BRC 522280.03 – High Voltage in Secondary Brake Pressure Sensor. John Deere System Advisory.

BRC 522280.03 (BRC )

Code: 522280.03

Shortcode:

Description:

Error code BRC 522280.03 is triggered when the voltage at the secondary brake pressure sensor exceeds 4.50 volts, indicating an abnormal condition in the sensor output. This high voltage can be a sign of sensor malfunction, electrical interference, or a fault in the wiring or circuitry providing power to the sensor.

Reaction:

The high sensor voltage leads to degraded functionality of the braking system. This condition can affect the accuracy of brake pressure readings and potentially compromise the braking effectiveness and safety of the vehicle.

Recommendations:

  • Inspect Sensor and Wiring: Check the secondary brake pressure sensor and its associated wiring for signs of damage, corrosion, or loose connections that might be causing abnormal voltage readings.
  • Test Sensor Output: Use a multimeter or a diagnostic tool to test the sensor output under various operating conditions to verify if the high voltage persists or fluctuates.
  • Replace Faulty Sensor: If the sensor is found to be defective, replace it to ensure accurate monitoring of brake pressures.
  • Review Electrical System: Examine the vehicle’s electrical system, particularly the circuits connected to the brake sensor, for any issues that might be causing excessive voltage outputs.
  • Calibrate and Test the System: After addressing the hardware issues, recalibrate the sensor to the manufacturer’s specifications and conduct a thorough test of the braking system to ensure it is functioning correctly.

Note:

Maintaining the integrity and accuracy of brake pressure sensors is crucial for the reliable operation of the braking system. Regular inspections and timely replacement or calibration of sensors can prevent problems that might lead to degraded system performance and ensure the safety of vehicle operations.
