Working on a 2013 Cadillac ATS with push start type ignition. It appears that it has a timer on the ignition so that if you leave it in "run" with the engine off it will shut off after a minute or two.
I have been trying to do "read entire" and grab the ECM and TCM files, but it times out before I can get it all. I have to grab one controller at a time.
I'm a bit worried that if I try to flash it will cut power mid flash and brick.
Any suggestions?
