BRC 523837.04 – Low Voltage in Rear Brake Pressure Sensor Circuit. John Deere System Advisory.

BRC 523837.04 (BRC )

Code: 523837.04

Shortcode:

Description:

Error code BRC 523837.04 occurs when the voltage at the rear brake pressure sensor falls below 0.10 volts, a condition likely caused by a sensor malfunction, poor electrical connections, or a fault in the wiring or power supply. Such low voltage levels can result in inaccurate or non-existent pressure readings, potentially compromising brake system integrity.

Reaction:

The control unit has disabled the rear brake function in response to this low voltage reading to prevent unsafe braking behavior that could arise from incorrect sensor data.

Recommendations:

  • Inspect Sensor and Electrical Connections: Thoroughly check the rear brake pressure sensor and its connections for signs of corrosion, damage, or looseness that might be contributing to the low voltage.
  • Measure Voltage Output: Use a multimeter to verify the voltage output at the sensor. This step will help isolate the problem, whether it’s with the sensor or elsewhere in the electrical circuit.
  • Replace Faulty Sensor: If the sensor is found to be defective, replacing it is necessary to restore proper functionality to the brake system.
  • Examine Wiring and Circuitry: Evaluate all wiring and circuitry associated with the rear brake pressure sensor to ensure there are no breaks, shorts, or other electrical issues reducing voltage.
  • Calibrate and Test the System: After resolving the hardware issues, recalibrate the sensor to manufacturer specifications and perform comprehensive testing to ensure the system operates correctly under all conditions.

Note:

It is crucial to maintain the electrical integrity of sensors within the braking system to ensure they provide reliable data for safe operation. Regular monitoring and maintenance of these components can prevent problems associated with voltage anomalies and ensure the long-term reliability of the vehicle’s brake system.
