CSC 523973.15 – Sensor for Cab Suspension at Bottom Stop, Incorrect Sensor Signal. John Deere System Advisory.

CSC 523973.15 (CSC )

Code: 523973.15



Error code CSC 523973.15 occurs when, during calibration, the cab suspension position sensor’s voltage does not fall below 2 V when the cab is fully lowered. This indicates an incorrect sensor signal, leading to calibration failure.


  • Calibration is aborted.
  • Limited function of the vehicle.


  • Inspect Sensor and Connections: Examine the cab suspension sensor and its wiring for any signs of damage or loose connections. Repair or replace as necessary.
  • Measure Sensor Voltage: Use a voltmeter to measure the voltage at the cab suspension sensor when the cab is fully lowered to ensure it falls below 2 V.
  • Replace Faulty Sensors: If the sensor is faulty and does not provide correct signals, replace it.
  • Recalibrate Sensor: Perform a recalibration of the cab suspension system to ensure accurate sensor readings and proper calibration.
  • Review Control Software Settings: Ensure the control software is correctly configured to process the sensor signals during calibration.
  • Conduct Comprehensive System Tests: After repairs, reset the system and perform thorough tests to confirm that the sensor operates correctly and the cab suspension calibrates successfully.


Accurate sensor signals are vital for the proper calibration and operation of the cab suspension system. Regular inspections and timely repairs help maintain the system’s reliability and performance.
