Door Latches

The door latch mechanisms (driver and passenger) contain micro-switches for door position information. The micro-switches are open (Signal-High) when the doors are closed and are closed (Signal pulled low to ground) when the doors are open.

The Drivers door Lock/Unlock switch provides a Low signal to indicate position request.

Door Lock Motors (one Lock and one Double lock) have polarity reversed by the BC1 to operate in either direction. The motors and latch mechanism provide no feedback to the BC1 as to position and are driven with each lock or unlock request irrespective of their current position.

To avoid overloading the motors are blocked out after 10 operations in 1 minute. The motors will be placed in the unlock state for approximately 1 minute.
