OIC 003511.03 – 5-Volt Supply Voltage No. 3, Voltage Too High

OIC 003511.03 (OIC 3511.03)

Code: 003511.03

Shortcode: 3511.03


This error code indicates that the voltage at the positive voltage supply lead for 5-volt components exceeds 5.25 volts. This high voltage suggests a short to a supply lead.


The control software may function in a limited capacity or not at all, affecting the operation of 5-volt components.


Inspect Power Supply:

  • Check the power supply for 5-volt components to ensure it is functioning correctly and not supplying excessive voltage.

Inspect Wiring and Connections:

  • Inspect all wiring and connections for the 5-volt components for signs of damage, loose connections, or corrosion. Repair or replace any faulty components.

Test Voltage Levels:

  • Use a multimeter to measure the voltage at the supply lead. Ensure it does not exceed 5.25 volts. If it does, investigate the power source for faults.

Replace Faulty Components:

  • If any component is found to be causing the high voltage, replace it with a properly functioning unit.

Update Control Software:

  • Ensure that the control software is updated to the latest version. Firmware updates might improve voltage regulation.

Consult Manufacturer Support:

  • If the issue persists, consult technical support or the manufacturer for further diagnostics and assistance.

Monitor System Performance:

  • After taking corrective actions, monitor the system to ensure the voltage remains within the specified range and the error does not recur.


Regular maintenance and checks of the power supply and 5-volt components can prevent voltage-related issues and ensure reliable operation.
