Starting a thread to collect this information.

CMU board with labels,

Wow what a great experience you've had--thanks for sharing the story, and thank goodness you went out prepared with extension cords and level I, even if not needed. You are definitely exploring new territory of these packs and cars, and every little bit helps understand what they do and how they wor...

Thank you Simon that is very informative. As far as i know, nobody over here has a real MUT that will perform these tasks such as your Diagbox tool. Are you able to call up individual data list items or does it just give the entire list? For example items 56 and 57 deal with the eprom. ref: CMU DATA...

That's amazing--we have to figure out what you did to get those results.

What is the age and condition of the 12V Auxillary (Starter) Battery--is it the original OEM that came with the car?

Input and output pin configuration of BMU connector: A is [1-26], and B is [1-22] 31-52 connector C-109 1 Auxiliary battery power source 2 EV-ECU control power source 3 BMU earth 6 CAN interface (high) 7 CAN interface (low) 8 K-LINE 12 Main battery cooling fan relay 13 Main battery cooling fan PWM s...

It appears that Rupert printed out the lower 256 words of the eprom, but the datasheet indicates room for 512--i wonder what was in the upper block, if it were blank or had some data? In his arduino code, ADW needs to be 9 instead of 8, in order to read out the upper block. Looking at the data, i th...

... Because if he had misidentified the modules then replacing the wrong CMU would not have fixed the problem with invalid voltages being reported...yet CMU_08 is now reporting valid voltages again after being replaced. That suggests to me that his layout is correct. Of course i could be wrong abou...
