I have a 2014 Civic Si Sedan that has a new Smart PCU and Push Button. The car will not turn on to ACC, any ideas?

Based on the wiring diagram, the Immobilizer/Smart PCU sends a signal to the subrelay which then should power up ACC.

I want to say this is a programming issue but not sure how you can program without ACC.

When I push the button it just beeps, no power. If I bypass the subrelay and force the power downstream, everything powers up, I just need it to come from the push button.

Any help would be greatly appreciated.
