Navigation System Symptom Troubleshooting - Voice control does not work/respond
Voice control does not work/respond (KG and KE models)
Diagnostic Test: Mic Level
NOTE:
  • Make sure that the correct version are 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 System manual for a complete list of allowed voice commands for the information being displayed).
    -
    Close the windows and sunroof.
    -
    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 the microphone picks up voices other than yours, the system may not interpret your voice commands correctly.
    -
    If you speak a command with something in your mouth, or your voice is too husky, 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 anti-theft codes for the audio system and the navigation system.
  • After troubleshooting, enter the anti-theft codes for the audio system and the navigation system.
  • 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 the ignition switch to ON (II).
  1. Measure the voltage between the HFT/navigation microphone 7P connector terminals No. 6 and No. 7 individually.
Is there battery voltage?
YES -
Go to Step 3 .
NO -
If the +B wire does not have voltage, repair open in the wire between the under-hood fuse/relay box and the HFT/navigation microphone 7P connector. If the ACC wire does not have voltage, repair open in the wire between the under-dash fuse/relay box and the HFT/navigation microphone 7P connector.■
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the HFT/navigation microphone 7P connector.
  1. Check for continuity between HFT/navigation microphone 7P connector terminal No. 1 and body ground.
Is there continuity?
YES -
Go to Step 6 .
NO -
  1. Reconnect the HFT/navigation microphone 7P connector.
  1. Turn the ignition switch to ON (II).
Are the navigation TALK and BACK buttons operational?
YES -
Go to Step 9 .

Is the microphone operational?
YES -
Check the operation of the voice control system (see the Navigation System Manual).■
NO -
Go to Step 10 .
  1. Disconnect the HFT control unit.
  1. Disconnect the navigation unit connector C (16P).
  1. Check for continuity between navigation unit connector C (16P) terminal No. 8 and No. 16 and body ground.
Is there continuity voltage?
YES -
Replace the affected shielded harness.
NO -
Go to Step 13 .
  1. Check for continuity between navigation unit connector C (16P) terminals No. 8 and No. 16.
Is there continuity?
YES -
Replace the affected shielded harness.
NO -
Go to Step 14 .
  1. Check for continuity between navigation unit connector C terminal No. 8 and No 15 to No. 16, individually.
Is there continuity?
YES -
Replace the affected shielded harness.■
NO -
Substitute known-good components in this order until the problem goes away:■
  • Microphone
  • HFT unit
  • Navigation Unit
