Turn signals not working properly after testing with AlfaOBD

I have a very odd situation going on with my rear brake/turn lights. I was testing all the lights on the truck with AlfaOBD to make sure they all work after I made some changes to settings. Now my engine light is on and it's throwing codes for each of the 4 turn lights, front and back. Here's all the current symptoms:

- All 4 turn lamp control codes are active.
- Turning the turn lights on with the blinker switch goes into rapid flash mode like it's detecting a bulb that's out. Front turn signals and side mirror light turn signals all work, rears do not.
- Hazard light switch does not flash them rapidly, but only the same lights as above work.

Now, with AlfaOBD commands, here is what works/doesn't work:
- Both front turn signals work.
- Rear left stop/turn light and rear right stop/turn light both work.
- Rear left turn light and rear right turn light both work.
- Rear left parking lights command works, but rear right parking lights command does not (same bulb as stop light, which does work)

Anyone got any ideas for what I can check?
 
Jgouldski: did you have a bulb go out that you replaced?
Did you change out the incandescent bulbs for LEDs?
You mentioned "changed some settings " were those light related? Did you change those back to what they were previously before you changed them? If so did the lights go back to working as they should.

No bulbs out, and none were replaced or changed. Yes, went a little hog-wild scrolling through the AlfaOBD settings. Wanted to try out some settings, but didn't keep a good enough record of what was changed. I've been re-going through it today and slowly getting things back to normal, but still having issues with the turn signals.
 
Just restore the backup file you saved before making changes...

Or review the log file you created by using read system ID, then saving to google drive...
