Voice Recognition Does Not Work

Voice recognition does not work

NOTE:
- 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 customer's audio presets.
- After troubleshooting, enter the navigation system anti-theft code, 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 like known-good vehicle. Have more than one person test the system operation. If the like known-good vehicle performs the same, it is a characteristic of the system.

1. Go into the Diagnostic Menu and use the "Mic Level" test under 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.

2. Use the "Mic Level" diagnostic under 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.

3. Check the voice control switch.

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 wires are OK, substitute a known-good microphone assembly.

NO - Replace the voice control switch.
