Navigation System 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.
- 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 moonroof.
- 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 the anti-theft code.
- After troubleshooting, enter the anti-theft code.
- 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 recheck.�
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 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.�
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 an open or high resistance in the wire between the HFL-navigation microphone and body ground (G401) Harness Locations.�
6. Go into the System Diagnostic Mode, and use the Mic Level test under Functional Setup Navigation System Diagnostic Mode 1 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 diagnosis under Functional Setup Navigation System Diagnostic Mode 1 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
