Power window synchronization, function - GF72.29-P-4003S

MODEL 215, 220 

Synchronization  links the position recognition  value in the associated control module with the actual position of the window.

The following control modules must be synchronized:

• Left front door control module (N69/1)
• Right front door control module (N69/2)

Only on model 220:

• Left rear door control module (N69/3)
• Right rear door control module (N69/4)

Only on model 215:

• Rear control module (N22/6)

Synchronization is required following desychronization  .

If the window is not synchronized the control module has no information on the side window position and in which direction the power window motors (M10/3, M10/4, M10/5, M10/6)  should be turned to close the window. For this reason synchronization is a prerequisite for the power window one-touch up/down feature  .

Synchronizing 

Position window in question with power window switch  to upper block position and continue to actuate switch. The control module then sets the counter for position recognition to zero when it recognizes lock-up of the motor for min. 0.3 s. The window is then synchronized, i.e., the control module can now switch off the motor before reaching the mechanical stop when opening and closing the window.

Resychronization 

Resynchronization is accomplished when an error occurs in the position recognition, e.g. the position counter status is negative.
