Handles, Locks, Latches And Entry Systems; Central Locking - Ford Ranger 2022 Manual

4.12 Handles, Locks, Latches and Entry Systems

4.12.1 Central Locking

NOTE: Additional locks will not be covered by the
vehicle alarm or operate BCM controlled lighting.
The central locking function is controlled by the
BCM (located under the instrument panel). The
vehicle locks are operated by field effect
transistors (FET's) in the BCM – these are only
capable of powering one lock each.
It is possible to add an additional lock(s) with the
use of relays triggered by the BCM outputs.

NOTE: The location of additional relays should
be considered carefully. A suitable mounting
location away from the passenger compartment
will allow for a safer install and reduced noise in
the passenger compartment.
Depending on the functionality required, the pins
used will emulate the basic locking/unlocking
operation of an existing lock. The coil of the
additional relays (i.e. one relay for lock all, one
relay for unlock all) should be added across the
relevant pin and a suitable ground point. Power
(B+) for the additional relays should be taken
from a suitably fused B+ feed.
Relay selection for installation of an additional
lock(s) must parallel the run time of the BCM
surface mount relays.
