I have cleaned battery cables, checked sensors, un-plugged and re-plugged everything I can think of, battery is fine tried two freshly charged ones, and still the Atuo Shut Down relay is buzzing or cycling. Can't hook a scanner to it because the ASD Relay connects and dis-connects the scanner. I am just thinking the Computer is trash. Anybody want to trade two 4.7 computers for a 5.2 computer? I have a PCM out of a 2000 4.7 and a PCM out of a 2002. Both Durango XLT's. I will trade for one good PCM out of a 98 or 99 Durango that works. Any kind of help here is much needed!!!
