Convenient Closing With Comfort Access; Indirect Anti-Trapping Protection; Panic Mode - BMW E90 Manual

Convenient Closing with Comfort Access

In connection with Comfort Access, the convenient closing function is triggered via the
driver's/passenger's outer door handle.
It is sufficient to touch the sensitive area of the outer door handle in order to trigger the
convenient closing function via the door handle. Convenient closing starts if the sensitive
area is touched for longer than 5 seconds. The identification transmitter must be within
an approx. 2 m radius of the vehicle.
Note: Touching the outer door handle corresponds to pressing the lock button
on the ID transmitter.

Indirect Anti-Trapping Protection

Essentially, the indirect anti-trapping function does not prevent an object being trapped
but rather it limits the trapping force to maximum 80 N. The power window motor is
reversed on exceeding this trapping force.
The footwell module and the Junction Box Electronics Control Module monitor the acti-
vated power window motors. The indirect anti-trapping function of the front windows is
activated by the footwell module. The indirect anti-trapping function of the rear windows
is activated by the Junction Box Electronics Control Module.
The indirect anti-trapping function in the E90 is based on the evaluation of the hall pulses
from the power window motors. The speed is derived from the Hall pulses of the power
window motors. Speed fluctuations within certain ranges trigger the indirect anti-trapping
function so that the windows are opened. Operation of the power window switches if
ineffective while the windows are opened.
The window can only be operated in jolts if no operable anti-trapping function is detected
as the result of defective Hall sensors. The power window (window regulator) is in emer-
gency mode and must be reinitialized.
Note: The initialization procedure is described in the Service Information.

Panic Mode

Panic mode is triggered by overpulling - releasing - overpulling (overpulling = pulling
beyond limit stop) the power window switches. It is necessary to release and overpull the
switch again in order to deactivate the anti-trapping protection function, which is still
active the first time the switch is overpulled.
Overpulling the power window switch the second time within 4 s closes the window with
maximum force.
Note: The indirect anti-trapping function is no longer active in this case. The
window closes at the maximum closing force and does not reverse.
