I started a reverse engineering project on the MCM
My version is 1K000-PHM-305 and inside it is witen 1K000-PHM-060
Here is what i found here on Insightcentral
Yes 200ma of excess current per cell will spill over into the balance board load resistors when they go above 3.6v. But that would be quickly overwhelmed by say 50A regen down a hill if left unchecked and cell voltage would rise as they charge until possibly over the maximum. So as the battery...
This is a technical post. I'm documenting it here for posterity. Most people don't need to read this (but it's cool if you want to). This might prove useful for driving IMA system with lower pack voltages (where you can't just use a voltage divider to spoof the voltage on connector 'E'. ...
To your knowledge, is there any other part of the schematic that has already been done?
This PCB as at least 3 layers and the traces are very difficult to follow so the project will take long
I know some people have thought about the idea of one day creating a LIMCM. maybe it would be easier having the MCM schematic to make firmware for the PCBs we already have instead of making a circuit from scratch.
Unfortunately I am not the person able to code on a hitachi microcontroller, do we have a programmer who knows these microcontrollers here on insightcentral?

I added the G1 Honda Insight IMA Bay Wiring Pinout.pdf file, it is a file that must be renamed to .XLS it is a document made by @mudder
and that I added a line and 3 columns to serve as a legend for each input output. this Document allows you to know on which page of my plan to look for the pin you are looking for. a column indicates the type (analog, in, out, in/out) it also indicates when it's an output, whether it can force to GND or VCC and across which resistor when so.
