Description:

This error code, XSC 000708.18, indicates that the frequency registered at channel 1 of the steering wheel position sensor is below 150 Hz. Despite this, the value measured by the XMC control software is within the acceptable range, suggesting a potential issue with the sensor or 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 Frequency:

• Use diagnostic tools to monitor the sensor frequency and verify if it is consistently below the expected range.
• Compare the sensor frequency 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 frequency readings and any steps already taken to address the fault.

Note:

Maintaining the proper frequency 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.
