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
