DOOR LATCHES
The side door latches are sealed units that incorporate separate actuators for locking and superlocking the doors.
Each door latch also incorporates a Hall effect sensor that operates as an ajar switch to provide a door status signal for the CJB.
The driver's door latch incorporates two additional Hall effect sensors to provide signals of lock and unlock selections made with the smart key emergency key blade in the door lock. Turning the top of the emergency key blade rearwards sends a lock signal and turning the top of the emergency key blade forwards sends an unlock signal.
The driver's and front passenger door latches communicate with the CJB via their respective door modules and the medium speed CAN (controller area network) bus.
The rear door latches are connected to the front door modules via a LIN (local interconnect network) bus connection.
On all doors the door ajar Hall sensors are connected directly to the CJB.
Each of the door latches is mechanically connected to a locking button in the top of the door trim panel.
Pressing the locking button down when the door is closed disengages the exterior handle from the door latch to lock the door.
Pulling on the interior handle extends the locking button from the door trim again and re-engages the exterior handle with the door latch, to unlock the door. A second pull on the interior door handle opens the door latch. On all except the driver's door, the doors can be slam locked after pressing the button down while the door is open. For lockout protection, the driver's door locking button cannot be pressed down when the driver door is open.
CLS SWITCH
The CLS switch is a non latching push switch installed between the center face vents on the instrument panel, below the hazard warning switch. The CLS switch allows occupants to centrally lock the vehicle without arming the alarm. When the CLS switch is pressed, a battery voltage signal is connected to the CJB.
SYSTEM OPERATION
The locking system allows the doors and fuel filler door to be centrally locked and unlocked using the CLS switch, the driver's door lock and the smart key.
The system has two locking states: locked and superlocked. Locking the vehicle from inside using the CLS switch puts the system into the locked state. Locking the vehicle from the outside using the driver's door lock or the smart key puts the vehicle into the superlocked state.
When the vehicle is locked, the CJB:
Energizes the lock actuators in the side door latches to disengage the external door handles from the latches.
Energizes the fuel filler door actuator to extend the locking pin to secure the filler door (all except NAS).
Ignores inputs from the upper tailgate external release switch.
The CJB will lock the vehicle regardless of the ignition status. The upper tailgate internal release switch remains enabled and individual side doors can be unlocked using the internal door handle. From the locked state, the vehicle can be centrally unlocked using the CLS switch, the smart key or the driver's door lock.
When the vehicle is superlocked the CJB:
Energizes the lock and the superlock actuators in the side door latches to disengage both the internal and the external door handles from the latches.
Energizes the fuel filler door actuator to extend the locking pin to secure the filler door (all except NAS).
Ignores inputs from both the external and the internal release switches of the upper tailgate.
Ignores inputs from the CLS switch.
The CJB will only superlock the vehicle after the ignition is off and the driver's door has opened. From the superlocked state, the vehicle can be centrally unlocked using the smart key or the driver's door lock.
Repetition Blocking
To protect the door latch actuators the CJB incorporates a repetition blocking feature. The CJB increments an internal counter by one each time an actuation occurs and decrements the counter by one every 8 seconds.
If the counter exceeds 15, the CJB blocks further unlocking commands until the counter returns to 15 or less. The block is ignored if the CJB receives a crash signal or the system goes from superlocked
OK you got the above now the best bit:
