XSC 522451.02 – Wheel Angle Sensor, Voltages in Channel 1 and Channel 2 Not in Correct Ratio

XSC 522451.02 (XSC )

Code: 522451.02

Shortcode:

Description:

This error code, XSC 522451.02, indicates that the signal voltage ratio between the two separate sensors in the wheel angle sensor (WAS) is incorrect. Sensor 2’s signal voltage should be half of Sensor 1’s, but a difference of 0.4 volts or more has been detected.

Reaction:

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

Recommendations:

Inspect Wheel Angle Sensor:

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

Monitor Sensor Voltages:

  • Use diagnostic tools to monitor the voltages of both sensors in real-time.
  • Identify and correct any deviations from the expected 1:2 voltage ratio.

Check Wiring and Connections:

  • 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.

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 voltage readings and any steps already taken to address the fault.

Note:

Maintaining the correct voltage ratio between the sensors in the wheel angle sensor is essential for accurate steering system functionality. Regular inspections and updates can help ensure system reliability.
