BRC 522279.06 – High Current in Secondary Brake Control Valve. John Deere System Advisory.

BRC 522279.06 (BRC )

Code: 522279.06



Error code BRC 522279.06 is triggered when the current flowing to the secondary brake control valve exceeds the normal operational range, indicating an electrical overload. This could result from issues such as a short circuit, faulty wiring, or an incorrect setup that allows excessive current to reach the valve.


In response to this high current condition, the functionality of the secondary brake control valve has been disabled, turning it OFF. This preventive measure is aimed at avoiding potential damage to the valve or associated braking system components, which could lead to brake failure.


  • Inspect Wiring for Short Circuits: Carefully examine the wiring connected to the secondary brake control valve for any signs of short circuits or damage that could be causing the high current.
  • Test Electrical Components: Use electrical testing equipment to measure the current flow and identify any abnormalities in the circuit that may be contributing to the issue.
  • Replace or Repair Faulty Parts: If any components are found to be defective, such as a malfunctioning valve or damaged wires, replace or repair them immediately to prevent further issues.
  • Verify System Configuration: Check that all settings and configurations related to the secondary brake control valve are correct according to manufacturer specifications, to ensure no overcurrent settings are applied.
  • Reset and Re-Test the System: After making necessary repairs and adjustments, reset the braking system and conduct comprehensive tests to verify that the issue is resolved and the valve operates within the safe current range.


Maintaining the correct current levels to the secondary brake control valve is essential for safe braking operations. Regular monitoring and maintenance of the electrical system are critical to detect and address any issues early, ensuring the longevity and reliability of the braking system.
