Auto Calibrate
Operator’s Manual 57
To start the Tilt Zero Initial Direction calibration, drive the vehicle onto a flat surface and put in park or set the park brake.
Press the Resume button and wait for the system to finish the step. When this step is complete, the calibration process will
automatically move on to the next step.
Tilt Zero Opposite Direction
This is the second stage of this calibration procedure.
Note: It is important that the vehicle is positioned in the exact same place as the previous step but facing in the opposite
direction. If the vehicle is not placed in the same position, the tilt compensation will be incorrectly calculated and vehicle
steering performance will be degraded.
Figure 2-55 Tilt Zero Opposite Direction Calibration
To finish the Tilt Calibration, turn the vehicle around and park in the exact same location so that the rear tires are now over the
marks of the front tires (center of the track is at the same point but in the opposite direction). Press the Resume button and wait
for system to finish measuring.
The system will then automatically jump to the next step. This is the end of the Common Calibration Steps.
Vehicle Type Specific Calibration Steps
Depending on the vehicle type, the Auto Calibrate wizard will move to one of three different procedures to calibrate the
remaining sensors. Follow the procedure for the vehicle type that the system is being installed on.
Valve / Steer-by-Wire
This vehicle type has a steering valve that is controlled directly by the GeoSteer system. This includes vehicles that use the
standard AutoSteer valves, AutoTrac Ready (non ISO), AccuGuide Ready, and IntelliSteer, and some others. There are three
steps to finish the calibration process.
• Valve Deadband – This step determines the valve’s deadband which is the minimum signal that must be sent to start oil
flow.
• Angle Sensor – This calibrates the Angle Sensor on the steering axle.
• Valve – This calibrates the hydraulic valve.
The next step of the calibration process should have started automatically from the Common Calibration Steps.
Note: Verify that the engine RPM is at the working speed while this part of the calibration is taking place.
