| Overcrank | Overcrank fault lamp lights and engine stops cranking after about 75 seconds. | Check for empty fuel tank, empty fuel filters, system leaks, or plugged fuel filters and fuel supply lines. Correct as required. | |
| Low Oil Pressure | Engine runs and then shuts down. The low oil pressure fault lamp is on. | Check fuel supply and for dirty fuel filters. Replace if necessary. Check oil level and replenish if needed. | |
| FAULT 1 (red) | Undedicated fault. May be factory programmed as a shutdown or non-shutdown, and as a timed or non-timed fault. (Normally set for timed shutdown). | ||
| FAULT 2 (red) | Same features as Fault 1 (Normally set for non-timed shutdown). | ||
| yellow lamp | Low engine temperature fault circuit is energized | Power outage or power disconnect (blown fuses) | Check power source supplying the coolant heater. If coolant heater, sensor or engine monitor is suspected, contact an Onan Distributor. |
| yellow lamp | Low fuel fault circuit is energized | Check fuel tank and replenish fuel as needed. If fuel in tank is adequate/full, contact an Onan Distributor. | |
| red lamp | Any undedicated (red) fault lamp is energized | Both fault functions are normally factory set and may or may not shut down the generator set. Both fault functions may be factory set optionally for non-shutdown and time delayed after start disconnect or immediate operation. Troubleshooting should be directed to the selected sensor application. If an engine monitor malfunction or sensor is suspected, contact an Onan Distributor. |

| Fault lamp lights, no fault exists. | Engine monitor or sensor malfunction. Contact an Onan Distributor. | |
| Low oil pressure shutdown; or pre low oil pressure shutdown if so programmed. | Check oil level and replenish if necessary. Contact an Onan Distributor if oil level is correct. | |
| High engine temperature shutdown; or pre high engine temperature shutdown if so programmed. | Check coolant level on radiator and heat exchanger sets and replenish if necessary. Check for slipping drive belts or for obstructions to the airflow. Contact an Onan Distributor if none of the above. | |
| Overspeed shutdown. | Contact an Onan Distributor. | |
| Any one of the red fault lamps: (or yellow pre-fault lamps if programmed for shutdown) light, but no shutdown occurs. | Engine monitor malfunction. Contact an Onan Distributor. | |
| Run lamp is not on when generator set is operating. | Indicates that a starter disconnect function is not working. Contact an Onan Distributor. | |
| Low engine temperature fault circuit (yellow lamp) is energized. | Check power source supplying the coolant heater. Problem might be a power outage or power disconnect (blown fuses). If coolant heater, sensor or engine monitor is suspected, contact an Onan Distributor. | |
| Low fuel fault circuit (yellow lamp) is energized. | Check fuel tank and replenish fuel as needed. If fuel in tank is adequate/full, contact an Onan Distributor. | |
| An undedicated (red) fault lamp is energized. | Both fault functions are normally factory set for shutdown and Fault 1 is time delayed after start disconnect while Fault 2 is immediate. Both fault functions may be factory set optionally for non-shutdown and time delayed after start disconnect or immediate operation. Troubleshooting should be directed to the selected sensor application. If an engine monitor malfunction or sensor is suspected, contact an Onan Distributor. | |
| Fault lamp lights and engine shuts down after running for a period. | Check oil level and replenish if necessary. Check coolant level on radiator and heat exchanger sets and replenish if necessary. Check for slipping drive belts or for obstructions to the airflow. Check for empty fuel tank, fuel system leaks, or plugged filters. Contact an Onan Distributor if none of the above. | |
| Engine has shut down because of critically low oil pressure | LO OIL PRES (red) indicates engine has shut down because of critically low oil pressure. | |
| Engine has shut down because of critically high temperature | HI| ENG TEMP (red) indicates engine has shut down because of critically high temperature. | |
| Engine has shut down because of excessive speed | OVERSPEED (red) indicates engine has shut down because of excessive speed. | |
