IQ DISPLAY MODULE (IQDM) AND IQDM-P
DIAGNOSTICS: IQ SYSTEM

FIELD MISSING

If the speed controller is operating at a duty cycle of greater than 90% (almost full speed) and the field current is less
than 3 amps, a field missing fault is detected by the speed controller.

HPD

The HPD (High Pedal Detect) fault is detected if the accelerator pedal is already depressed when the key switch is
turned to the ON position. This fault is also detected if the accelerator pedal is pressed when the selected direction
is changed by pressing the Forward/Reverse switch. This fault, when not caused by the operator, can indicate
that the pedal limit switch has failed closed.

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.

OVERVOLTAGE

If the speed controller detects that the battery voltage is too high (68.4 to 75.6 volts DC), the overvoltage fault
is detected.

LOW BATTERY VOLTAGE

If the battery voltage falls below 34 volts ±5%, the low battery voltage fault is detected by the speed controller.

THERMAL CUTBACK

If the controller heatsink temperature is found to be in excess of 85 °C ±5 °C (185 °F ±9 °F) or below –25 °C ±5 °C
(–13 °F ±9 °F), the thermal cutback fault is detected.

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 dropout fault
is detected.
