Thanks a ton , il stand by .

Is there anyone that can post a picture or help out, im going to try a few other things tomorrow but this part sure seems like the cause of the issue, would be nice to fix the easier things. Jay

Roger that , I found that , mines a little diff but same thing pretty much. I didn't see the CTIS one near it. And nothing in the manuals says anything about that part.

TM9-2320-272-23-1 page 257 looks like the thing I circled in red in the picture but Im going to look around and see if I can find the ones your talking about, update , I know what the low air pressure switch looks like, we had to change one on a friends truck. Im still not locating the CTIS one.

Also , when you drain the air tanks if you drain number one , it drains all the air out of the truck without turning the others?

Bump?

I have a new issue , I read the TM doghead posted. My CTIS was working on the trip home. I had a air problem and the truck wouldn't cut off building air at the correct PSI. I replaced the check valves and rebuilt the air dryer and fixed the issue 100%. Now when I crank my truck and its...
