FAULTS MENU

The faults menu is accessed by using the up or down arrow to scroll to faults and pressing the right arrow key
to activate the menu.
Faults displayed in the faults menu will aid the trained technician in troubleshooting the vehicle. Faults dis-
played often indicate which components in the electrical system need to be tested.
Since the faults menu is updated while the vehicle is in operation, the trained technician has the ability to mon-
itor the occurrence of faults in conditions or locations where a problem with vehicle performance has been
reported. See following Warning.

WARNING
• The vehicle operator should not monitor the handset while the vehicle is in motion. A
technician can monitor the handset while traveling as a passenger in the vehicle. Failure to
heed this warning could result in severe personal injury or death.

SYSTEM FAULTS

NOTE: The system faults menu displays all of the present faults detected by the speed controller. The
faults displayed in this menu are currently active. Once a fault has been detected, it is stored in the
memory of the speed controller for display on the fault history menu. Each detected fault is listed
only once in the fault history menu, the number of fault occurrances are located in the fault counter
section of the monitor menu, even if the fault has occurred multiple times.
Causes of Faults
Some common causes of faults are
• Loose, broken, or disconnected wires or connectors
• Failed components
• Improper adjustment or installation of electrical or mechanical components (examples: brake adjust-
ment, improper MCOR installation)
• Improper wiring of electrical components
As shown above, there are many possible causes for faults to occur, and the speed controller has a pro-
grammed reaction to each fault that is based on the fault currently detected. The technician should be familiar
with the detected faults and the controller's reactions to faults to ensure a proper diagnosis.
An example of a possible mis-diagnosis of a vehicle due to a fault: If the three-pin speed sensor wire has been
disconnected, the speed controller will detect a speed sensor fault. When a speed sensor fault is detected,
the controller responds to the fault by limiting the vehicle speed to 1/2 of its normal top speed. If the technician
reaches the conclusion that the vehicle is running slowly because batteries are heavily discharged, he has
made an improper diagnosis of the problem.
