P1389, 2004 Jeep Grand Cherokee 4.7

In this video, I'm rambling on about things I'm trying out regarding a code P1389 which is no voltage from the Automatic Shut Down (ASD) relay to the PCM. The Jeep has twice in less than 2 years just shut down on me with no warning, hesitation or anything. Just engine quits. I'm able to crank back up fine and run fine. More commonly involved, with bad computers in Chrysler made cars, is it will show warning signs like clicking relays and blowing fuses to running rough and crank but no start, but this one is different. So an option I'm trying is cleaning the terminals with CRC Electrical Cleaner and hope this helps. If not then I'm looking at a new or used or refurbished computer replacement.
