Are there any DTCs being thrown for the BECM related to the IMD, if so what are they and where can we find the factory workshop manual to read about this?
Where does this board reside--internal to the pack or external?
Is there a separate BMS board or is that the function of this board? Or put another way, what are all of the functions of this board?
In the nissan laef the 'IMD' function is done on a section of the LBC (BMS) board inside the pack.
In the mitsubishi miev an insulation and ground fault check function is done in a separate little box inside the pack, independent of the cell monitoring boards and the BMS box located under the rear seat.
Most of the EVSE units that i have seen have some sort of ground check and ground fault isolation check circuit that must pass or charging will not be allowed.
What do the 4 threaded mountings pads contact when the unit is bolted together--do they attach to vehicle chassis or to something else?
