immo system malfunction on Jeep Liberty 03 3.7L v6

[IDEALDAN]

Hi mates, ideas needed please

Immo light is ON on this jeep liberty 2003 3.7L V6, Now I've Pin and reprogrammed keys, immo light offed and returned after a about 40 seconds. PCM has no communication on diagnostics but other modules do. I checked the 5 circuits to SKIM, 4 circuits (B+, IGN SW and 2 GNDs) all ok But the remaining circuit (PCI BUS) blinks when testing with Test Lamp with ignition ON
IS THIS PROPER?
Please help with suggestions.
I'll be thankful

try to jump the yellow/violet wire directly to the pcm its the same color PIN 30 and see if the immo light goes off... if not you have to see if pcm have no fault or the antenna check how it blinks with and without program key just to make sure that the antenna its ok.
