I would expect DTC131 to set in the PCM if the BCA measured voltage and the BPCM voltage over UART do not agree in the situation you're describing. If you were to try rewiring the BPCM to measure all 27 modules between J1-1 and J1-32 then you would expect to see BPCM DTC219 when the total pack voltage does not agree with the max module voltage * 26. I'm planning to remove the BPCM from my truck as I convert to a modern lithium pack. I think its easier to provide the few signals that the PCM requires to be happy than it is to provide the many fake signals that the BPCM requires to think that I still have a lead pack.

Today's Topics:   1. Signal voltage to BPCM ([email removed])
Question for the group. If I were to add a 27th battery to my pack, there is obviously no signal wire to the computer. Total pack voltage would rise by 12 volts to 324 volts, but the total sensor wire voltage would still be 312 volts.
Would this be a conflict to the BPCM?Without getting into a long detailed reason for this question right now,I'm converting to LiFePo4 cells, and if there was no conflict it would be much easier with the pre-assembled modules I have purchased.Thanks,Kevin McMullin_______________________________________________

I'm building my lithium packs to 13 volt 60 AH. I have to limit charge voltage to each of the 4 parallel packs that make up a module to 3.6v. I looked into removing the BPCM but I would like to keep everything it controls intact.  Happy Connecting. Sent from my Sprint Samsung Galaxy S® 5 -------- Original message --------
