Dash fault codes

We are about 3 weeks away from breaking camp at our current RV park.  We have been here about 2 months.  In that time once every 1-2 weeks I have been starting the coach just to check systems for about 10 min.  No issues before today.

Today when I started it I show Check Engine/No Fuel and no air readings on the either front or rear.  Interesting thing is the engine runs fine/no issues.  Generator starts / runs fine no issues.  When we camped about about 2 months ago we had 3/4 fuel levels.  Did have to run Gen for about a day when power was out but was it. 

While it was running (had engine running for a good 10 min), even though front/rear air showed 0 I was able to level the coach no issues at all.  It came up on all 4 corners to Mid-ride levels.    When I shut it down, I tried the pocket doors a couple times and while a bit slower they opened and closed just fine.

Its after hours so I will call in FOT and/or MOT tomorrow.  We have a few weeks so no urgency tonight but need to get sorted out.

Any suggestions welcomed... 2014 IH45.

Thanks

Tom

With the dash you have you can find out what the error codes are.  Not at the coach so don't remember what button you have to push to get the screen up.  The screen when you get it will have all error codes it has ever had along with the date and time the error was recorded.

When you are running the engine are the other gauges working?

In your hose and cord compartment there is a switch that is marked something like reset RVC or something like that. That might reset the gauges

Found the following:
You can display this information whenever the Check Engine light come on by pressing Diag and activating the Engine Diagnostics Screen.

I pulled up the screen and the only fault it reports is code 96 Fuel level update  (added the error screen).  The generator starts and runs fine.  As I understand if there is less than 1/4 tank the Gen should not start. (all my previous coaches were that way).  As I mentioned we had 3/4 tank when moved here 2 months ago.  Nothing leaking underneath... at a loss here

On the home gauges the fuel needle is indeed at the bottom of gauge but Def is 3/4.  However the air gauge front/rear BOTH read 0 too.  I believe I do have air.  After running for 5-10 min I leveled the coach with no problem.  Pocket doors (air controlled) worked fine.  In the past its always come right up.  The HWH screen shows air on all corners too when level. 

I tired the reset in the wet bay.  No change.  I saw there the Silverleaf codes dont map directly too any Cummis codes but if you call Silverleaf they will give you the code mapping. 

Also down loaded the VMSpc software and manuals.  Going to install that in the morning and see if I can find a cable somewhere for my PC.  If I remember though, that should be reading same interface on the engine the dash screens is too. 

short of a solution here, I was going to call support tomorrow.  Coach seems drivable if I needed too.  I am not far from FOT/MOT..about 2 hours so that may be my solution if all else fails

Sounds like the module that takes the air pressure and fuel tank level has disconnect from the bus or had gone bad.

Need to look at drawing as to how it is wired

Not sure what you found out yet.

The VMSpc software software reads what is on the RV-C buss and put the information on a computer screen, just like your dash.

I did some searching and it looks like the Silverleaf TM-102 Module is the device that collect input from the fuel tank and air pressure sensors.  So either this device has died or it has lost it's connection with the RV-C buss.  I know there are modules around the coach and they have labels on them with their model number.  I have no idea where this one is located. First places I would look is in the water pump compartment, inverter, HWH compartment, and possible Aqua Hot compartment.

Had a call with MOT service folks.  In fact he said it sounds like the TM-102 is having some issues.    I did some checks on air system/brakes/etc.  All good.  HWH display shows the air 137, drops when I level, then comes back up.  I hear the pressure release / popoff valve on occasion while engine runs. 

Since the generator starts/runs no issues, he confirmed there has to be at least 1/4 fuel in the tank.  I havent physically located that module yet but since I am headed to MOT in a couple of weeks for a few other things, I will probably have it fixed then too.

As aside, I ordered a Bluefire for a back up to my dash/displays/instrumentation.  I had one before with my Tiffin.  It was great reading direct from the Cummins itself. 

Thanks again for pointing to that module

Just as a FYI your coach was 3 after mine. 6583  when I get back to my coach I will try to figure out where that module is located

Not sure why you feel the need to start the coach so often. It's really not good as the water/oil temp never gets hot enough to dissipate any moisture build up after you shut it off when it's only luke warm. And moisture in the engine crankcase means "RUST'.    If you start the engine, You 'should" be driving it after air pressure builds.

