Cummins Campaign "Recall" on Catalyst

[Toribk]

Typically, you have a NOX Sensor upstream of the SCR and one downstream of the SCR you had replaced under the Cummins Warranty Campaign.

If the NOX Sensor downstream of the SCR cannister failed or was the one that was replaced as a result of a specific fault code, the SCR may have been the contributing factor and replacement of the sensor unwarranted?

I am assuming that the Cummins shop initially used their insite software to determine which NOX sensor was triggering the check engine light and tested that particular sensor to see if it was, in fact, faulty before replacing it.

They should be able to share that information with you or it may be noted in your work order/receipt under the description of services performed. It should also detail the part description and part numbers of items replaced.

Let us know what you find out.

Toribk. Thanks for the discussion and ideas. I confirmed with Cummins (a distributor) that the NOX sensor in front of the SCR went bad. Expensive part and a little hard to get to without taking the inside panel off for access. SCR was replaced due to campaign but appears to have been a separate issue. Thanks again for your help

You can Google "Recent Cummins Warranty Communications Listing"*and then click on either campaign. C2112 is for the CM2250 engine designation and C2053-A is for the CM2350 engine designation.

The fastest and easiest way to determine if your model year engine is listed in the SCR campaign or any other Cummins warranty or recall campaign, is to log on to www.cumminsquikserve.com and create your account with your engine number. It is free and besides the campaign, it provides you access to owners manuals, parts schematics, maintenace and repair manuals and troubleshooting manuals.

When you click on the "Service" tab on the home screen of the Quickserve page up top, any OPEN campaign will come up on the screen in RED.

If you don't get the big red OPEN under the Status tab, there are currently no campaigns for your particular engine.

If you do, click on the campaign number on the "Service Line Bulletin" and in the body of the text, there will be two Excel attachments that A. Will show the affected engines you can scroll through by serial number and B. The Affected SCR part number and the new replacement part number.

The affected SCR part number is the bottom number embossed on the catalyst toward the tailpipe. (See photo) If that bottom number matches any on the list under Attachment B,
your SCR is affected and needs replacing.

Hope this helps.




Attachment 269477

My online campaign shows a C2113 but there is nothing to click on to see the campaign nor can I find anything on the Cummins site that has information on this one.

Mine, too. It looks like C2113 was just initiated last June. I wonder if it's an extension of C2112? And to make matters worse in my case, the spot on the catalyst where the numbers are is covered up by the wide metal strap that holds it to the frame.

Don and Mike,

I can't find anything on C2113 either, so I am assuming you both are seeing that specific Warranty Campaign when you log on to the Cummins Quickserve homepage with your engine serial numbers.

If you are seeing "OPEN" in red under campaigns on the home screen, then your SCR is suspect and needs to be inspected by an authorized Cummins warranty repair center......I prefer a Cummins Coachcare.

Unfortunately Mike, the retaining straps can conceal the serial number of the catalyst and calls for Cummins to remove it for verification. Fortunately, there is no cost to the consumer if you have the OPEN campaign, but is inconvenient to say the least.....especially now that Cummins has removed the Affected SCR part numbers list (Attachment B) from both campaigns with an update revision this month. I'm glad I saved a copy beforehand.

I have yet to understand why they did that, but have my suspensions [emoji2955]

Just received my Vehicle Registration Renewal Notice from California DMV today. Although my rig is over the weight limit for smog check, the DMV is requiring the proof the Cummins Recall C2114 has been completed in order to renew the registration. For some reason, I had a feeling that this would be the case, at least in California. Fortunately, I already had the work done at Cummins while in for annual service.

Is the SCR replacement the ONLY thing that is done as a part of this campaign? I am asking because, as happens on the internet, things are being said that they also install new programming that may "derate" the engine from it's published performance (less HP). One individual even stated that the service manager where he had the work done told him that, after it was done, then refused to restore the old code.

Now, I understand that the internet is full of B.S. and for some reason certain people just have it in their nature to try to start trouble through false statements. But, since several here have actually had it done....comments?

I have contacted Cummins directly and they sent me the fix list as the SCR but are not responding to the negative that there may also be new program downloads that would intentionally lower engine performance to meet CARB emissions specs even though I am specifically asking the question of them.

[CalifCruiser]

As far as I know, it was just for a replacement SCR, don't know anything about a programming change and the rig runs as well as ever, I suspect that a programming change or "derate" is not correct information. I have the sticker in the engine area and had to mail the card (signed by Cummins mech) to DMV at registration time.
My local Cummins dealer was great, I dropped it off to them on a Monday and then picked the rig up two days later on Wednesday. Had the work done along with my annual service.

[Toribk]

That has been my experience as well and those of my associates who have had the recall campaign completed.

None have reported any re-flash of the ECM...at least not to me.

I believe CA is the only state DMV requiring the orange completion card from Cummins, but that is where the initial campaign originated from.

I laminated mine and keep it in the coach.

Mine is same or better power after. I know they need to run a program for testing. Cummings requires it for warranty.Its a long test.
