Description:

This error code, XSC 001807.21, is generated when the duty cycle at channel 1 of the steering wheel position sensor falls below 1%. This low duty cycle indicates a potential malfunction of the sensor or its signal processing.

Reaction:

When this fault occurs, the control software will exhibit limited or no functionality, impacting the accuracy and responsiveness of the steering system.

Recommendations:

Inspect Steering Wheel Position Sensor:

• Check the steering wheel position sensor for any signs of damage or wear.
• Ensure the sensor is properly installed and securely connected.

Monitor Sensor Duty Cycle:

• Use diagnostic tools to monitor the duty cycle of the sensor and verify if it consistently falls below the normal operating range.
• Compare the duty cycle readings with those from the XMC control software 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.
• Provide detailed logs of the sensor duty cycle readings and any steps already taken to address the fault.

Note:

Maintaining the proper duty cycle of the steering wheel position sensor is crucial for the accurate functioning of the steering system. Regular inspections and updates can help ensure system reliability.
