So I'm chasing the no start/no bus problem on the newly acquired 2000 Durango. I have bus bias and the bus is not shorted (although the resistance doesn't match the web site I found, but maybe it changed at some point). Anyway, my PCM has both 12v sources and is providing both 5v outputs, BUT the ASR isn't switching. I have continuity between the relay and the PCM, but never get a ground. I am assuming that any time the PCM is powered up, the ASR feed should be grounded. Can anybody confirm this? Does anybody have a spare 2000 PCM for a 5.9?
