Vehicle Icon Wanders Across the Map When Driving (Does Not Follow A Displayed Road) or Map Vehicle ICON Spins
- Check the vehicle battery condition first.
- This is not the same condition as when driving off-road (or on a fire or logging road).
- This condition is caused by a loss of map matching from a bad sensor input. Check for aftermarket or other objects that can block the GPS signal. Always perform MAP MATCHING before proceeding with the troubleshooting.
- Verify that the correct audio-navigation unit is installed for this model. Go into the Diagnostic mode, and use VERSION .
- Make sure that the correct DVD color and version are installed.
- Check for aftermarket metallic window tinting.
- Inspect the DVD for dirt or damage (see HOW TO IDENTIFY NAVIGATION DVD VERSIONS, AND HOW TO INSPECT A DVD FOR DAMAGE ).
- Check any official Honda service website for more service information about the navigation system.
- Before troubleshooting, make sure you have anti-theft code for the navigation system.
- After troubleshooting, enter the anti-theft code for navigation system.
- Check the DVD for damage or scratches.
- Check the connectors for poor connections or loose terminals.
- Check the GPS icon on the navigation screen.
Is the GPS icon white or missing?
YES - Do the troubleshooting for GPS icon is white or not shown (see NAVIGATION DISPLAY BUTTONS DO NOT WORK OR RESPOND PROPERLY ).
NO - Go to step 2.
- Go into the Self-Diagnostic mode, and use the Yaw Rate diagnostic (see YAW RATE
) to check the yaw rate sensor.
Is the yaw rate sensor OK?
YES - Go to step 3.
NO - Replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).
- Go into the Diagnostic mode, and use the Car Status diagnostic (see YAW RATE TUNING
) to check the vehicle speed pulse (VSP) and the BACK signals.
Are the vehicle speed pulse and the BACK signals OK?
YES - The symptom may be a characteristic of the system. Check to see if the symptom occurs in the same place in a known-good vehicle. If it does, the problem could be in the database. Go to step 4.
NO -
- If the problem is the vehicle speed pulse, troubleshoot the vehicle speed signal circuit LT BLU wire for open or short. If OK, swap a known-good ECM/PCM. If the problem or symptom goes away, replace the original ECM/PCM (see ECM/PCM REPLACEMENT ).
- If the BACK signal is indicated ON (I) when in any shift lever position other than reverse, troubleshoot the back-up light switch circuit or MICU (A/T models).
- Substitute a known-good audio-navigation unit, and check to see if the problem occurs in the same place.
Does the problem occur in the same place?
YES - The problem is in the database, and should be considered a characteristic of the system. Report the problem according to the navigation system manual under Reporting Errors, and look for improvements in future databases.
NO - Replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).
