Door Latches
The door latches have two integral motors, which can be used to put the latch into three different mechanical states:
- Unlocked - doors can be opened from the inside or outside release handles.
- Central (Single) Lock - doors can only be opened from the inside release handle.
- Central Arrest (Double Lock)- doors cannot be opened from any door handle.
Micro-switches for the door contacts are integrated in the door latches. On the driver's door latch assembly, the key lock/unlock micro-switches are also included.
The central locking motors can be driven directly from any mechanical state to any other mechanical state; there is no need to go via any intermediate states.
NOTE:
Not all production vehicles have a double lock feature.
