I don’t think it happened with forescan.
After I turned off the car…. Over night… something changed. It was after installing the key200.1.

I thought maybe I hit something after I took out the ac unit to access the wiring for the plug and play

If you had to pull the A/C control panel that would explain the communication errors that I didn’t get time to investigate when I answered earlier today about ground 301. Pull it again and check that it is plugged in securely. I think that is Module A. On Ford’s PTS website it was listed as Front Controls Interface Module A. There is no reference in the workshop manual or the wiring diagram to a FCIM, but it may be the HVAC and audio controls, which is the module you pulled out.

Sounds like an amp didn’t sleep and drained your battery. Everything goes wonky with low voltage. Try putting on a charger.

Thank you to all of you trying to help me!

I reran everything yesterday. I did change my ground for the front amp… but not the back amp. Will try that now.

Check grounds, fuses and then ever wire connections you touched. Pretty sure you got a loose factory connector some place.

So…. Thanks to you guys, I figured it out.

I followed the install steps from another thread, and in those steps, it directed me to connect the factory amp ground and my new 8g ground for the back amp (kicker 500.1) and put inside the ground terminal in amp.

I took the factory ground and taped off and only put the new 8g ground in Kicker 500.1 and I got my power back and all sensors went back to normal.

im still having some error codes when I run FORScan tho… not sure if that’s normal or not… but my car isn’t alerting me of anything anymore.
