4.14 Handles, Locks, Latches and Entry Systems
4.14.1 Door Removal or Modification
In the event of the requirement to remove the
doors for derivatives requiring no doors, certain
circuits will need to be linked to ensure door ajar
warnings do not appear on the Instrument Cluster.
The interior light will also stay on if this is not done.
It is possible to maintain a certain state by
configuring the Body Control Module (BCM) C3
in the following way.
•
C3-44 Front Left
•
C3-34 Front Right
•
C3-50 Ajar lift gate switch
•
C3-35 Ajar left side cargo switch
•
C3-51 Ajar left side cargo switch
4.14.2 Central Locking
Locking is controlled by the BCM. There is current
sensing on certain locking circuit pins as part of
the security system – if these are tampered with,
locking cannot be guaranteed.
However, it is possible to add an additional lock(s)
– see also the section covering the ‘third button
on key fob’ – but only by utilizing relays (the
electric locks are operated by surface mounted
relays in the BCM – these are only capable of
powering one lock each, in addition to which the
output of these devices is current-sensed to check
it is within minimum and maximum limits: I) to
verify operation, and ii) as part of the security
system).
Depending on functionality required, the pins used
will emulate the basic locking/unlocking operation
of an existing door. Note, however, that any
additional locks will not be covered by the vehicle
alarm or operate BCM controlled lighting. It would
be necessary to splice into either the BCM
connector or the in-line connector for the door
jumper harness. The coil of the relay (max.
300mA) should be added across the relevant pin
and ground (i.e. one relay for lock all, one relay for
driver door unlock etc).
The use of Ford Transit lock mechanisms is
strongly recommended as the BCM is designed
to drive these latches for the correct amount of
time.

Locking Configurations
The following list details
specific locking scenarios that have been noted
by customers:
1. Raid locking or drive away locking for taxi and
parcel van usage – this is a configurable
parameter in the BCM (Ford Dealerships can
set this). There is also the option to configure
via the instrument cluster once the
configurable parameter has been set.
2. Slam locking – this is a configurable parameter
in BCM (dealerships can only switch off this
feature, but not switch on).
3. N1 lock reconfiguration into no deadlocks – this
can be reconfigured to be central-locking only
by a Ford Dealer (via Dealership hotline).
4. Auto unlock - There is an option to configure
central unlock where the drivers door, when
opened, will automatically unlock all doors
except any doors controlled by the third button
on the key fob.
Drive-Away Locking Disable
The following parameter (automatic locking by
speed) is configured as follows:
•
IDS parameter 32 - Change 0x02 [on] to 0x01
[off].
