So, what would I need to get for the Bolt?

My perception is that OBD2 standards don't necessarily apply. Is there a standard for connector and data that is fairly universal for EVs, or are we back to the pre-OBD days when all manufacturers had unique?

To get live data on a bolt, kia, need a scanner that sees the on board charging module. al ev I have seen up until now, have obd codes. And only those are associated to body, ucomm bus can disruption.

Last week, was able to see at least the 300 or so cells in live data. It was fun to see that without the need of hacking some shyte for something that is supoesed standard.

If, you really look closely, the shaft butted. The Imev motor shorted, armature had amp on, thing hit asphalt. After that, here is the result.

Perfectly working, but no go. It took three hours to come to the concision.

Something mechanically went wrong. So, this is the type of scenarist, this thread should evoke.

When the scope was on, data loss on low cell, car went into limp mode, no bios recovery, replace unit shorting the bus, In this case, it was AC comp. Shared same HV, same low 5 v follow thru path.

Even a seasoned tech, if I may say, such as I would have missed that one. So, be aware,

3000 or more dollar after, second motor shorted out. All the time, it was the ac comp.

So, when »I say, first. understand the system. Google is your freind at this pointépint, :eek:

I'm not understanding much in that reply #12. Does it refer to the photo in reply #11? What is in that photo? The assembly on the left looks like what I would expect for a traction motor, but the one in the center is too "flat" and is incomplete. Is that center one from a hybrid? does it mate up with the one on the left somehow? The unit on the right looks like it has a pulley for a serp belt??? Is that the A/C compressor you are talking about, engine-driven in a hybrid?

I have no clued what a "shaft butted" is, and see no sign that something "hit asphalt".

How did the A/C compressor take out a traction motor?

What Autel P/N should I look for? And yes, I am expecting "sticker shock" on the price!
