I don't know if this will help or not but there's a posting on the
Pentax Fora on K-3 debug mode.
https://www.pentaxforums.com/forums/172-pentax-k-3/273233-pentax-k-3-debug-menu-fyi.html
I'll tell you two things, firstly, be careful you could brick the
camera, secondly, when my K-5II was behaving err. badly, I found the
debug mode for that camera and enabled it, (it's different than the K-3
is all I remember), and without a manual it was singularly unhelpful.
Heck for all I could tell it would have been singularly unhelpful if I
had a repair manual.
Good luck no matter what you do.

For the K3 boffins:
I have been given a K3ii body. It was apparently "sprayed" by a wave
at the coast. Unfortunately the mirror stays down (I can move it up
manually so it is not stuck) & AF doesn't work with a screw drive or
HSM lens. If I select LV, the screen is black because the mirror is
down. Because of the mirror problem, the shutter won't fire. All other
functions seem to be OK. I can make any adjustmets in the menus & can
view images already on an SD card. I reset the camera to defaults
which didn't help. The camera still has the original firmware.
