DUOYI OBD2 Breakout Box Can Bus Breakout Box with LED Light Auto OBDII Protocol Detector 16-Pin OBD2 Breaker Box Automotive Electrical Diagnostic Tools Can Bus Analyzer with 35inch Cable

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.

Game changer for doing in car diagnostics when you cant get voltage readings to be consistent. So fast, so easy, and really clear instructions on what to do! Its a must have for any shop who is serious about repairing cars

Práctico bueno para ir comenzando tus diagnostico

That break out box works great for me.

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.

Great quality

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.

A well made product which can be used to connect the cars OBD2 socket when requiring to test externally without any damage to the host socket. It is colour coded with respective leds that illuminate when connected when testing which is a nice feature. It has a good length of cable that saves probing the cars OBD2 socket using four mm banana test leads when using a multimeter on the breakout.
