The ECM monitors the voltage level on this circuit. If it detects a low voltage when the signal is commanded ON, it records this fault code. This fault code can be caused by a short circuit to ground in the starter lockout relay, OEM harness, or connectors.
1)Replace the starter lockout relay2)Repair or replace the OEM harness.
Cummins ISM CM875 (2003-06) Fault Code: 584 PID: S39 SPN: 677 FMI: 3/3 Starter Relay Driver Circuit – Voltage Above Normal or Shorted to High Source. Open circuit or high voltage detected at starter lockout circuit.
Cummins ISM CM875 (2003-06) Fault Code: 559 PID: P157 SPN: 157 FMI: 1/18 Injector Metering Rail 1 Pressure – Data Valid But Below Normal Operating Range – Moderately Severe Level. The engine control module (ECM) has detected that fuel pressure is lower than commanded pressure.
