Description:

This error code, SIC 523838.31, is saved when the potentiometer signal voltage of EICV 3 (Electro-Hydraulic Integrated Control Valve) is not within the specified range, or if the status of the switch on the multifunction lever does not correspond to the signal voltage of the potentiometer.

Reaction:

When this error code is detected, the control unit may receive incorrect signals from the potentiometer or switch, leading to potential control issues with the associated hydraulic functions.

Recommendations:

• Inspect Potentiometer and Switch:
  • Check the S64 MultiFunction 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 EICV 3 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 Wiring and Connections:
  • Inspect the wiring and connectors associated with the potentiometer and switch for any signs of damage or wear. Repair or replace as necessary.
• Update Software:
  • Ensure that the control unit firmware and software are up to date to rule out any software-related issues.

Note:

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.
