POWER WINDOWS

CIRCUIT OPERATION

1

CIRCUIT OPERATION

The window lift system will provide one touch or inch
mode on all windows and will have the anti–trap
function (when initialised) on close.

Initialised window operation.

Selection of any* aperture switch, in either direction,
for less than 0.4 seconds shall initiate the “one
touch” mode of operation. That aperture will be
driven in the direction selected until a trap
(obstruction) is detected (close only) or the motor
stalls. This mode will be cancelled by the operation
of the associated switch in the opposite direction. If
the associated aperture switch is operated in the
opposite direction then the window will be driven in
that direction according to the requirements for one
touch/inch mode operation.

* Rear window one touch up is a programmable
feature.

Selection of any aperture switch for greater than 0.4
seconds will cause that aperture to operate in the
“inch mode”. The aperture will move in the selected
direction until a trap (obstruction) is detected (close
only), the limit of travel is reached or the switch is
released.

All windows will operate independently from each
other and may operate in parallel. In case of conflict
between switches, those in the centre console switch
pack will have priority.

The window lift system will only be active under the
following conditions:

a) while auxiliary is on, ie, the window system will not
be active during crank. Any one touch operations will
be cancelled when ignition 1 turns off during crank.

b) for the first 45 seconds after auxiliary has been
switched off, the one touch up and down functions
will not be available during this time period. If, during
the above 45 second time period, the drivers door is
opened, the window system will remain active for a
further 45 seconds from the door opening or until the
door is closed again, whichever is sooner. If during
either of the 45 second time periods a door lock
signal is received, then the timer will be cancelled
and therefore the window lift system will no longer be
active.

The rear windows can be prevented from being
operated from their local switch by the rear inhibit
switch in the centre console. In the event of a centre
console serial link failure being detected, the local
rear window switches will default to inhibited.

Operation of the driver’s window down switch will
cause the drivers window to move in the down
direction until the switch is released (unless in the
one touch mode), the up switch is operated, or until
a stall condition is detected (i.e. the window is fully
open).

Operation of the drivers window up switch will cause
the window to operate in the close direction until the
switch is released (unless in the one touch mode),
the window down switch is operated, a trap condition
is detected, or until the motor stalls (i.e. the window
is fully closed).

Market Deviations:

a) USA/Canada/Germany:

The system will only be active when the auxiliary
(ignition 1) is on, or for the time between switching
the auxiliary feed off and opening either of the front
doors, but not exceeding 45 seconds.

b) Australia: One touch operation will only be
available for the drivers window.

c) Germany: The back off distance from a trap
condition will be 200mm.
