CSC 003511.03 – Overvoltage Issue at CSC Sensors. John Deere System Advisory.

CSC 003511.03 (CSC 3511.03)

Code: 003511.03

Shortcode: 3511.03


Error code CSC 003511.03 is triggered when the voltage supply to the 5-V components at the Cab Suspension Control Unit (CSC) sensors exceeds the normal threshold, measuring above 5.25 V. This typically indicates a potential short circuit to a positive supply lead or an internal disruption within the CSC control software, which may adversely affect sensor operation and data integrity.


The CSC control software may limit its functionality or stop functioning to prevent damage or incorrect operation based on faulty sensor inputs.


  • Inspect Voltage Supply Lines: Check for any signs of short circuits or unexpected voltage paths to the positive supply leads.
  • Test Sensor Voltage Levels: Use a multimeter to measure the voltage levels at the 5-V components to ensure they align with specified parameters.
  • Review and Rectify CSC Control Software: Investigate the CSC control software for any internal issues that could be influencing voltage control and rectify them.
  • Replace Faulty Components: If specific components are found to be causing overvoltage, replace them promptly.
  • System Resets and Diagnostic Tests: After corrective measures, reset the system and conduct comprehensive diagnostics to confirm all sensors operate within normal voltage ranges.


Regular monitoring of voltage levels at critical sensor points is crucial to maintaining the operational integrity and safety of the machinery’s control systems.
