This is how I troubleshot my system and fixed mine.

Read the ssp to understand how the system works.
Yellow means overinflated
Yellow and green = leaking under inflated
This is on top of my head, it's been a long time.

Thank you.
Mine starts with yellow+green=blinking
then yellow constant

I got to the value on the fault side and was able to disconnect from reservoir but how do I disconnect the pipe from the value?

tt1234

also thank you for the note on tire, I am aware of the tire and time to replace will do once the suspension issues are resolved

I think I got it to unscrew but not able to remove, do I need to cut the end of tube to get it out?

The bit in the last photo is just the nut that holds the line on, you don't have to swap that part! Just the brass piece you unscrewed from it. That piece you have taken off looks fairly corroded and old, I wouldn't be surprised if that is your issue. Keep in mind, if you lose air from the strut after reinstalling those pieces, use the soapy water test to make sure you have put it on tightly enough, that larger piece in particular is difficult to get on tight enough since it has nothing good to grab onto.

problem didn't travel with valve it remained same and on rear passenger side.

Okay, that means it is most likely the shock itself, assuming the soapy water test came back without any warning signs. Rear shocks on these rarely fail, so you may want to consider a used one, since new ones are very expensive. It still could be a valve block issue, any chance you can listen to the shock and hear air escaping? If it is totally bottomed out in less than 30 minutes, there is a decent chance you could hear the air escaping.

That is what I would expect comparing a shock that had lost it's air to one that was properly inflated, nothing unusual about it!
