Door Locking Function; External Controls; Internal Controls - Fiat TIPO 2016 Manual

Door locking function.

The electric door locks are controlled by the BCM. This locks and unlocks the doors on the basis of
two control types: external and internal.

External controls.

The external door locking/unlocking commands can arrive from the following components:
Closing/opening buttons on RF remote controls of keys

Key cylinder on driver door handle

The BCM receives the RF signals from the locking/unlocking buttons on the remote controls via an
aerial. The movement of the key cylinder on the driver door handle is detected by a switch connected
electrically to the BCM.

Internal Controls.

The internal door locking/unlocking commands can arrive from the following components:
 Button on the central control panel.
 Car speed above 20 km/h (speed information for BCM via CAN).
Door unlock request from FPS (Fire Prevention System).

In every ignition switch position (OFF, RUN, START) the BCM, before sending the door
locking/unlocking command, checks the status of the doors (open or closed) through the switches in
the locks.
