PM Systems - onscreen yaw damper switch goes to off

[GSalden]

Recently I updated all PM modules.

I now have the issue that when turning on the yaw damper switch it immediately goes to off...
This is with the engines running.

All suggestions are welcome.

Thanks,
Gerard

I have this same issue. I just have not tackled it yet.

This can be an IRS issue.
The IRS posittion when I set the airport in the CDU is slightly different than what the IRS shows.
This can be seen on the same CDU page too.

I snet a tickt to PM 4 days ago, but no reply yet  ( Last time I got an answer on a ticket after 5 months... )
