hello my cat 966 is having a problem with regeneration system and works for 1 minute then stopped regen stutus is blocked can someone help me in this please?
A Serial Number would be a good start. That would enable information specific to your machine to be located. Are any Codes showing on the display.?
It seems it has reached proprietary lock down. It will require factory passwords to unlock and the issue must then be resolved
yes i have codes and i have the factory password but i cannot find where to reset cat company says it need to be connected to scanner to reset 1- DPF SOOT LOAD VERY HIGH E991-3 2- ARD FUEL PRESS #1 LOW E1052-2 3- REGEN CANNOT START SYSTEM FAULT E1301-1 REGEN STATUS LOCKED OUT
Needs dealer-level version of Cat ET to reset. This is done via a Communication Adapter connected between a laptop and the machine. Cannot be done from the machine display panel. Looking at those Codes I suspect you have more problems than simply requiring an emissions system reset.
A question based on your location. What type of diesel fuel are you using in this loader.?
diesel normal one,same uses since 2 years and i have one more error injector 5 connection
Injector not responding properly isn't that critical, engine will work fine. I think the root cause is ard#1 fuel pressure low, that can be caused by the pump in the fuel filter head not running. When it is powered it should be able to supply 1900kpa of pressure to the aftertreatment system. There's a test in ET or you can jump the relay and test if it runs and gives pressure. But you need Cat ET to unlock the E991-3 anyways.
OK, let me be more specific. Are you using Ultra-Low Sulphur diesel fuel.? In other words diesel with less than 15 parts per million of sulphur. That is what this engine requires because of the installed exhaust after-treatment system. If ULSD is not used the problem with the after-treatment hat you are having now is going to keep coming back at regular intervals.
honestly i dont know but i dont think it is sulphur diesel as this problem was before one year and the company changed the catalys that time
but my catalys is not same of your picture
the agent came snd cannot reset they mentioned due to injector error the ecu stopped the reset process
in scanner they clear all errors axcept the injector but in wheel loader i still can see the errors coming
In my opinion you should contact your fuel supplier and ask them. If the correct fuel is not used in this engine you will have continuous problems with the exhaust treatment system. Ask the fuel supplier straight out - “What is the sulphur content of this fuel.?” Post his answer back here.
E991 can be cleared with other codes active. But if the low fuel pressure problem isn't fixed that will come back and as soon as the soot load is too high due to the regen process not starting it will be back also. Injector not responding can sometimes be fixed by running the verification test a few times but if that doesn't help it needs to be replaced. Verification test needs to be run then also.
Like I said in few of replays from before, I've been struggling with same issues on a quite a few pieces of my machinery. The way how I solve it was deleting it. Bad quality fuel or fuel with high sulphur level will cause the issues before you blink. Don't try washing the filter with water! One of my guys did that, and it didn't end well.
we do wash with water and after that the machine started to run for one minute and stopped so what you do for this?
You start by making sure that you’re using the appropriate fuel........
Washing it with water will washout certain particles (I believe metal), and the filter will be useless after that. I don't think there is anything you can do to get it fixed now, except buying new filter. You can also check this https://machinery-tunes.com/caterpillar-dpf-egr-def-scr.html the photo of D6T is the one I sent them, that's my machine that they did and it has been running perfect ever since. In case you want to keep it with filters on, listen to the wise advice of the senior member above. Most important thing is to have good quality fuel.
The point I was trying to make - maybe not very well - is that unless the engine is fed with Ultra-Low Sulphur Diesel (less than 15ppm of sulphur) the problems with the after-treatment system will continue. ULSD is the only type of fuel on which these engines are designed to run in standard form. Based on the OP’s location I can find a lot of information regarding petrol (gasoline) quality but very little regarding regarding current diesel fuel standards in his country.
