Navigation System Diagnostic Mode

Start-up procedure and Diagnostic Menu

There are two ways to enter the diagnostic mode:

Start the vehicle and at the globe screen connect the SCS service connector to the navigation service connector located behind the navigation unit in the glove box. The screen changes to the System Links screen 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.

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

Make sure the battery is in good condition then press and hold the three buttons (MAP, MENU, and CANCEL), and keep them pressed for about 3 seconds. The display screen will go 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)

System Links

Enter this screen by connecting the SCS 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.

NOTE: the system cannot complete a full diagnosis unless the engine is running.

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:

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 re-enter 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.

Explanation of each icon

Each color of the icon are explained in the table below.

Icon Colors	Description
Green	The system ran a diagnosis and the results are OK.
Red	Errors that require replacement of hardware or harness. Examples are connection error or memory diagnosis error.
Yellow	Errors that doesn't require hardware replacement, such as an open display cover, an inserted different model's disc, leaving the vehicle in ACC (I), or because of a missing accessory.

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.

When a navigation control 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) shows up. 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 will show up every time the vehicle is started.

Follow the steps below to prevent the screen from showing up in the future:

Press and hold the buttons (MENU + MAP + CANCEL) for about 3 seconds (the Select Diagnosis items screen appears).
Press and hold the MAP button for 5−10 seconds (a screen with a Complete button, appears).
Complete, then Return, and then shut the key off for 5 seconds. Do not disconnect the battery during this period as the unit is saving the setting to the SRAM memory. The In Line Diag should not appear again.
Restart the vehicle, and confirm normal operation by completing the TQI of the Navigation System Service Bulletin.

Monitor Check

Overview of display unit

The display unit communicates with the navigation unit over its own GA-Net bus. Information sent by the navigation unit to the display unit includes commands to control the LCD back light.
The security system protects the navigation display unit by daisy-chaining the security signal through it, and then passing the signal to the audio unit.
The illumination input from the gauge brightness control provides back lighting for the buttons surrounding the screen.

These screens allow you to troubleshoot the display unit. Select the item you want to troubleshoot, and follow the diagnostic instructions.

Detailed Information & Setting

These section allows you to run a specific diagnostic and allows additional setting choices for some screens that are not shown when selecting an icon from the System Links screen.

When the menu item Detail Information & Setting is selected, the main diagnosis menu is displayed.

RGB Color

This screen verifies that the display unit is receiving the video (R, G, B and Composite sync) signals properly. The three primary colors should all be shown without distortion. The combination of all three should produce a central white section. If any of the colors are missing, troubleshoot for the color signal. If the picture has lines in it or rolls horizontally, or vertically, troubleshoot for a Composite sync problem.

Gray Tone

This screen diagnoses problems with contrast. You should be able to see the changes from bar to bar across the scale. It is normal for the two bars on either side to appear the same. If you can't see changes from bar to bar, replace the navigation unit.

Black Raster

This diagnostic screen checks for pixels that may be stuck on. The entire display must be black. Is pixels are stuck on, replace the navigation unit.

Color Pattern

The chart below shows the colors being used for the map and menu screens. This is for factory use only. To check the color signal use the RGB Color diagnostic found under the Monitor Check.

White Raster

This diagnostic screen checks for pixels that may be dead (off). The entire display must be white. If there are dead pixels, replace the navigation unit.

Monitor Adjustment

This allows you to center the navigation display. Use the joystick to move the picture up/down or left/right. It is unlikely that you will ever need to adjust the monitor position. The Default button will reset the display position to factory specifications.

Unit Check (Quick Check)

Some of the tests and screens that are displayed under the Unit Check are different from the more detailed checks listed in other areas of this service manual.

To start the test, select the item you want to check.

Display

This diagnostic does additional checks on the communication bus between the control unit and the display. In addition, the internal electronics functionality are confirmed.

When the connection is NG, first check for loose terminals at the navigation unit and the display unit connections. Next check for an open or short in the communication line between the navigation unit and the display unit. If you find the line has an open or short, replace the affected shielded harness.
If the ROM or RAM is NG, replace the display unit.
The version represents the software version in the display.

Radio

If NG is indicated, check for loose audio unit connectors.

GPS

If GPS indicates NG (ANT), then check the entire GPS antenna wire from the navigation unit to the antenna. If the wire is crushed or damaged, try a known good antenna. If this diagnostic reads OK, then order a new GPS antenna. If the diagnostic still reads NG (ANT), then replace the navigation unit.

