Please note that in many of the references provided, the SAE naming
methods are not followed. This may be due to manufacturers not
following the SAE protocols when providing acronyms and abbreviations,
or because they are common usage. Whenever possible, most automotive
engineers and technical information writers and providers familiarize
themselves with SAE specifications J831 and J1930 for electric/electronic
terms, SAE J604 for engines, SAE J1145 for emissions, J830 for fuel
injection, J139 for ignition, J387 for lighting and J1213/1 for
networking/multiplexing.
