Great tool to have
This has definitely saved me so much time on the vehicles I work on, especially when checking computer data lines for shorts or communication issues between modules. I hook my lab scope to it and it is easy to use

Works well for troubleshooting CANBus problems
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.

Works great.
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.
