There is nothing wrong with the SEU:
The SEU was configured for 3-Axis mode. It's now
set to SPIN mode and all sensors apperar to be OK.

The INSTRUMENTATION Power was Off, so no
valid pressure readings..

EPU and LIU were also turned off in the meantime.

Instrumentation was briefly turned on, there
was no loss in Helium high pressure.

This must be a faulty reading.. on P3-T they
all say closed/off. Clearly they did not opened,
otherwise with the current spin rate they would
fly away..

The LIU does not need to be turned On for pressure reading.
This is just done by the "Instrumentation Power".
