SPN 1321, FMI 3 - Start Relay Coil Short-To-Power

SPN 1485, FMI 5 - Power Relay Coil Open

• Power Relay • Check Condition- Key On, Engine Off • Fault Condition- Power relay coil output open circuit • Corrective Action(s)- Illuminate MIL and/or sound audible warning or illuminate secondary warning lamp • Non-emissions related fault

The ECM has auxiliary low-side drivers that can turn on warning devices or ground electromagnetic relay coils to control power to devices connected to the engine.

This fault sets if the output for the power relay is detected as an open circuit. If this fault is active the injector and ignition coil high-side will not receive power and the engine will not run.

SPN 515, FMI 16 - RPM Above Fuel Rev Limit Level

• Fuel Rev Limit- Crankshaft Position Sensor • Check Condition-Engine Running • Fault Condition-Engine speed greater than the Fuel Rev Limit speed as defined in the diagnostic calibration • Corrective Action(s): Illuminate MIL and/or sound audible warning or illuminate secondary warning lamp, disable fuel injectors or gaseous fuel control actuator to limit speed.

Recommend disabling closed loop and adaptive learn fueling corrections while fault is active • Non-emissions related fault

This fault will set anytime the engine RPM exceeds the limit set in the diagnostic calibration for the latch time or more. This speed overrides any higher max governor speeds programmed by the user. This fault is designed to help prevent engine or equipment damage and will disable fuel injectors or gaseous fuel actuator to reduce engine speed. The throttle will also be lowered in order to govern the engine to the speed set in the diagnostic calibration for Max Gov Override.
