KONNWEI KW310 OBD2 Scanner — Engine Code Reader

The KONNWEI KW310 is a plug-and-play OBD2 diagnostic scanner that reads and clears engine fault codes on OBD2-equipped vehicles (1996 and newer).

When the check engine light comes on, plug the KW310 into the OBD2 port under your dash to see what the code means before you pay a shop to tell you. No batteries or apps required — it powers from the vehicle.
