Does anybody have the definitions for the diagnostic codes (number of flashes) of an Australian NB8a? My manual is for an american spec. which has OBD2.

Good question - not sure, but codes are apparently in the manual link in the following post:

Thanks.
Gennerally, manufacturers added to their diagnostic code list for the new features of subsuquint modles, so the NA list is a good start.
I didn't have much luck with the manual links, but thanks anyway.

Sorry, Dragging out an old post....
I had just performed a diagnostic.. and the code is:
long long short
long long
long long short
long long
long long short
long long
long long short
So I believe the code is 20 and 21.
However, 20 and 21 wasn't mention on the code list.
Anyone can help?
Thanks

I read somewhere that the first long flash for each error is ignored, & this video
seems to back that up:
http://www.youtube.com/watch?v=cFqVJ4uaurwThat means your error codes are 10 & 11, BUT 11 is not on list either ?
My question is what do SGT (code 4) & PRC (code 25) stand for ?
Cheers
