BCU 001058.18 – Information for Operator: Air Brake System Pressure Switch Not Activated. John Deere System Advisory.

BCU 001058.18 (BCU 1058.18)

Code: 001058.18

Shortcode: 1058.18

Description:

Error code BCU 001058.18 is triggered when the Basic Control Unit (BCU) of a John Deere vehicle identifies that the pressure switch for the air brake system has not been activated due to pressure being too low. This informational alert is generated following an incorrect entry at address BCU065, indicating potential issues with the system settings or the air brake system’s pressure levels.

Reaction:

The BCU uses this code to inform the operator of insufficient air pressure in the brake system, which is a critical safety concern. This condition can prevent the air brakes from functioning correctly, potentially leading to decreased vehicle control and increased risk of accidents.

Recommendations:

  • Check Air Brake System Pressure: Immediately inspect the air brake system to ensure it is pressurized correctly. Look for leaks, damaged lines, or faulty components that could be causing the pressure to drop below the required level.
  • Verify System Settings at BCU065: Review the settings at address BCU065 to ensure that they are correctly configured. Incorrect settings can lead to improper system responses or warnings.
  • Inspect Pressure Switch: Examine the pressure switch for functionality. Test the switch to ensure it activates at the correct pressure level and is not faulty.
  • Repair or Replace Faulty Components: Repair any leaks or replace damaged components in the air brake system. If the pressure switch is defective, replace it to ensure it accurately detects and responds to pressure changes.
  • Reset the BCU and Clear the Fault Code: After addressing the issues, reset the BCU to clear the fault code and reconfigure any incorrect settings. Test the system to ensure the air brake system operates correctly and the pressure switch activates as expected.
  • Conduct a Comprehensive System Test: Perform a thorough test of the air brake system under various operating conditions to ensure all repairs and adjustments are effective and the system maintains proper pressure.

Note:

Maintaining the air brake system in optimal working condition is crucial for the safety of vehicle operations. Regular monitoring and maintenance of the air pressure levels and associated switches can help prevent critical failures and ensure that the braking system functions reliably under all conditions. Addressing alerts about air brake pressure proactively is key to ensuring the safety and operational readiness of your John Deere equipment.
