DESCRIPTION AND OPERATION

Operation

General
Electric window operation using the window switches is enabled while the ignition switch is in positions I and II, and 
for 16 minutes after switching from position I to position 0. Window operation is immediately disabled when a front 
door is opened

When the switches in the driver's door are used to operate the passenger windows or the child lock, the driver door 
module outputs a related message on the P bus. The passenger door module or the BCU respond to the message 
by operating the appropriate window or the child lock function. While the child lock is engaged, the BCU ignores inputs 
from the rear window switches, and the driver door module illuminates a LED in the child lock switch.

End of Travel Shut off
End of travel shut off for the window motors is determined by monitoring the current draw of the motors. Each time it 
switches on a window motor, the door  or BCU measures the window motor current for 22 milliseconds, in 2 
milliseconds intervals. The maximum value measured within that time is stored as the switch-on current, which must 
be 5 A minimum. When the window motor current next exceeds the switch-on current minus 2 A, the door /BCU 
assumes the window has reached the end of its travel and, after 0.5 second, switches off the power supply to the 
window motor, even if a window switch is still being activated.

Measuring the switch-on current for each switching operation automatically compensates for changes of load with 
varying ambient conditions etc.

To protect the window motors from overheating if the end of travel shut off function fails, window motor activation in 
both directions is limited to 8 seconds.

One-shot Opening and Closing
One shot opening and closing is activated by selecting the second switching positions on the window switch. One-
shot opening and closing is enabled on all windows except on Australia models. On Australia models, all one-shot 
operation is disabled except for driver's window closing.

Anti-trap
The anti-trap function is enabled for window closing in both the inching and one-shot modes. If an anti-trap sensor is 
activated while a window is closing, the window motor is reversed for 0.5 second.

UK models feature a longer reversing time after a trap detection. The reversing time is proportionate to the preceding 
closing time and varies between 0.5 and 2.0 seconds.

In an emergency, e.g. if the anti-trap sensor is faulty, the anti-trap function can be overridden by holding the window 
switch in the one-shot closed position.

Convenience Opening and Closing
Convenience opening and closing is enabled provided the ignition switch is not in position I or above. The windows 
and sunroof (where fitted) can be opened and closed in sequence, while unlocking and locking the vehicle, using the 
driver's door lock or the remote handset.

Convenience closing begins after a time delay of 1.5 seconds when the door lock is held in the lock position or the 
remote handset lock button is pressed and held. The anti-trap function is enabled during convenience closing. The 
closing operation also stops immediately the door lock is released from the lock position or the remote handset lock 
button is released. The window motors are switched in pairs, with the rear ones switched first followed 1 second later 
by the front ones. The sunroof begins closing when all of the windows are closed or 3.5 seconds after convenience 
closing started, whichever occurs first.

There is no convenience closing on NAS vehicles.
