M35a3 CTIS questions

[Al Capone]

So I got this truck and it had been sitting up for few years . Lots of dirt dobber nests all over it and everywhere . lol anyway some tires were flat. Started removing one by one and replacing orings . Prior to this I got CTIS to somewhat operate once . I heard it going thru system check of tires . Now after I have swapped some tires out it does not do anything . Code comes up saying it has a flat which it does not. My question is did I need to install the wheel Assy onto or time it exactly correct for tire to get air ? I did not think about this till after ?

Do you have any pictures of the wheels as they are now? Are all six of the CTIS wheel valves installed and piped in? Are any of the wheels leaking now?

There is a section in the A3 TM that troubleshoots the CTIS. Maybe the pressure sensor in the air manifold is messed up.

Yes they are all plumbed in on all wheels . I have two wheels with slow leaks still . But takes a week or more to leak and they only go to about 20 pds
