OBDII Breakout Box

Have had a lot of highspeed can bus issues lately on cars. (Been a tech for 23 years, specifically with electrical and computer diagnostics). Plugging this into the OBD2 port on a car gives me quick verification of battery power supplies at connector, grounds and CAN bus activity. The ability to tap into the banana connectors while a scan tool is plugged in also is fantastic for reading waveforms with an oscilloscope. Also checking overall CAN bus resistance unpowered using the banana plug taps makes diag much faster and more convenient than trying to GENTLY probe the OBD2 connector itself which sometimes are buried in the depths of a dashboard. Fantastic tool and well worth the money for quick preliminary and some more advanced testing.

That break out box works great for me.

Excelente producto . Lo recomiendo 100 %

So far I have only used this to charge a scan tool thru the ODB II port since someone lost the charger for it. Overall it is nice, but the port that the scan tool connects to isn't deep enough. It is very easy for the scanner to come disconnected. Besides that flaw it is good.

Great quality

If you are learning auto-electrical systems this device is simple and can help you see the OBD signals as they are operational. If you have an oscilloscope you can see even more.

It told me everything was working properly. So my rear caliper sticking must be causing my abs, tcs, and awd system to shut down for safety. 2012 G37xs

This breakout box sure makes bus can and K-line diagnostics easier, it gives a good place to run a oscilloscope while still using a scan tool, a must for a diag technician.
