Voice recognition does not work
- Always check the connector for poor connection or loose terminals.
- Before troubleshooting, make sure you have the navigation system 4-digit anti-theft code, then write down the audio presets.
- After troubleshooting, enter the anti-theft codes then enter the audio presets.
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 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.
- 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.
- 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, if is a characteristic of the system.
- Go into the Diagnostic Menu and use the "Mic Level" test under Functional Setup (see FUNCTIONAL SETUP
) to check the operation of the TALK and BACK buttons.
Are the TALK and BACK buttons operational?
YES -Go to step 2.
NO -Check for an open, or short to ground on the navigation unit connector D (5P) terminal No. 4.
- Use the "Mic Level" diagnostic under Functional Setup (see FUNCTIONAL SETUP
) 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 -Go to step 3.
- Check the voice control switch (see VOICE CONTROL SWITCH TEST
).
Is voice control switch OK?
YES -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.
NO -Replace the voice control switch (see Voice Control Switch Replacement ).
