KAP 140 Issues

[Godzillou]

Hello,
Today, my autopilot Bendix KAP140 (Installed on a C172 Skyhawk + G1000) got an issue:
The pft (pre-flight -test) is ok + tone but it displays 5 digit (dash) instead of pressure.

I try to push baro button, an turn knob, but it seem to "freeze" and I can't enter any digits.

For information : AP engages when AP pushbutton is pressed and I can set a VS for example)
A technician enter in diag mode ( via RS232 and terminal), but he wasn't be able to solve the problem. ( No fault code)
Have you ever seen that ?
Thanks a lot.

(Sorry for my poor english , bur i'm french)
