Great diagnostic tool
Plug and play, used to diagnose missing ground or power during diagnostic fault. With this tool I was able to identify the data was missing not the power or ground. Definitely helps identify pending issues

CAN Diagnosis
I’ve been using it to diagnose the CAN on my 2009 Chrysler Aspen Hybrid. It works very well.

So affordable, add this to your advanced diag tool kit.
Nice addition to the advanced tool box. On a lower speed bus, I can see the LEDs blinking with data activity. May not see on higher speed but that’s where a scope comes in.
