Description:

This error code, SCO 523775.31, indicates that the AIC control software detects an open circuit in the E-SCV activation switch. A transmitted replacement value generates this diagnostic trouble code in the SCO control software. In its active state, this fault can also generate a diagnostic trouble code at the AIC control software, which takes priority.

Reaction:

When this fault is detected, the control software may limit or disable the function of the selective control valves.

Recommendations:

• Inspect Wiring for Open Circuits:
  • Check the wiring and connections to the E-SCV activation switch for signs of open circuits. Repair or replace any damaged wires.
• Verify Activation Switch Function:
  • Ensure that the E-SCV activation switch is functioning correctly. Replace the switch if necessary.
• Test Electrical Connections:
  • Inspect all electrical connections for corrosion, looseness, or damage. Clean and secure connections as needed.
• Consult Technical Support:
  • If the issue persists, consult technical support for further diagnostics and assistance.

Note:

Preventive Maintenance:

• Regular inspections and maintenance of the activation switch and associated wiring can help identify and address potential issues before they cause operational problems.
