Universal OBDII Diagnostic Tool

The Jansicotek KW310 reads and clears generic, manufacturer-specific and pending fault codes on all OBDII petrol and diesel vehicles from 1996 onwards. It supports full OBDII modes including live data graphs, freeze frame, oxygen sensor tests, Mode 6 advanced results and EVAP system leak testing. The patented one-click readiness key gives a quick emissions status check. No battery or external app is required for operation.

Powered Directly From Vehicle

The scanner draws its power from the car's OBDII port so there is no internal battery to charge or replace. Its compact 5.94 x 3.22 x 2.2 inch form factor keeps the cabin uncluttered during diagnostics. Because it operates without a companion app or wireless link, there is no additional radio-frequency load on the vehicle's electrical system. The Energy Star qualification reflects low standby consumption while connected.

Ready-To-Use Kit With Multilingual Interface

The package includes the KW310 unit and a printed user manual so the tool works immediately out of the box. An optimised software algorithm delivers menu navigation and code retrieval 2 to 3 times faster than basic scanners. The interface supports seven languages, letting technicians and owners read live parameters, freeze-frame snapshots and readiness monitors in their preferred language without downloading firmware.

Questions about this item

How do I install the KW310 and what step is often missed?

Plug the KW310 into the OBDII port, turn the ignition on, and wait for the main menu to appear. The step often missed is confirming the vehicle is a 1996 or newer model with an OBDII or CAN system before connecting.

What maintenance or replacement will the KW310 need later?

The KW310 has no internal battery and no consumable parts, so it requires no scheduled maintenance or component replacement during its service life.

What limit appears first when using the KW310 continuously on a vehicle?

The KW310 draws power from the vehicle's OBDII port, so sustained use is limited by the vehicle's battery condition and the ignition remaining in the on position.
