Reflash rev b

[Jeepstang]

I was looking and did not see anyone who has had the rev b flash done yet.

Today at just under 3800 miles the mil light came on while my wife was driving my truck. she said it sounded strange then cleared up. The light went out and I am not able to get any codes from the instrument cluster. I had rev a done about a month ago and this is the first time in the trucks history of any issues. Tomorrow I am bringing it to a Dodge dealership to have the rev B flash done and to see if they can figure out why the light came on once then would not come back on for me. I will post an update once I know the answer.

 

[Jeepstang]

Well I guess I am the first to get the rev B done

my code was related to the turbo not spooling up the way it should be

P2262 My thought was it would be best to get the flash done and see if the code comes back before repacing the turbo unit.

 

[BBeck]

I still have REV A and soon after the CEL came on. It has been going on and off periodically since. Never any codes. Sometimes the truck will feel a little sluggish when the light is on, but it is never on more than a day and there is no apparent pattern to cause the CEL to come on.



Have you noticed a change between Rev A and Rev B? I noticed that the factory setting would cause a lot of regens. but they were short. Rev A causes less regens. , but they stay on for a long time.

I only drove it home from the dealership. i was not able to get any codes either on the cluster. when he connected the wireless scanner at the dealership that is when he was able to see the code in memory.

i would bring it in and have them check to see what is causing the light to come on. with mine once the key was turned off the light went off.

i think it needs to see the issue 3 times before the light comes on

Good luck on the resolution of the P2262 code being thrown. Revision A does not resolve the problem, It still comes up for me every week. Dealer thinks the turbo is being carboned? up by the EGT system not programed properly. So far I think DC does not have a fix on the programming of the system. The diesel tech just got back from school last week and also said the turbos are on backorder but replaceing them hasn't been a fix either. I have a feeling the EGT system is dumping too much of the exhaust back through the turbo setting a code and possibly carboning up the sliding turbo sleeve. I know one thing, I'm getting tired looking at the check engine light and making trips back to the dealer.

 

[Jeepstang]

Yes now this is on 2 threads by bad I wanted to see if anyone had rev B done yet and did not know at the time what code I had

as I posted in the other one my light came back on and a Turbo will be ordered Monday

Rev B is only a tech note regarding the flash procedures. Check the other thread. I had mine done today. Nothing significant to report yet.

that is not correct

i have the flash printed out here. it is listed to be a different flash all together

if it was the same i dont think it would have let the tech put on the B flash since the A was already on there

 

[Caveman]

You can flash the ECM with the same program all day. I think we established Rev B on the other thread.

 

[Jeepstang]

According to the dealership and Chrysler it is different

I have read the flash and as I understand it it is different from rev A it reads something like this







THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 18-033-07 REV. A,

DATED JUNE 12TH 2007 WHICH SHOULD BE DELETED FROM YOUR FILES. THIS IS A COMPLETE REVISION AND NO ASTRICKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.











please correct me if I am wrong for assuming this is a complete revision

The dealer reflashed my truck to Rev. B today. I'll post the exact code number they found and the exact notes in the service tomorrow. It had to do with the EGR circuit open and soot on the exhaust sensor.

THIS IS A COMPLETE REVISION AND NO ASTRICKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.

This means there is no quick way to visually scan the TSB for differences between it and Rev. A, which it supercedes.



The only way to find any real differences would be to carefully read the two, side by side, and point-by-point, to see if what is actually done is the same, with only the instructions (to the tech) for doing it being clarified/simplified.



The actual wording for Rev. B can be read at this link:



http://dodgeram.info/tsb/2007/18-033-07.htm



The multiple steps and complexity of this TSB do not allow for carelessness in implementation.



It might be helpful to tactfully emphasize this point when talking with a service dept. (Having a copy in hand couldn't hurt. )



[A less-than-conscientious service tech with an "I already know how to do this!" attitude, could easily miss the CAUTION note in the "Overview" (re. "bootloader" software), for example. This could account for some reports of no-change after supposedly having the flash done. ]



I'm guessing that finding a service tech who happens to be both a careful worker and a very good reader is the challenge we all face in seeking service for this new higher-tech equipment.

