CAN logs from aux DLC port

First off - I don't own a Volt. I am attempting to use the battery from a Volt in something totally different and I'd like to figure out the CAN messages that the Volt sends to the cell balance electronics while it's charging. I believe the information I want is only available on the HV side CAN bus, which is available on the aux DLC port. Does anyone have such a log they can share?

I'm in southern Wisconsin, so if you're within an hour or two I'd love to plug my CAN snooping gear into your Volt and get a log for myself.

I'm game, if 53204 is close enough.
I sent you a PM with my contact info. LMK!
Got. Will email in the next day or so.
Yes! Hellsop hooked me up and I got tons of nice logging done on all the CAN busses on his Volt. I have been working on the hardware side of things. I laid out a PCB for my battery controller last weekend and my heating and cooling components are finally here so I have more work to do.

Pretty much everything useful on the CAN is hacked. Voltages, current, temps, etc. Everything except the cell balancing commands, which I have on my list of things to do in August. The Volt battery is so well made that I'm beginning to think balancing nearly never takes place.
BTW the cider was excellent. I should road trip westward sometime and bring the bottles and your clipboard. It's been a month since I ran the ICE....
