A/C Diagnostic mode
 

Can anyone point me in the direction the A/C diagnosis documentation? I'm having some issues (no cold air), have checked relays / breakers and for codes via OBD2 with no luck so assume the gas has departed, but saw the below image in another thread and the system is only flashing three times (not the four it should) then flashing a "2s" code. I've been unable to work out what "2s" means.

I took the image from this thread https://www.ft86club.com/forums/showthread.php?t=101733 where it apparently came from the repair manual but my google search is letting me down.
