HAWKEYE™ NOZZLE CONTROL AND SIDEKICK PRO ICD SETUP
CONTROLLER DIAGNOSTICS INFORMATION TAB
The controller diagnostics tab provides status information for the Hawkeye ECU and may be helpful when
troubleshooting the system. To access Hawkeye system Diagnostic Information:
1. Open the VT Menu and select the Hawkeye Menu button.
2. From the home screen, select the Tools Menu softkey along the right side of the display.
3. Select the Diagnostics Info tab along the top of the display. The following controller information will be
displayed:
HC Voltage. The voltage for the high current bus circuit. High current power is provided system components to
actuate control features such as opening valves or nozzles.
Logic Voltage. Internal ECU voltage used for processing application data and rate control commands. The logic
voltage value should display 4.6V or higher for normal operation of the Hawkeye ECU and the Hawkeye nozzle
control system.
Pump Duty Cycle. Displays on the Diagnostics Info prompt. Use this value to monitor the current carrier pump
output percentage.
Flow Pulses. Displays flow pulses received from the system flowmeter. This value should be above zero when
product is flowing through the flowmeter.
ECU Yaw Rate. Represents the physical orientation of the Hawkeye ECU.
Pressure Signal. Displays pressure signal as a voltage from the pressure transducer. The value should be not be
zero when the boom is pressurized.
ISO CAN Errors. This value counts the number of CAN errors the system has encountered on the primary ISO
CAN bus.
NCV CAN Errors. This value counts the number of CAN errors the system has encountered on the NCV CAN bus.
Orientation. Displays the orientation number of the node pointing down. This number is used to calibrate the
system gyro for turn compensation.
DTC List. The diagnostic trouble code (DTC) list provides a list of recent errors for the equipment operator. Access
the DTC list to review previous error conditions, as well as a tally of each condition, during operation of the
Hawkeye nozzle control system.
Refer to Chapter 8, Troubleshooting, for additional assistance with diagnostic trouble codes and using the DTC
list.
