DIAGNOSTICS: IQ SYSTEM
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 on page 20-3. See also
Password Tries (IQDM-P only) on page 13-6.
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 on page 20-3. See
also Password Tries (IQDM-P only) on page 13-6.
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 throttle position sensor was disconnected 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.
