Central Locking System
Description
Thecentral locking system consistsofmotoroperated lock
actuators in both doors, the boot and the fuel flap
mechanism. The central locking control module is located
inside the drivers side 'A' post.
Each motordriven lock actuator incorporatesa microswitch
which will signal a change of state when any motor runs
to drive the actuator. The microswitches are of the
changeover type and provide an earth for the lock or
unlock signals to the control unit.
The two door lock inputs to the control unit are connected
together so that operation of either door lock with the
ignition key will simultaneously operate the other door
lock. Similarly, the unlock inputs to the control unit are
also connected together for simultaneous operation.
The boot w i l l remain locked or w i l l be unlocked
simultaneously with the doors dependant on the boot lock
position. With the boot key turned clockwise, the boot
lock operates in unison with the doors. With the boot key
turned anticlockwise, the boot lock cannot be unlocked
using the central locking system.
The boot can be opened at any time using the ignition key
irrespective of the central locking status.
