Temperature Difference Exceeded

What does 0007 hex mean?

This diagnostic code (found within FA00:03 Temperature error) indicates that the temperature difference between the internal measuring points (e.g., Temperature Primary MC and Temperature Secondary MC, FA80:01 and FA80:02) has exceeded its permissible threshold. A significant temperature differential can suggest localized heating or cooling issues within the terminal, potentially leading to component stress or operational instability.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Inspect the terminal internally for any debris or obstructions that might impede heat transfer or cause localized heating.
