OBDII Problem
I suddenly cannot read the PCM. I just wrote some tune updates a few days ago and everything was working fine. Last night went out to make a change or 2 and could not read or write to the PCM.
HP Tuners wouldn't connect so I tried my trusty code reader and after about 30 seconds it gives me an error message. The message is "error".
I checked the fuse and is good. Cigar lighters is working and when I first plug in the code reader the lights flash but go off. Tuners has the green light with just the OBD2 plugged in, not the USB.
I have checked everything I know to check. You guys have any input. The car cranks and runs fine.

You might need to let it cycle about 10Xs to reset.
I had a similar event happen a few months back. It happened when I was continuously connecting to the OBDT II with my code reader getting some things done prior to a smog check. I think it was the *continuous* part
