In some places this may be displayed in German language as, “Schutz Fahrzeug Diagnose” (SFD). Porsche Service Centers will find new PIWIS Tester functions, informational messages, and error messages pertaining to PVD when working on the affected vehicles. Affected vehicle control units (for example, the Gateway control unit or the DME control unit) may also store an active fault code B184C00, “Activation activated” as a normal function of PVD. These faults are for informational purposes and typically do not require diagnosis.
