GENERIC
An example of a trouble code
p0400
All power train codes start
with p
= power
the next digit is a
0 this
indicates it is generic and is used on all makes
the number
400 indicates
an egr problem (egr=exhaust gas recirculation)
the two
00 in
this tc are just gap fillers and will
be used in further software development .
Again
p for
power
but this time the
1 indicates
manufacture specific and is only used on this make
and the last 3 digits
125 relate
to air system in effect the 1
is the air system and 25
is a particular section
or part of the induction or inlet tract
Below you will see an extract of
OBD2 trouble code lists taken from gm.com i cant post the link because
it is password protected .
OBD2 is the american equivalent
of the european EOBD, but is far more advanced (and
dont i know it)
