Possible causes, elimination, notes

NOTE:
  • The DME control module signals a fault directly to the Tiptronic control module via a data lead (CAN bus).
  • The throttle plate angle can be tested with the Porsche System Tester 2 (Actual values/Throttle plate angle).
  1. Read out the fault memory of the DME control module and remedy the fault according to the DME test plan.
  2. Check wiring from Tiptronic control module connector pin 85 (or 86) to DME control module connector pin 85 (or 86) for open circuit, short to ground and short to B+.
