OBC Diag Codes

Wed Apr 13, 2005 1:21 pm

I'm sorry I have to ask this, but I'm getting NO joy on the E36 forums....
Does anyone know what the OBC diag codes are for and where I can find out what they mean???
Thanks!
It's for my E36 320i BTW....

not exactly sure what you mean, but this may help

Thanks Datourer.... I looked over that page before. It tells you how to access the diag codes, but not what they mean.
I've basically unlocked my OBC, entered test 15 which comes up with a bunch of diag codes in the format XX YY ### E#... eg 01 20 255 E3.
What I really need to know is what those diag codes refer to and what the codes I got off mine mean...
Do they tie in with the fault codes that would be generated if there was a problem with the car?
HEEELLLLLPPP!!!
