CSC 523949.03 – High Voltage in Solenoid Valve for Raising Cab Suspension. John Deere System Advisory.

CSC 523949.03 (CSC )

Code: 523949.03



The error code CSC 523949.03 is detected when the solenoid valve supply voltage for raising the cab suspension is too high, typically indicating a short to a 12-volt source. This condition can impair the functionality of the solenoid valve and the cab suspension system.


The control software may restrict or disable the cab suspension functionality to prevent potential damage from the high voltage condition.


  • Inspect Electrical Connections: Check the wiring and connections for any signs of a short to the 12-volt source. Look for damaged or exposed wires and repair them.
  • Measure Voltage Levels: Use a voltmeter to measure the voltage at the solenoid valve to ensure it is within the acceptable range.
  • Replace Faulty Components: If the solenoid valve or associated wiring is damaged, replace the faulty components to restore proper functionality.
  • Verify System Configuration: Ensure the control software and system settings are correctly configured to manage the solenoid valve’s voltage requirements.
  • Conduct System Tests: After making repairs, reset the system and perform comprehensive tests to confirm that the solenoid valve operates correctly under normal voltage conditions.


Regular inspection and maintenance of electrical circuits are crucial to prevent overvoltage issues that can lead to equipment malfunction and ensure the reliable operation of the cab suspension system.
