ADDITIONAL ERROR CODE TROUBLESHOOTING INFORMATION
When entering the main controller error fault recall mode and a fault Err01 or Err02 has been detected, the service person may see a second set
of error codes. Refer to the chart below that shows the additional fault error codes by machine system.
These secondary codes give information on a specific failure that is internal on the control board circuit. Therefore it is important to follow through
with all troubleshooting actions of any system faults that support an internal controller circuit failure before replacing a new main control board.
Example: A shorted solution solenoid valve causes a control fault 01 or 02 which appears on the machine’s hour meter / status display. The service
person brings up the fault recall memory and sees additional two-digit number(s) as shown in error code range in the chart below. A complete
check of that fault area would be completed before installing a new main control board.

MISCELLANEOUS ELECTRICAL SYSTEM TROUBLESHOOTING HORN CIRCUIT
•
If the horn doesn’t work check for 36V at horn wires. The horn (H3) is mounted under the right front of the machine frame (just below the
operator’s foot pedal).
•
If 0 volts, check for a failure (open) of the 2 Amp fuse F7 located on the main control assemble (A3).
IMPORTANT SERVICE TIP
When troubleshooting the electrical system with a displayed error code also enter the Service Test Mode Program to help diagnosis and confirm
a specific failure.
