Electric vent window, function - GF67.39-P-1000GR
MODEL 166.8 up to model year 2016
Function requirements, general
- No overvoltage or undervoltage
- Circuit 15R ON or run-on time active (up to t = 5 minutes after circuit 15R OFF and front door still not open)
The electronic ignition lock control unit transmits the terminal status terminal 15 via the interior CAN.
The left front door control unit captures the status of the left front door and sends this via the interior CAN.
The right front door control unit captures the status of the right front door and sends this via the interior CAN.
Electric pop-out windows in general
The function enables the rear pop-out windows, between the vehicle's C and D-pillars, to be opened and closed.
Convenience features are available for opening or closing by opening or closing the pop-out windows from a central control point. The convenience features are described in detail in the separate convenience feature (CF) function.
The electric pop-out windows are operated using the pop-out window switch.
The priority of possible functions depends on their requirement. A command with higher priority is performed if a function with lower priority is currently active. A lower priority function is interrupted first and is accomplished only after the second valid request. If a command with lower priority is still present after completion of an operation request with higher priority, the former command is ignored. It is first necessary for the controls to recognize non-actuation of the lower priority request before the corresponding function can be activated. Priority sequence:
- Vent window switch
- Actuation via diagnostic tester
- Comfort opening/closing via central locking (CL)
- Convenience opening/closing via recirculated air function
To perform a manual function, the pop-out window switch has to be pressed and held.
To start an automatic function it is sufficient to momentarily actuate beyond the catch point.
The electric pop-out window function comprises the following subfunctions:
- Function sequence for manual opening and closing
- Function sequence for automatic opening and closing
- Function sequence for automatic reserving function
Function sequence for manual opening and closing
The pop-out window switch must be pressed and held at the first catch point or beyond in the "Open" or "Close" direction. Actuation lasts as long as the corresponding request is made, but not longer than the actuation time of t = 5 s stored in the rear control unit.
The left front door control unit reads in the status of the pop-out window switch directly. The left front door control unit sends the request over the interior CAN to the rear control unit. The rear control unit then directly actuates the left pop-out window motor and the right pop-out window motor simultaneously.
The automatic reversing function is inactive during the manual adjustment of the pop-out windows.
Function sequence for automatic opening and closing
The corresponding pop-out window switch must be actuated just beyond the first catch point in the "Open" or "Close" direction, and then released.
The remaining function sequence corresponds to that of manual opening and closing. Actuation of the pop-out window motors is automatically ended after expiration of the actuation time of t = 5 s stored in the rear control unit.
The automatic reversing function is active during automatic raising. Automatic opening can be interrupted by pressing the pop-out window switch in the "Open" direction. If the pop-out window switch is then pressed in the "Open" direction, the pop-out window motors are actuated again accordingly.
Automatic closing is not interrupted by pressing the pop-out window switch towards "Close".
If the rear control unit detects a defective obstruction sensor strip, then only manual closing is possible.
Function sequence for automatic reserving function
Pinching is detected by the left pop-out window anti-pinch protection contact strip and the right pop-out window anti-pinch protection strip.
The anti-pinch protection contact strips are integrated in the window seals and they are read in directly by the rear control unit. When pinching is detected, the respective pop-out window is automatically reversed with the actuation time of t = 5 s stored in the rear control unit.
