CSC 523973.02 – Cab Position Out of Valid Range During Calibration. John Deere System Advisory.

CSC 523973.02 (CSC )

Code: 523973.02



Error code CSC 523973.02 is generated when the control software detects that the cab suspension sensor’s mid-position voltage is outside the valid range of 2 to 3 volts during calibration or bleeding and calibrating. This indicates that the cab position sensor is providing incorrect readings, which can impact the calibration process.


The calibration process is aborted to prevent incorrect calibration settings based on faulty sensor data.


  • Diagnose Related CSC Codes: If other CSC codes related to the cab suspension position sensor are present, diagnose and resolve those issues first.
  • Inspect Sensor Connections: Check the wiring and connections to the cab suspension sensor for any signs of damage, looseness, or disconnection.
  • Test Sensor Voltage: Use a voltmeter to measure the voltage at the cab suspension sensor and ensure it falls within the 2 to 3 volt range.
  • Replace Faulty Sensors: If the sensor is found to be defective, replace it to ensure accurate position readings.
  • Recalibrate System: After resolving any issues, perform a recalibration of the cab suspension system to ensure accurate sensor data and proper calibration.


Accurate sensor readings are critical for the calibration and operation of the cab suspension system. Regular checks and maintenance of sensors and their connections help ensure reliable performance.
