Thank you.
Maybe so. The setec system seems to work elsewhere.
Also, just a safe way to close the big battery contacts to access through the Chademo port would be great and valuable.
Since the poster V2x posted his experience using on a USA 2014 Leaf, I doubt it is a software problem in this country causing the problem. Something isn't play well together but if a 2014 Leaf in the USA can I would be surprised that a later one cannot. While not in the ranger of impossibility, I would say it very improbably that the Leaf has changed to prevent it.
Sorry for disappearing for a bit. I just closed on selling my house, thus completing my divorce (FREEDOM!) and simultaneously having life jump me. Things are gradually settling down here.
BTW, I can think of another solution that so pretty because it involves modifying the vehicle, but should work. Hijack the connection between the LBC and the rest of the car (á la Dala [pun intended]) so you can omit/manipulate any information we necessary to keep it from freaking out, and replace the high voltage cable from the battery module to the PDM with your own Y cable, add relays and then an extra connector for your usage.
hehe, I failed to notice the second page of responses on this post.
Just to note that depending upon how far Nissan went with this sabotage effort, there could be unintended consequences of firmware locale mismatch between components on the same CAN bus. To return to my previous rant, this is the type of bullshit that should be illegal, but for our shitty political system and atmosphere here.
I don't think it's possible. It's securely programmed in its microprocessor and can't be read. And if you could read it, you're looking at compiled C code (speculating this) assembly language and it's essentially impossible to get it to a readable source form and make meaningful changes. If you mean cut off the top and read the die, sure, it's possible. But this isn't in the scope of what you can do yourself.
There are many companies who will
In the chademo port there are two pin that if connected (shorted) , tell to the car that the connector is on, and the car cannot move. The car refuse to go in D, B or R if these pins are connected each other.
Thank you very much for your insight and comments. We are very interested in pursuing access to that big battery which we will then put to a solar charge controller to change it down to 48 V to run the normal 48 V inverters for houses etc..
Don’t be scared you can do it please😎
Maybe do the simplest possible on modifying the canbus communication just to keep the battery contacts engaged
This is my personal thought, but I'll have to play with it to verify that the issue is sabatoge when it sees the battery going down instead of up. As you're probably aware, when you plug in the J1772 L1 or L2 charger, the charging hardware in the PDM takes responsibility for doing the charging -- the shop manual goes into pretty descent detail on this process. But for CHAdeMO (and I presume CSS on other cars) the quick charger is responsible for all of that.
