Error Codes - How to fix them

[Changman927]

I've made a few modifications using the spreadsheet. Everything seems to be working fine, but I am seeing the following errors in Forscan. Not sure if I should be concerned:
Code: P05A2-Active Grille Air Shutter 'A' Control Circuit / Open
Code: U0131 - Lost Communication With Power Steering Control Module 'A'
Code: B1265 - Left Rear Turn Lamp Feedback
Code: B1444 - Left Rear Stop/Position Lamp Output
Code: B1533 - Headlamp Switch Module
Code: U0121 - Lost Communication With Anti-Lock Brake System (ABS) Control Module 'A'
Code: U0415 - Invalid Data Received From Anti-Lock Brake System (ABS) Control Module
Code: U0418 - Invalid Data Received from Brake System Control Module 'A'

These codes may have been there before I started updating things with Forscan, but in my nervousness did not notice them fully. Prior to Forscan I have changed the taillights, added hitch with brake/indicator adapter, added foglights, and interior lights. Not sure if disconnecting the originals caused some of these errors (I am not mechanically skilled at all, but followed YouTube and this forum for guidance). Should I be going to Ford to confess my sins, and ask for forgiveness? My truck seems to be operating just fine. The turn signals all work, power steering seems ok, no issues that I can feel while driving.

Did you clear codes after making forscan changes? If not, these are more than likely from whatever changes you made and just need to be cleared.
If any return, then I’d worry about potential looking into them depending on what the code is.

Here's how you clear codes with Forscan

(basically boils down to hitting the "Clear Codes" button - but here's a 4:01 video that says the same thing while taking 4:01 to do it)
