Reset the Acuralink Control Unit
*RESET THE ACURALINK CONTROL UNITAcuraLink is a two-way communication system between the vehicle and American Honda, using the XM satellites. It works with the vehicle's navigation system, Hands FreeLink system, and audio system.
When the No.15 fuse is removed during vehicle shipment, the AcuraLink control unit sets DTCs. These DTCs need to be cleared during the TQI using this procedure:
1. Start the engine.
2. On the navigation system disclaimer screen, select OK by pressing the interface dial. (The interface dial is the large knob at the center of the dashboard. It has two parts: an outer knob and an inner selector. The interface dial is used to control several functions, including AcuraLink.)
3. Next to the interface dial, press and hold the MAP- GUIDE, MENU, and CANCEL buttons at the same time, until the Select Diagnosis Items screen is displayed.
4. Turn the interface dial to highlight the Self- Diagnosis Mode icon on the screen, then press the interface dial to select Self-Diagnosis Mode. Allow the diagnostic to run.
5. Turn the interface dial to highlight the XM (HIP) icon on the screen, then press the interface dial to select XM (HIP).
6. Turn the interface dial to highlight the XM (HIP) Diag icon, then press the interface dial to select XM (HIP) Diag.
NOTE:
If the select diagnosis item menu screen does not appear, do this:
^ To establish communication with the navigation system, disconnect the negative cable from the battery for 30 seconds, reconnect it, then repeat steps 1 thru 6.
^ Because you have disconnected the battery, do this:
- Reenter the audio unit anti-theft code and the radio station presets.
- Reenter the navigation system code.
- Redo the idle learn procedure.
7. Turn the interface dial to highlight the Data Reset icon. Then press the interface dial to select Data Reset.
8. Turn the interface dial to highlight the Yes icon. Then press the interface dial to select Yes.
9. Select OK by pressing the interface dial, then toggle the interface dial to the left one time.
10. Press the CANCEL button.
11. Turn the interface dial to highlight the Return icon. Then press the interface dial to select Return.
12. Again, turn the interface dial to highlight the Return icon. Then press the interface dial to select Return. This returns you to the navigation system screen.*
System Limitations
These issues could arise during the TQI or after installing replacement parts to repair the system. Refer to the navigation system manual or the quick start guide (2009) or the advanced technology guide (2010) for basic operation.
To minimize distractions, always use the voice control system to operate the navigation system while driving. Always verify the audio and visual route information by carefully observing roadway signs, signals, etc. Use your own good judgment, and obey traffic laws while driving.
The navigation system has these limitations:
The GPS (global positioning system) satellites used by the navigation system are operated by the U.S. Department of Defense. For security reasons, certain inaccuracies are built into the GPS. This can cause occasional positioning errors of up to several hundred feet. If the navigation system indicates your position incorrectly, wait several seconds until it corrects itself. The system may also correct itself after you make a turn or cross a road.
^ The routes calculated by the system may not always be what you consider to be the most direct ones. Try different routing methods to obtain the best route. Even the direction your vehicle is pointing influences the route calculation.
^ Since businesses fail or move to new locations, some information may be inaccurate. Also, route guidance may conflict with actual road conditions, such as street closures, construction, and detours.
^ Occasionally, the navigation system may reboot due to excess cold, heat, or shock, or from recalculating a route too many times. Rebooting does not necessarily indicate a need for service.
^ The GPS antenna receives location information from orbiting satellites. Anything that blocks or interferes with the signal affects accuracy. The GPS signal can be blocked or interfered with (vehicle position shown incorrectly on the map) by:
- Aftermarket metallic window tinting above or to the sides of the GPS antenna.
- Aftermarket vehicle theft location systems mounted near the navigation control unit or display.
- Radar detectors, cell phones, or other aftermarket electronic accessories placed near the navigation control unit or display.
- Outside electrical interference from overhead power or trolley lines or broadcast sources.
- Tall trees or buildings near or over the vehicle. They can cause the system to show the vehicle on an adjacent street. This should automatically correct itself when the obstruction is gone.
^ In some cases, a city name, road name, or address range may be incorrect or missing from the system. The possible causes are:
- The city name may be listed under a larger metropolitan area, or as an unincorporated area. Try selecting the street name first. If it is a smaller city in a rural area, only the main road may be shown.
- If the street name cannot be found, is shown incorrectly on the map, or is not drawn correctly, it may be because it is a new road, or it is in an unverified area.
NOTE:
See the navigation system manual for more information.
^ If the location of your dealership is shown incorrectly or needs to be changed, report it to your DPSM.
^ If the DVD door in the control unit is opened or the DVD is removed, the system will display an error message, "Navigation unit door is open or No DVD Disc is installed. Please check system."
^ Scratches or fingerprints on the surface of the DVD can cause system errors. Always handle the DVD by its edges. A DVD with a white label (Canadian vehicles may have a gray label) is used for this system. It cannot be interchanged with a DVD from a different vehicle that has a different-colored label.
