Voice control does not work/respond

NOTE:
  • Check the vehicle battery condition first (see BATTERY TEST ).
  • Make sure that the latest navigation software is installed.
  • Check any official Honda service website for more service information about the navigation system.
  • Before assuming that a voice complaint is hardware related, ensure that the voice control system is being operated correctly.
    • Make sure you are on the correct screen when trying to issue a voice command. For instance, the command "Find the nearest Italian Restaurant" only works on Map screen. (See the Navigation Manual for a complete list of allowed voice commands for the information being displayed)
    • Close the windows and moonroof
    • Set the fan speed to low (1 or 2)
    • Adjust the air flow from the air conditioning vents so that they do not blow against the microphone on the ceiling
    • Pause after pressing the TALK button then give a voice command clearly in a natural speaking voice. If the system cannot recognize your command, speak louder
    • If you speak a command with something in your mouth, or your voice is too husky, or high pitched, the system may misunderstand your command
  • Check the connectors for poor connections or loose terminals.
  • Check for a loose roof console microphone; if it's loose, tighten it.
  • Before troubleshooting, make sure you have the anti-theft code.
  • After troubleshooting, enter the anti-theft code.
  • Determine if the problem only happens to one person, or everyone who uses the system.
  • If the system only has a problem with one person's voice, this should be considered a system limitation.
  1. Turn ignition switch to ON (0).
  2. Check for the hard error code (see How to Check Error History (Navigation DTCs) ).

    Are there any DTCs indicated? 

    YES  -Troubleshoot the indicated navigation DTCs. ■

    NO  -Go to step 3.

  3. Do the HandsFreeLink™ system Self Diagnostic Function (see SELF-DIAGNOSTIC FUNCTION ).

    Do you hear "The hands free system is OK"? 

    YES  -Substitute a known good audio-navigation unit (including the HDD) (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ), and recheck. If the symptom/indication goes away, replace the original audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ). ■

    NO  -Check for HFL DTCs (see DTC TROUBLESHOOTING ). If the HFL does not respond, do the HFL control unit input tests (see CONTROL UNIT INPUT TEST ). ■
