STEERING COMPONENTS
This Steering Components screens allows user to
view real time sensor reading to verify they are
working, adjust sensitivity to some components,
and test reaction of other components. These
screens are used to test and manage all
components related to system’s interaction with
vehicle. List of components will vary depending
on activated vehicle profile.
To access Steering Components screen, press
Steering Components button from AutoSteer
Setup Vehicle screen.
GCU
GeoSteer Control Unit (GCU) is interface
between Control Unit and all sensors and
actuators on vehicle. The GSU receives
information from all sensors such as Angle
Sensor, pressure transducer, steering encoder, etc. and sends electrical signals to hydraulic valve.
GCU screen provides following information:
Firmware Version
—Version of software loaded on ECU.
Vehicle Type
— Vehicle type ECU is configured for, important to know to ensure ECU is configured properly to
communicate to vehicle type selected.
Bootloader Version
—Version of software that is loaded on ECU to allow it to boot up
Serial Number
—Serial Number of internal ECU.
Manual Steering Override
—A green light indicates AutoSteer system is detecting steering wheel motion or flow at flow
switch. A red light indicates no motion or flow is detected.
Communication
—If this light is green, system is communicating with ECU. If this light is not green, there is a problem
with the Control Unit.
MANUAL STEERING OVERRIDE
Manual Steering Override refers to sensor that is used to detect when operator manually turns steering wheel. AutoSteer
system needs to know when to stop AutoSteering when driver wants to take over steering manually. AutoSteer system can
detect this by getting a signal from a pressure transducer, flow switch, steering encoder, electrical resistance, or other
method. Manual Steering Override screen shows status of that sensor and allows user to adjust sensitivity of sensor.
Screen depends on vehicle profile detected. Refer to section that corresponds to sensor used for vehicle profile being used.

“Manual Steering Override” on page 15

NOTE!: It is important for Manual Steering Override to be functioning and set to proper level to allow user to
disengage AutoSteer manually. Never operate an AutoSteer system without this feature working or set properly.
Pressure Transducer
This screen is displayed for vehicle profiles that use a pressure transducer on Steering Valve. It allows user to verify sensor
is working and to adjust sensitivity of kick out to match user preferences. These screens are described in detail in Standard
Setup Wizard Steps section of this manual. See
“Pressure Transducer” on page 16
Steering Encoder and Flow Switch
Some vehicle profiles use an encoder on steering wheel or a flow switch in steering hydraulic lines to detect motion at
steering wheel. Encoder will send a signal when steering wheel is turned by user. Flow sensor will close circuit when it
detects oil flow through hydraulic line. For a flow switch, there are only two states, on and off so there is no adjustment
