Onboard Diagnostic codes

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.

Did they just keep using the NA codes?

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:

That 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
