Went to write a calibration using the latest beta............. no different then usual. It timed out on the write....... and now the ECM does not show up. Says unlicensed vehicle.
I've got a Tech 2, I hooked that up, the PCM/ECM is not present. Tried pulling battery, checked fuses............. IT'S DEAD.
Never had this issue before, what do I do? This is my womans car, need this fixed by tomorrow night........
*freaking out*......... BIGTIME
