The best thing I can suggest is that you download the 05 Service manual. The BCM unit is complex and you really need the level of guidance that the manual contains. I only have Acrobat reader and can't copy the pages out. ( I just have to get the full crobat soon busy playing on the mo, WOW just checked the price of the full ACrobat NOW I know why I don't have it, Rip off!) The nissan site to get it is.
After the programs are installed, you open the service manual in acrobat reader (just as you normally would), make note of the page(s) that you want to capture (info is located on the bottom of the page) then choose file>print (but you're not actually printing). When the next screen appears, choose the cutepdfwriter from the printer name drop down menu and enter the page number you want to capture under the "print range" section. Then a "save as" option will appear, and you can save the page(s) as a new file. You will end up with an exact copy, illustrations and all.