Actually it was a recommendation from MOT tech, which I admit in 30 years of having RVs and over 20 in DP i had never heard.  I really didnt put much stock in it to be honest.  We took delivery of this coach early April.  Since setting up camp at present I have probably only started it 2 times.  Once for tracking an air leak (another story/another thread) and this time because we as mentioned breaking camp in 2-3 weeks I am doing pre-system checks on everything now which turned out to be fortuitous in this case.

When I have stored my coaches in the past (we are FT now) I made a practice of taking it out of storage every 4-8 weeks and at least driving it around the storage facilities or taking it up and adding fuel. 

I hear what you are saying though.  Although again in all my years I have never had an engine related problem (dont jinx it now...) in the practices I have been doing. 

Thanks though for the feedback.

Thought I would close out this thread.  After talking with both FOT and MOT, and now at MOT for a small punchlist of maintenance stuff,  determined the TM102 module to be bad.  BTW the module is in the wet bay next to the manifold for all the plumbing just for reference.

I asked MOT if I could just order/swap it out myself and they told me it has to be programmed to my coach.  They are overnighting one from Silverleaf.  Should address all the issues with the dash gauges and check engine light

Thanks all for feedback and help.

Well...wonder of wonders...it was NOT the TM102 in the wet bay but actually the TM102X under the passenger air vents.  Thats the good news

As the tech told me these are programmed by "one guy" at Silverleaf.  They have to read him all the specs and then he programs the module for each coach.  (think I remember that was called a single point of failure in my working days...)

Hooked up...have Fuel and Front air but no back reading.  Now they are checking the rear sending unit itself too.  Tech "noticed" some green corrosion on the wire fittings under the dash.  Suspects condensation got in at some point.  I would guess that would have to be a LONG time ago (pre my owner ship of just a few months) to actually get to the point of noticeable corrosion build up. 

Hopefully getting to the core of the issues now.

There is software called Omniscope that you use to program these devices.  If you have the program file, all you have to do is download the file to the device. If the old device can still communicate you can upload the program from one device to another.

There are a number of other people besides the one at Silverleaf that can program those. I would bet there maybe someone at Foretravel that can do it.

Sending one last update...  I spent better part of 2-3 days this week really understanding this module and what "programming" it means working with the tech at MOT. 

The first module he received from SilverLeaf as a replacement turned out to be defective itself.  Since I had a scheduled departure date from MOT, tech called over to FOT who had (his words) a refurbished one in stock.  Opt'ed for that.

When he got, I guess it had come from a different coach or defaults were all set. 

I watched him go setting by setting in the Silverleaf and use his Omniscope off the link for feedback.  Amazing number of options and what they all do.

At the end of the day he was still befuddled by a couple of settings.  One was the fuel system that read full 200 gal no matter what (I knew I was only about 150 full).    I suggested as sort of a last resort to go over to another 2014 IH45 on their lot and go through/screen shot all those settings...thinking same year/basically same coach.  Turns out several screens on the setup looked different. 

A call to SL (another one) and they had him flip one setting in the accessories screen options which turned on and changed several other screens.  Now they all matched the other 2014 IH and everything fell into line.  All works as should now.

I immediately screen shotted all of the SL setup on my dash so if had to in the future, pretty sure I could reset/setup a new module  myself.

Moral of story ...highly recommend to anyone to go into the diagnostic/setup (hold the drive/scan buttons down for several seconds) and page through each screen taking pictures of all your settings.    Perhaps something everyone already knew/does but it was good learning for me.

I used to fly (PPL) and always had "steam gauges" in my planes.  Never had a glass display...kind of makes me wish sometimes had steam gauge dash default here too...Nah...this is still good!

Thanks for the update.  When I get back home I am going to get pictures of all screen settings.

This has also got me thinking about fuel gauge. When tank is full the most fuel it will show is 198 gallons.  As it gets low it seems to have a 40 gallon buffer.  When it shows that I have 60 gallons left I am lucky if I can get 100 gallons.
