Troubleshooting Tips
1. Implement receiver not showing up in the GreenStar
Display
Check if Constant Power Extension harness
(PF90550 or PF90551) is installed.
Check for latest software (version 2.3.1385 or
higher) on Implement Receiver.
Check if receiver is receiving Switched, Unswitched,
CAN Low and CAN High power.
Check machine fuse panel for blown fuses
2. Implement GPS loses RTK signal more often than
machine receiver
Check antenna on GPS receiver for tight
connection.
Verify receiver has good line of sight to the base
station.
Set machine to Vehicle Repeater. Only one
Repeater or Vehicle Repeater can be used for
selected base station ID.
3. Implement Error is not reduced in a reasonable
amount of time
Incorrect machine or implement offsets.
iGuide sensitivity is set too low.
Incorrect Slope compensation value.
Engage iGuide closer to desired path.
Adjust control point.
4. Machine or implement is “S’ing” around the line
iGuide sensitivity is too high.
Steer sensitivity is too high.
5. Guess rows having a reoccurring skip/overlap pattern
Calibrate TCM on implement and machine
receivers.
Change Implement GPS offsets.
Implement row units not properly spaced.
6. Reduced Accuracy
If possible, mount the implement receiver as
close as possible to the control point. Mounting
receiver too close to rear of machine may result
in less accurate performance. Mounting receiver
too far from control point may also cause poor
performance.
Control Point— location around which the
implement rotates. This is typically the axle of the
implement.
7. Adjusting the Control Point offset (examples)
If the implement consistently tracks inside curve,
increase control point offset.
If the implement consistently tracks outside curve,
decrease control point offset.
8. Slow to line acquisition and Sing when reentering
passes at headlands
Resume switch should be activated when making
the turn.
NOTE: Do not wait until implement is aligned to
push the resume switch as this may cause
Sing at the beginning of passes.
9. After unloading data in Apex and saving setup back
to the data card, iGuide produces wide and narrow
guess rows
Make sure the offsets saved in Apex are the same
as when you measured the vehicle, implement, and
implement receiver offsets.
If the offsets are the same, create a new machine
name, machine model, implement name, and
implement model. Then enter the measured offsets.
Recalibrate both TCMs (vehicle and implement).
For best results, calibrate the TCM on a flat surface.
NOTE: If the problem still exists, format or use a
new data card. Then enter the correct offsets
for the vehicle offset page, implement offset
page, and implement receiver offset page.
NOTE: If keeping the measured offsets, create
a unique vehicle and implement name to
store them under. If unique vehicle and
implement names are not used, GSDNet
updates will overwrite offsets.
10. iGuide is oversteering on flat ground (less than 2
degrees)
Verify Slope Compensation is off.
Lower iGuide Sensitivity.
11. iGuide respond for lateral implement draft is too slow
Verify Slope Compensation is on.
Recalibrate Slope Compensation.
Increment Slope Compensation value using the
increment button until the proper value is found.
Raise iGuide Sensitivity.
12. iGuide calculates a high value after Slope
Compensation Calibration
Check if iGuide was active during the calibration.
Check if calibration was performed on ground with
less than 2 degree of roll angle.
13. iGuide does not work properly with row crop cultivation
iGuide is not designed to work on row crop
cultivation.
14. Poor performance on articulated tractors
Verify if front axle has been selected as Non Steer
Axle and remeasure vehicle offsets.
15. Points to Remember
In iGuide mode, remember error on the display is
error at the implement. Error for iGuide may be
higher on the display than machine error was when
the system was in normal AutoTrac mode.
iGuide may not perform as well in tight turns or end
turns as it does on more gradual curves; especially
on severe slopes when the implement is sliding
down hill.
iGuide is a reactive system and can only respond to
implement errors.
System performance can be affected by several
factors on the machine and implement. Examples:
ballasting, tire inflation, hitch play, amount of
weight on the implement (seed, fertilizer, chemical),
second implement (air cart, tank), ground engaging
equipment in proper working order, and offsets,
values, and sensitivities in the GreenStar Display.
