Comment: The note on page 46 regarding parasitic draw has a few grammatical error: "If multiple systems seem to be drawing amperage this is likely because one system is keeping the others awake on the network.". The previous sentence is missing a comma between the words "amperage" and "this". The second and main concern is about the last sentence in the note. "This diagnostics may isolating each system at a network spice pack or junction box" The subject matter of the note involves a diagnostic tip to identify a parasitic draw in a vehicle where network communication from a module that is not powering down is also keeping other modules from powering down. I believe it should read like this: "This diagnostic strategy may involve isolating each system at a network splice pack or junction box."

Comment: There should be an image of a fuel tank that has an expansion area above the filler pipe entry point. In place of the image is just text reading "defaultimage.tif" I can only assume whomever edited this page, made a slight error when leveling a file as a .gif.

Comment: I think the entire module of 305i Vehicle Networks is better suited to be relabeled and moved to the 301 section right after 301e Multiplexing and Networking instead of in 305 under accessories. Most other year modules are structured as how something works and then the following is how to diagnose it. The 305i describes the diagnosis of the 301e modules.
