Communica-
tion Error
E19
ECM Com-
munication
Loss
1) Verify communica-
tion cable is plugged
in.
2) Consult the man-
ual.
The E19 error code indicates that the system has lost the ability to
communicate via the CANBus with the ECM.
Possible Solution(s):
If the system is communicating with all of the other modules (as
indicated by the revision number next to each module listed in the
diagnostic screen) then the problem is either a tripped breaker for
the ECM, or a defective ECM. If there are other modules not com-
municating then the problem is cabling. Take note of which mod-
ules are communicating and replace appropriate cable.
Communica-
tion Error
E20
MCM Com-
munication
Loss
1) Verify communica-
tion cable is plugged
in.
2) Consult the man-
ual.
The E20 error code indicates that the system has lost the ability to
communicate via the CANBus with the MCM.
Possible Solution(s):
If the system is communicating with all of the other modules (as
indicated by the revision number next to each module listed in the
diagnostic screen) then the problem is either a tripped breaker for
the MCM, a defective communication cable that runs from the
MCM to the ECM, or a defective MCM.
Note:
Once the error is acknowledged on the control panel, question
marks on the display in place of the head position is normal with
this error (the MCM communicates the head position)
Communica-
tion Error
E21
HCM Com-
munication
Loss
1) Verify communica-
tion cable is plugged
in.
2) Consult the man-
ual.
The E21 error code indicates that system has lost the ability to
communicate via the CANBus with the HCM.
Possible Solution(s):
Check to see if the HCM power fuse (F4) is blown, if so, replace. If
fuse keeps blowing, the problem is either a shorted power cable
going to the HCM or a shorted HCM. If fuse is not blown and the
system is communicating with all of the other modules (as indi-
cated by the revision number next to each module listed in the
diagnostic screen) then the problem is a defective HCM.
Note:
Before replacing HCM, double check that all other modules are
communicating properly by operating the other modules - the
hydraulic functions should be the only ones unable to function.
Communica-
tion Error
E22
HMI Com-
munication
Loss
1) Verify communica-
tion cable is plugged
in.
2) Consult the man-
ual.
The E22 error code indicates that the HMI is not communicating
with the rest of the system.
Possible Solution(s):
This is usually caused by a defective, damaged, or loose cable
that runs from the back of the control box to the hydraulic box
receptacle, poor connections or damaged wiring inside the control
box from the HMI to the receptacle on the back of the box, or poor
connections/damaged wiring inside the hydraulic box from the
receptacle to the HCM. If cabling/wiring is not the issue then prob-
lem may be defective transceiver on the HMI, replace HMI.
Transducer
Error
E23
Loss of
Transducer
Signal
1) Inspect solenoid
wiring for damage
2) Test Debarker sole-
noid coil
3) Consult the manual
The E23 error code indicates that the MCM is not receiving signals
from the Transducer.
This can be caused by a defective/damaged Transducer cable,
splitter cable (receptacles on bottom of power box), Transducer, or
the MCM.
Note:
The Transducer circuit can be difficult to isolate the failed compo-
nent in due to the high-speed nature of this circuit. Replace com-
ponents in this order: 1. Transducer Cable 2. Splitter Cable 3.
Transducer 4. MCM
