Seat Common Structure (SCS) Memory Function or Fore/Aft Adjustment Faults
If you receive customer reports in the above model vehicles that the Seat Common Structure (SCS) front seats have either a memory function fault or
moves fore/aft in short steps, the plug in the seat fore/aft adjustment motor (Figure 1) may have been connected incorrectly. This leads to a fault in the
Hall sensor and may cause the normalization settings of the seat fore/aft adjustment to be lost. To correct, raise the seat completely upwards, remove
plug and insert correctly (Figure 2).
Possible Complaints on the Driver Side:
-
Memory function of electric seat fore/aft adjustment not functioning
-
Seat fore/aft adjustment with easy entry/exit feature not functioning
-
Head restraint presetting (head restraint is set automatically in relation to the position of the fore/aft adjustment) not functioning
-
Seat fore/aft adjustment can only be adjusted for 2 seconds with the seat adjustment switch (seat can only be adjusted in longitudinal direction
