Hello. How do I program ECM after the replacement? i installed a new ECM. I programmed it with SPS but can't turn the engine on. The anti-theft light disappeared but still can't turn on the engine. in SPS i did programming and replacement of ECM. Does anybody have any step-by-step instructions of SPS how to fix this problem and turn on the engine? It's Chevrolet Volt 2012 model. Thanks in advance. It shows error P0633-00 in the ECM and HPCM

What did you ever find out on this. I'm in the same boat except I ordered a pre-programmed ECM from FS1. I did the key cycling by pressing the start button with my foot off the break. I also got the security light to clear but was unable to get the engine to start or move from the high voltage batter. All dealers in my area will only program an ECM they install and it has to be in the car.
