CMTOOL OBD2 Breakout Box with LED Light Indicator, Professional 16-Pin OBD Breakout Box, Automotive Electrical Diagnostic Test Tool, Portable Testing Tool

Works well for troubleshooting CANBus problems. It is an affordable item that allows you to easily attach your DVOM or scope to troubleshoot the onboard network. The onboard led lights have worked on the vehicles where I have used it. It has a pass-thru OBD port to attach your scan too on the side also.

Have not used product, but features easy to read outputs, and is pass through, so should work well for my needs.

Considered making one but could never do it for this price. Good value, well made.

It functions as advertised, plugged it into a can bus vehicle, turned the key on watched the network talking, then used a scope to watch the data, it's a lot better than climbing under the dash to measure voltage and resistance at the obd2 port etc. Easy to use, plug it in and do your test measurements.

Light weight and easily portable. Well made and works just as it should.

Clearly labeled, compatable with existing meter leads, LED's show power, ground, buss activity. My only complaint is, and I don't know if it applies to all of them, however I bought two and both (-) bus leds don't light up during buss activity. I think they didn"t install the LED backwards due to the fact the the negative buss communications is 0 VDC to (-)2.5 VDC.

ok

Just wanted to protect my pinouts on my odb2 port and this really worked well. All you need are some banana clip ends on both ends and you're testing your can bus.
