Cummins ISB CM850 (2003-06) Fault Code: 2215 (ISB) PID: 94 SPN: 94 FMI: 1 Fuel Pump Delivery Pressure – Data Valid but Below Normal Operational Range – Moderately Severe Level. The ECM has detected the fuel pressure in the fuel rail is lower than the commanded performance. General Information: Fault Code 2215 logs when measured rail fuel pressure remains at least 10 MPa [1450 psi] less than commanded rail fuel pressure. Once detected, Fault Code 2215 will remain active until the engine is turned off or until the measured rail fuel pressure matches the commanded rail fuel pressure. When a...

Cummins ISB CM850 (2003-06) Fault Code: 2215 (ISC) PID: 94 SPN: 94 FMI: 0 Fuel Pump Delivery Pressure Low – Data Valid but Below Normal Operational Range – Moderately Severe Level. The ECM has detected that fuel pressure is lower than commanded pressure. If the engine will not start and Fault Code 559/2215 becomes active during cranking, but no speed sensor fault codes exist, monitor the fuel rail pressure with INSITE? electronic service tool. If the rail pressure is low, check the following: 1)Fuel system prime (make sure there is fuel in the tanks and the system is primed)2)Fuel lift...

Cummins ISB CM850 (2003-06) Fault Code: 2216 (ISB) PID: 94 SPN: 94 FMI: 0 Fuel pump delivery pressure – data valid but above normal operational range – moderately severe level. The ECM has detected fuel pressure in the fuel rail that is higher than the commanded pressure. An electronic fuel control actuator with excessive leakage will result in high rail fuel pressures at idle or light load, and Fault Code 2216 will be logged. A restriction in the fuel-drain-to-tank return line can prevent excess fuel from exiting the high-pressure fuel pump. This excess drain fuel can enter the pumping chamber...

Cummins ISB CM850 (2003-06) Fault Code: 2216 (ISC) PID: 94 SPN: 94 FMI: 1 Fuel Pump Delivery Pressure High – Data Valid but Above Normal Operational Range – Moderately Severe Level. The ECM has detected that fuel pressure is higher than commanded pressure. A fuel pump actuator with excessive leakage or a damaged inboard o-ring will result in high fuel rail pressures at idle or light load. If the fuel pump actuator exhibits excessive leakage, it is possible that the fuel rail pressure will reach the opening pressure of the fuel rail pressure relief valve and Fault Code 449 may...

Cummins ISB CM850 (2003-06) Fault Code: 2217 PID: SID 240 SPN: 630 FMI: 111 Engine Control Module Calibration Program Memory (RAM) Corruption – Condition Exists. Severe loss of data from the ECM. On-Board Diagnostics (OBD) Information (Euro 4 Certified Engines): 1)The ECM illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.2)The ECM turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail. The MIL lamp and fault code can also be cleared using the INSITE? service tool.3)The fault code will be cleared from memory after 40 consecutive...
