Nice reference! Thanks, Matt.
If you look at the coding structure explained there, any of the codes
with a zero in the 2nd position (thousands digit) are standard across
all manufacturers and cars, so it's not just a GM reference. Not every
car is able to monitor every one of those, but a given code means the
same thing on any car it pops up on. OBD-II also standardized the
nomenclature for all the parts & controls. Seemed kinda draconian when
it came out nearly 20 years ago, but in retrospect, it's a good idea and
actually makes it easier for DIYers and small time shops to work on
modern vehicles (vs having to have a manufacturer specific reader for
each one.)
