Start-Up Procedure and Diagnostic Menu

There are two ways to enter the diagnostic mode:

Start the vehicle, and at the disclaimer screen use the navigation display hard buttons:

Press and hold the DEST/ROUTE, the MAP/GUIDE, and the CANCEL buttons for about 3 seconds. The display screen goes directly to the Select Diagnosis Items menu shown.

Mode 2: 

Start the vehicle. When the globe screen appears, connect the SCS service connector  to the navigation service check connector located by passenger's Under-dash fuse/relay box. The screen changes to the System Link screen, and automatically begins running the self diagnosis. See the System Link information for more details.

NOTE: When finished troubleshooting, make sure to remove the SCS service connector.