Functional Setup

Select the item you want to check.

Mic Level

Mic Level

This diagnostic allows you to independently test the microphone and the navigation TALK and BACK buttons. They are used to activate the voice control system. The microphone is located near the map light in the roof console. It is directional, and works only with the voice coming from the drivers seat.

Press the TALK button on the steering wheel, and in a normal voice say testing. The TALK indicator on the screen should momentarily turn green, and the text Now Recording... should appear in yellow. In addition, the Mic Level indicator shown on the screen does not briefly turn green, then check the wiring from the steering wheel talk button to the navigation unit. If there is no Mic Level movement when you speak, then you should check the wires running from the microphone in the roof console to the Hands Free Telephone control unit and the navigation unit. If the wires are OK, the microphone must be faulty; replace the microphone located in roof console.
Press the BACK button on the steering wheel. This should cause the Cancel indicator on the screen to momentarily turn green. If it does not briefly turn green, check the wiring from the steering wheel BACK button to the navigation unit.

GPS Information

This screen shows the current status of GPS reception. The circular diagram shows the current location of the GPS satellites (yellow numbers) as they would appear in the sky. The outer circle represents the horizon (0 degrees elevation). The middle and inner circles represents 30 and 60 degrees respectively. The very center of the diagram (90 degrees elevation) is directly overhead. Nearby obstructions, like tall buildings will block satellites in that direction. That is why it is necessary to be in an open area to effectively troubleshoot GPS reception issues. The satellite numbers shown on the diagram correspond to the PRN number in the GPS Details screen. There are always at least 24 active GPS satellites in orbit. Because satellites fail, and have to be removed from service, spares are always parked in orbit, ready to be activated. This is why the PRN (satellite ID number) can be greater than 24.

NOTE: To use this screen for troubleshooting, the vehicle should be outside away from buildings, tall trees, and high-tension wires for at least 10 minutes with the engine running.

The Number of Satellites box shows the number of acquired satellites (maximum of 12). It should contain three or more icons. If not troubleshoot for GPS icon is white or not shown.
The Current Position shows latitude, longitude, and elevation (in feet). If there are less than four satellites, the elevation can be grossly inaccurate.
The Date/Time field shows the current date, and also a time that includes daylight savings and other offsets entered by the customer in Setup screen 2 Adjust Time Zone/Clock.

NOTE: Pressing the map guide button displays the satellite number on each circle.

GPS Detail

By pressing and holding the MENU button for 2 seconds, a GPS Detail screen appears. This screen displays real time incoming satellite positional data when the vehicle is outside in the open. The information shown on this screen is for factory use.

The box TS/AS and H Dop/V Dop is for factory use.
The Speed and Direction information is updated in real time when driving.
The Date/Time Information is the same as in Setup screen 2 Adjust Time Zone/Clock.
If the 3D icon is shown above the yellow dots, this implies that at least four satellites are available for map positioning, and the GPS indicator on the map screen will be green. See the Global Positioning System detailed explanation in the System Description.
If the row of data in the table below begins with a yellow dot, the AZI and EL fields can be used to locate each satellite on the circular GPS diagram (see prior screen).

NOTE: The data shown in the GPS Detail screen is an example only.

The table of values shown on the screen has the following columns:

Column	Description	Problem indication
3D	Active satellites (Yellow Dot)	If 3D or 2D is missing when the vehicle is parked outside, follow GPS icon is white or not shown troubleshooting.
PRN	The satellite ID number
ST	The status: 0 = cannot view or searching, 2 = acquiring	If all 0, then, follow GPS icon is white or not shown troubleshooting.
AZI	Azimuth, the angle (0−360) clockwise from north
EL	Elevation from the horizon (90 deg. is overhead)
C/N	N/A	Normal signal is 49-52, no signal: 27-33
ACC	N/A
△ 1/2 or 2/2 ▽	Shows view of all satellites in two screen views 1/2 or 2/2

Yaw Rate

This diagnostic checks the yaw rate sensor in the control unit. This device detects when the vehicle turns, and repositions the vehicle position icon on the map screen. For more detailed information, see the yaw rate sensor theory of operation under System Description.

Sensor indicates the voltage output from the yaw rate sensor. It should indicate about 2.500 V when stopped.
Offset is the reference voltage or standard within the yaw rate sensor. It also should indicate about 2.500 V when stopped.
A sensor output voltage LOWER than the Offset voltage indicates that the vehicle is turning to the right.

