Description:

This error code, XSC 523789.05, is generated when the XSC control software registers that the voltage at the output of the wheel angle sensor is too high. This condition indicates that the circuit is open, suggesting a potential issue with the sensor or its wiring.

Reaction:

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

Recommendations:

Inspect Wheel Angle Sensor:

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

Check Wiring and Connectors:

• Inspect the wiring and connectors associated with the wheel angle sensor for any signs of damage, corrosion, or loose connections.
• Ensure all connections are secure and properly terminated.

Test Sensor Circuit:

• Use diagnostic tools to test the continuity and integrity of the sensor circuit.
• Identify and correct any open circuits or high resistance points.

Monitor Sensor Voltage:

• Use diagnostic tools to monitor the voltage levels at the sensor output in real-time.
• Identify and correct any deviations from the normal operating range.

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 circuit tests and any steps already taken to address the fault.

Note:

Ensuring the integrity of the wheel angle sensor circuit is crucial for the proper functioning of the steering system. Regular inspections and maintenance of the sensor circuits can help prevent such faults.
