I found the wires for the SSO-/SSO+ of drive module #2 of the Right Arm outer bogies were in positions 4 and 5 of the connector that plugs into the drive module P1 connector. They should be in positions 3 and 4. This prevented the PSE from coming back to the VME crate and showing valid on the GUI. I moved the pins to positions 3 and 4, the PSE signal comes back to the VME crate.
