Fault Descriptions CONTROLLER DIAGNOSTIC TOOL (CDT)
FAULT DESCRIPTIONS
The following faults can be detected by the IQ Plus controller and seen under both the Monitor Menu and Diagnostics
Menu :
01 THROTTLE FAULT 1
If the MCOR (Motor Controller Output Regulator) voltage is less than 0.20 volts or greater than 4.80 volts, the
controller detects a
throttle fault .
02 LOW BATTERY VOLTAGE
If the battery voltage falls below 34 volts (±5%), the low battery voltage fault is detected by the speed controller.
03 OVERVOLTAGE
If the speed controller detects that the battery voltage is too high (72 volts (±5%)), the overvoltage fault is detected.
04 THERMAL CUTBACK
If the controller heatsink temperature is found to be in excess of 85 °C (±5) (185 °F (±9)) or below –25 °C (±5) (–13 °F
(±9)), the
thermal cutback fault is detected.
06 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, when not caused by the operator, can indicate that the pedal limit switch has
failed closed.
07 MAIN WELDED
If the speed controller detects that the solenoid contacts are welded closed, a main welded fault is detected.
08 RELAY WELDED
If the speed controller detects that the external Walk Away relay contacts are welded closed, a relay welded fault
is detected.
09 SPEED SENSOR
If the speed controller does not detect pulses from the speed sensor while the controller outputs power (greater than
75% armature PWM) to the motor, a
speed sensor fault is detected.
10 MAIN DRIVER ON
If the FET that controls the activation of the solenoid coil is found to be energized when it should not be, a main driver
on fault is detected by the speed controller.
11 MAIN COIL OPEN
If the Main Contactor Coil develops an open circuit or is disconnected from the controller , a main coil open fault is
detected. Walk Away is not affected by this fault.
