DESCRIPTION AND OPERATION 86-5-11

Operation

Front windows
In order for the windows to operate the ignition switch must either be in position II, or in the off position with the ignition
switched-off timeout operational.

The front window switches provide ground signals to the BCU, which operates the windows.

One-touch down operation
The front windows will open completely with a single touch on the window down switch.

In order for the one-touch down to operate, the following conditions must exist:

l

Ignition switch in position II, or in the off position with the ignition switched-off time out operational.

l

Front window switch pressed for less than 0.4 second.

When the front window down switch is pressed for less than 0.4 second, the window opens completely. Pressing the
window up switch for less than 0.2 second stops the movement of the window. The BCU stops one-touch down
operation when it detects window stall current or after 10 seconds of window operation.

Depending on market, one-touch down operation can be fitted on both front windows or on the driver's side only.

Rear windows
In order for the windows to operate the ignition switch must either be in position II, or in the off position with the ignition
switched-off timeout operational.

The rear windows operate by the switch providing both power and ground to the window motor. Pressing one side of
the switch provides a power and earth path to the window motor that allows the window motor to operate in one
direction. Pressing the other side of the switch reverses the power and earth, which allows the window motor to
operate in the opposite direction.
