Window Anti-Trap Detection: Notes
Each pressure guard at the top edge of each doorframe consists of two contact strips that close when subjected to pressure. This provides anti-trap for the full travel of the window.
When the contact strips close, the window will reverse direction. The contact strip does not require that the anti-trap feature be initialized prior to operation.
The finger guard has a resistance of 1.2 KOhm and it is monitored for open circuits. Faults with the anti-trap system require that the window switch be held to close the window.
The example shown represents the driver's door window control and monitoring carried out by the Driver's Door Switchblock Module (PM- FT/ SB).
The passenger door window is controlled and monitored by the Passenger door module (PM-BT) and the rear door windows are both controlled and monitored by the General Module.
