OBD2 scanner and battery tester

The KW681 combines a check-engine code reader with a 6 V and 12 V battery alternator load tester. It reads live O2 sensor data, freeze-frame data and on-board monitor results. The tool clears codes, resets monitors and retrieves VIN, CID and CVN information. It suits DIY owners and technicians who want one device for diagnostics and battery health.

Works on 1996 and newer OBDII and CAN vehicles

Coverage includes most domestic and import gasoline or diesel cars, SUVs and light trucks in the USA. The tester handles 100 to 2000 CCA batteries of flooded, AGM flat-plate, AGM spiral or gel types. It also performs cranking, charging, alternator and starter system tests. Vehicles outside this range or voltage class are not supported.

681 model with TFT colour screen

The unit features a large TFT colour display and hot keys for one-click I/M readiness and battery waveform views. A red-yellow-green indicator shows vehicle status at a glance. Live sensor data and voltage appear in graphing format for playback. Buyers needing wireless connectivity or advanced bi-directional controls should look elsewhere.

Questions about this item

Should I pick the 6V or 12V testing mode for my vehicle?

The KW681 tests both 6V and 12V batteries from 100 to 2000 CCA. Select 12V for most cars, SUVs and light trucks; choose 6V only for motorcycles, classic cars or other 6V systems.

What does the 100-2000 CCA range mean when I test my battery?

It covers virtually every passenger-vehicle starter battery. The tester will report state of health, voltage under load and cranking performance for any battery rated between 100 and 2000 cold-cranking amps.

Does the OBDII/CAN interface limit which 1996-and-newer vehicles I can diagnose?

The scanner works on most 1996+ domestic and import gasoline or diesel vehicles that use standard OBDII or CAN protocols, covering passenger cars, SUVs and light trucks in the USA market.