Based on what Per said above here is the troubleshooing procedure for the E1052 ARD Fuel Pressure Low Event. I undersand that you do not have Cat ET but at least it will give you some idea of what to look for.
my serial number is *cat0966kvbg01061*
Actually the Serial Number is PBG01061 but never mind. Please see the attached. Your engine S/N is MYE05421. From this article the sofware in the engine ECM should be updated to 470-9359 if it has not been updated already. there are a number of improvements in the new software, some of them involving the ARD system.
This article may also be of some use to you.
thank you nige so do you suggest to check all above before replacing the ECU to get red of the injector 5 problem? do you have the harness drawing for the injectors?
See the comment made by Per Eriksson in Post #15 on Page 1. The injector #5 Code is NOT the problem that is preventing the ECM being unlocked. (Please post the Code that you have for Injector #5 and I will see if I can find a Troubleshooting Procedure for it.) The problem preventing the ECM being unlocked is the E1052 ARD Event. I posted the procedure on how to diagnose that Event in Post #21 above. That is where you should direct your attention first. I will send an Electrical Schematic separately.
thank you i will go to location and check but what is the cat ET please
by the way when i change the fuel separator there is a power switch ti run the fuel pump manually and relese the air this one on top of filter case is working
my ard fuel error code is E1052-2 in the form you send to me comment ,,there are not enhanced troubleshooting indicatrs for this code
Correct, but there is a Troubleshooting Procedure listed on the document. Unfortunately it requires the use of Caterpillar's proprietary Electronic Technician (ET) software. So it appears as though you are going to have to get the Cat dealer involved again. Before they come to your machine send the document to them and tell them to make sure that the technician brings with him all the required Tooling that is listed in Table 2 on Pages 1 & 2, because I suspect that they will not know if you have an 11/16" or a 9/16" fitting on your machine.
And as Nige said, these engines need to run on low sulphur diesel, otherwise they'll have aftertreatment issues all the time.
yes i find out that the fuel is not low sulphur this is why the problem comes again all what am looking for now is to find a way to keep the enging running so i can shift the loader to an other location for better testing
I am not surprised by your answer. Unless the fuel used in your engine contains less than 15 parts per million of sulphur, known as ULSD, you will never overcome the problems with the aftertreatment system. The high sulphur levels in the fuel will cause excess soot to form in the exhaust filter system, and it will plug - causing the Diagnostic Events in the engine ECM that you are seeing now. The loader was originally built in November 2013. I imagine that you bought it used and it was probably imported from another country. That's where the fuel problem comes in. ULSD is commonly available in Europe, North America, and many other countries. Question: Does any fuel supplier in Oman sell ULSD..?
hrllo we buy it new one not used , i heared that in oman they started to manufactur ULSD now
I think your next move should be to speak to the fuel suppliers in your area and see who can supply ULSD. With that information you could produce a plan of what to do going forward.
Like I said multiple times, the solution for all his problems is CAT migration procedure. The non regulate countries are famous of lack of ultra low sulfur diesel. Just delete the filters, and get over with it.
thanks for the reply i asked the dealer to get over and they mentioned that i have to replace all the system and the cost is very high for the time been i just need a way to move the loader over the truck to shift the location as it works for one minutes and then engine stopped,before i clean the catalyses it was working for long time but after cleaning it get worst for running the engine for one minutes do you know how i can buy ET online i think it will be cheaper for me to buy rather than get the dealer and charge me a fortune for the visit
Even if you have the ET, like I do, you can't do the migration kit your self. Contact these guys https://machinery-tunes.com they can do it all, they work on all of my machines and I never had a single issue.
thank you i think this people is not located in my area
Dear All yesterday we change the ECM and all Errors gone and not back system now back to normal
final after cleaning the catalys we coul not reset the system due to injector 5 fault,that was coming from ecm and region was not able to start after replacing the ecm we do have the system working my concern is about the fan . that it ia not running unless if we remover the solinoid coil the dealer say we need to run the loader and chack the fan
