Catalyst full message...with deletes???

[Snowfan]

I recently acquired a 2007 2500 QC 4x4 w/6. 7, man trans and 80,000 miles. The egr and dpf deletes appear to have been done correctly and it runs well and is not throwing any codes.



Yesterday it began to beep and is showing the Catalyst Full message. Since I don't have a cat I figured you guys could tell me whats up and how to shut it up.



Great truck so far. Abused in its previous life but not too bad. This is my 4th CTD, still have the other 3.



Thanks,



Eric

In addition to the cat full message I also have a problem with the throttle. When I take my foot off the pedal fuel continues to feed for a second or two. For example, if I have the cruise set and step on the clutch the engine revs up before idling down. When I shift, after taking my foot off the pedal and depressing the clutch, the engine revs like I still have my foot on the feed. Throttle position sensor???

Eric,
What programmer is installed on the truck, H&S, Smarty or some other one or were there SIMS installed on this truck? This will help us in providing you an answer on how to solve this issue.

Thanks Jim,

I do not know what programmer was used on the truck before I got it and do not have one now. From what I understand one must have been used to cancel the regen, cel's and code throws, right? I don't know what a sim looks like but all the electrical connectors I can find are empty.

It runs crazy strong compared to my 2001 2wd reg cab with mods so I assume it has something pepping it up. I've never driven a stock 6. 7 though so just guessing.

I just checked again for codes and have none.

I've noticed on my truck (stock) I have to let off the fuel pedal before I push in the clutch to shift, by maybe a second or two. Otherwise, I have the same symptoms you do, it revs up when I shift. Others have mentioned having the same thing, so I think it's common, probably the way it was designed, not some problem with your truck. If you can find some one else's truck to try you might confirm that.

 

[Jim W]

Eric, can you get back to the owner of the truck that you just bought it from? You need to have the programmer to solve any issue that will appear in the future like now with the overhead displaying Catalyst Full.
I would have the owner remove the program and than for you to install your own programmer like a Smarty JR. These are around $495 and I would read up on how to install this programmer first. This way you have the programmer and can solve any issues with the software that maybe corrupted in the future.
Sims are 100 Ohm or 300 Ohm resistors that are wired in to make the ECM think that the DPF does not need to be REGEND.
I would read this link on more information about deletes.

TLane,
Thanks for that input. It would, in my opinion, be nice to get the throttle to do exactly what I am wanting it to do but if this is normal I can live with it.

Jim,
The truck came to me through an unusual, chaotic and unfortunate series of family events, hence the abuse mentioned above. I may not be able to find the original owner/modifier but have found the dealer who sold it to my father-in-law. I sent them an e-mail with programmer questions and will call them if I hear nothing in a few hours.

Does the current tune have to be returned to stock before I can install a SmartyJr tune? As far as I can tell no sims are present.

Eric

Eric,
What will need to be done I think, is have the dealer over write the current program in the ECM with the original software for the RAM/Cummins engine. This should include the latest up-dated flashes, the engine will go into limp mode since the DPF and EGR have been removed, if operated. After the Ram/Cummins software has been reinstalled you can install the Smarty JR software over this program. The Smarty program uses the stock program and stores this in the programmer computer and than substitutes the new software that is used by the Smarty JR to keep the engine out of limp mode. You can also change the HP/TQ level by choosing the level of operation you want to use such as stock, tow or performance. I would contact Bob Wagner, he is the US distributor for Smarty, I have added his contact information below. To make sure that this can be done.

If the dealer will not help you may be able to contact M. Mullenlax a fellow TDR member. He is a local Texan who might be able to help you with the stock programming of the truck and then you can install the Smarty than.
Let me know if this works out for you and good luck.

Jim,

Great info and much appreciated. I just finished up a talk with the dealer who sold the truck. He was helpful. He said that the truck had a small device plugged into the OBDII port that prevents trouble codes and messages, when he sold it and that it stays in the port at all times.

That device is no longer in the truck. I do not know the brand or what exactly it does and does not do. The dealer can get me one for 200 if I cannot locate the one it came with. I lean towards a Smarty for 475 as opposed to replacing the OBDII thing.

I'll try to find out what this device is, exactly. Finding out where it is might forever remain a mystery. This may take a few days.

