OBD1 & OBD2

[mr.utility at highstream.net (mr.utility@highstream.net)]

On Board Diagnostics is what it stands for, and it does refer to two different 
levels of complexity of those codes...  One thing though, I do not know if OBD 
I codes are the same as the later, I don't think so...  

On OBD II, each manufacturer uses a 4 digit numeric code to describe what is 
failing/wrong...  IE, 1610=ignition fault, cylinder 1 ignition fault, for 
example..  And no, that is not an actual code...  :-)

I think that OBD I is this way as well, but I am not sure...


HTH a bit,
