• Ensure the sensor is properly installed and securely connected.

Verify Steering Control Valves:

• Inspect the steering control valves for proper operation and ensure they receive commands correctly.
• Check for any blockages or malfunctions in the control valves.

Monitor Sensor Output:

• Use diagnostic tools to monitor the sensor output and verify if it correctly corresponds to steering commands.
• Compare sensor readings with actual steering movements to identify discrepancies.

Update Control Software:

• Check for and install any available updates for the control software to address potential bugs or signal processing issues.

Consult Technical Support:

• If the issue persists, contact John Deere technical support for further diagnostics and solutions.
