2005 equinox service vehicle soon

I just installed a Python 580 with a DB-ALL on a 2005 Chevy Equinox LT AWD. Everything works, but I am getting the Service Vehicle Soon Light when starting via Remote Start. My next plan is to start disconnection some of the connections to the BCM, but was hoping for some direction. I read another thread regarding the parking light connection, but that was for the (-) and I am using the (+), could this still be the issue? Here is my wiring schematic:

Well, that schematic is worthless at that size. I will try to upload the PDF to the web and give a link...

Do you have the light green keysense wire being energized during remote start?

No, I do not. That was on my short list of "Do I need this, or not?".

From the Equinox Owners Manual: (for clarification)

Think you need to hook-up the Keysense wire.

 KEYSENSE       LT. GREEN (-) (REQUIRED)         @ BCM, GRAY 24-PIN PLUG, PIN A8

Soldering is fun!

Thanks. I will give that a try.
