BRC 522280.04 – Low Voltage in Secondary Brake Pressure Sensor. John Deere System Advisory.

BRC 522280.04 (BRC )

Code: 522280.04

Shortcode:

Description:

Error code BRC 522280.04 is triggered when the voltage at the secondary brake pressure sensor falls below 0.10 volts. This unusually low voltage reading suggests potential issues such as a sensor malfunction, poor electrical connections, or a fault in the wiring or electrical circuitry supplying power to the sensor.

Reaction:

The low sensor voltage results in a degraded function of the braking system. This condition can significantly impair the accuracy of brake pressure measurements, potentially affecting the braking performance and safety of the vehicle.

Recommendations:

  • Inspect Sensor and Electrical Connections: Examine the secondary brake pressure sensor and its connections for signs of damage, corrosion, or looseness that might be causing low voltage readings.
  • Test Sensor Output: Utilize a multimeter or diagnostic tool to measure the sensor’s voltage output under various operating conditions to determine if the low voltage is consistent.
  • Replace Faulty Sensor: If the sensor is found to be defective, replace it to ensure it accurately monitors brake pressures.
  • Evaluate Vehicle’s Electrical System: Check the vehicle’s electrical system, focusing on the circuits connected to the brake sensor, for any issues that might be causing reduced voltage outputs.
  • Recalibrate and Test the System: After making necessary repairs or replacements, recalibrate the sensor according to the manufacturer’s specifications and perform a comprehensive test of the braking system to confirm it functions properly.

Note:

Regular maintenance and accurate calibration of brake pressure sensors are vital for the effective and safe operation of the braking system. Ensuring these components function correctly can prevent degradation of the system’s performance and maintain the vehicle’s safety standards.
