redundant serial comm lines between all the modules.
Richard was asking what the most common codes are, U codes, comminication, this is going to be funny in 5g full out, anyway, that last video I posted, is exactly as I feel right now, time for winter to go away.

If IGBT's did not exist, the elecrtric could not exist, that was a question on test. What is a IGBT and what does it do, what is its function. I wrote, you cant see that, it is too fast even for the scope half arse time set. It is the heart of the BCMS/BMS system. Very fast switching, and somehow, I feel I am letting you all down, cuz I am not learning it quick enough. Trust, I am trying hard, just need patience to assimilate. :cool:

I also do need down time, and sometimes that means shutting my brain off, listening to archie bunker old vids actually helps, brings me back to old neighborhood, and yeah. Especially now, with my sister becoming an almost full time job in it's inherent, this is a passion, and I am going forward, can't wait to see how this thread/forum evolves, I most assuredly hope some ppl chime in, if they don't, proves that the logic is being ignored, and some may want to get it but are ashamed to ask.

Back when I was a kid in shop class, in 1990ish, teacher repeated something I already knew, but he hit it home with better panache than my dad.

I goes as follows\

"the only stupid question is the one that was not asked" I liked the simplicity of that curiosity.

As Billr aptly wrote somewhere here, this tech has been around for more than just a few decades. Getting the masses involved is not going to be easy, and right now, it is crunch time.

Forseable futur, lots of techs not getting the info, doing wrong diagnostics, costing huge waste of time, money and most of all, sending the client to other shops, when all you need to do is educate, take some time, read something, anything is better than nothing.

It took me a full two weeks in spare time to translate and assimlate to end up just asking myself, do I really need to know all that.

Yup, I do, cuz if I don't get the fundamentals forst, the rest is going to be hazy, and the rest of my diagnosis's will be erronous, end up in some one elses bay saying I don't know shyte from my left hand.

And that by BAT friends is what actually keeps me up at night, could I have done better and avoided my ego drop??

I am getting ahead of myself, but in same time, this is not only a job, it is a life. If teamwork is down, no amount of info will stick. As team leader, you need to be a glue of sorts, know the failures and heros of each character of said team. That takes time. Kind of like a family. When you got things properly roaded, oops, some french guy will get that, you know it is sailing, but oops, you hit a wall, no insurance company want to pays, not yet up to date on tech, buy tech, learn tech, still don't pay. Lent term vision here is amendment to having a strategy. If you don't learn you on borrowed time.

OK, end of it. I love coming here, and will never stop until they shut me or site down. ;)

@billr, today was start of 3rd module of 8. Today was measuring end resistance, what it means, and then scopes the variants in algorithm, counting when each command was given. Seeing the binary, in different systems, studying the tesla variant is difficult, but not impossible, just need time and patience.

Basically, today was about high speed can line, why we need to focus on that more than older "LIN" and other protocols.

Scoping was cool. Got to work on the bolt and compared to a old 2005 toy Prius.

It was funny to see similarity in the gen tech, but, mostly, impressive, is how the bolt is awake all the time on can line. Will only sleep once low cell disconnect. Still trying to figure that out. ;)

Today is my b day, and spent all day either in traffic, or on benches in montreal, my mind right now is not on writing, but yeah, I have a ton of stuff to populate the ev thread, I just need time, life gets in the way here, this site is not my job, it is merely a gabby hobby, any way, when I am here, I am not splitting heads at the local bar on my, want to have off day but cant, cuz I have responsibilities and wish I could travel back in time. .:cool::mad::bat:
