Over the years the SAE has developed a fault code system to help mechanics and DIY mechanics figure out what was wrong with their modern engines. This system is supposed to make repair work a little easier to diagnose and repair. It doesn’t always work out that way.
The different fault codes do have meaning. They are employed to help everyone working on engines find the problem without too much guess work. The more codes you see, the more accurate the location and problem are. The biggest problem is that not all manufacturers use the same code. Cummins is one of them.
To learn more about the Cummins fault codes and how they relate to the SPN and FMI system just continue to read our article. It has those codes and the relation to other networks so you can find the identity of the problem and location faster. It may be a wise idea to print out the tables that follow so you have them on hand when you need them.
Fault Code Systems Definitions
It does not do anyone any good if they do not know what all the different letters mean when they appear on the screen on your dash. All the letters and numbers have a clear meaning which should help you when you are trying to clear those codes and be able to drive again.
1. J1939, J1587, & J1708- This is the system under which most fault codes operate. The first number refers to the hardware like wires, etc while the second and third numbers refer to the non-tangible communication that takes place over the J1939 system. Cummins uses the J1939 system.
2. SA- Source Address- This is the type of computer where the code is coming from:
Engine control module (ECM) = SA 0
After treatment control module (ACM) = SA 61
Body control module (BCM) = SA 33
Antilock braking system (ABS) = SA 11
Transmission control module (TCM) = SA 3
Different manufacturers may use different SA numbers to indicate the same computer
3. MID- is also a Source Address and depending on the number following it can lead to the computer triggering the code
4. PID- Parameter Identification
SID- Subsystem Identification
PSID- Proprietary Parameter Identification
PPID- Proprietary Subsystem Identification
In these cases, all OEM companies use the SAE documents that spell out the codes for SID and PID so there is no confusion. For example PID 84 = road speed; SID 146 = EGR valve but ECU specific; PPID 326 - soot level but Volvo and Mack specific.
5. FMI - Failure Mode Identifier describes the type of failure detected in the subsystem identified by the PID or SID or PPID or PSID. This just tells you what is wrong with the component that is not working right.
6. SPN- suspect parameter number identifies the specific component or condition that is triggering the fault code.
After all that, Cummins only uses one code number which relates to the SPN and FMI portion of this code system. You can see that by looking over the tables below. These definitions should help you understand what is going on when you see the fault code illuminated on your screens.

Some Final Words
Working on engines is not like it was in the early to late 20th century. Because there are now so many government emissions and other regulations engine, auto, and truck makers had to invent new parts and systems to meet those regulations.
The problem is not the many fault codes to monitor what is wrong with your motor. The real problem is that these newly invented parts cost far too much. Sometimes it is just better to buy an old clunker to save a lot of money or buy the extended warranties to protect yourselves.
