I have been chasing leaks for hours and used gallons of bubble mix LOL I absolutly cannot for the life of me find any leaks ANYWHERE but some leaks around the wheel valves. To me, they don't seem significant enough to produce the rapid drop off in pressure on the control side when the system...

So playing with this a bit more, mine behaves as you say. When I energise control but NOT supply, the control lines eventually get to a point where the pressure stabalizes, and the QRVs stop dumping. However, when I do a "Check and Hold" which sends pressure first and then holds control, the...

On your video, if you send the shot of air and then let go, you are able to observe your tire pressure and the pressure in the control lines stays stable. On my truck, the pressure in the control lines does not stay stable. It is always dropping. I do have some slight leaks around my wheel...

If you energize the control solenoid but DO NOT give it a shot of air, what is supposed to happen? On my truck, as soon as you energize the control solenoid, the pressure as reported by the PCU transducer slowly rises until the tires begin to deflate out the QRVs... Is that normal? I suspect it...

Agreed, on a working truck (mine) the ECU switch status always reflects the physical status of the switch no matter what operating mode. @ckouba In addition to what @Ronmar suggests above, From the Dana Manual troubleshooting a Pressure Sensor code 31 (which I know we didn't have but the...

Yes, switch being unplugged make no difference to the behavior. To clarify what I mentioned in my previous post, the Test Tool reports the switch as closed at any and all times the system is at rest, whether the switch is plugged in or not. The instant the system tries to operate in any...

The pressure switch on the wet tank. Even when unplugged, the ECU reported its status as closed. This is my thought as well. Any time the system was trying to inflate, the Pressure switch would suddenly report "OPEN" to the ECU and would remain that way till we canceled the test. So what it...

An additional thing to add. When we connected with the Dana diagnostic tool the unit would stop the cycling, and we were able to get it to inflate and deflate. This makes me think the solenoids are good(and they ohmed out good) However what was very strange was that as soon as the system was...

Actually, I zoomed in and you can kinda see it here. pretty good contact patch.

Actually it worked amazing! Yeah its hard to tell in the sand but those were down at 20psi. Its really noticeable the squish on pavement, but not so much in the sand. The CTIS complains if you go over like 12 miles an hour in the sand mode, so I tried cross country which is 35 psi I believe and...

Cruised to the coast to test CTIS sand mode.

Yeah I am going to go to Harbor Garbage tomorrow and buy a regulator.. I got a little impatient last night and hooked it up to the shop air as-is and while no hoses blew off, there were some creaks and groans, so I hope I didn't do any damage...

Thanks for all the helpful info, that manual controller looks pretty sweet! Good job on that. that being said, I do have the Dana Diagnostic Tool which has an option for test and hold (among other things) that will allow for in-depth troubleshooting. This is why I want to run the truck off the...

Hey all. Has anyone had experience hooking their LMTV to shop air so that they can troubleshoot air issues without the engine running? I tried hooking up to the front service gladhand, but the system didn’t take much air. I looked at the pneumatic schematic in the TM and I think maybe that’s...

Does anyone know of a Memorial Day parade near Portland, OR that has MVs in it? Thought it would be fun to roll in one with my LMTV.

Great farm truck.

Looks like it went for only $1,237 ? Did you win it?

Care to elaborate on this for those of us newcomers who are not up to speed. I am a new MV owner as well as a new member of an mvpa affiliated club and hadn’t heard that the parent organization was problematic in this regard.

Pays better than a WO3 with a hand receipt, so not surprised.

Need to do this job myself, interested to see how it goes for you.
