Well I was able to answer my own question, woke up this AM thinking about this Damn TPmS/RDC error and the random low power to the RDC.
Using my test light with the from fuse panel lowered and testing the 5 amp fuse I observed the same pulsing and low voltage….gave the wires a few tugs and pulls and boom constant 14 v to the RDC unit…I used INPA and verified I could start to see the tire’s report in so now I know I need to find where it’s loose and make the repair
