CURTIS CONTROLLER DIAGNOSTICS:
Diagnostics Method A:
Uses the machine’s control display LED panel and detergent (EDS) system switch indicator.
FUNCTION OF THE SPEED CONTROLLER STATUS LIGHT AND DISPLAY
The Curtis 1243- (36V) speed control will output a fault code if there is a problem associated with the speed control and wheel drive system. See
Figure 8.7.
If a
speed control fault occurs, the display LED panel
(K)
on all models will indicate 03. When the 03 error code is displayed and detects a fault the Blue Indicator
(J)
normally the detergent (EDS) system indicator light will
fl
ash a special error code sequence until the fault is corrected. See “TABLE 1” for a description of the fault
indications. Service Note: Instructions on how to read the error code status light. Example, OO O = two light
fl
ashes, a short pause. One
fl
ash, long pause and the
code will be repeated. This indicates a fault code 2,1.
Diagnostics Method B:
Uses the optional hand held Curtis programmer model 1307 or the new model 1311 MP1101.
PROGRAMMER DIAGNOSTICS:
With a programmer, diagnostics and troubleshooting is more direct than with the LED alone. The programmer presents complete diagnostic information in plain
language, no codes to decipher. Faults are displayed in the Diagnostic Menu, and the status of the controller inputs/outputs is displayed in the Test Menu.
The following 4-step process is generally used for diagnosing and troubleshooting an inoperative vehicle: (1) visually inspect the vehicle for obvious problems; (2)
diagnose the problem, using the programmer; (3) test the circuitry with the programmer: and (4) correct the problem. Repeat the last three steps as necessary until
the vehicle is operational.
Example: A vehicle that does not operate in “forward” is brought in for repair.
1
Examine the vehicle and its wiring for any obvious problems, such as broken wires or loose connections.
2
Connect the programmer, put it in diagnostic mode, and read the displayed fault information. In this example, the display shows “No Faults Present”, indicating
that the controller has not detected anything out of the norm.
3
Put the programmer in test mode, and observe the status of inputs and outputs in the forward direction. In this example, the display shows that the forward
input did not activate when “forward” was selected, which means the problem is either in the electronic throttle or the throttle wiring.
4
Check or replace the electronic throttle and wiring and repeat the test. If the programmer shows the forward switch closing and the vehicle now drives normally,
the problem has been corrected.
Refer to the Status Fault Codes
(TABLE 1)
for suggestions covering a wide range of possible faults.
DIAGNOSTIC HISTORY
The handheld programmer can be used to access the controller’s diagnostic history
fi
le. Connect the programmer, press the MORE INFO key, and then while
continuing to hold the MORE INFO key, press the DIAGNOSTICS key. The programmer will read out all the faults that the controller has experienced since the last
time the diagnostic history
fi
le was cleared. The faults may be intermittent faults, faults caused by loose wires, or faults caused by operator errors. Faults such as
HPD or over temperature may be caused by operator habits or by overloading.
After a problem has been diagnosed and corrected, clearing the diagnostic history
fi
le is advisable. This allows the controller to accumulate a new
fi
le of faults. By
checking the new diagnostic history
fi
le at a later date, you can readily determine whether the problem was indeed completely
fi
xed.
To clear the diagnostic history
fi
le, go to the Special Program Menu (by pressing and holding the MORE INFO key, and then pressing the PROGRAM key), scroll
through the menu until “Clear Diagnostic History” is the top line in the display, and then press MORE INFO again. The programmer will prompt you to acknowledge
or cancel.
See the Curtis programmer manual 56043101 for more detail on programmer operation.

New text note:
The text used above in the descriptions of the Curtis programmer usage is that used for the original (older) model 1307. The manual 56043101 can be referenced
for the correct usage terminology for the new model programmer 1311.
