Honda HR-V: Navigation System Symptom Troubleshooting - Voice Control Does Not Work/Respond

Honda HR-V (2015-2021) Service Manual / Accessories & Equipment / Audio Visual Systems - Testing & Troubleshooting / Symptom Troubleshooting / Navigation System Symptom Troubleshooting - Voice Control Does Not Work/Respond

NOTE:

  • Check the vehicle 12 volt battery condition first.
  • Make sure that the latest navigation software is installed.
  • 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 Manual for a complete list of allowed voice commands for the information being displayed)
    • Close the windows and moonroof
    • 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 you speak a command with something in your mouth, or your voice is too husky, or high pitched, the system may misunderstand your command
  • 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.
  • Check the connectors for poor connections or loose terminals.

1. HFL switch operation check:

  1. Turn the vehicle to the ON mode.
  2. Go into the System Diagnostic Mode, and use the Hard Key to check the HFL switch.

Do all the HFL switch buttons respond?

YES

Go to step 2.

NO

Go to step 5.

2. Microphone operation check:

  1. Go into the System Diagnostic Mode, and use the HFT/Mic to check the microphone.
  2. Press the TALK button, then say "testing" in front of the microphone to check the Mic level.

Is the microphone level OK?

YES

Go to step 3.

NO

Go to step 4.

3. Problem verification:

  1. Turn the vehicle to the OFF (LOCK) mode then the ON mode.
  2. Pressing the TALK button, then give a voice command "Audio" clearly in a natural speaking voice.

Does the audio system turn on by the voice command?

YES

Intermittent failure, the system is OK at this time.

NO

Replace the audio-navigation unit.

4. Audio panel check (substitution):

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Substitute a known-good audio panel, and recheck.

Does the symptom go away?

YES

Replace the original audio panel.

NO

Replace the audio-navigation unit.

5. Determine possible failure area (Audio remote switch circuit, others).

Go into the System Diagnostic Mode, and use the Hard Key to check the audio remote switch.

Does all the audio remote switch buttons respond?

YES

Go to step 6.

NO

Go to Audio remote switch does not work properly (audio unit buttons work) (With Navigation) or Audio remote switch does not work properly (audio unit buttons work) (Without Navigation, Color Audio Type (5-inch Screen) ) or Audio remote switch does not work properly (audio unit buttons work) (Without Navigation, Display Audio Type (7-inch Screen) ).

6. HFL switch check:

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Do the HFL Switch Test.

Is the HFL switch OK?

YES

Go to step 7.

NO

Replace the HFL switch.

7. Determine possible failure area (Audio-navigation unit, others):

  1. Reconnect the HFL switch 7P connector.
  2. Disconnect the following connectors.

NOTE: Eject the disc before disconnecting the audio-navigation unit to prevent damaging the CD player's load mechanism.

Audio-navigation unit connector A (24P)

Audio-navigation unit connector B (20P)

  1. Measure the resistance between test points 1 and 2 as specified in the table.

Audio Visual Systems - Testing & Troubleshooting

Is the resistance OK?

YES

Go to step 8.

NO

Go to step 9.

8. Audio-navigation unit check (HFT/NAVI REMOTE SW line):

  1. Disconnect the following connector.

HFL switch 7P connector

  1. Check for continuity between test points 1 and 2.
