6.7L Cummins Forum

Squid · #1 (**permalink**) 05-01-2009, 08:20 PM

I got this emailed to me and it doesn't look good for owners of 09 Dodge Ram pickups with the 6.7L Cummins(And probably other vehicles too).

From this TSB if you install anything that changes the paremeters of the ECM your truck won't start and then when you have it towed to the dealership and they fix it, it's not covered under warrenty. I'm not sure how this is legal but I'll leave that to Sema and their lawyers.

SUBJECT:
No Crank, No Start - Malfunction Indicator Lamp (MIL) With DTC U1601
MODELS:
2009 (DH/D1) Ram Trucks (2500/3500 Pick Up)
2009 (DC/DM) Cab Chassis (3500/4500/5500)
NOTE: This bulletin applies to 2009 vehicles equipped with a Cummins 6.7L diesel
engine (Sales code ETJ) built after March 04, 2009 (MDH0304XX)
programmed with bootloader software number 00 06 01 (or later). 2007 and
newer vehicles that have had the ECM replaced with the new bootloader
software will also be effected.
DISCUSSION:
This bulletin explains a Malfunction Indicator Lamp (MIL) illumination due to Diagnostic
Trouble Code (DTC); U1601 - ECU Application Software Code 1 Missing Or Corrupted.
If the Engine Control Module (ECM) does not have a calibration installed, or has an
unapproved calibration installed then the ECM will be in a Read Only Memory (ROM) boot
state. The ECM will have power but the lack of approved software will not allow the vehicle
to be started and driven. No further diagnostics of the ECM will be available at this time.
This code will be cleared and issue resolved when the ECM is updated with the correct
approved calibration. Refer to the DealerCONNECT > TechCONNECT > Service
Information for more detail.
DTC U1601 set outside of the dealership with a no crank, no start condition caused by
unauthorized (up-rate) software will
NOT be covered under the terms of the warranty.
DTC U1601 code may also be set when a legitimate flash is interrupted for any reason.
This bulletin also involves explanations of the effects that aftermarket “Up-rate Kits” have
on Cummins engine and emission systems.

NOTE: Replacement ECM's supplied by Mopar may also contain the secure
bootloader software, thus the conditions listed above may apply to 2007 and
newer vehicles if the ECM has been replaced.
NUMBER:
18-007-09

GROUP:
Vehicle Performance

DATE:
March 13, 2009

CAUTION: Some customers may come in requesting a software update because the
up-rate software does not recognize the secure bootloader software
(even though the controller may be up to date). This should serve as a
warning that the customer is attempting to tamper with the calibration in
the vehicle's ECM.
Up-Rate kits are numerous and may include aftermarket software downloads.
Engines that have had tampering will generate excess soot and may damage the
Turbocharger, Diesel Particulate Filter (DPF) and Oxygen Sensors (O2) and/or other
emission system(s), air handling or fuel control components.
Some of the changes caused by Up-Rate kits (but not limited to) :
·
Engine calibration, including emissions.

·
Governors, including engine speed and vehicle top speed.

·
Torque and horsepower (which may cause other drive line component damage).

·
Diagnostics, preventing MIL illumination.

·
Drivability and torque management control.

DIAGNOSIS PROCEDURE:
1. Refer to the detailed service information available in DealerCONNECT >
TechCONNECT under: Service Info > 28 - DTC-Based Diagnostics > MODULE,
Engine Control (ECM), 6.7L > Diagnosis and Testing > U1601 - ECU Application
Software Code 1 Missing Or Corrupted.
POLICY:
Information Only.

That doesn't sound legal, but it does sound like they read the forums and know people are taken off there mod’s for service.

Sooo Im confused. My 09 was built 11/08. Does this mean I am safe as long as my ECM isn't replaced? or is it all about the software, and how do I know I have the bootlegger software? this is BS if you ask me

That my friend is a great question.

If you haven't been to the dealership for any sort of flash I would think you're okay but anyone with a Cummins 6.7L (07 and beyond) that goes in to the dealership after march of 09 for any sort of Flash or reprogram including a ECM or PCM will probably have this new boatloader software installed. The Boatloader software can be updated at any time but not downgraded so once it's installed you're screwed.

Since the Edge doesn't reprogram the ECM like the BullyDog and some of the other Tuners I don't think owners with it will be effected. ( But I also don't want to be a guinne pig either

)

Thanks for the info Squid... Hope you figure your truck out. are you sure you only have 50K emissions warranty? I would almost bet my girlfriend I read in my manual that I have 100K warrant... And yes, ALMOST bet the women!!!

The warranty is 36,000 miles for the basic.

50,000 miles for emissions unless you live in California and then it's 100,000 miles.

The engine is warranted for 100,000 miles for all.

No problem and thanks for sharing the info from Smarty which confirms that any truck that goes in for a flash now can have this boatloader software installed nulling the use of any programmer that uploads changes to the ECM. Looks like my Edge with Attitude was a good decision after all....................I hope.

Welcome to the site!
