Vlad:
I have looked thru the CD and can find no direct reference to anything called BEM. I suspect that I know where it may be, but my Russian version of the original Japanese manual translateed into Jingerish is rather confusing. The main headings which I suspect may relate to your area of interest are:

54A-CHASSIS ELECTRICAL
54B-SMART WIRING SYSTEM (SWS)<NOT USING SWS MONITOR>
54C-SMART WIRING SYSTEM (SWS)<USING SWS MONITOR>
54D-CONTROLLER AREA NETWORK (CAN)
55 -HEATER, AIR CONDITIONER AND VENTILATION
70 -COMPONENT LOCATIONS
80 -CONFIGURATION DIAGRAMS
90 -CIRCUIT DIAGRAMS


Each of these sections has umpty ump sub sections - far too many to list here. If you PM me, I can hopefully narrow the search field down to you area of interest.
