CSC 523973.18 – Bleeding (Cab Suspension), Level Position Not Reached. John Deere System Advisory.

CSC 523973.18 (CSC )

Code: 523973.18



Error code CSC 523973.18 is triggered when the cab suspension fails to reach the middle position during the bleeding process within the directed time. This indicates an issue in achieving the correct level position, which is crucial for proper suspension operation.


  • Bleeding process fails, and the procedure must be restarted.


  • Repeat Bleeding Procedure: Follow the recommended procedure to bleed the cab suspension system again, ensuring all steps are correctly followed.
  • Inspect Hydraulic System: Check the hydraulic system for leaks, blockages, or any issues that could prevent the cab from reaching the middle position. Repair or replace any faulty components.
  • Evaluate Solenoid Valves: Test the solenoid valves responsible for raising and lowering the cab. Ensure they are functioning properly and are correctly connected.
  • Verify Sensor Functionality: Ensure the cab suspension sensors are providing accurate readings. Replace any sensors that are faulty or out of calibration.
  • Check for Air in Hydraulic Lines: Ensure that all air is properly bled from the hydraulic lines, as air pockets can prevent the cab from reaching the correct position.
  • Perform System Calibration: After successfully bleeding the system, perform a full calibration to ensure the cab suspension operates correctly.


Proper bleeding and calibration of the cab suspension are essential for maintaining vehicle stability and operator comfort. Regular maintenance and careful attention during bleeding procedures help ensure reliable performance.
