D6T throwing codes like candy

I have a 2011 D6T sn ZJB00289. Out of nowhere it started spitting codes like mad. Machine still running fine, but we shut down for lack knowing what is happening.
Machine is new to us so we are unfamiliar with how to read the display or what it is telling us.

I used to know how to post video, but feature seems to have disappeared.
Using the dash menu service list, this is what comes up.
We bought the machine with 6602 hrs, has 6629 now

E1154(2) 2 6629 6629 x
E583(1) 1 6629 6629 X
5-7(1) 1 5856 5856 X
E192(3) 1 6603 6603 -
590-9(3) 1 6303 6303 -
596-9(3) 1 6303 6303 -
490-3(2) 2 6099 6467 -
274-4(1) 1 6628 6628 -
880-3(1) 1 6035 6035 -
1078-3(1) 1 6035 6035 -
1079-3(1) 1 6035 6035 -
2458-2(1) 4 6594 6628 -
2458-13(1) 1 6626 6626 -


Any thoughts on all this?
And if someone knows how to upload a small vid, let me know.

Thx everyone,

You should be able to scroll through the fault codes from your dash, at least I have been able to on the D6T's here. As each codes scrolls, look for the SERV CODE icon to come up with each code. That will indicate an active code. If there is no SERV CODE on a fault code, it is a stored code in the computer. You need to find out which ones are active to narrow your problem down. The ones I have been on are a 2 part code......it will flash like a 030, 036,113, etc...…..and the next part that flashes goes with the previous. One of these insanely experienced CAT guys can guide you through the codes better than I can and they have been of great help to me.

What's the current hour meter reading..? I'd imagine somewhere around 6600-odd

A bit of explanation about the Codes.

• Those with E in front are Events, all the others are Diagnostic Codes.
• The number in brackets directly after the Event/Code is the Level (1, 2, or 3) of the Event/Code.
• The next number is the number of times the Event/Code actually occured.
• The two 4-digit numbers are the hourmeter readings when the first and last Event/Code occured. If there was only a single occurence of an Event/Code then both 4-digit numbers will be the same.
• No idea about the "X".

E1154 relates to the DPF filter (Low inlet pressure)
E583 is high differential pressure in the air filter - IMO probably related to the DPF filter.
E192 is related to a steering system but I can't find it in D6T ZJB-prefix. Please double-check.

First up, did you buy this machine from a dealer with some sort of warranty..? Because if so IMHO your first call ought to be to them.

The "X" on the display is for a Diagnostic Code/Event that is currently Active. All the others with the "-" are only Logged.

Re-read your OP with the machine hours. The only Codes/Events that have been generated during your ownership are the following. I've re-organized them into chronological order so it can be easily seen which one came first: -

E192(3) 1 6603 6603 - I wouldn't worry too much about this one TBH, at least for now.
2458-13(1) 1 6626 6626 - DPF #1 Differential Pressure Sensor Requires Calibration (see attachment)
274-4(1) 1 6628 6628 - Atmospheric Pressure Sensor short to ground.
E1154(2) 2 6629 6629 x - Low DPF #1 intake pressure
E583(1) 1 6629 6629 X - high differential pressure in the air filter

The rest of the list you posted are logged and really ought to be erased using ET at some convenient point in time.

Never having worked on a TIER 4 engine I'm in uncharted terrirtory here, but it sounds like Cat ET might be an essential for this one, even if it's just to erase Logged Codes. With the E1154 Event having been the first one registered time-wise I'd be tempted to perform the troubleshooting procedure for that first and see where it gets you. From what I can see most of the procedure you could do yourself. Also check the harness connections to the atmospheric pressure sensor while you're at it.

Looking at your video also the 5-7 Diagnostic Code may well be a key to it. I initially discounted it because it was so long ago, but it has an X which means it's Active, and it has been Active for almost 800 operating hours since 5856 smu. It is for Cylinder #5 injector not responding properly. "The ECM has determined that the mechanical wear for the injector is out of specification. The ECM continues to energize the injector solenoid."

Wondering out loud if a half-way bad injector might be enough over 800 hours to clog a DPF enough to generate Event Codes..? Does the tractor smoke at all under any particular load conditions..?

Could it have had an injector change at some point and either the wrong E-Trim file was uploaded or even still using the old file in the ECM..?

Hey Nige, you are way over my head here.
Seller is sending CAT tech tomorrow hopefully.
Along with everything you have identified, the engine status screen shows blank readings for Engine oil pressure, Boost pressure, and DPF inlet pressure I think. Manual regen not allowed.

I am not going to venture a guess here. Will let Toromont figure it out.

Thanks for your help!


Ken

I think that plan is likely the best one. However a few suggestions: -

• Ask the Tormont guy to download a Product Status Report before he touches anything and either email it to you or get it on a memory stick. This is a pdf document that will list (among other things) all the Diagnostic Codes/Events that are visible in the video of the cab monitor screen.
  
• By rights he should give you two copies of the PSR - "before" and "after". In other words the one I referred to above and the second as a final step before he leaves the machine.
• Once everything is completed and there are no more Active Codes, ask him to erase everything from the monitor. That way you will know that anything appearing after that is new. (You have the PSR from #1 above as confirmation of what was there before)
  
• Point out to him the #5 fuel injector fault because it's the oldest Active Code and ask for it to be troubleshot. As I said before I believe that there is a possibility that a dodgy injector from way back could be the root cause for what you are seeing now.

All of this BS is why these machines will never end up as farm machines and will probably be scraped ! There probably will never be Cats from the modern era end up as collectibles such as twenty's.

Update,

Cat was out finally today(Techs at this time of year are run off their feet)

We have 5 issues.
1) injector 5 has intermittent misfire. Almost certainly a broken wire at or inside the injector body. They have repair harnesses they carry with them because this is a common problem
2) No reading on engine oil pressure, atmospheric pressure, or boost pressure. Since those 3 sensors are very closely located, he figures broken wire inside harness near there.
3) no DPF inlet pressure. There is a letter published talking about condensation collecting inside the small tube feeding the sensor. There is a kit available to fix this known problem.
4) DPF sensor not reading. Likely a bad sensor.

Tech figured best to haul the machine in to the dealer, that is what they are going to do. They have to remove all the DPF gear to get at the engine. Figures at least a week downtime! Crap!

Update

In the end, the problem was an atmospheric pressure sensor. The computer uses the value out of that sensor to calibrate the other sensors, so when it fails, it causes a cascade of failures down the line.

They also replaced injector #5. They has sporadic issues, and decided to replace it in the end. Set the valves while inside.

Took 2 weeks. and the bill was likely staggering. Dealer covered it. Thank you Thank you Thank you...

Nice of the service documentation to state that - NOT ...........!!
File away in memory banks for "Ron" - later on ..........
