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.

- Make sure that the latest navigation software is installed.

- Check any official Honda service web site 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 the connectors for poor connections or loose terminals.

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

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

- After troubleshooting, enter the anti-theft codes for 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. Connect the HDS to the DLC.

2. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

3. Check for DTCs with the HDS.

Are there any DTCs present?
YES - Troubleshoot the DTC, then retest.

NO - Go to step 4.


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

Is there battery voltage?
YES - Go to step 5.

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






5. 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 6.

NO - Repair open or high resistance in the wire between the HFL-navigation microphone and body ground (G401). Dashboard Wire Harness (View Of Driver's Side) Connector And Harness Locations






6. 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 TALK and BACK buttons operational?
YES - Go to step 7.

NO - Troubleshoot the HFL system.


7. Use the Mic Level diagnostic 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 8.


8. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

9. Remove the center console panel. Center Console Panel Removal/Installation

10. Disconnect the HandsFreeLink control unit 28P connector. Service and Repair

11. Disconnect the audio-navigation unit connector H (28P).

12. Check for continuity between body ground and audio-navigation unit connector H (28P) terminal No. 27 and No. 28 individually.

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

NO - Go to step 13.






13. Check for continuity between audio-navigation unit connector H (28P) terminals No. 27 and No. 28.

Is there continuity?
YES - There is a short in the wires between the HandsFreeLink control unit and the audio-navigation unit. Replace the affected shielded harness.

NO - Go to step 14.






14. Check for continuity between the terminals of audio-navigation unit connector H (28P) according to the table.





Is there continuity between any of the terminals?
YES - There is a short in the wires between the HandsFreeLink control unit and the audio-navigation unit. Replace the affected shielded harness.

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

- HFL-navigation microphone

- HandsFreeLink control unit

- Audio-navigation unit
