SIC 523898.03 – S99 Control Lever (Potentiometer) for ESCV 4, Voltage Too High

SIC 523898.03 (SIC )

Code: 523898.03

Shortcode:

Description:

This error code, SIC 523898.03, is saved when the potentiometer signal voltage of the ESCV 4 (Electro-Hydraulic Section Control Valve) control lever is outside the specified range, indicating a voltage that is too high.

Reaction:

When this error code is detected, the control unit may receive incorrect signals from the potentiometer, leading to potential control issues with ESCV 4.

Recommendations:

  • Inspect Potentiometer and Wiring:
    • Check the S99 control lever potentiometer and associated wiring for any signs of damage, wear, or loose connections. Repair or replace as necessary.
  • Measure Voltage:
    • Use a multimeter to measure the signal voltage from the potentiometer to ensure it is within the specified range.
  • Test Potentiometer:
    • Use diagnostic tools to test the potentiometer 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.

Note:

High voltage signals from the potentiometer can lead to incorrect control inputs. Regular inspection and maintenance of the potentiometer and associated wiring can help prevent such issues. If the problem persists, consult technical support for further diagnosis and repair.
