- This diagnostic tests the cables connecting the navigation components. Ensure that the ignition switch is in the ON (II) position. When the diagnostic begins you hear a bong sound. The system is in a Detecting mode, and is waiting for all items in white to be tested. This includes the navigation voice control (navigation TALK/BACK) buttons, and microphone. Press the navigation TALK button on the steering wheel, and in a normal voice, say "testing." The Talk indicator on the screen should turn green, and the voice level indicator should move to at least the 6th bar to pass. Next, press the navigation BACK button. The Cancel indicator should turn green.
- If all of the communication lines connecting the system components, and the navigation TALK/BACK buttons/microphone check out OK (all block diagram items green), then the OK indicator turns green.
- If there is a problem with the system, the faulty system component item turns to red, and the screen shows NG in red. Use the troubleshooting index, and other diagnostic screens to help locate the problem.
- The indication on the screen may not change until you cycle the ignition switch. After repairing the affected cable or system, repeat this diagnostic.

NOTE:

- Green boxes and a green OK indicate that the communications lines (cables) are intact. This diagnostic does not necessarily imply that the individual components are functioning properly. For instance, the GPS antenna wire may be crushed, but still show as green. A road test, or other diagnostic may be necessary to find the problem.

- Select Return to return to the Diagnosis Menu.

NOTE:

NOTE: Check the vehicle battery condition first Battery Test.

There are two ways to enter the diagnostic mode:

Mode 1:

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

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

- Self-Diagnosis Mode (runs the automatic diagnosis of the navigation system)
- Detail Information & Setting (allows you to manually diagnose the navigation system)





Mode 2:

Start the vehicle. When the globe screen appears, connect the SCS service connector Component Tests and General Diagnostics to the navigation service connector located behind the navigation unit in the trunk. The screen changes to the System Links screen and automatically begins running the self diagnostic. See the System Links section for more information.

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

1. Enter this screen by connecting the SCS service connector or by selecting Self Diagnosis Mode from the navigation screen main menu. The message at the bottom of the screen flashes indicating the diagnostic is running. Make sure you enter the audio anti-theft code.

NOTE:

- The system cannot complete a full diagnosis unless the engine is running.
- DTC 1501 and/or 2703 can be stored when the ignition switch is at ACCESSORY (I). With the ignition switch in ACCESSORY (I), the A/C unit is turned off and the navigation unit loses communication and stores DTCs. Therefore, there is a possibility that the system is normal even though DTC 2703 is stored. Check system links with the engine running, and if it appears normal, the system is OK at this time.

2. Rotate the interface dial to select the icon you want to diagnose. Push in the selector to see the details of that diagnostic function.

The System Links function runs automatically and displays a flashing message at the bottom of the screen reminding you to have the engine running for the test. The diagnostic tests the following:

- Most of the wires connecting the navigation components are shown in the block diagram.
- The results from the various components shown in the block diagram.
- The microphone is tested by listening to the bong sound produced by the navigation unit from the speakers when the diagnostic is started. This requires that the audio system be operating normally.

When the diagnostic finishes, the icons turn different colors based on their test status. The color definitions are shown below and can also be seen by selecting Help on the System Links screen.

The indication on the screen may not change until you exit and reenter the Self-Diagnosis mode. In some cases, you may have to restart the engine for the indication to change. After you repair the affected component or harness, repeat this diagnostic.

Each icon color is explained in the table below.





NOTE: By selecting the HELP icon, you can see a description for each color.

Factory Diagnostic Screen In Line Diag

NOTE: If the vehicle left the factory in the factory diagnostic mode, you will see this screen every time you turn on the ignition. You may also see this screen if you recently replaced the navigation unit.

When a navigation unit is powered up for the first time at the factory or after replacement with a new or remanufactured navigation unit, the factory diagnosis screen (In Line Diag) appears. Normally the factory does the steps necessary to verify proper operation and terminate the factory diagnostic.

Until the proper confirmation sequence is done, the screen appears every time the vehicle is started.
