Possible Causes

Blown display fuse, Failed HMI module, Loose ribbon cable or connector, No DC supply from controller

How to Fix / Troubleshooting

Safety first: Disconnect battery negative and de-energize AC sources before opening the control panel.

  • Check fuses: Locate and test low-voltage fuses feeding the display or HMI. Replace blown fuses with identical ratings.
  • Inspect connectors: Reseat ribbon cables and plug connectors between the controller PCB and display module.
  • Measure DC supply: With power restored (qualified persons only), verify that the display is receiving the correct DC voltage from the controller.
  • Replace HMI: If supply voltage is present but the display remains blank, replace the HMI/display module with a Honda-specified part.
