BRC 001079.03 – High Sensor Supply Voltage in Brake Control Unit. John Deere System Advisory.

BRC 001079.03 (BRC 1079.03)

Code: 001079.03

Shortcode: 1079.03

Description:

The error code BRC 001079.03 indicates that the sensor supply voltage for the Option Configuration Connector in the Brake Control Unit (BRC) has exceeded the normal limit, measuring above 5.25 volts. This elevated voltage can potentially damage sensitive sensor equipment or cause incorrect sensor readings, leading to improper functioning of the brake system.

Reaction:

As a result of this high voltage, the function of the Brake Control Unit has been degraded. This means that while the brake system may still operate, its performance might not be optimal and could affect overall vehicle safety and control.

Recommendations:

  • Inspect Voltage Regulators: Check and ensure that all voltage regulators associated with the BRC are functioning correctly. Replace if any are found to be faulty.
  • Verify Connections and Wiring: Examine the connections and wiring to the Option Configuration Connector for any signs of damage, corrosion, or loose connections that might cause high voltage.
  • Monitor Voltage Levels: Use a multimeter to monitor the voltage levels being supplied to the sensors. Adjustments may need to be made to ensure that the voltage stays within safe parameters.
  • Reset and Recalibrate the BRC: After making any necessary repairs, reset and recalibrate the Brake Control Unit to ensure all system parameters are correctly set.
  • Continuous Monitoring: Implement a routine to continuously monitor sensor supply voltages as part of regular vehicle maintenance to catch and correct any deviations before they affect system functionality.

Note:

Maintaining proper voltage levels is critical for the accuracy and longevity of the sensors and related components in the Brake Control Unit. Regular maintenance and careful monitoring of these systems help prevent issues related to voltage irregularities, thus ensuring the safety and reliability of the vehicle’s braking system.
