Scanning for Chevy Bolt codes or live-data

Ok, can you zoom in on photo

Sheard right off.

Alot of these questions right now, need to be addressed.

I can only do one at a time.

The AC comp, hv main, was shorting, two on board charger modules later, the ev dumped, and at that speed, just plain butted the main shaft, picture is worth more than my sorry ass english.

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

Apparently, pag oil was the answer, I called bs on it, said no to second dc dc inverter. All along, the HV comp was the culprit.

Isolation code, system shut down

 

[nickb2]

So, when that happens, statagy is to localize. What is causing a full isolation mode?

 

[nickb2]

For warranty reasons, pag oil was a no fault way to go, but for sure, no one took the time to check after second isolation, shytdown.

Then it got to me. At that point, I said, we need education. And, yes, it went forward. https://www.youtube.com/watch?v=YR5ApYxkU-U

So if it is OBD2 still, then are the common codes now all like UXXXX?

Are PXXXX codes going to become uncommon?

Do you think if manufacturers are going to keep with OBD2 that the stardard will have to change / be expanded on? And if so how?

 

[nickb2]

Are PXXXX codes going to become uncommon?

Those will be common, but they have changed to a variant such as this example P0A0D which is HV system circuit high.

The codes are quite extensive to learn, the data in scanner is hallucinating, the data stream needs to be prioritized, probably saying that wrong, I mean you need to select what you need, if not, the amount of info can be a deterrent to finding a glitch.

I know this thread is in infancy stage, I will try hard to explain want I find.

We are starting to see more and more EV's at the shop, as some of those cases come in, I will update, but still don't have much experience with the day in and day out of it all yet, we are ALL on a learning curve up here. They are starting to roll in, warranty is out so it was just a question on when we have to make transition, we now, that time is here. I will happily try to answer or make some posts of the stuff I see.

This should be fun.

Since I am an advocate of elm dongles, I was surprised to see a software such as leaf spy and similar on market, there is a free version of the leaf spy. It has some cool stuff to see, such as battery balancing which is nice.

I downloaded it to my phone, I will try it on the leaf we have at school. I will have to see if my current dongle supports it, if not I will try to get one that is, that way I can also help others who don't access to a high en scanner. https://play.google.com/store/apps/details?id=com.Turbo3.Leaf_Spy_Lite

Do you think if manufacturers are going to keep with OBD2 that the standard will have to change / be expanded on? And if so how?

No news yet on other protocal, we are hoping lobbying will keep it open, but when you see what tesla is doing, you never know, it is fun to see competitions for hack tesla, a few guys from montreal won something lately, also a competition in vancouver went down, and while this may be a bit off topic, there was a trend for awhile where companies such a kia, toyota and some odd others had free open source info, don't try that today, all paying sites now.

As it evolves, we will be seeing more can buss sniffing and reverse engineering, we just need to give it time. For me, alot of what I read makes no sense, I just ain't that smart yet. But it is happening as we speak, and tweaking that will surely be right around the corner soon.

So maintaining a standard of safefty is going to be judicial here, may want to put in a few disclaimers/stickies such as back when with airbags.

Right now, with 5g, this is going to get real interesting real quick. For those interested, go lurk here for a bit, cool stuff to read and watch.

This is also blowing my mind, don't how that will hold up to our northern climate, but since they are testing that in Sweden, I have high hopes. https://www.theguardian.com/environ...ed-road-for-charging-vehicles-opens-in-sweden