The third photo shows a hose going to the air intake that looks like it's still open on the end. Is that the case? I haven't looked at a 6. 7 in at least a couple years.

 

[RDThompson]

That had me foxxed as well. I studied the photo on a larger screen and it's an optical illusion. What we're seeing is the band clamp around the hose.

Snowfan,

I assume you know that dealer knowingly broke state and federal laws selling that truck with emissions controls deleted?

Hi Harvey. That exact thought never occurred to me. Thanks for the info.

I did not buy it from the dealer. My elderly father-in-law got suckered into the truck by some dude he went into, and out of, business with. I got it from him.

I choose to make it none of my business what other people are doing, or not doing. To do otherwise, for me, is judgmental and an awful waste of time. I try to stay focused on what I am doing, and not doing.

 

[HBarlow]

Well, if you bought it at an attractive price you should be able to start over with the aftermarket delete equipment. The SmartyJr is the most popular magic black box that most members rave about and the one I would buy if I was going to delete mine. Apparently Bob Wagner provides outstanding tech support. If the DPF and other hardware is already gone that should help you stop the annoying error messages which might even disable the engine eventually.

I recommend you pm Mike Mullenax. Mike is a TDR member and the senior diesel tech at a Dodge dealer in Athens, TX which is not far from Tyler in east TX. Mike knows a lot about the engines and the Cummins software program. I took my C&C across the state several years ago to have Mike run a software reflash because I trust him. He's a real diesel mechanic not one of the typical parts changers that many dealerships employ.

I was of the impression that once the ECM program was altered it had to be restored to original by the black box that altered it and stored the original program. I don't know what can be done in your case but Mike should be able to advise you.

I initially ignored your third paragraph not knowing if it was intended to insult me or just describe your lofty position but on second thought decided to address it.

You may reconsider that position if and when you discover the truck cannot be restored to troublefree driving. Someone may have screwed it up badly then traded it to a dealer who didn't know it had been altered. I'd guess that truck ended up in an auction and was purchased for low price by an unknowing buyer.

It can't be legally registered, inspected, or driven on public highways and streets as it is. If you can modify the ECM software to stop the alarms you may be able to drive it but if you ever get caught by an inspection station in the large metro areas of TX or in many other states, the truck will be impounded and you'll pay hefty fines. I hope you are able then to continue being nonjudgemental.

 

[Snowfan]

Harvey,

Thanks for the info, and warning, regarding the illegal setup. I'll be pm'ing Mike for his input on the programming.

As I understand it now, which is subject to change, the truck has some sort of hot tune on it. This thing sounds like a thunderstorm when I get on it and pulls hard all the way to redline. Problem is, I have no clue what the tune actually is. I would much prefer to return it to stock tune, then add the Smarty and go from there. I hope that is possible without access to the original tuner.

I had no intent to insult you nor is my position on not judging others lofty. I apologize for any missed communication.

Again, thanks for your input.

 

[Snowfan]

I spoke with Mike Mullenax at Elder Dodge today, he was very helpful. As discussed earlier, I am getting an error message in the overhead console, along with the ding, ding, but no codes.

It is not a problem to get a Smarty, H&S or whatever tuner and load its program but it would store the current, hot and cat error program in its memory. That is what I do not want. I prefer to reflash to stock, then add a SmartyJr to deal with the codes and error messages.

I will try to get one of my localish 3 dealers to reflash it to stock but if I cannot Mike said he could do it. Looks like I found a fix.

Thanks for the help

 

[HBarlow]

Good, glad to hear it. I often recommend TDR members contact Mike but normally don't get any feedback.

I'll be surprised if any of the area dealers can and will reprogram your ecm but I hope I am wrong. It would be good to know if one has a good mechanic in their service department. I have heard that the dealer at Lamesa has a woman Cummins tech who is respected. I haven't been there to confirm that.

Athens is a good long drive from Amarillo but, imo, worth it to have your truck repaired by a genuine Cummins mechanic.

 

[Snowfan]

If I strike out with the dealers up here I'll check with Lamesa. Worst case, I might enjoy a trip to Athens.

 

[woodsrat]

It sounds like to me that the truck has been flashed with EFI. If you can find a tuner in your area, they can flash a stock tune to it and then reprogram the truck.
