Motor Stall
If the motor current is high and there is no movement of the vehicle wheels for a short period of time, a
motor
stall
is detected by the speed controller. This fault can be caused by an operator holding the vehicle on a hill
by depressing the accelerator pedal instead of the brake pedal.
Main Dropout
If the controller detects that the solenoid contacts have opened while the vehicle is in operation, a
main drop-
out
fault is detected.
Open Armature
If the accelerator pedal is pressed 2/3 to the floor, the armature current is less than 20 amps, and there are no
speed sensor pulses, an
open armature
fault is detected.
Incorrect Password (IQDM-P only)
Each vehicle has a password in the form of a unique set of codes used to place the vehicle in “private speed
mode”. If a set of codes has been entered incorrectly, the
incorrect password
fault is declared. For additional
information on codes, refer to Code A, Code B, and Code C.
See Code A, Code B, and Code C, Section 18,
See also Password Tries (IQDM-P only) on page 12-5.
Max Password Tries (IQDM-P only)
The
max password tries
fault is declared when the incorrect password fault has been declared several times.
In the event that the
max password tries
fault is indicated, the speed controller must be removed and shipped
to Club Car before it can ever be placed in “private speed mode”.
See Code A, Code B, and Code C,
See also Password Tries (IQDM-P only) on page 12-5.
Fault History
The
fault history
menu 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 vehicle operator error.
If a fault appears in the
fault history
menu, 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 accelerator 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.
All of the occurrance numbers located in the lower section of the monitor menu will be reset
to zero each time the fault history is cleared except for the High Speed WalkAway occurrance numbers.
