Troubleshooting Guide
Glow Plug 3
E38
Current too
Low
1) Inspect wiring for
damage.
2) Consult the man-
ual.
The E38 error code indicates the ECM has detected that glow plug
#3 is drawing too much current. This can be caused by damaged
(shorted) wiring going to the glow plug, a shorted glow plug, or a
defective circuit within the ECM.
Possible Solution(s):
Disconnect the glow plug, if the E38 error does not reoccur, prob-
lem is with glow plug. If E38 error does reoccur then problem is
either damaged (shorted) wiring or the ECM itself
Glow Plug 4
E39
Current too
Low
1) Inspect wiring for
damage.
2) Consult the man-
ual.
The E39 error code indicates the ECM has detected that glow plug
#4 is drawing too much current. This can be caused by damaged
(shorted) wiring going to the glow plug, a shorted glow plug, or a
defective circuit within the ECM.
Possible Solution(s):
Disconnect the glow plug, if the E39 error does not reoccur, prob-
lem is with glow plug. If E39 error does reoccur then problem is
either damaged (shorted) wiring or the ECM itself
Debarker
Horn
E41
Debarker
Horn Fault
1) Inspect wiring for
damage.
2) Consult the man-
ual.
The E41 error code indicates the ECM has detected that the circuit
for the Debarker horn is drawing too much current (amperage).
This can be caused by damaged (shorted) wiring going to the
horn, a defective horn, or a defective circuit within the ECM.
Possible Solution(s):
Disconnect the horn, if the E41 error does not reoccur then prob-
lem is with the horn. If the E41 error does reoccur then problem is
either with damaged wiring (shorted) or the ECM.
Display
Heater
E42
LCD Heater
Fault
1) Make sure heater
is plugged in.
2) Inspect wiring for
damage.
3) Consult the man-
ual.
The E42 error code indicates the HMI has detected that the circuit
for the display heater is drawing too much current (amperage).
This can be caused by damaged (shorted) wiring going to the
heater, a defective heater, or a defective circuit within the HMI.
Possible Solution(s):
Inspect the heater wires (white wires on back of display) for dam-
age. Inspect the heater itself for damage. Ohm test the heater, the
heater should be approx. 14 Ohm's when measuring from terminal
to terminal on the heater's plug, if not, replace heater assy. If Ohm
reading is OK, replace the HMI board assy.
Note:
The heater is automatically operated at temperatures of 32
degrees F. and lower.
Hydraulic
Function
E43
Hydraulic
Function
Error
1) Inspect hydraulic
valve wiring for dam-
age.
2) Test coil for hydrau-
lic valve.
3) Consult the man-
ual.
The E43 error code indicates the HCM has detected an error with
one of the hydraulic valve coils. Displayed along with the E43 error
code is the HCM error code that corresponds to the function that
has the issue. See
for HCM Error Code
Chart.
Possible Solution(s):
The HCM error codes generally refers to issues with the coils that
sit atop the hydraulic valves, however, a damaged cable (open or
shorted) going to the valves will also cause an error. Find the coil
of the valve that was reported as having a problem and swap the
coil with another valve to see if the problem moves with the coil, if
it does, replace the coil, if not, the problem is either the cable or a
problem with the output on the HCM.
