DTI 001491.11 – CommandCenter Background Lighting Fault

DTI 001491.11 (DTI 1491.11)

Code: 001491.11

Shortcode: 1491.11


This diagnostic trouble code (DTC) is generated when the DTI control unit is unable to activate the background lighting of the CommandCenter. This issue may result from electrical problems, such as faulty wiring, defective light components, or issues within the control unit itself that prevent power from reaching the backlight system.


The lack of background lighting can reduce the visibility of the display interface, potentially impacting the operator’s ability to monitor and control machine functions effectively, especially in low-light conditions.


  • Check Electrical Connections: Inspect the connections and wiring associated with the background lighting system for loose connections or damage.
  • Replace Faulty Components: Identify and replace any faulty components such as LEDs or other lighting elements.
  • Test Control Unit Outputs: Verify that the control unit is providing the correct outputs to power the lighting system. Consider technical support if the issue is related to the control unit’s functionality.


Ensuring the functionality of the CommandCenter’s background lighting is crucial for optimal visibility and operation. Regular checks and prompt repair of lighting components can enhance the usability and functionality of the equipment.