I am wondering if this is what happened on Monday when the tech tried TWICE to re-flash the computer and it wouldn't take (that bootloader software warning was the first thing that leaped out at me when I read the TSB).



I did return to the dealer yesterday afternoon and they re-flashed it with the "update to the update. " I am assuming this was Rev B, but I need to stop in again this morning because they did not put the sticker on the engine indicating what had been done. I am sure they'll be thrilled to see me. Fortunately this flash did take and once again my truck has POWER.



The tech took it out for a drive after the re-flash and he said that it got up to 1200 degrees even before he got out of town and onto the highway. So presumably it went through one regen cycle already. I ordered a pyrometer and will have my husband install it so I can see what's happening for myself.

You do not flash the ECM with a TSB. Reflashing the ECM is similar to loading microcode. It is computer code specific to the chipset in the ECM. A TSB is a paper describing the issue and steps to solution.



The text you included refers to the complete change in procedure. As Wolfy mentions, thay have clarified and revised steps to get the ECM to accept the new microcode.

According to the dealership and Chrysler it is different

I have read the flash and as I understand it it is different from rev A it reads something like this

Hi Janet,



I suggest you steer the service personnel away from the use of vague, un-definitive terms such as "the flash", "the re-flash", "the up-date", "the update to the update", etc.



These things (Technical Service Bulletins) have number designations and revision code-letters. The actual flash procedure has a "part number", and this should be on the "modification" label applied to the front(under-hood) of the vehicle, (near the radiator, in my case), when the work is accomplished.



Failure to apply the label is just another indication of NOT doing the job attentively and thoroughly. It disadvantages the next tech who works on the rig.



Use of the definitive descriptive terminology lessens the chances of misunderstanding on anyone's part.



It is something less than reassuring to walk away only hoping that they mean what you think they mean.



Unless someone has additional info, my understanding is that the most recent TSB applying to our trucks ('07. 5, 2500/3500 6. 7L Cummins), at this time (Aug. 2, '07), is titled "TSB 18-033-07, REV. B" ( I do not have the part number, as my truck only has "REV. A". Perhaps someone with "REV. B" can provide us with it. )



Corrections welcome,

 

[Jeepstang]

Yes I understand that this TSB explains how to properly load a flash on a pcm I am not as technical as others . When I used to work on Computers and routers we just called them flashes or service packs. Wolfy is correct i hope the vauge terms that i used have not caused any issues for anyone. I just assume that people know what I was talking about.

I guess I wasted my time getting the Rev B done after I already had Rev A on it. The service department at my local dealership said the B flash was not the same as the rev A and it would be worth it for me to try the rev B flash before replacing the turbo unit. For me it's simple I am friendly with the service department and most of the time I can just drive up and be gone in 30 minutes with a flash if needed. I do have that part number that you asked for

page 3 of the TSB 18-033-07 Rev B states qty 1 04275087ab which is a "Label Authorized Modification". I choose to not have any labels placed on my truck

I predict there will be several flashes in the future and the tech said that when he connects it to the network at the dealership it tells them which flash is currently on the trucks pcm. and in my opinion they should check this anyway since alot of trucks are running around with no or incorrect labels

Corrections welcome,

Yes, you're right. I am suffering a bit of tech-fatigue, though, having spent a grand total of 8 hours trying to communicate with these people over the past week. I couldn't get them to speak to me in more than generalities despite telling them what I already knew. It was a case of finally playing the dumb female and getting my truck fixed or being *****y and having to spend even more time waiting. It was 6:30 pm last night when I finally got my truck and all I wanted was to get the keys and get out of there.



After I got home, though, I looked and found that the tech HAD NOT put the modification label under the hood, so I stopped in again this morning and asked for it. I got the label, and it says "TSB 18-033-07" but there is no indication of whether or not it is Rev A or Rev B. The tech filling out the label was taking the information off the service record and it didn't specify Rev A or Rev B, either. I suppose I should have pushed for the clarification but once again, I was just happy to get the darned thing and get out of this service department so I didn't press any further.



I can tell you, though, that if I have the option in the future, I'm driving back to Spokane or to the dealer where we bought our other three trucks.



Apologies for the lack of clarity.
