Just installed ironman FCP on my son's 2014 Luxury. Removed the airbags and put the washers under the bracket for the headlight leveling and I am still getting both Check Headlight System and Check BSM System. Is there something else I am missing? I have searched and searched and cant figure this out.

Can you pull some additional codes with Techstream or OBD Link?
The BSM (Blind Spot Monitoring) error is not something commonly seen.

Is your AFS light on too? Ever since my lift I had my AFS light has been on and have not been able to fix it.
It doesn't ever bother me, but it's there flashing.

FYI: AFS only existed on 10-13 models with HIDs.
Were any wiring harnesses pushed around or anything temporarily disconnected?
You would need a OBD reader/softare that can see extended Toyota/Lexus codes like OBD Fusion or Link to pull codes.

You mentioned Luxury so you have “two” rear height sensors that are used for the air bags and the headlight leveling

I did unplug both leveling sensors after install because I didnt have the washers and thought it might turn it off, but both warnings were already displayed and I hadnt disconnected them. Only other sensors disconnected were the ones going to front and rear shocks. I put washers under both passenger and driver side brackets. I used 7 washers on each bolt. It looks pretty level to me. I also tried removing the air sus fuses under hood and no change. Battery was disconnected while installing suspension and I have disconnected it after doing all of the washers etc.
If you can get some codes I can try to help further..
That BSM error is something else because that is totally separate system w/ECU and sensors in the extreme rear areas of the rear fenders. Black box below taillight. BSM wasn't offered until 2014

On that B1856 have you unplugged the second row LH airbag connections or at some time in the past?
I’m curious if original errors on dash stick around once the speed sensor wire is repaired

Ohhhhh I bet that had something to do with the airbag the dealer had to replace. Son just bought this about 3 months ago and had to go back within first week for airbag light and valley plate coolant leak. I ordered a new sensor wire should be here Friday.
Now I need to also figure out why the touchscreen/head unit turns on and off over and over. He apparently was just ignoring it because dealer wouldnt fix it.
