No longitudinal drive functions, cradle will not drive in or out.

No Longitudinal Drive Functions, Cradle will not Drive in or out. Also appears none of the buttons work on either side on the front of the magnet enclosure. See long description. The system is a 1.5T Excite which was just upgraded from 11.0 M3 to 11.0 M4. After the upgrade, there are no longitudinal drive functions. The cradle will not drive in or out. It appears that none of the other buttons on the magnet enclosure function as well, on either side. The FE ran the “Magnet Enclosure Button Test” found under Functional Checks in the Service Docs. Looks like none of the buttons are seen. Couple of notes; there are no errors in the log and the TPS reset is successful. Also, if they lower the table, the cradle will retract as normal. So it would appear that there is some longitudinal function, just not with the button pads. Replaced the SRI2 twice and no difference. Also disconnected one magnet enclosure button pad at a time to isolate a bad button pad but no difference.
