Only the individual door will lock
mechanically and stay locked (
i.e. no central

) – there is no reverse cycling
because there is no lock/ unlock switch that the
BCM can detect.
NOTE:
When a reverse cycle condition occurs by remote,
the mislock warning is sounded to alert the
customer that locking was unsuccessful. No
flasher feedback is given
.
Auto-Locking on Drive Away:
When vehicle is unlocked then it will be
automatically central locked when all doors are
closed, ignition is turned ON and the vehicle speed
goes above 12 Kmph.
The doors will be relocked after any door
has been opened, when the doors become closed
again and vehicle speed goes above 12 Kmph.
NOTE:
If the vehicle speed signal is missing, the auto
lock feature will be disabled.
If diagnostics is monitoring the crash input line
and there is problem with this circuit, the auto
lock feature will automatically be disabled. The
airbag / restraints warning light should flash to
alert an issue with the crash input line.
Crash Unlocking:
The vehicle is fitted with an inertia switch.
On a crash event, the switch is activated then the
BCM will unlock all the doors. The crash input
should be scanned for every 100ms.
The system will unlock all doors
automatically when an impact to the vehicle occurs
and ignition is ON .If the vehicle is locked and the
crash input senses the crash signal (i
.e. inertia
switch activation
) the vehicle will initiate the unlock
process within 100ms.
In the event of the inertia switch being
activated, the hazard lamps and indicators, all
three roof lamps will switch on. They can only be
switched off when the vehicle user de-activates the
inertia switch. During crash unlock activated the
drive away locking is disabled.
Auto Relocking
:
After the vehicle has been central locked
by remote and if a remote unlock is requested, the
required door(s) unlock. After this unlock action, if
no door ajar input is detected (
i.e. no door is
opened
) or if no ignition transition to Run/ Start is
detected, then the doors relock after 45 seconds.
