Steering Components
Operator’s Manual 71
The ECU Sensors screen provides the user the raw data that the ECU is measuring. The ECU has a three axes Accelerometer,
three axes Gyro, and three axes Compass. These sensors allow the GeoSteer Control Unit to determine the Heading, Roll, and
Pitch of the unit.
CAN
If the GeoSteer system is installed on a vehicle that is interfaced via the CAN Bus or ISO Connection, the CAN screen will
display in the Steering Components screens. The CAN screen will provide specific information about the communication status
between the vehicle and GeoSteer system.
Note: The options displayed in the CAN screens will be different depending on the vehicle profile that the system is installed
on. Not all CAN Bus / ISO Controlled vehicles provide the same information.

Some of the options that can be displayed in the CAN screen are as follows:
• Wheel Angle or Curvature – For CAN vehicles, this is the estimated Curvature or a calculation based on it that the
vehicle sends to the GeoSteer Unit. This value should change as the steering wheel on the vehicle is manually turned.
• Roading Mode – Some vehicles have a lock out switch that prevents CAN Steering when the vehicle is on the road. If this
switch is enabled, the display will show: Enabled.
• Steering Wheel – If the system detects motion of the steering wheel, this will change to Motion Detected.
• Gear – If the vehicle provides transmission information, this will display if the vehicle is in forward, reverse, neutral, or
park.
• Comm – This provides an indicator if the communications are working. If they are not the display will show: Not Ok.
• Vehicle Status – Some vehicles need an indicator that there is a human in the machine, this is determined by the user
turning the steering wheel manually. If the system is waiting for the user to indicate their presence, the display will show:
Not Ready.
• Clutch – Some vehicles provide a status message of the clutch position.
• AutoSteer Status – This shows if the system is ready to AutoSteer. If it is not the display will show: Not Ready.
• Communication – If the vehicle is communicating with the CAN Bus or ISO Bus of the vehicle, this light will be green.
Actuator
The Actuator screen is used to verify that the vehicle can send commands through the CAN Bus or ISO Controller to steer the
vehicle. It is similar to the Steering Valve but the commands are not the same.
