Pitch bump started, May 2022. Swap vg. That solved it for months.
Pilots report all good.
Swap airdata controller. (Back to original position)

after finding burned plug at RH lav:
#1 FD/AP will not capture altitude, but (sortof) will track altitude
#2 FD will not GA. RH GA will clear HDG select button, will not clear ALT select button. When RH GA is held down, RH Vbars will go to 0 pitch or lower, then disappear when G is released.

Collins manual that shows the difference between 590A-3H, and 590A3K
1.5.16 590A-3H Air Data Control
The 590A-3H Air Data Control supplies an analog error signal to the flight control system that is propor-
tional to altitude error. True airspeed, indicated airspeed, and altitude programming voltages are also gen-
erated for flight control system use. The altitude error gain may be programmed with true airspeed, indi-
cated airspeed, or altitude, or set at a fixed value. The 590A-3H also provides signals for altitude preselect,
vertical speed hold, indicated airspeed hold, and Mach hold. The 590A-3H is contained in a 318-ATR short,
low case and weighs 2.09 kg (4.6 pounds).
1.5.17 590A-3J/3J1 Air Data Control
The 590A-3J/3J1 Air Data Control supplies to the flight control system an analog error signal that is propor-
tional to altitude error. True airspeed, indicated airspeed, and altitude programming voltages are also gen-
erated for flight control system use. The altitude error gain may be programmed with true airspeed, indi-
cated airspeed, or altitude, or set at a fixed value. The unit is contained in a 3/8-ATR short, low case. The
590A-3J weighs 2.00 kg (4.4 pounds) maximum. The 590A-3J1 weighs only 1.5 kg (3.3 pounds).
