Diagnostic Function Diagram

This diagram shows the diagnostic slice of the System Function Diagram. It has the diagnostic features of the navigation system starting at the center and working outward in layers. The diagnostic starts at "Key ON", and then displays the Diagnostic Main Menu (Select Diagnosis items) after:
Starting the vehicle with the SCS connector plugged in to the navigation service check connector to get to the System Links screen, then selecting Return.
Simultaneously pressing and holding the MENU, MAP/GUIDE, and CANCEL buttons. The diagram shows the available menu choices starting at the button left and moving clockwise. You will find a detailed explanation of each feature on the given page numbers. In most cases, do not clear or change settings in any diagnostic screen unless instructed to do so in the explanation or by the factory. If the factory supplies you with a PCMCIA card to place in the PC Card slot, then the features specified in the diagram with "Card" are available. The section labeled "For Developer Only" contains items for factory use. For instance, the factory might ask you for information from System History.
