Symptom Troubleshooting




Symptom Troubleshooting: Voice control does not work/respond

Voice control does not work/respond

Diagnostic Test: Mic Level

NOTE:

- Check the vehicle battery condition first.

- Check the connector 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 troubleshooting, make sure you have the anti-theft code for the navigation system.

- After troubleshooting, enter the anti-theft code for the navigation system.

- Before assuming that a voice complaint is hardware related, ensure that the voice control system is being operated correctly.

- Adjust the air flow from the air conditioning vents so that they do not blow against the microphone on the ceiling.

- Set the fan speed to low (1 or 2).

- 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 a Map screen. (See the Navigation System Manual for a complete list of allowed voice commands for the information being displayed.)

- Close the windows, moonroof, and doors.

- Keep background noise and conversations to a minimum.

- 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.

- Compare the system operation with a known-good vehicle. Have more than one person test the system operation. If the known-good vehicle performs the same, it is a characteristic of the system.

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 navigation 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 the navigation unit connector D (5P) terminal No. 4 .


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) and compare system operation with a known-good vehicle.

NO - Check for a loose front map light (microphone) assembly. If OK, check for an open, or short to ground on navigation unit connector D (5P) terminals No. 1, No. 2, and No. 5. If the wire is OK, substitute a known-good microphone assembly.
