Dropping the truck off at the dealer in the morning due to CEL and code 245b. What is the latest flash out there? The service writer I spoke with on the phone this am said there he didn't think that there had been a new one since June but he would check. I could've sworn that there were some since then.

Thanks

 

Version AU came out end of Aug. (June is version AT)

 

Anyone have the number or the TSB?

 

TSB 18-033-07

Version AU is downloaded by the star scan tool when applying this TSB.

 

Thank you!

 

The AU flash seems to have fixed many of the problems that have plagued the 6.7L Keep your fingers crossed.

K2Cummins- Let me know if you find a dealer in the area that will do the flash... most seem pretty stingy with their Tech's time.

 

I am a little confused about the TSB number and the AU revision. My truck has had TSB 18-033-07 applied and the label indicates 55351105AT. Doesn't this mean this is the AT software release? If so, then what is the TSB number for the AU release? By the way, TSB 18-033-07 says it was released in June 07.

 

You have the AT software. The star scan tool downloads software over the Internet when it applies the TSB, so it is the same TSB but a new version of the software (AU). The dealer needs to apply the TSB again. I have a new engine modification sticker on top of my old sticker.