A sensor output voltage HIGHER than the Offset voltage indicates that the vehicle is turning to the left.
The yaw rate offset, and sensor should both indicate about 2.500 V when stopped. If either reads zero, or 5.000 V, replace the navigation unit.
The yaw rate offset and sensor should be within +/−0.01 V of each other when stopped. The sensor value should change relative to the offset as the car is turned while driving. If not, replace the navigation unit.

Example: Vehicle stopped

Normal		Abnormal
Offset	2.526 V	Offset	2.526 V
Sensor	2.516−2.536 V	Sensor	2.623 V

Example: Vehicle turning

Normal		Abnormal
Offset	2.526 V	Offset	2.526 V
Sensor	2.678 V (left turn) 2.478 V (right turn)	Sensor	2.623 V(no change on turns)

Sensitivity study represents the status of the internal tuning function. At initialization, this value starts at 6 and increases to 10 as the internal correction values become more accurate.
The settings CCW Cal Factor, CW Cal Factor, and Set are for factory use only. THIS SHOULD NEVER BE ADJUSTED.
For detailed analysis of the yaw rate select tuning.

Yaw Rate Tuning

This diagnostic allows you to graphically display problems with the yaw rate sensor.

The ANG-Disp value accumulates any differences between the offset, and sensor voltages (see Yaw Rate diagnostic). When the sensor is functioning properly, the random changes in these two voltages generally cancels out, so the value is 0. However if one voltage is consistently higher than the other, then the ANG-Disp value accumulates the constant change.
The Reset button temporarily clears the angular accumulation (ANG-Disp), and clears the display dots.
Do not touch the CCW, CW, or Set buttons. These are used for factory setup only.

Two tests are explained below. For large problems with the sensor values, the stationary test usually confirms whether the sensor is defective. For yaw rate issues related to driving, do the road test described below.

Stationary test: If the VP icon spins in place and the ANG-Disp value slowly increases or decreases in value, the yaw rate sensor is defective. Replace the navigation control unit.

Road test: Drive the vehicle on a very straight road. Enter the diagnostic mode, select Yaw rate, and touch the Tuning button. While driving down a straight road, the white dots should trace a straight line across the screen. However, if you are driving on a straight road, and you notice the dots constantly dropping down or heading up as you drive, the navigation control unit's yaw sensor is defective. You can touch Reset to clear ANG-Disp, and dotted lines.

If either test above fails, please enter Yaw rate sensor defective for the problem description, on the Navigation core return form.

NOTE: The CCW, CW and Set buttons are disabled and cannot be activated.

Car Status

Use this screen to confirm that the navigation unit is properly receiving input signals. Signals equal to (0) are OFF, and signals equal to (1) are ON. If the value on the display does not match the actual vehicle status, then check the wire carrying the signal.

VSP-Vehicle Speed Pulse from ECM (Pin 6 of A-connector)

a) OFF (0) when vehicle is not moving

b) ON (1) when vehicle is moving

The VSP comes from the ECM as a dedicated signal. Internally, the navigation unit compares the actual VP on the map against street data to adjust the pulse to speed scaling factor. As this scaling factor becomes more accurate, the Level gradually increases from 0 to 10 (see the Tire Calibrate diagnostic screen).

BACK-Reverse indication from taillight relay (Pin 5 of A-connector)

a) OFF (0) when the shift lever is in any position other than reverse

b) ON (1) when the shift lever is in reverse

The Back signal is used by the navigation unit to allow the map screen to show the VP moving backwards when in reverse. This signal is needed because the Speed Pulse has no direction indication.

ILL CANCEL

This item detects whether the illumination cancel function is in use.

a) OFF (0) if illumination cancel is not selected

b) ON (1) if illumination cancel is activated

The illumination cancel function is activated by increasing the dash brightness to MAX. The F-CAN bus passes this information from the gauge assembly to the navigation control unit.

NOTE: This setting is unaffected by the display mode hard button located below and to the left of the interface dial.

Version

This screen displays the current version information for the navigation system software. In addition, this screen allows the loading of updated software if requested by the factory, or instructed by a Service Bulletin. Software may be loaded from a CD.

Program Flash: Displays the version of the navi software in memory.
Program Disc: If displayed, this value represents the version of the navi software on the navi DVD.
IPL, APL, DBOOT, and System uCom, are all for factory use.
Model: For this model, the field should begin with SMR.
Download: Do not touch, unless instructed by the factory.

Check any official Honda service website for more service information about navigation DVDs.

There are two navigation DVDs produced for this model.
