## Questions & Answers

**Q: How does this detect what protocol is being used on the can bus? all i see is a volt meter built into a simple breakout box?**
A: You have to use a lab scope to see anything regarding can bus. Here is a video from snap on tools thhttps://www.youtube.com/watch?v=DhX11X5ihws at may help you. If your using a volt meter all you will see is average voltage.

**Q: Dear friends, what are the main differences between this model and model obdii protocol detector & break out box diagnosed obd obd2 connector | warran**
A: Just looked at the obdII protocol detector & breakout box. Looks like the two are basically the same thing. I would say the otc piece is probably a little better quality piece, of course it costs a little more money. But the two will function pretty much the same way.

**Q: hi,can you shipping for australia? or not?**
A: Sorry, we only ship to USA Based addresses.

**Q: Does it come with Jumper wire in the kit?**
