M– SHORTED
If an uncontrolled current path is detected from the motor to B- (bypassing the MOSFETs), an M- shorted fault
is detected.

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 MCOR3 (Motor Controller Output Regulator 3) 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 11-19.

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.
Speed Controller Cloning – Transferring Settings from the Vehicle to the Handset
1. Locate a vehicle that has the desired speed controller settings.
2. Turn the key switch to the OFF position, place the Forward/Reverse handle in the NEUTRAL position, and
lock the park brake.
3. Plug the handset into the vehicle.
3.1. Connect one end of the cable to the port located on the bottom of the handset.
3.2. Connect the cable adaptor to the IQDM cable.
3.3. Remove the dust cap from the IQDM port.
3.4. Align the keyed portion of the plug with the IQDM port and connect the plug to the port (Figure 11-1,
Page 11-1).
