My girlfriends truck got a "Service Engine Soon" light and I'm trying to check the code. I went outside thinking GM OBD1 use a paper clip to jump the pins and read the code. No such luck its an OBD2 connector. Apparently this was a transition period for GM and they used OBD1 computers with OBD2 plugs.

I tried a generic OBD2 reader and wasn't able to pull any information. Has anyone dealt this this before? How can I read the code?

Those era GM's with a 16 pin OBD DLC dont communicate with an OBD protocol.
You have to have a scan tool with the proper software to get codes from these vehicles.
