Voice Control Does Not Work

Voice control does not work

Diagnostic Test: Navi System Link and Functional Setup

NOTE:
- Always check the connectors for poor connections or loose terminals
- Before troubleshooting, write down the customer's radio station presets, and get the radio and navigation system anti-theft codes
- After troubleshooting, enter the radio and navigation system anti-theft codes, and the radio station 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 Owner's 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 of 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, the system may misunderstand your command.

1. Go into the Diagnostic mode and use the "Mic Level" diagnostic 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 navigation unit connector B (14P) terminal No.10 or a faulty voice control switch assembly.

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 Owner's Manual).

NO - Check for a loose front map light (microphone) assembly. If OK, check for an open or short to ground on navigation unit connector B (14P) terminals No.6 and No.14. If the wiring is OK replace the front map light assembly.
