Navigation System Symptom Troubleshooting - Voice control does not work/respond

Voice control does not work/respond (KG and KE models)
Diagnostic Test: Mic Level
NOTE:

- Make sure that the correct 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 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.

- 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 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).

1. Measure the voltage between the HFT/navigation microphone 7P connector terminals No. 6 and No. 7 individually.

Is there battery voltage?

YES | - | Go to Step 3 .
NO | - | If the +B wire does not have voltage, repair open in the wire between the under-hood fuse/relay box and the HFT/navigation microphone 7P connector. If the ACC wire does not have voltage, repair open in the wire between the under-dash fuse/relay box and the HFT/navigation microphone 7P connector.■

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

1. Disconnect the HFT/navigation microphone 7P connector.

1. Check for continuity between HFT/navigation microphone 7P connector terminal No. 1 and body ground.

Is there continuity?

YES | - | Go to Step 6 .
NO | - | Repair an open in the wire between the HFT/navigation microphone and body ground (G501). ■

1. Reconnect the HFT/navigation microphone 7P connector.

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

1. Go into the Self-Diagnosis Mode select Mic Icon Menu, and use the Mic Level test under Functional Setup to check the operation of the Talk and Back buttons.

Are the navigation TALK and BACK buttons operational?

YES | - | Go to Step 9 .

Is the microphone operational?

YES | - | Check the operation of the voice control system (see the Navigation System Manual).■
NO | - | Go to Step 10 .

1. Disconnect the HFT control unit.

1. Disconnect the navigation unit connector C (16P).

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

Is there continuity voltage?

YES | - | Replace the affected shielded harness.
NO | - | Go to Step 13 .

1. 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 .

1. Check for continuity between navigation unit connector C terminal No. 8 and No 15 to No. 16, individually.

Is there continuity?

YES | - | Replace the affected shielded harness.■

NO

-

Substitute known-good components in this order until the problem goes away:■

- Microphone
- HFT unit
- Navigation Unit
