What does the FMI code on a SPN mean?
The FMI is used along with the SPN to provide specific information that relates to a diagnostic trouble code (DTC). The FMI may indicate that a problem with an electronic circuit or an electronic component has been detected. The FMI may also indicate that an abnormal operating condition has been detected.
What does it mean when your computer says FMI?
The FMI may indicate that a problem with an electronic circuit or an electronic component has been detected. The FMI may also indicate that an abnormal operating condition has been detected. The codes are displayed in the form “SPN – FMI”.
What does the failure mode identifier ( FMI ) code mean?
The FMI may also indicate that an abnormal operating condition has been detected. The codes are displayed in the form “SPN – FMI”. The ECM / ECU also attaches a text description to the message that is transmitted over the J1939 data link.
How to find the failure mode identifier on J1939?
Failure Mode Identifier (FMI) Codes on J1939 data link FMI Description 6 Current Above Normal 7 Not Responding Properly 8 Abnormal Frequency, Pulse Width, or Peri 9 Abnormal Update Rate
What is the SPN code for the fuel filter?
SPN Code: SPN Name: SPN Description: 16: Engine Fuel Filter Differential Pressure (see also SPN 1382) Differential pressure measured across the fuel filter located between the fuel tank and the supply pump. See SPN 1382 and Figures SPN16_A & SPN16_B. 18: Engine Fuel Pressure (Extended Range) 19: Engine Oil Pressure (Extended Range) 20
What is the SPN code for the wet tank?
List of fault codes. SPN SPN Name SPN Description. 46 Pneumatic Supply Pressure The pneumatic pressure in the main reservoir, sometimes referred to as the wet tank. 51 Engine Throttle Valve 1 Position The position of the valve used to regulate the supply of a fluid, usually air or fuel/air mixture, to an en- gine.

What does a Suspect Parameter Number ( SPN ) mean?
Suspect Parameter Number (SPN) The SPN identifies the J1939 data parameter that is the source of the issue. Each J1939 parameter is assigned an SPN. See the J1939 Data Mapping Explained.pdf document for details on J1939 parameter definitions. Failure Mode Indicator (FMI) The FMI value indicates the type of issue that has occurred.
Where to find FMI values in j1939-73specification?
FMI values are defined in Appendix A of the J1939-73specification. Occurrence Count The number of times this DTC issue has occurred. Conversion Method Specifies how the SPN and FMI are to be handled or translated. This is primarily used to handle older versions of the diagnostic protocols.
What are the fault codes for MaxxForce 7?
A few weeks later, truck derates, and oil burns again. Truck overheats, and warning lights come on. Fault codes that come up are: SPN 0 FMI 0, SPN 100 FMI 1, SPN 2630 FMI 16, SPN 829 FMI 0.
What causes low power on a MaxxForce DT?
SPN- 3719 FMI- 2 Condition not found, recheck. All of these seem consistent with EGR problems, but I’m thinking you’ve gathered that much. Yep, stuck or malfunctioning egr valves will cause low power by themselves and also cause incomplete regens which will also lead to low power if the engine is detecting soot plugging. dcwjr Thanks this.
