8.5 Cab Display Module Error Codes
The cab display module (CDM) displays error codes when there is a fault with one of the sensors that monitor and control
windrower operation. Use the list of error codes to help identify a specific problem with the windrower.
NOTE:
In the case of dual codes being shown for an item (primarily the solenoid valves), the first code indicates a SHORT CIRCUIT
condition, while the second code indicates an OPEN CIRCUIT condition. That is, E41 would be a SHORT in the reel aft
solenoids (P55, P59), while E141 would indicate an OPEN circuit.
Codes
CDM Display Description
E1
——
E2
RTCH NOT ALLOWED
Return to cut activated with the header off
E3 CDM CAN BUS ERROR
E3 is triggered when the CDM module can not transmit and/or
receive CANBUS. Check CAN signals on pin 22, 23, 24 and the
power ground on 9, 11 and 25 in connector P38.
If all signals check out OK, check CANBUS cabling and end bus
terminations in place. The terminators are located behind the
Cab Display Module (CDM) connector P41, and near the engine
Electronic Control Module (ECM) connector P40. The resistance
should be 120 ohm resistance
E4 HDR DRV NOT ALLOWED
HEADER ENGAGE switch activated while in engine-forward
E5
CHECK HEADER ID
Header ID change has been detected while the header was
engaged
E6 TEMP GAUGE SHORT
Wiring/connection problem
E7 SPEED STICK SHORT
Wiring/connection problem
E8 HEADER ENABLE SHORT
Wiring/connection problem
E9 WCM ENABLE SHORT
Wiring/connection problem
E10 CDM INTERNAL ERROR
A generic internal CDM error summarizing a number of internal
problems
E11 CDM POWER UP
Indicates that the voltage on CDM connector P38, pin 26 is too
low or the ground connections are loose; could be a wiring issue
E12
WCM POWER UP
E12 indicates that the voltage on WCM connector P34, pin 2 is
too low or the ground on pin 9 is loose; could be a wiring issue
E13 FUEL SOLENOID
WCM fuel solenoid output fault detected
E14
——
E15 KNIFE DRIVE PWM P68
Knife drive – PWM solenoid P68 drive fault detected
E16 DRAPER DRIVE PWM P69
Draper drive – PWM solenoid P69 drive fault detected
E17 REEL DRIVE PWM P70
Reel drive – PWM solenoid P70 drive fault detected
E18
——
E19 E119
Load Sense P75 Disc block valve – Solenoid P75 drive fault detected
E20
——
E21 E121
REVERSER P106
Reverser solenoid P106 fault detected
E22
——
E23 E123 REVERSER
Reverser – solenoid (P65, P66, P67) fault detected
E24 E124
DECK SHFT RIGHT P95
Right deck shift solenoid P95 fault detected
E25 E125 DECK SHFT LEFT P96
Left deck shift solenoid P96 fault detected
E26 E126 DWA UP
DWA raise solenoid P72, P73 fault detected
E27 E127
DWA DOWN
DWA lower solenoid P72, P73, fault detected circuit
