BRC 522279.05 – Low Current in Secondary Brake Control Valve. John Deere System Advisory.

BRC 522279.05 (BRC )

Code: 522279.05

Shortcode:

Description:

Error code BRC 522279.05 indicates that the current flowing to the secondary brake control valve is too low. This situation suggests an electrical issue within the braking system, possibly due to inadequate wiring, poor connections, or a malfunctioning valve that is not receiving sufficient power to operate correctly.

Reaction:

The control unit has responded to this low current issue by disabling the function of the secondary brake control valve, effectively turning it OFF. This action is taken to prevent any unpredictable behavior or failure in the brake system that could compromise vehicle safety.

Recommendations:

  • Inspect Electrical Connections: Check all wiring and connections associated with the secondary brake control valve for looseness, corrosion, or damage. Repair or replace any defective components.
  • Test Valve Current: Use a multimeter to measure the current at the valve to verify if it is within the specified range. Low readings indicate a problem in the power supply or the valve itself.
  • Replace Faulty Valve: If the valve is found to be faulty and not operating even with correct current levels, replace it to ensure reliable operation.
  • Check Control Unit Outputs: Ensure that the control unit is providing the correct output to the valve. Faults within the control unit could lead to low current issues.
  • System Reset and Testing: After repairs are made, reset the braking system and test thoroughly to ensure the secondary brake control valve is functioning properly with adequate current.

Note:

It is crucial for safety that all components of the braking system, including the secondary brake control valve, receive the correct electrical current to function as designed. Regular inspections and prompt repair of electrical issues are essential in maintaining the reliability and safety of the vehicle’s braking system.
