As you could see on my list, the LBC (BMS computer) is only connected to the EV CAN bus so capturing everything on that bus should show you everything that the battery computer tells to the VCM (or to other computers *via* the VCM). Concentrate on the point where the car starts up, that is when I expect that the battery gets validated as I explained in my last post.

I'm only capturing the EV CAN bus -- I'm interested in how the BMS is authenticated by the rest of the car, so that transaction must pass through the EV bus to get to the BMS. Unless it isn't done on the CAN bus at all, but that seems unlikely? _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
