Diagnostic System Diagram

WARNING: This page is about a different car, the 2009 Acura MDX, 2008 Acura MDX, and 2007 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

This diagram represents the diagnostic slice in the Navigation Functional diagram. The diagram shows an overview of the navigation diagnostic features starting at the center and working outward in layers. The diagram starts with Key on. The diagram shows two ways to get to the diagnostic main menu:

By starting the vehicle with the SCS connector plugged in, you will enter the diagnostic System Links screen, select Return to get to the main diagnostic menu.
From any of the navigation Map or Menu screens, press and simultaneously hold the keys Menu + Map + Cancel.

The diagram shows the available diagnostic menu choices, starting at the bottom left, and moving clockwise. 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 asks you to insert a PCMCIA memory card into the PC Slot, insert the PC card and the menu options referring to the PC card become available.
