Symptom Troubleshooting: Voice control does not work/respond

Voice control does not work/respond

Diagnostic Test: Mic Level

NOTE:

- Check the connectors for poor connections or loose terminals.

- Make sure that the correct DVD color and 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 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. Pay particular attention to the passenger's side air vent adjustment. The microphone will pick up noise if the passenger's side vent is pointed directly at it, potentially rendering the Navi and HFL Voice Recognition inoperative.

- Pause after pressing the navigation 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 vehicle battery condition first.

- Check for a loose roof console microphone; if it's loose, tighten it.

- Before troubleshooting, make sure you have the audio and navigation system anti-theft codes, then write down the audio presets.

- After troubleshooting, enter the audio and navigation system anti-theft codes, then enter the audio presets.

- 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).

2. Go into the Diagnostic Menu, and use the Mic Level test under Functional Setup Navigation System Diagnostic Mode (With Navigation) to check the operation of the TALK and BACK buttons.

Are the navigation TALK and BACK buttons operational?
YES - Go to step 3.

NO - Check for an open or short to ground on navigation unit connector B (14P) terminal No. 10.


3. Use the Mic Level diagnostic under Functional Setup Navigation System Diagnostic Mode (With Navigation) to check the operation of the microphone.

Is the microphone operational?
YES - Check the operation of the voice control system (see the Navigation System Manual).

NO - Check for a loose front map light (microphone) assembly. If OK, check for an open or short to ground at navigation unit connector B (14P) terminals No. 6 and No. 14 or a short to ground between navigation unit connector B (14P) terminal No. 6 and the HandsFreeLink control unit 28P connector terminal No. 21, and between navigation unit connector B (14P) terminal No. 14 and the HandsFreeLink control unit 28P connector terminal No. 22.
