Description:

This error code, SCO 520529.31, indicates that the voltage ratio between Channel 1 and Channel 2 of the loader boom position sensor is not correct. The signal voltage of sensor 2 should be half of the signal voltage of sensor 1, but the difference is 0.4 volts or more.

Reaction:

When this fault is detected, the return-to-position function is limited.

Recommendations:

• Inspect Sensor Connections:
  • Check the connections of the loader boom position sensor for any signs of damage, looseness, or corrosion. Repair or replace any damaged connections.
• Verify Sensor Operation:
  • Ensure that both sensors in the loader boom position sensor are functioning correctly. Replace the sensor if necessary.
• Check Calibration:
  • Recalibrate the loader boom position sensor to ensure accurate readings from both channels.
• Consult Technical Support:
  • If the issue persists, consult technical support for further diagnostics and assistance.

Note:

Regular Maintenance:

• Regularly inspect and maintain the loader boom position sensors to ensure proper operation and prevent faults.
