ELECTRIC WINDOWS - SUNROOF
Electric windows: Role of components
●The control panel on the driver's side enables all of the windows to be opened or closed (on the driver's and
passenger's side).
●The passenger electric window switch only lowers or raises the window on the passenger side.
●The UCH controls the operation of the one-touch and anti-pinch control windows.
●The electric window winder motor enables the window to be opened or closed.

ELECTRIC WINDOWS - SUNROOF
Electric windows: Function
Types
The vehicle can be fitted with two types of front window winders:
–Driver's and passengers' electric windows.
–Driver's anti-pinch and one-touch electric window / passenger's electric window.
Electric windows
The motor feed goes via the switch. The switch reverses the polarity to the motor terminals to lower or raise the
window.
One-touch electric window
The UCH controls this window, both its upward and downward movement, in manual or automatic mode (one-touch).
The UCH can only be controlled by unstable position switches (one up position, one down position). The electrical
signal received by the unit means that the input used is connected to earth.
The switch technology employed means that automatic mode cannot be activated directly (double contact
technology). That is why the electric window switches have two up positions (contacts) and two down positions
(contacts).
Electric mode is activated first (1
st contact) followed by one-touch mode (2nd contact). The direction of movement of
the window is determined by the first input (connection to earth).
First example
Switch pressed in the down direction:
1
st contact = down switch earthed
2nd contact = up switch earthed
The electronic unit activates lowering of the window in one-touch mode.
Second example
Switch pressed in the up direction:
1
st contact = up switch earthed
2nd contact = down switch earthed
The electronic unit activates raising of the window in one-touch mode.
ANTI-PINCH
The anti-pinch function is a statutory requirement, which is also managed by the electronic unit. This stops the
window rising in one-touch mode when it meets an obstacle (e.g. fingers, branches, etc.)
On detecting an abnormal force (more than 80N) in a 250 mm area (between the upper stop of the window and the
window), the system causes the window to lower approximately 50 mm.
WARNING
The anti-pinch function only works if the windows have been correctly initialised (see Initialisation).

INHIBITING THE ANTI-PINCH FUNCTION
The window or window mechanism may be subject to various mechanical problems (jammed by ice, snow or
mechanical distortion due to an accident), which can trigger the anti-pinch function. It is possible to inhibit this
function so that the window can be closed.
Procedure:
1) Closing the window in one-touch mode. The window arrives at the point of resistance, then drops back a few
centimetres.
2) Close the window in one-touch mode. The window arrives at the point of resistance again, then drops back a few
centimetres.
3) Close the window, the anti-pinch function is inhibited. The window closes in manual mode continuously without
the anti-pinch function.

ELECTRIC WINDOWS - SUNROOF
Electric windows: Initialisation
Procedure:
Raise the window to the upper limit and maintain the feed at the upper stop for at least 2 seconds.
Causes of loss of initialisation:
–The electronic unit feed is cut off while the electric window is operating or when the UCH is authorising the
operation.
–The theoretical maximum travel goes beyond the upper stop.
–If the correct position was not initialised (obstacle), operation of the window beyond that point will be in jerks
(50 mm stages). WARNING
To obtain one-touch mode and/or manual mode operation (opening and closing) and the anti-pinch function, the
electronic system built into the motor must be correctly initialised.
Note:
A non-initialised system will function while the control switch is pressed, but the window will only travel a
maximum of 50 mm. Every time the switch is pressed the window will travel a similar distance until it reaches the
top stop.
