Engine Over Temperature

Engine Communication Error

Module Communication Error

Clutch Output Failure

Engine Limp Mode Active

In order to protect the system components from
exceeding threshold limits, the system limits the
engine speed and/or disengages the clutch, which
allows you to drive the machine onto a trailer or
return to a service area.

These are the following errors that may occur:

1.

Clutch Overcurrent

If an overcurrent event occurs, the system
limits the engine speed to the Efficient
Transport Mode speed and places the
machine in Safe Transport Mode. Safe
Transport Mode limits the engine speed,
locks out the PTO, and disengages the
clutch; a Clutch Overcurrent error message
will display. Cycling the key switch to the O

FF

and then to the O

N

position clears the fault.

2.

System Overvoltage>16VDC

If the voltage exceeds 16 V, the system will
disengage the clutch and displays a System
Overvoltage>16VDC error message.

3.

System Undervoltage<9VDC

If the voltage is less than 9 V, the system
will not allow clutch engagement and display
the error System Undervoltage<9VDC. If
the clutch was engaged before the error
occurred, the system allows the clutch to
remain engaged; however, low voltage may
cause the clutch to disengage itself.

4.

Low Oil Pressure

If low engine-oil pressure is detected, the
system limits engine speed to the Efficient
Transport Mode speed and places the
machine in Safe Transport Mode. Safe
Transport Mode limits the engine speed,
locks out the PTO, and disengages the
clutch; a Low Oil Pressure message will
display. Cycling the key switch to the O

FF

and then to the O

N

position clears the fault.

5.

Engine Over Temperature

When the engine begins to overheat, the
system flashes the engine temperature
bar graph and chirps the audible alarm.
If the temperature rises above the upper
limit, the system limits the engine speed
to the Efficient Transport Mode speed and
places the machine in Safe Transport Mode.
Safe Transport Mode limits the engine

speed, locks out the PTO, and disengages
the clutch; an Engine Over Temperature
message displays. The fault clears once the
temperature falls below a safe limit.

6.

Transmission Over Temperature

When the transmission begins to overheat,
the system flashes the transmission
temperature bar graph and chirps the audible
alarm. If the temperature rises above the
upper limit, the system limits the engine
speed to the Efficient Transport Mode speed
and places the machine in Safe Transport
Mode. Safe Transport Mode limits the engine
speed, locks out the PTO, and disengages
the clutch; a Transmission Over Temperature
message displays. The fault clears once the
temperature falls below a safe limit.

7.

Engine Limp Mode Active

If the engine ECU determines that a
significant engine issue has occurred or that
the DPF requires a Recovery Regeneration,
it places the engine in a limp or backup
mode where engine speed and/or decrease
engine power. In order to protect the system
components, the module locks out the PTO
and display the Engine Limp Mode Active
message.
