What This Code Means
Shutdown Alarm/ Fault Occurred During Crank Attempt, Start or Run; NO CRANK; Wiring Continuity Issue (Wire 18); LOW OIL PRESSURE; HIGH OIL TEMPERATURE; OVERCRANK; LOW BATTERY; IGNITION SPARK ISSUE; SHUTDOWN WIRE ISSUE; OVERSPEED; RPM SENSE LOSS; CRANK; NO CRANK CODE; RUNNING E-CODE; LOW OIL PRESSURE E-CODE; HIGH TEMP E-CODE; OVERCRANK E-CODE; OVERSPEED E-CODE; RPM SENSE LOSS E-CODE; CRANK E-CODE; Engine shutdown; Loss of engine ignition; Fuel shutoff solenoid closure; Engine shutdown and latch out; RPM Sensor Loss; Engine re-cranks
Possible Causes
- •BAD
- •BAD NO SIGNAL
- •Closure of the fuel shutoff solenoid
- •Controller does not see a valid rpm signal within three (3) seconds during cranking
- •Controller does not see an RPM signal (will not energize Wire 14/Fuel Solenoid)
- •Defective circuit board
- •Engine speed exceeds approximately 72 Hz (4320 rpm)
- •Faulty crank circuit
- •Faulty starter
- •Grounding of the ignition circuit
- •Lack of engine cranking
- •NO SIGNAL
- •No rpm signal is detected within the first three (3) seconds of cranking
- •RPM signal is lost for one full second during running
- •RPM signal is subsequently lost again
- •SHORTED WIRE 18 OR CIRCUIT BOARD
- •Shorted Wire 18
- •Shorted wire 18 or circuit board
- •Temperature exceeds approximately 293 ºF (144 ºC)
- •Wire 18 continuity fault
Suggested Actions
- 1CHECK INSTALLATION FOR PROPER AIRFLOW
- 2Clear any faults in the controller before proceeding with any running diagnostic steps
- 3Clear any faults in the controller before proceeding with diagnostic steps
- 4Controller attempts one re-crank attempt before latching out
- 5Controller waits 15 seconds, then re-cranks the engine
- 6Engine speed returns to normal operation (implicit, as the shutdown is to protect from overspeed)
