Complete Freightliner Fault Code List (PID, MID, SID)
Once the electronic and technological age took over, there had to be a method to guide repairs. The simplest solution was to create fault codes. Some are easy to understand and others are not. It is a good thing there are lots of lists.
Freightliner is like a lot of other manufacturing companies. They have created their own fault code list to make sure their products can be repaired correctly. In this article, you will find the complete list of Freightliner PID, MID, and SID fault codes to make your repair life simpler.
To learn about these fault codes and other pieces of vital information, just continue to read our article. It has those codes as well as other important information so you can find what is wrong with your Freight liner engine quickly
Freightliner Fault Codes
The J1587, J1708 & The J1939 System
It all started in the early 1990s when the SAE or Society of Automotive Engineers decided that the industry needed a standardized system for onboard networks.
The SAE decided to do this to avoid the discrepant and proprietary protocols adopted by the manufacturers of light-duty vehicles. So they developed the original two-layered system some trucks still use today.
This original system used what are called designators and they are - the J1708 – the physical layer (i.e., or wiring), and J1587 – the message layer or data format. To read this information, the 6-pin Deutsch connector was invented to provide access to this data and other key information.
The problem with this original system was that it was too limited in scope and the amount of data and sophisticated components that could be used. It operated under a network speed of 9600 bits/second.
This was just too slow and probably got in the way of technological upgrades that required more sophisticated data communication systems to work properly. This spurred the SAE to develop a better system of communication where more components could be supported
The Association started off by using the then current CAN or Control Area Network that was used for the 1980s light vehicles. Calling it the J1939, the SAE customized everything so that the data speed rate was elevated to 250K bits per second.
This improvement became a success and by 2005 most heavy-duty truck and engine manufacturers had adopted this system for many of their vehicles and motors. The J1939 was also given its own connector and it was called the 9-pin Deutsch connector. What this design did was accommodate the needs of the J1587 & 1708 systems as well as the new 9-pin wiring and a spot for a 2nd CAN connection.
Both systems are still in use and you will have to determine if your truck uses the J1708 system or the newer 1939 system. If your truck is more recent, it may be using the updated J1939-14 system which communicates at a speed of 500K bits per second.
This information is important because to diagnose the different fault codes in this and other lists, you need a reader that can work with any or all of these communication systems. (source)
The complete changeover to the new J1939 system took place around 2013. if your truck is older than that, you may have the older J1708 system
Freightliner Fault Code List (PID, MID, SID)
You may hear these letters spoken a lot but are not sure of what they mean. Here is a little table to provide at a glance, what the letters stand for and what they do
| PID | Parameter Identification | Identifies data being displayed |
| MID | Message Identification | System message is coming from |
| SID | SubSystem Identification | Specific location of the problem- category is broken down into the following- Common, Engine, Brakes & Transmission SIDs |
| PPID | Proprietary Parameter Identification* | Volvo & MACK fault code system |
| PSID | Proprietary SubSystem Identification* | Volvo & Mack fault code system |
* Not just Volvo and Mack, other manufacturers have added their own SIDs to further complicate the system. You would have to get the lists for these directly from the manufacturer.
PIDs go from 1 to 511 which may seem like a lot but when you compare it to the SPN list it is a minute number. The SPN fault code list is from 0 to 50,000+. However, you need to be careful as not every manufacturer uses every SPN fault code. CAT is an example of one manufacturer that does this.
The FMI, not listed here goes from 0 to 21 with some extras reserved for the SAE to add to this code list.

Some Final Words
It is a good idea to print the code lists we provide. You may not be in a position where you can access a computer and look them up. Make sure to keep them in a safe place {and we know once you do that you won’t find it again}.
These code lists are invaluable not only for when you are doing your own repair work but also to monitor the mechanics so they do not slip in extra work and pad the bill.
Unfortunately, there are still mechanics that do that despite the many investigative journalists who expose this practice. Information is still king and the more information you have the better protected you will be and the easier your repair will go.
