the position of the ignition switch,with or without the key in the ignition switch and with or without the engine running.

When the remote handset or the door lock is used, the CJB will only lock or superlock the vehicle provided the ignition key has been removed from the ignition switch.

When the vehicle is externally locked or superlocked, the CJB flashes the turn signal lamps three times, for 500 milliseconds, with a 500 milliseconds pause between flashes. When the vehicle is unlocked using the remote handset or the door lock, the CJB flashes the turn signal lamps once, for 3 seconds.

Mislock
A mislock occurs if the CJB receives an external lock or superlock request when any hinged panel is ajar, an invalid key is in the ignition switch or the repetition blocking limit for the door latches is reached. To indicate a mislock the CJB uses the horns to produce a 100 milliseconds 'chirp' and withholds flashing of the turn signal lamps.

If a mislock occurs because an invalid key is in the ignition switch or a hinged panel is ajar, the CJB still externally locks any doors that are closed. The closed doors are only externally locked, even if the original request was for superlocking.

If a mislock occurs because a hinged panel is ajar, when the hinged panel is subsequently closed the CJB maintains the current locking state until it receives another external lock or superlock request.

SPE
When SPE is enabled, an unlock command from the remote handset or the door lock only unlocks the driver door. To unlock the remaining doors a second unlock command from the remote handset, the door lock or the CLS unlock switch is required.

For each remote handset, SPE can be toggled on and off by pressing and holding the lock and unlock buttons on the remote handset at the same time, for 3 seconds, with the vehicle either locked or unlocked and the key removed from the, ignition switch. Confirmation of the change to the SPE setting is provided by the vehicle locking and then unlocking in the selected mode.

Speed Dependent Locking
When speed dependent locking is enabled, the CJB internally locks the doors when the vehicle speed exceeds 8 km/h (5 mph) with the driver door closed and the engine running. If the vehicle slows down or stops, then increases to more than 8 km/h (5 mph) again, the CJB internally locks the doors again only if a door was opened while the vehicle speed was less than 8 km/h (5 mph). When the key is removed from the ignition switch, the CJB returns the vehicle to the previous unlocked state, i.e. unlocks all the doors, or just the driver door if SPE is enabled.

Speed dependent locking can be enabled and disabled in the customer settings menu.

Crash Unlocking
When the ignition switch is in position II, if a crash that triggers the air bags occurs the CJB unlocks all of the doors. After 3 seconds, the CJB unlocks the doors again, in case a lock button is pressed during the crash, by flailing limbs for example. The CJB is informed of the crash by a status message from the restraints control module, on the medium speed CAN bus, which changes from 'no crash' to 'crash'. The CLS will also perform crash unlocking if a 'no crash' status message is not received every 500 milliseconds.

The vehicle cannot be centrally locked again until the status message has been reset to 'no crash' by the restraints control module.

Repetition Blocking
To protect the CLS motors and actuators from operating abuse, the CJB incorporates a repetition blocking feature, which limits the maximum operating rate of each motor and actuator. The lock motor in each door latch also incorporates thermal protection.

CLS Motor and Actuator Operating Parameters





Nominal operating current is at 23 degree C (73 degree F). Stall current is for 15 volts at -40 degree C (-40 degree F)

Lockout Protection
The vehicle cannot be locked or superlocked when the driver door is open. If an attempt is made to lock or superlock the vehicle, with the key lock or the remote handset, while the driver door is open, the CJB ignores the request.

Automatic Relock
If the CLS is unlocked, using the remote handset or the key lock, and a door or the tailgate is not opened, or the key is not put in the ignition switch, within 1 minute, the CJB automatically locks or superlocks the vehicle again, depending on the previously locked mode. Automatic relock is designed to prevent inadvertent unlocking and disarming the vehicle by accidentally pressing the unlock button on the remote handset.

Delivery Mode
When the vehicle is in the delivery mode, SPE is enabled and global unlocking with the remote handset or the key lock is disabled. The speed locking function is also disabled, but crash unlocking is retained.
