BMW General Module 5 (E46, E83, E85, E52) Window Anti-Trapping Strip

Anti-trapping protection
Anti-trapping strips are fitted in the upper area of all door window frames on the Saloon, Touring and Coupe. A strip consists of 2 contact strips moulded in plastic which provide an electrically conductive connection when pressure is applied.

If pressure is applied to the finger-trap protection strip while closing the window, the closing function is interrupted and the window is driven in open direction for approx. 1 - 2 seconds.
The finger-trap protection function is NOT active when the switch is overpressed (one-touch function but permanently pressed).
When strip is not compressed it should measure 3K Ohms +/-5%. When the strip is compressed it should measure less than 1 K Ohms.
On the models E46 Convertible and Compact (up to 09/2003), E52 Z8 and E85 Z4, no anti-trapping strips are fitted. Due to statutory requirements, the one-touch function for closing windows is therefore only available on the driver's door.
Integrated anti-trapping protection On the E46 Convertible and Compact (as of 09/2003) and E83, the anti-trapping protection is integrated in the individual power-window motors.

Important
Following repair work on individual power-window motors, standardization is required to activate the anti-trapping protection.

Standardization
Standardization runs when the corresponding window is opened completely first of all. The window is then closed by means of sustained actuation of the corresponding power window switch in stage 2. When the end position is reached, the switch must be kept pressed in switch stage 2 for approx. 1 more second.
