Voice control does not work/respond
Voice control does not work/respondDiagnostic Test: Mic Level
NOTE:
- Always make sure that the correct DVD color and version are installed.
- Check on-line for service bulletins or other service information for 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 sunroof.
- 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.
- Always check the connectors for poor connections or loose terminals.
- Check for a loose roof console microphone; if it's loose, tighten it.
- Before troubleshooting, write down the audio presets, and get the audio and navigation system anti-theft codes.
- After troubleshooting, enter the audio and navigation system anti-theft codes, and 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. Use the HDS to check for HFL DTCs. Troubleshoot and resolve any HFL problems before continuing.
Are there any HFL DTCs?
YES - Perform the troubleshooting for the DTC indicated.
NO - Go to step 2.
2. Go into the Diagnostic mode and use the "Mic Level" diagnostic the under Functional Setup to check the operation of the Talk and Back buttons.

Is there continuity?
YES - Go to step 6.
NO - Repair open in the wire, or replace the cable reel.
6. Check for continuity between cable reel 20P connector terminal No. 1 and navigation unit connector B (14P) terminal No.10.
Is there continuity?
YES - Go to step 7.
NO - Repair open in the wire in the harness, or replace the cable reel.
7. Check for continuity between body ground and cable reel 20P connector terminals No. 10 and No. 19.
Is there continuity?
YES - Repair short to body ground in the wire harness, or replace the cable reel.
NO - Replace the navigation unit.
8. 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).
NO - Go to step 9.
9. Turn the ignition switch OFF.
10. Disconnect HandsFreeLink control unit 28P connector and navigation unit connector B (14P).
11. Check for continuity between navigation unit connector B (14P) terminal No. 6 and No. 14, and the HandsFreeLink control unit 28P connector terminal No. 27 and No. 28.
Is there continuity?
YES - Go to step 12.
NO - Open in the wire(s) between the navigation unit and HandsFreeLink control unit. Replace the affected shielded harness.
12. Check for continuity between body ground and navigation unit connector B (14P) terminal No. 6 and No. 14 individually.
Is there continuity?
YES - Short to body ground in the wire(s) between the navigation unit and HandsFreeLink control unit. Replace the affected shielded harness.
NO - Go to step 13.
13. Check for continuity between the navigation unit connector B (14P) terminal No. 13 and body ground.
Is there continuity?
YES - Short in the wire between the navigation unit and HandsFreeLink control unit. Replace the affected shielded harness.
NO - Go to step 14.
14. Check for continuity between the HandsFreeLink control unit 28P connector terminal No. 13 and No. 14 to body ground.
Is there continuity?
YES - Short in the wire(s) between the HandsFreeLink control unit and roof console. Replace the affected shielded harness.
NO - Go to step 15.
15. Check for continuity between the HandsFreeLink control unit 28P connector terminal No. 12 and terminals No. 13 and No. 14.
Is there continuity?
YES - Short in the wire(s) between the HandsFreeLink control unit and the roof console. Replace the shielded harness.
NO - Go to step 16.
16. Disconnect the roof console 20P connector.
17. Check for continuity between the appropriate HandsFreeLink control unit 28P connector terminals and the roof console 20P connector terminals.
Is there continuity?
YES - Substitute a known-good roof console, then reconnect all of the connectors and recheck. If the symptom/indication goes away, replace the original roof console. If the symptom/indication is still present, replace the HandsFreeLink control unit.
NO - Open in the wire(s) between the HandsFreeLink control unit and the roof console. Replace the shielded harness.
