The Simply Auto OBD II Fault Reader helps you quickly diagnose and clear engine fault codes, keeping your vehicle safe and well maintained. With an easy-to-read backlit LCD display, it clearly explains why your check engine light is on. It works with OBD II–compliant petrol vehicles from 1996 onwards and diesel vehicles from 2004 onwards, including CAN systems. The tool checks MIL status, emission readiness, and can retrieve the vehicle VIN on supported models. It plugs directly into the vehicle’s OBD port, so no batteries or software are required. Compact and portable, it’s ideal for cars, SUVs, vans, and 4x4s, helping you save time and money by identifying issues before visiting a garage.
