Porsche 19-Pin to OBD2 16-Pin Adapter Cable

This adapter connects Porsche vehicles fitted with the 19-pin round diagnostic socket to the 16-pin OBD2 connector used by current-generation diagnostic tools. Porsche ran its own round diagnostic socket through the pre-standard era; this is the bridge that lets the workshop’s existing OBD2-based tools reach those cars.

Working temperature is −30 to +80 °C and the connector and cable materials comply with the RoHS standard. As with the whole adapter family, it is passive: the connector changes, the pins route, and nothing else in the diagnostic chain is touched.

One honest scope note that runs across this whole family: a passive adapter changes the connector and routes the pins that the vehicle’s interface shares with OBD2 — it does not add protocols. Which systems a scan tool actually reads depends on the vehicle and the tool software, not on this cable.

FAQ

Which Porsches use the 19-pin socket?
The pre-standard era, market- and model-dependent; match the round-socket photo in the engine-bay or under-dash position before ordering.

Will a generic OBD2 scanner work?
Only with Porsche-module coverage. The adapter bridges the socket; the tool does the talking.
