I can't get my Datamaster program to synch with my PCM anymore. I've got an AKM cable that I bought a good while ago. This isn't a PC problem either, I can hook up to my bud's 93 Auto car with no problem. I looked at the schematic in my service manual and it's pretty basic, I've checked and I am getting the 5VDC on the correct pin. The schematic shows a couple of "black boxes", one of them being the DERM module, there also appears to be a connection to the ABS system, which isn't working on my car right now because my I don't have the ABS connector for my Moser.

Any ideas?
