Trouble shootings

MAC™ N series Auto Steering System Troubleshooting:

1: Tablet displays poor signal quality (Float/Pseudorange Solution).
Potential Causes:

• Excessive distance from base station
• Environmental obstructions blocking signals
• Poor satellite geometry or single-frequency reception
• High ionospheric activity

Solutions:

• Connect to a closer base station
• Upgrade GNSS receiver module
• Check SNR values for interference sources; replace tablet if using single-frequency GNSS

2: Tablet reports “Attitude Sensor Disconnected”, gyro data stream interrupted.
Potential Causes:

• Gyroscope hardware failure
• Wiring harness issues

Solutions:

• Sequentially test/replace: gyro sensor → main cable → control tablet

3: Starting with the steering wheel at full lock, when 'Start' is pressed, the steering wheel immediately turns fully in one direction.

Potential Causes:

• Left/right antennas reversed (vehicle model moves backward when driving forward)
• Motor controller firmware issue
• Improperly mounted/unstable attitude sensor

Solutions:

• Swap left/right antenna connections
• Update motor firmware
• Re-secure attitude sensor horizontally

4: Unstable forward deviation; error shifts left and right unpredictably, exceeding 3 in both directions during autonomous operation.

Potential Causes:

• Challenging terrain conditions
• Incorrect vehicle calibration
• Steering wheel play/hydraulic pressure loss
• Unstable attitude sensor mounting

Solutions:

• Unavoidable in poor terrain
• Recalibrate vehicle parameters
• Top up hydraulic fluid/service steering system
• Re-mount attitude sensor securely

5: Tractor consistently drifts to one side during autonomous forward operation.
Potential Causes:

• Inaccurate azimuth offset value
• Misaligned center angle in angle-sensor mode

Solutions:

• Recalibrate azimuth offset
• Adjust center angle calibration

6: Steering oscillation during reverse: Error increases slowly or steering swings left-right continuously.

Potential Causes:

• Excessive steering wheel play/hydraulic leakage
• Insufficient forward-looking distance setting
• Incorrect vehicle parameters

Solutions:

• Service steering system/hydraulics
• Increase forward-looking distance parameter
• Correct vehicle configuration

7: Uneven row spacing with inconsistent overlap (one side wider than the other).
Potential Causes:

• Implement hitch misalignment (when total overlap equals double target spacing)
• Unstable total implement width ≠ 2x target spacing

Solutions:

• Manually adjust implement toward wider side by 1/4 of spacing difference
• Use manual offset adjustment if implement can't be moved
• Check and secure implement hitch points 

8: Consistent but Incorrect row apacing (uniformly too qide or narrow).
Potential Cause:

• Incorrect implement width setting

Solution:

• Remeasure and reconfigure actual implement width

9: Uneven row spacing with incorrect total working width.
Potential Cause:

• Combined implement width error and possible hitch misalignment

Solution:

• First correct total implement width setting
• Then recalibrate individual row overlap values
