BMS trouble

I've been getting communication faults with my Elithion BMS.  The BMS plays several roles.  It is responsible for turning off the charger to avoid over-charge, disconnecting the load to avoid over-discharge, as well as doing the same to avoid any over-temperature conditions.  The faults originate in one or more of the cell monitoring boards attached to each cell.  By observing their blinking pattern I believe at least 2 are faulty, both of them are nearest the opening of the hood which makes me wonder if the elements are too much for the PCB.  In the front all that protects them is conformal coating and the hood.
