Function using power window operating switch
Operation or activation of the driver power window switch group (S20/1) cannot be influenced by other control switch.
An activation or an already active function from another switch is terminated if a new request for the relevant window is received from the driver power window switch group (S20/1).
The sequence is reversed if an obstruction is detected. If reversing is already active, it is not interrupted. If the driver power window switch group (S20/1) is reactuated after completion of the reversing operation, the corresponding setting is then activated.
Hierarchy of control commands:
A power window control command with high priority is carried out if a power window function with low priority is currently active. This applies only if the function requirements for the high-priority conditions are satisfied.
A control command with low priority cannot affect a current power window function with higher priority.
If the low-priority control command continues to exist after the function with higher priority is complete, then the control command is ignored. The neutral position of the lower priority control command must first be detected before the corresponding function is activated.
Priority 1: Central locking via SVMCM alarm
Triggering an SVMCM alarm leads to interruption of all active functions with low priority. The vehicle is "locked" according to the data stored in the special vehicle multifunction control module (SVMCM) (N26/9).
Priority 2: Driver power window switch group (S20/1)
When power window control commands are given using the driver side power window switch group (S20/1), the first switch actuation causes the abort of any active lower priority function. The second switch actuation results in activation of the function.
Priority 3 : All PW control switches except the driver power window switch group (S20/1)
For control command via other control switches except the driver power window switch group (S20/1), the first switch actuation leads to interruption of an already active function with low priority.
The second switch actuation results in activation of the function. Each switch has access only to the power window motor assigned to it.
Priority 4: Central closing and central opening via infrared signal
Priority 5: Automatic window closing or opening via recirculated air button
The above function sequences are carried out by the respective door control modules.
