Possible causes, elimination, notes

Fault effect:
Reduced driving program.

NOTE: The multi-function switch (MFS) can be tested with the Porsche System Tester 2 (Input signals/Multi-function switch).

1. Test the MFS with the tester. To do this, shift through all selector lever positions in steps and check whether the position display in the instrument cluster and the display on the tester agree.

NOTE: As the tester display appears after a delay due to the functional principle of the unit, do not shift through the positions too quickly.

2. Check MFS with wiring.
To do this, pull off the Tiptronic control module connector and test the MFS for continuity according to the table.







3. Check MFS without wiring.
To do this, disconnect the MFS connector and test the MFS for continuity according to the table.







4. Check wiring from the Tiptronic control module connector pins 8, 9, 36 or 37 to the MFS connector pins B, D, A or C for continuity, short to ground and short to B+.
5. Check adjustment of selector lever cable.
