17. Loose or broken wire #08A from Joystick Enable
switch S7-6 to Control Module CM1 pin #P3-12.
(enable signal)
Check continuity. Test for 24V Input voltage
between wire #08A and wire #00.
Use HMI Diagnostic menu to make sure input P3-12
signal is present.
Replace if defective.
18. Loose or broken wire #23 from Joystick S7-2
to Control Module CM1 pin #P3-8. (steer right
signal)
Check continuity. Test for 24V Input voltage
between wire #23 and wire #00.
Use HMI Diagnostic menu to make sure input P3-8
signal is present.
Replace if defective.
19. Loose or broken wire #24 from Joystick S7-3 to
Control Module CM1 pin #P3-9. (steer left signal)
Check continuity. Test for 24V Input voltage
between wire #24 and wire #00.
Use HMI Diagnostic menu to make sure input P3-9
signal is present.
Replace if defective.
20. Defective Joystick S7 PCB.
Check joystick.
Replace joystick if defective.
21. Loose or broken wire #00B from Control Module
CM1 pin #P1-3 to joystick S7 (0V reference
signal)
Check continuity. Replace if defective.
22. Loose or broken wire #59 from Joystick S7 to
Control Module CM1 pin #P1-2. (analog output
signal)
Check continuity. Use HMI Diagnostic menu to
make sure proportional input P1-2 signal is present.
Replace if defective.
23. Loose or broken wire #08B from Joystick S7 to
Control Module CM1 pin #P1-1. (5V input signal)
Check continuity. Replace if defective.
24. External or internal fault detected by Control
Module CM1
Check Control Module display screen. Use
Diagnostic Menu to see switch and sensor status.
Correct trouble code as displayed. Replace module
