Locking System: Notes
The locking system allows the doors and fuel filler flap to be centrally locked and unlocked using the CDL switch, the drivers door lock and the remote handset. The system has two locking states: locked and superlocked. Locking the vehicle from inside using the CDL switch puts the system into the locked state. Locking the vehicle from the outside using the driver's door lock or the remote handset puts the vehicle into the superlocked state.
When the vehicle is locked, the BCU:
- Energizes the lock actuators in the side door latches to disengage the external door handles from the latches
- Energizes the fuel filler flap actuator to extend the locking pin to secure the filler flap (all except NAS)
- Ignores inputs from upper tail door external release switch.
The BCU will lock the vehicle regardless of the position of the ignition switch and whether the key is in the ignition switch or not. The upper tail door 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 CDL switch, the remote handset or the driver's door lock.
When the vehicle is superlocked, the BCU:
- 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 flap actuator to extend the locking pin to secure the filler flap
- Ignores inputs from both the external and the internal release switches of the upper tail door
- Ignores inputs from the CDL switch.
The BCU will only superlock the vehicle after the ignition key has been removed from the ignition switch and the driver's door has opened. From the superlocked state, the vehicle can be centrally unlocked using the remote handset or the driver's door lock.
