Symptom Troubleshooting
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 Battery Test.
- 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 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 for the audio system and the navigation system.
- After troubleshooting, enter the anti-theft code 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 LOCK (0).
2. Connect the HDS to the DLC.
3. Turn the ignition switch to ON (II).
4. Check for DTCs with the HDS.
Are there any DTCs present?
YES -
Troubleshoot the DTC, then recheck.
NO -
Go to step 5.
5. Measure the voltage between body ground and roof console 28P connector terminals No. 4 and No. 28 individually.
Is there battery voltage?
YES -
Go to step 6.
NO -
If the +B wire does not have voltage, repair open in the wire between the driver's under-dash fuse/relay box and the roof console 28P 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 roof console 28P connector.
6. Measure the voltage between roof console 28P connector terminal No. 13 and body ground.
Is there less than 0.2 V?
YES -
Go to step 7.
NO -
Repair an open or high resistance in the wire between the roof console and body ground (G601).
7. Go into the Self-Diagnosis Mode select Mic Icon Menu, and use the Mic Level test under Functional Set-up to check the operation of the TALK and BACK buttons.
Are the navigation TALK and navigation BACK buttons operational?
YES -
Go to step 8.
NO -
Check for an open or a short to ground on navigation unit connector C (16P) terminal No. 12.
8. Use the Mic Level diagnostic under Functional Set-up 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 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) terminals No. 8 and No. 16 individually.
Is there continuity?
YES -
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 -
Replace the affected shielded harness.
NO -
Go to step 14.
14. Check for continuity between navigation unit connector C terminals No. 8 and No 15, and between terminals No. 8 and No. 16.
Is there continuity?
YES -
Replace the affected shielded harness.
NO -
Substitute known-good components in this order until the problem goes away:
- Microphone Service and Repair.
- HandsFreeLink control unit Service and Repair.
- Navigation Unit Service and Repair.
