Universal OBD2 Diagnostics Tool

The Jansicotek KW310 is a handheld scan tool that reads and erases engine fault codes on every OBDII-compliant petrol or diesel vehicle sold in the USA from 1996 onwards. It connects directly to the 16-pin port and powers up with the ignition, requiring no battery, app or separate power supply. The unit delivers live sensor data in digits and graphs, freeze-frame snapshots, oxygen-sensor tests, Mode 6 advanced monitor results and EVAP system leak tests. A dedicated One-Click Readiness Key gives an instant emissions-drive-cycle status check.

DIY owners and home mechanics

This scanner suits drivers who want to diagnose check-engine lights themselves and verify emissions readiness before a state inspection. It covers generic, manufacturer-specific and pending codes across all major OBDII protocols. Workshops that need bi-directional control, module programming, ABS or SRS coverage should look at a higher-tier tool, as the KW310 is limited to engine and emissions diagnostics.

1996-plus OBDII protocol coverage

The single specification that decides fitment is the vehicle model year: the tool communicates with every US-market car, SUV or light truck built from 1996 forward that follows the OBDII standard. If the target vehicle is older or uses a proprietary pre-OBDII connector, this unit will not connect.
