I do wish we could data mine these log files, ran into several well we data mined the log
file meaning the csc, the box over temped, then you hear replace it I would love to see the
data

Last I heard they were working on that, but if it does have VT, you do have some hope of
seeing something.

I did speak with teck support on this and they said it only needs to be replaced if there is
a DOC outlet temp high code or a SCR oultet temp high code. In my case they had us run
a successfull regen. NOx efficiancy was good and no other issues were found during the
regen so just the one box was replaced and they had me replace the rear jake solinoid as
there was nothing wrong found with the ATD checklist.

I seem to recall the GHG17 regens being shorter but I couldn't find anything. A customer
is asking. Are they shorter regens?

Whats is the doc "light off temp" for the mcm to command the 7th injector to begin
dosing?

Talbert_Simonia

‎12-31-2018 09:42 AM

The DOC inlet temperature should reach 550 degrees. Then it commands the HC Doser to
open the HC injector to open. But the front Jake Brakes should have been at 100% by
then. And the Actual Fuel Mass should be between 100 and 160 mg/h. If the Actual Fuel
Mass is not above 100 mg/h. Then there maybe a issue with the front Jake Brakes. If you
see the actual Fuel Mass higher than 160 mg/h. I would not worry.

When I click on "view as PDF" under Actions drop down menu, the table looses all the info.
Is that just me or is there something wrong with the base file?

I’d have to look it up and check it on my laptop. Checkout Parked regen reference‌. If you
go to PSL they are listed I believe in the workshop manuals under parked regen.

I question them as well.
Modified regen, we see torque load way above 50%, if we followed the values we would be
changing injectors on all the engines.

I did read that Before. Which is why I am asking about egr delta pressure readings. It's
saying between 2-3 psi. I am always getting usually above 4 psi at the start and it drops to
the low 3's towards the end. even on new trucks with only like 100,000 miles on them with
no emissions issues. just curious why the numbers don't line up. Cheers.

I am a corporate Detroit trainer assigned to Ryder. I actually had Ryder remove this one,
as well as the GHG 14 cheat sheet from their technician info center web site. It's a
searchable site for tech tips. In some instances, their call center and technicians were
going off of these cheat sheets instead of following specific troubleshooting steps. One
in particular was the GHG14 cheat sheet that stated a 1 box should be replaced at 2.9 psi
DOC inlet psi. We all know these can now be cleaned.
I had a tech actually repair a certain issue but decided to do a regen after the repair
(didn't need to) and became hung up on the high torque load that contradicted what is
stated in the GHG 17 cheat sheet above for TC engines. Needless to say that truck was
down for an additional 2 days with multiple parts thrown at it for no reason. I looked at the
log file, emailed the tech back and said that he fixed it the first time. (six pack of
injectors) Get that truck out of the shop now!!

Have any of you guys heard that they are no longer looking at NOx conversion efficiency
during a regen anymore on a GHG17?. I have been talking with Detroit Support. Have a unit
VIN GX2836. Customer brought in for CEL. Active 520342/16 and inactive 5298/14.
Troubleshot 5298/14 with no issues found. Troubleshot 520342/16 with no issues found.
After running parked regen and SCR efficiency test, codes cleared with no parts
repaired. This unit was just at another shop for the same active code. While reviewing the
log file, I noticed the NOx efficiency started out at 90% when the NOx sensors both came
online. By the end of the regen, NOx efficiency was at 50%. However no codes were
produced. The SCR efficiency test did show 96% efficiency. I hate releasing units for
them to show back up in a shop. I would rather fix them the first time around.

LARMF bin 1 shows .75 at beginning of SCR efficiency test. It improved to .88 by the end.
No parts have been replaced. Previous tech was working on this before it got to me.
Previous tech found DPF filters leaking around clamps which he noticed accumulation
was at 80%. Customer didn't want DPF's replaced so DPF's were cleaned and reinstalled.
Parked regen ran and SCR efficiency test ran but didn't clear inducement codes. Truck
was assigned to me at this point. Went through 520342/16 troubleshooting which led to
running parked regen again and SCR efficiency test. This time the codes cleared but
reviewing the log file, I noticed NOx conversion was poor and the actual fuel mass was
reading 50-60. Found all engine brake lash out of spec. Reset all valves and brake lash.
Ran parked regen again and fuel mass up to 120 now, but NOx efficiency still poor. Ran
low temp ATD, which everything looked ok, ran another regen with poor NOx efficiency. I
removed the dosing unit at this point while it was still hot to see if issue with dosing when
hot. Measured about 120 ml each time.

I actually verified no def buildup in one box by scoping with doser removed. No virtual
tech or subscription not enabled. I'm would suspect a degraded scr as well but Detroit is
advising no problem found. This unit is still under warranty, so I don't think it is wise to
replace the scr at this time. It would probably get kicked back to us. The log files I have
are 20 mb or more. I would have to redo the logs to make smaller. So I could attach them.

Deactivated user‌was not looking for virtual tech data, he’s looking for the fault history
data. It’s a tab in diagnostic link under fault codes. Should be next to virtual tech tab.
You can change the display to 180 days. Every time you connect to a truck, the codes are

saved as data to upload to the server. So when you connect to the server, those codes
get saved to the server and are able to be viewed with the fault history tab.

like this. Im not a computer guru maybe a issue with web browser??

I usually take screen shots of the chart and piece it together. I have done it for several
other regen reference sheets. I’ll get this one at work. And post the picture in the
comments. Then you can save the picture from my comment, open and print it.
