BRC 001079.04 – Low Sensor Supply Voltage in Brake Control Unit. John Deere System Advisory.

BRC 001079.04 (BRC 1079.04)

Code: 001079.04

Shortcode: 1079.04

Description:

The error code BRC 001079.04 indicates that the sensor supply voltage within the Brake Control Unit (BRC) for the Option Configuration Connector has dropped below the normal operational threshold of 4.55 volts. This low voltage can lead to inaccurate sensor readings and potentially compromise the correct functioning of the braking system.

Reaction:

Due to this voltage issue, the functionality of the Brake Control Unit has been degraded, which may affect the precision and reliability of the braking system operations.

Recommendations:

  • Check Voltage Supply Sources: Ensure that the battery and alternator (if applicable) are functioning properly and capable of supplying adequate voltage.
  • Inspect Wiring and Connections: Examine all wiring and connections leading to the BRC for signs of wear, corrosion, or looseness that might be causing voltage drops.
  • Test and Replace Faulty Components: Utilize a multimeter to test the voltage levels being supplied to the sensors. Replace any faulty voltage regulators or other components that might be responsible for the low voltage.
  • Calibrate the BRC: After ensuring that the voltage levels are restored, recalibrate the Brake Control Unit to accommodate the correct sensor inputs.
  • Regular Monitoring and Maintenance: Implement a regular maintenance schedule to monitor the voltage levels and general health of the BRC, ensuring it consistently operates within the correct voltage parameters.

Note:

It is crucial to maintain the designated sensor supply voltage for the proper operation of the Brake Control Unit. Fluctuations in voltage can significantly impair the functionality and safety of the braking system. Regular checks and prompt maintenance can prevent these issues, enhancing the reliability and safety of the vehicle.
