Genset Maintenance Onan Genset
Code Fault Type Corrective Action
1
High temperature fault
First-level fault; engine coolant temperature
exceeded 110°C (230°F).
1. Check engine coolant level and add coolant
as necessary.
2. Check for and remove any objects blocking
the air inlet or outlet openings in the bottom
and sides of the genset.
3. Flush the coolant system to remove debris
which may be clogging passages.
2
Low oil pressure fault
First-level fault; low oil pressure cutoff switch is
open.
1. Check the engine oil level and add oil as nec-
essary.
2. Drain any excess oil if the oil level is above
the “FULL” mark on the dipstick. (The oil will
foam if the level is too high which can lead to
the loss of oil pressure.)
3
Service check
First-level fault code signifying a second-level
code has occurred.
Check the second-level fault code by momen-
tarily pressing Stop. The second-level fault will
appear.
4
Over-crank fault
Cranking time without starting was exceeded.
1. Check fuel level; refill fuel tank.
2. Check for fuel leaks; repair as necessary.
3. Prime the engine fuel system by holding the
control switch at Stop for one minute.
4. Replace engine air filter.
5. Replace the fuel filter.
12
Over-voltage fault
The controller is not able to regulate to rated
voltage.
See authorized Cummins Onan dealer.
13
Under-voltage fault
The controller is not able to regulate to rated
voltage.
Turn off the line circuit breaker on the console. If
the genset now starts and runs, the load on the
genset is too great. Disconnect the extra loads.
14
Over-frequency fault
The controller is not able to regulate to rated
frequency.
1. Disconnect any extra loads.
2. Check for and repair fuel leaks. Air in the fuel
supply can disrupt frequency. Prime the
engine fuel system by holding the control
switch at Stop for one minute.
15
Under-frequency fault
The controller is not able to regulate to rated
frequency.
1. Disconnect any extra loads.
2. Check fuel level; refill fuel tank.
3. Check for and repair fuel leaks. Air in the fuel
supply can disrupt frequency. Prime the
engine fuel system by holding the control
switch at Stop for one minute.
4. Replace engine air filter.
5. Replace the fuel filter.
19
Governor actuator fault
The controller sensed that the actuator circuit
is either open or shorted
