4.6 Handles, Locks, Latches and Entry Systems
4.6.1 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 surface mounted
relays 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.
