PCM help

Hello I have a scanner I bought from murray's for odb II. The scanner worked good for a couple months than when I would try to connect it to the pcm it would just power off. Thought it was the scanner so I had it replaced, still does the same thing. Do you think my pcm is messed up or the programming port? Thanks Jason

Dunno, but first thing I'd check it to be sure you have power to the DLC port, maybe a fuse is blown?

Yep, check the cigarette lighter fuse. It feeds the DLC. Some scanners need this power.

Thanks guys. That was it, must of popped it with my Ipod. I was getting scared thinking it was something serious because I just had the whole car apart last winter
