Flash code 3/5 indicates a brake pressure problem.
NOT REQUIRED
Flash code 4/2 indicates that the 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 the engine temperature is above 117 degrees Celsius for the
Ford engines, and above 130 degrees Celsius for the Deutz engines.
Air filter clogged
The engine has been running for 15 seconds or more and the battery volt-
age is still below 12.5 volts.
If a Deutz engine is installed, the 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 that the oil pressure sensor is
reading above 6.6 volts.
If a Deutz engine is installed, this indicates that the 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 that the 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 the machine configu-
ration digits. Can be reported during power-up sequence.
An unrecognized Ford ECM fault code has been received. Can be
reported during 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 that the fuel sensor is reading above 4.3 volts.
Indicates that the fuel sensor is reading below 0.2 volts.
