10.5 | IMU & Terrain Compensation Issues

Issue 
 Possible Cause 
 Recommended Action 
 
 
 
 
 Cross-slope compensation not operating correctly 
 IMU disconnected 
 Verify IMU harness connections and power supply 
 
 
 Cross-slope compensation not operating correctly 
 IMU not enabled within Level COMMAND 
 Verify IMU functionality is enabled within Level COMMAND 
 
 
 Cross-slope control produces unexpected movement 
 Incorrect IMU orientation 
 Verify IMU orientation and mounting direction 
 
 
 Implement is not level while reporting 0° / 0% cross-slope 
 IMU mounted on angled surface 
 Mount IMU to a level reference surface aligned with the machine 
 
 
 Implement is not level while reporting 0° / 0% cross-slope 
 Incorrect sensor offsets configured 
 Verify sensor offsets are correctly measured and configured within Level COMMAND 
 
 
 Cross-slope angle displayed incorrectly 
 Incorrect IMU assignment or configuration 
 Verify the correct IMU source is configured within Level COMMAND 
 
 
 Reported cross-slope angle is unstable 
 Loose IMU mounting hardware 
 Verify IMU mounting hardware is secure 
 
 
 Reported cross-slope angle is unstable 
 IMU mounted on flexible surface 
 Mount IMU to a rigid surface isolated from excessive vibration 
 
 
 Reported cross-slope angle is erratic even when travelling over smooth ground 
 Excessive vibration at mounting location 
 Inspect IMU mounting location and machine vibration sources 
 
 
 Cross-slope compensation differs between passes 
 IMU mounting position shifted 
 Inspect IMU mounting and alignment 
 
 
 Cross-slope compensation differs between passes 
 GNSS correction quality unstable 
 Verify RTK/DGNSS correction status 
 
 
 Cross-slope compensation produces inconsistent results 
 Sensor offsets disabled 
 Verify sensor offsets are enabled within Level COMMAND 
 
 
 TCM calibration cannot be completed 
 Poor satellite visibility 
 Move machine to open sky area clear of obstructions 
 
 
 TCM calibration cannot be completed 
 Incorrect GNSS receiver configuration 
 Verify GNSS receiver operation and correction quality 
 
 
 TCM calibration cannot be completed 
 Excessive machine vibration during calibration 
 Perform calibration with machine stationary and hydraulics stable 
 
 
 IMU intermittently disconnects 
 Loose connector or damaged harness 
 Inspect IMU harnessing and connectors 
 
 
 IMU intermittently disconnects 
 CANBUS communication instability 
 Verify CANBUS network integrity and termination 
 
 
 Terrain compensation differs between passes 
 IMU mounting shifted 
 Inspect IMU mounting and alignment 
 
 
 Terrain compensation differs between passes 
 GNSS correction quality unstable 
 Verify RTK/DGNSS correction status 
 
 
 Automatic Control performance inconsistent on slopes 
 Cross-slope compensation disabled 
 Verify terrain compensation is enabled within Level COMMAND 
 
 
 Automatic Control performance inconsistent on slopes 
 Incorrect terrain compensation source selected 
 Verify the intended IMU/TCM source is configured 
 
 
 TCM calibration cannot be completed 
 Poor satellite visibility 
 Move machine to open sky area clear of obstructions 
 
 
 TCM calibration cannot be completed 
 Incorrect GNSS receiver configuration 
 Verify GNSS receiver operation and correction quality 
 
 
 TCM calibration cannot be completed 
 Excessive machine vibration during calibration 
 Perform calibration with machine stationary and hydraulics stable 
 
 
 IMU intermittently disconnects 
 Loose connector or damaged harness 
 Inspect IMU harnessing and connectors 
 
 
 IMU intermittently disconnects 
 CANBUS communication instability 
 Verify CANBUS network integrity and termination
