I have a D5m 6GN with a 819 fo2 serv code and the quad gauges don't work .Need help?
Here's the Troubleshooting Procedure. Worst case scenario the quad guage unit may have failed but do all the harness tests first before officially declaring it dead. Note that if the procedure indicates that the module is dead it recommends repeating all the tests a 2nd time just to make sure.
Thanks Nige all my test points to the control gp 126-9401.
Sorry to hear that. I hope you did all the tests a second time as recommended in the troubleshooting procedure before declaring the unit dead. Be careful about the Part Number for the quad gauge. There appear to be various Part Numbers depending on whether the machine has a cab or not, and also what Serial Number range the tractor falls into. The options are: - 6GN0001-1532 cab 6GN1533-2126 cab 6GN2127-Up cab 6GN00001-1148 open ROPS 6GN-1149-1632 open ROPS 6GN-1533-2126 open ROPS 6GN2127-Up open ROPS Which group does your machine fall into..?
It's a 6GN0946 open ROPS.
Based on that info your 126-9401 number is good. 126-9401 has been replaced by a newer number which is 196-4681. Also a Reman Part Number 10R-5906 which ought to be significantly cheaper than buying new.
Nige do you know if that would need calibration after installation .
No it will not. Plug in and away you go.
Well I put the new control mod on today it reads no app. Cat dealer says have to bring dozer in for programing.
Cheeky SOB's............ they could have told you the initialization procedure. You can do it yourself. You need to find the Harness Code Plug. It's a grey or black rectangular 6-pin connector located right next to the ECM for the powertrain under the LH console that doesn't seem to go anywhere. All it has a a couple of short jumper leads going from one pin to another. Shown by the arrow in the photo. 1. Both the battery master switch and the key switch should be OFF. 2. Remove the Harness Code Plug. 3. Turn the Master Switch ON and then do the same with the key switch. 4. The Monitor Panel will power up and various indicators will illuminate. 5. Wait at least 10 seconds then turn the key switch OFF. (Master Switch stays ON). 6. Reinstall the Harness Code Plug. 7. Turn the key switch ON and verify that the Monitor Panel completes its self-test correctly.
Tried 4 times still says no app
The part # has changed again on the control mod . Cat says the ECM has to be updated. New part# 10r-5894
The 10R-5984 that the dealer sold you is known as EMS III. Your machine was built with EMS II and so the ECM has to be loaded with upgraded software to make it compatible. My bad, I missed that upgrade. However if the dealer has (or can make or borrow from another one of their stores) a Bypass Harness for the ECM it should not be necessary to take the tractor to them. You could simply remove the ECM and they could flash it in their shop. I used to flash ECMs while I was sitting at my desk. See attached. Even if the dealer has a machine of a similar type sitting in their shop (fair chance - t's a list 6 pages long) they could temporarily install your ECM on a machine to flash it, meaning a Bypass Harness would be unecessary.
I hauled the dozer to cat for update.service manager calls 4 hours later says new module I put on is bad want update to ems111 . I thought it was ems111 he says ecm has nothing to do with it. I thought the ecm had to be updated to ems111 to be compatible with the new module?
I must be brain-dead today........ The software has to be flashed into the new 10R-5894 Monitor System Module, not the Power Train ECM. See about half-way down Page 9 for the details. I saw the bypass harness and jumped to the wrong conclusion. The Module you bought is EMS III by the way. See the attachment. The EMS III Module for your D5M is P/N 252-4501. 10R-5894 is listed as the Reman option for 252-4501.
I don't understand why I buy the part cat says is for my machine.Then put said part on my machine.Then have to carry it to cat to program the part.when they could flash the part with it off the machine.
100% correct, and you should be confronting the Service Manager with the document from post my #13 above as proof. Again, apologies for the confusion between the Monitor and the Power Train ECM, but either way it should only have been necessary to carry an electronic component to the dealership and have them program it there, not the complete machine.
The new module I installed would not flash. Cat said bad module so they ordered another one installed it at cat.It would not flash also.They determined it was wrong one. They ordered another one it worked. And it fixed the gauge problem.Thanks for help Nige !
Do you have any idea what Part Number they finally ended up installing that worked..?
10r-5894 was the right one and that was the # on the box.But the # on the module was a new #. It was not a reman #. Cat said it was a packaging error.
Call me suspicious but I'm betting they had a batch of Reman modules out there that aren't 100%......... Provided they didn't charge you for the service, happy days.
There's still a problem dealing with same thing.
Caterpillar was giving a new number of450-2430 and reman of 10R5894 but looking at parts the new number goes back to a 20R number but file would not load talked to cat they figured out it has to be 5698638 and that reman goes back to the 10R number
NPR shows your original module 252-4501 services to TWO possible Part Numbers depending on what model of machine the control is to be used. See below. 450-2340/20R-8925 (appears to be mostly for use on Medium Wheel Loaders + 587T Pipelayer) 569-8638/10R-5894 - all other models.
Yes sir that's what we looked up and saw also, but they had a new 450-xxx with a 10R-xxx
