Someone in an other post is in contact with Modulegods and they think they can reprogram and completely eliminate the SKREEM module but they need a working set of parts to decode them. They need a keyfob, Skreem and PTCM. He can decode what needs to be reprogrammed in the PTCM to bypass the startup procedure.
( disable the SKREEM entirely ) anyone have a spare car with working parts. After a SKREEM failure we would need to send in only the PTCM to be reprogrammed at a cost of about $200
