Hey Guys,
Trying to figure out if my 1995 Aurora has the OBD I or OBD II. And depending on which one it has, can someone tell me how to access them. In my 1998 STS I just push the On/Off button and Up Info button at the same time. Any input is appreciated. Thanks!!!!!!!!!!:thumbsup:

All vehicles use OBD II starting with 1996 and beyond. I dont know how to access your Diagnostic with your Rora, but sit tight, someone here does..

OBD2 connector
OBD1 computer

Ok, so if it is a OBD-1 is there a way to check the codes like I can on my STS w/ the OBD-II, or the only way with a handheld. Thanks

I think Cadillac is the only one that you can check DTC's onboard.
This reader is for OBDII but they have them for OBDI as well.
