How MaxxForce 2013+ Modules Work
ECM: Engine Control Module. The ECM holds both the caibration and the parameters. MaxxForce 2013+ ECMs are dealer programmable. Both the
calibration and parameters can be changed/programmed. I6 uses a different ECM than a V8.
DCU: Doser Control Unit. The DCU contains a calibration and is dealer programmable using NavKal. I6 uses a DCU while V8 does not use a DCU.
Functional info: This type of ECM and DCU communicates on the 1939 (CAN) data link. Only the 1939 data link is used for communicating with NED.
The 1939 data link is used for the entire NavKal process.
MaxxForce 2013+ I6 (MaxxForce DT/9/10)
MaxxForce 2013+ V8 (MaxxForce 7)
To see reference photos go to "Maxxforce 2013+ Module Part Information" section below.

Connecting To A MaxxForce 2013+ Engine
When NavKal connects to a 2013+ MaxxForce I6 or V8 engine, you should see data similar to the screenshot above. (further description is below)
Engine Type
Software Identification
Engine Family Rating Code
MaxxForce DT/9/10 (2013-) (or V8)
Will show an 8-digit ECM calibration name.
(ERFC) should show a 4-digit number.
Vehicle Identification Number
Will show the full 17-digit VIN.
Engine Serial Number
Will show the full 14-digit ESN.
Transmission Type
Rated Power
Total Miles
Total Fuel Used
Total Engine Hours
(not shown in screenshot above)
It should correctly reflect the installed transmission. (Unless the vehicle
has an Eaton automated manual transmission - then it is normal for NED
to show an Allison transmission)
It should correctly show the rated horsepower.
It should show the correct total vehicle distance.
- NavKal shows total miles from the ECM parameter for total miles.
- NED shows total miles from the instrument cluster.
It should show correct total fuel used.
It should show correct total engine hours.
When connecting NavKal to a 2013+ MaxxForce DT/9/10 or a 2013+ MaxxForce 7, if you are prompted to select the engine type, you need to
select "MaxxForce DT/9/10 (2013 - )" or "MaxxForce 7 (2013 - )" (shown in red box and blue box below, respectively).
It is common to confuse this engine type with the MaxxForce DT/9/10 (2010-2012) or the MaxxForce 7 (2010 - 2012). Selecting the wrong engine
type will result in either error 84 or 89 during the NavKal programming process. You can use the bullet points below to tell the difference between
2010-2012 vs 2013+ MaxxForce DT/9/10.
Looking for sales code 0012XAN, 0012UNN, or 0012UNP is the only way for technicians to tell the difference between a 2010-2012
and a 2013+ (including 2015).
2013+ MaxxForce DT/9/10 will show 0012XAN, 0012UNN, or 0012UNP in the Service Portal "Components" tab.
2010-2012 MaxxForce DT/9/10 will not show 0012XAN, 0012UNN, or 0012UNP in the Service Portal "Components" tab.
You cannot use the EPA date shown with the engine information in the Service Portal to determine if you're working with a 2010-2012 or if it
is a 2013+.
You cannot use the "Emissions, Calender Year Date" listed in the Service Portal Components tab to determine if you're working with a 20102012 or if it is a 2013+.
Return to Top
Source Addresses
The ECM broadcasts source address 0 (zero).
The DCU broadcasts source address 61 (sixty one).
The ECM and DCU source addresses are broadcast only on the 1939 data link.
These source addresses can be seen in the sniffer in either NED or NavKal.
If you are using a Nexiq Communication cable, you could check the Nexiq Device Tester to see if source addresses 0 & 61 show on the 1939 data
link.

MaxxForce 2013+ Module Parts Information
If you need engine identification information, please see IK2600242.
See IK2600273 for help visually identifying various modules.
SID numbers are important to consider when replacing an i6 ECM of this era. See TR2600003 for more information on ECM SID numbers.
MaxxForce 2013+ I6 (MaxxForce DT/9/10): Look up ECM part number by VIN. Should have "SID 913" on the label. It is very common to use an
ECM with the wrong SID number for this specific engine type; however, that ECM will not be programmable to your 2013+ VIN.
MaxxForce 2013+ V8 (MaxxForce 7): Look up ECM part number by VIN. Should have "SID 908" on the label

DT/9/10) ECM & DCU

MaxxForce 2013+ Horsepower Quotes
"SID 908" on 2013+ MaxxForce 7 ECM
label
Horsepower increases are supported for these types of I6 & V8 engines. Follow the process outlined in IK2600069 to submit a case file for a
horsepower quote. If the engine you're considering is already rated at the highest possible rating, then no increases are available. These are a few
different ratings that are the highest in their class. See the chart below for the highest ratings. There is no need to submit a case requesting a
horsepower quote for an engine that is already at one of these ratings, as there are no increases available.

International does not support changes from standard torque ratings (and vice versa). Therefore, if you have a MaxxForce DT engine with a rating of
12NUM, it is not possible to increase it to a higher one. If you submit a case file with this type of request, you will receive the response that there are
no increases available.
Return to Top
MaxxForce 2013+ Engine Swaps
See IK2600047 for information about engine swaps. Programming changes may be needed in order to accommodate an engine swap. There are
some instances where International CANNOT support an engine swap. If you have any doubts about whether your engine swap will be supported by
International, please start a case file with the Vehicle Programming group and we will let you know if International will support the swap. It is advisable
to do this BEFORE swapping the engine. The potential negative outcome would be that you install an engine that International cannot support, then
we would not be able to provide you with the correct programming.

Common Programming Issues With MaxxForce 2013+ Systems
NavKal Error 117 Module Type: ...623..
This error can be caused by communication from other modules interfering with NavKal's communication on the data link.
Fix - Either pull transmission/ABS fuses, or use the programming station. See TL2900048 for information about the programming.
NavKal Error 8 indicates that NavKal expected to see a module on the data link, but couldn't detect it.
Fix - IK2600252 provides troubleshooting steps and direction.
NavKal Error 84 or 89 indicates that you are using an ECM that has the wrong SID number or you have selected the wrong engine type in
NavKal.
Possible Symptom: ECM loses VIN or ESN after key cycle once NavKal programming is completed.
Fix - Use the ECM that says "SID913" on the label. See TR2600003 for more information on the ECM SID numbers.
NED: In order to accommodate the installation of an open breather, parameter 69250 must be changed. That parameter is dealer programmable
through NED. A case file is NOT needed.
