Honda 17-Pin to OBD2 16-Pin Adapter Cable

This adapter connects the older 17-pin diagnostic connector used on Honda vehicles to a current-generation 16-pin OBD2 diagnostic tool. It is a passive adapter — it adapts the connector and routes the useful pins through, so a modern scanner can read an older vehicle without any electronics in the line.

Built for daily workshop use, the cable stays flexible over a cold-rated temperature range, so winter-morning under-dash reaches do not crack the jacket. The 17-pin format covers the pre-standard Honda era; if your bench sees a mix of old and new Hondas, one of these in the drawer saves the improvisation.

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 Honda years does the 17-pin fit?
The 17-pin socket covers Honda’s pre-standard diagnostic era (roughly mid-1990s and earlier, market-dependent). Check the socket shape against the product photo before ordering.

Will every scan-tool function work?
The adapter passes the shared pins; system coverage is decided by the vehicle and your tool, as with every passive adapter.
