  • Do you have a list of which channel is what? As in, if I wanted to know battery voltage (or any of the other things you said this is capable of providing) what channel would it be? If you have the list, or know where to find it and could share, I would love to have this knowledge! Thank you.

  • I’m looking for the dtc list too!!! It doesn’t matter that I can do this if I don’t know what it means lol. I’ve been looking all over the innardnests, can only for b5 and C4. No c5 or b6 which (might?) be the same? Also I get a 23 on the left, and 11 on the right display, in between c89, c1. C1 displays 0 on the left & 00 on the right which I think means no dtc present if it’s the same as a B5?
