P12 slow read
Tried to do a read off a P12 today and could only get it to read when using "snail mode" , had to uncheck "fast read" to get it to read , thought that that had been fixed by now ?
Would go to about 532k to 556k and disengage and give read error , pulled "On Start" fuse and has factory radio , all doors were shut , head lights were off .
13 minutes to read , "theme song from Jeopardy playing" , one word comes to mind , starts with f and ends with k .

Yeah, I thought all P12's behaved nicely too.
What year was that vehicle?
Cheers,

Experienced this problem with a 2006 GMC Envoy recently as well. Each time it would get about 1/3 of the way through, the PCM would re-arm and it would fail.
Just on the trailblazer/envoy? That is odd.

I swear it has worked correctly before , wonder if something has been introduced through the last update ?
Don't remember the exact error wording but it was something to the effect that a interruption had occurred is why I pulled fuses and turned off stuff , BCM or ECM , neither .
