The Cummins Code SPN 5357 FMI 31 is a diagnostic code related to the engines electronic control system. It indicates that there is a problem with the engines fuel injector(s). This code is typically set when the fuel injector(s) are not functioning properly, which can cause the engine to run rough and/or misfire.

Definition

The Cummins Code SPN 5357 FMI 31 is a diagnostic trouble code (DTC) that stands for Fuel Injector Circuit Malfunction. This code indicates that there is an issue with one or more of the fuel injectors in the engine, causing it to run rough and/or misfire.

Causes

The Cummins Code SPN 5357 FMI 31 can be caused by a variety of factors, including: faulty wiring or connections, worn or damaged fuel injectors, defective fuel pressure regulator, blocked fuel filter, low fuel pressure, or a faulty ECM (engine control module).

Tools Required

In order to diagnose the Cummins Code SPN 5357 FMI 31 correctly, certain tools are required. These include an OBD-II scanner, an infrared thermometer, a voltmeter or multi-meter, and possibly a pressure gauge. Additionally, some basic hand tools such as pliers and screwdrivers may be needed as well.

Steps To Diagnose

1. First check for any fault codes stored in the engine control module (ECM). This can be done with an OBD-II scanner.
2. Next check for any signs of faulty wiring or connections by visually inspecting all of the connectors and wiring harnesses associated with the fuel system.
3. Then use an infrared thermometer to check each individual injector for proper operation by measuring each injectors temperature while it is running.
4. After that measure each injectors voltage with a voltmeter or multi-meter while it is running to ensure proper operation.
5. Finally use a pressure gauge to check the fuel pressure at idle and under load conditions to ensure that it is within spec range for your vehicle’s make and model year.

Replacing Parts

If any of these tests indicate that one or more of the injectors are not functioning properly then they may need to be replaced in order to resolve this issue and prevent further damage from occurring to your vehicle’s engine components. Additionally any faulty wiring or connections should also be replaced if needed in order to ensure proper operation of all components involved in this system.
