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.. 157: 15: Amber: Engine Injector Metering Rail 1 Pressure: Injector Metering Rail 1 Pressure - Data Valid ButAbove Normal Operating Range - Least Severe Level: 4731: 3031: 13:.
