SIC 523896.31 – S97 Control Lever (Potentiometer or Switch) for ESCV 2, Faulty

SIC 523896.31 (SIC )

Code: 523896.31



This error code, SIC 523896.31, is generated if the potentiometer signal voltage of the ESCV 2 (Electro-Hydraulic Section Control Valve) control lever is not to specification, or if the status of the switch on the control lever does not correspond to the signal voltage of the potentiometer.


When this error code is detected, the control unit may receive inconsistent signals from the potentiometer or switch, leading to potential control issues with ESCV 2.


  • Inspect Potentiometer and Switch:
    • Check the S97 control lever potentiometer and switch for any signs of damage, wear, or loose connections. Repair or replace as necessary.
  • Measure Signal Voltage:
    • Use a multimeter to measure the signal voltage from the potentiometer to ensure it is within the specified range.
  • Test Potentiometer and Switch:
    • Use diagnostic tools to test the potentiometer and switch for proper operation and accurate signal output.
  • Check Connections:
    • Ensure all connections are secure and free from corrosion or damage.
  • Update Software:
    • Ensure that the control unit firmware and software are up to date to rule out any software-related issues affecting the signal voltage and switch status.


Faulty signals from the potentiometer or switch can lead to incorrect control inputs. Regular inspection and maintenance of these components can help prevent such issues. If the problem persists, consult technical support for further diagnosis and repair.
