FAULT HISTORY
The fault history can be useful in determining the cause of a vehicle problem; however, the fault history alone
should not be the factor that determines when a component is replaced. Some faults detected by the speed
controller are not the result of a failed component, and are instead the result of operator error. If a fault
appears in the fault history, the trained technician should attempt to determine when and where the fault has
occurred. For example, if the
motor stall
fault is present in the fault history, the trained technician may be able
to determine the location on the course where an operator has held the vehicle on a hill by using the acceler-
ator pedal.
CLEARING FAULT HISTORY
After a repair has been made, the fault history should be cleared. This will enable the trained technician to
properly troubleshoot the vehicle in the future, in the event that another problem occurs. It is recommended
that the fault history be cleared in order to avoid the replacement of a component that caused a fault in the
past, but has been replaced and is now functioning correctly. For example, if the MCOR device was discon-
nected and the speed controller detected a fault code associated with the throttle, the fault history should be
cleared so that any future problem is not diagnosed incorrectly as a throttle problem.

SPECIAL PROGRAM MENU
The Special Program menu is accessed by holding the MORE INFO button while pressing the program but-
ton. The Special Program menu enables the trained technician to perform many useful functions
(Figure 10)
.
The special program functions are selected in the same way that items are selected on other menus. When
the menu has been activated
(Figure 11)
, use the SCROLL DISPLAY buttons to select a function. The
selected function always appears on the
top line
of the display. Once a function has been selected, press the
MORE INFO button. If a function has been accidently selected, press the more info button to return to the
Special Program menu without making any changes. The display screen will indicate that no change was
made
