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. Testing and Inspection

- Check the connectors for poor connections or loose terminals.

- Make sure that the correct navigation DVD color and version are installed.

- Check any official Honda service website for more service information about 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 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.

- Check for a loose navigation microphone; if it's loose, tighten it.

- Before troubleshooting, make sure you have anti-theft codes for the audio system and the navigation system.

- After troubleshooting, enter the anti-theft codes for the audio system and the navigation system.

- 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. Turn the ignition switch to ON (II).

2. Go into the Self-Diagnosis Mode, select Mic Icon Menu, and use the Mic Level test under Functional Setup Navigation System Diagnostic Mode (With Navigation) to check the operation of the 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 navigation unit connector C (16P) No. 12 terminal.


3. Use the Mic Level diagnosis 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).

NO - Go to step 4.


4. Clear the hard error code. How to Troubleshoot the Navigation System (With Navigation)

5. Turn the ignition switch to LOCK (0), and then back ON (II).

6. Check the Error History. How to Troubleshoot the Navigation System (With Navigation)

Is Hard Error 2707 indicated?
YES - Do the 2707 troubleshooting.

NO - Go to step 7.


7. Measure the voltage between body ground and HFL-navigation microphone 7P connector terminals No. 6 and No. 7 individually.

Is there battery voltage?
YES - Go to step 8.

NO - If the +B wire does not have voltage, repair an open in the wire between the under-hood fuse/relay box and the HFL-navigation microphone 7P connector. If the ACC wire does not have voltage, repair an open in the wire between the driver's under-dash fuse/relay box and the HFL-navigation microphone 7P connector.






8. Measure the voltage between HFL-navigation microphone 7P connector terminal No. 1 and body ground.

Is there less than 0.2 V?
YES - Go to step 9.

NO - Repair an open or high resistance in the wire between the HFL-navigation microphone and body ground (G501).






9. Turn the ignition switch to LOCK (0).

10. Disconnect the HandsFreeLink control unit 28P connector.

11. Disconnect navigation unit connector C (16P).

12. Check for continuity between body ground and navigation unit connector C (16P) terminal No. 8 and No. 16 individually.

Is there continuity?
YES - There is a short to body ground in the wire(s) between the navigation unit and the HFL-navigation microphone. Replace the affected shielded harness.

NO - Go to step 13.






13. Check for continuity between navigation unit connector C (16P) terminals No. 8 and No. 16.

Is there continuity?
YES - There is a short in the wire(s) between the navigation unit and the HFL-navigation microphone. Replace the affected shielded harness.

NO - Go to step 14.






14. Check for continuity between navigation unit connector C (16P) terminals No. 8 and No 15.

Is there continuity?
YES - There is a short to in the wire(s) between the navigation unit and the HFL-navigation microphone. Replace the affected shielded harness.

NO - Substitute known-good components in this order until the problem goes away:

- HFL-navigation microphone Service and Repair

- HandsFreeLink control unit Service and Repair
