IQ DISPLAY MODULE (IQDM) SERIES 2
AND IQDM-P DIAGNOSTICS
30 Relay Coil Fault
If the Walk Away relay develops an open circuit or is disconnected from the controller, a relay coil fault is detected.
Main CONT DNC
The main cont dnc (main contactor (solenoid) did not close) fault is detected when the speed controller has sent
voltage to the solenoid activating coil but the solenoid contacts are not closed.
Main Coil Fault
If the speed controller determines that the solenoid is not closing as a result of a solenoid coil failure, a main coil fault
is detected.
PROC/Wiring
This fault is detected if the Forward/Reverse switch is giving a signal to place the controller in forward and reverse at
the same time. This rare fault can be caused by a failed Forward/Reverse switch or improper vehicle wiring.
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 activate Mode 2. If a set of codes has been
entered incorrectly, the
incorrect password fault is declared. See also Password Tries (IQDM-P only) on page 23-6.
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. If the fault history is not cleared
after a repair, a technician may mistakenly replace a new component due to an old fault code. For example, if the
MCOR device 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.
See Clear
Fault History on page 23-19.
FUNCTIONS MENU
The functions menu is accessed by using the up or down arrow to scroll to functions and pressing the right arrow
key to activate the menu.
GET SETTINGS FROM CONTROLLER
This function transfers all of the speed controller settings (except for “private speed mode”) from the vehicle speed
controller to the handset. This enables the trained technician to “clone” a speed controller. Once the speed controller
settings have been transferred to the handset, the technician can then connect the handset to another vehicle and
transfer the stored settings into the speed controller.
