Flash code 3/5 indicates a brake pressure problem.
NOT REQUIRED
Flash code 4/2 indicates engine is over temperature. NOT REQUIRED
Flash code 4/3 indicates problems with the engine. Except where noted, these
faults are not reported during 2 second power-up sequence.
Occurs when engine temperature is above 117° Celsius for Ford engines, and
above 130° Celsius for Deutz engines.
Air filter clogged
Engine has been running for 15 seconds or more and battery voltage is still
below 12.5 volts.
If a Deutz engine is installed, oil pressure is below 8 PSI and the engine has been
running for at least 10 seconds. If a Ford engine is installed, the Ford ECM has
reported a low oil pressure fault.
If a Deutz engine is installed, this indicates oil pressure sensor is reading above
6.6 volts.
If a Deutz engine is installed, this indicates oil pressure sensor is reading below
0.1 volts for more than 5 seconds. This fault is not detected during crank.
If a Deutz engine is installed, this indicates coolant temperature is reading
below 0.1 volts.
All Ford fault codes except 63 are simply passed through from the FORD ECM.
They only occur if a Ford engine is selected in machine configuration digits. Can
be reported during power-up sequence.
An unrecognized Ford ECM fault code has been received. Can be reported dur-
ing power-up sequence.
This fault only occurs with a Ford engine. It occurs when no responses are
received from the ECM for 2.5 seconds. Can be reported during power-up
sequence.
Indicates fuel sensor is reading above 4.3 volts.
