Synchronization of power windows, function - GF72.29-P-4003Q

MODEL 209.3/4 

Normalization means teaching the upper window stop (zero point) into the

• left door control unit (N69/1),
• right door control unit (N69/2) and
• rear control unit (N22/6) (on model 209.3) or
• soft top mechanism control unit (N52) (on model 209.4).

Synchronizing 

Completely close window in question with left front power window switch (S20/1s1), right front power window switch (S20/1s2), left rear power window switch (S20/1s3), right rear power window switch (S20/1s4), passenger-side power window switch (S21/2), left rear power window switch (S21/3) or right rear power window switch (S21/4).

Continue to actuate left front power window switch (S20/1s1), right front power window switch (S20/1s2), left rear power window switch (S20/1s3), right rear power window switch (S20/1s4), passenger-side power window switch (S21/2), left rear power window switch (S21/3) or right rear power window switch (S21/4).

The left door control unit (N69/1), the right door control unit (N69/2) or the rear control unit (N22/6) (on model 209.3) or the soft top mechanism control unit (N52) (on model 209.4) sets the location counter for the Hall signals to zero if it recognizes a blockage of the left front power window motor (M10/3), the right front power window motor (M10/4), the left rear power window motor (M10/5) or the right rear power window motor (M10/6) for min. 0.3 s.

Normalization is prerequisite for:

• Automatic raising (only on windows in doors, except vehicles as of model year 09/YoM 08 with code (494) USA version or code (460) Canada version)
• Short stroke
• Switching off left front power window motor (M10/3), right front power window motor (M10/4), left rear power window motor (M10/5) or right rear power window motor (M10/6) before limit stop.
• Obstruction sensor

Renormalization 

Renormalization is accomplished automatically when there is an error in the position recognition, for example, if the position counter indicates a negative status.

Denormalization 

Denormalization occurs when:

• the position counter for the window obtains a value greater than the maximum window travel during automatic lowering,
• during automatic raising the window has reached a location counter status going beyond the negative zero tolerance or the stored zero point (except vehicles as of model year 09/AJ08 with code (494) USA version or code (460) Canada version).
• a supply voltage of less than 6.5 V is connected to circuit 30 for min. 60 s.
• one of the two Hall sensor signals from the left front power window motor (M10/3), right front power window motor (M10/4), left rear power window motor (M10/5) or right rear power window motor (M10/6) is erroneous for 12 armature rotations.

Normalization does not take place when the thermo-switch is actuated in the left front power window motor (M10/3), right front power window motor (M10/4), left rear power window motor (M10/5) or right rear power window motor (M10/6).
