2004 Mountaineer PATS issue?

Hi everyone,

It's been a fun few days in my garage. I started the weekend by replacing the front wheel bearings and hubs on my 2004 Mountaineer. When that job was done, I tried to start the vehicle to test drive it and found that the battery was dead. I tried to jump it and it cranked but wouldn't start, after trying it a few times, it stopped cranking all together. It's not a no-crank from the starter but rather no noise coming from the starter at all. All i hear is a click, sounding like a relay closing, from under the dash around the fuse panel. I then noticed that the red security light on the dash was flashing rapidly when I turned the key to the on position. After blinking rapidly for a while, it blinks a code. The code is 1:6 which I have read is 'Faulty link between PATS module and EECV. Go to dealer.'

I have checked all fuses and tested relays by giving them power and they all close. I don't believe it's a starter issue because of the security code but I will test it just to confirm. I'm lost as to where to turn next, but I know that the dealership has to be a last option because of finances. Is there a good way to diagnose the link between the PATS module and the EECV? I'm willing to dig into the electrical if I have to, but I just need to know where to start.

Thank you in advance for any suggestions you can offer.
