Navigation System - Voice control does not work/respond
- 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.
- HFL switch input check
-1. Turn the vehicle to the ON mode.
Does all the HFL switch buttons respond?
YES
Go to step 2.
NO
Go to Audio remote-HFL switch does not work properly (audio unit buttons work) troubleshooting .
- Microphone input check
-1. Go into the System Diagnostic Mode, and use the 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.
- 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
- Determine possible failure area (microphone signal circuit, others)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connector.
Front HFL-ANC microphone 8P connector -3. Turn the vehicle to the ON mode.
-4. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode Front HFL-ANC microphone 8P connector: disconnected Test point 1 Front HFL-ANC microphone 8P connector No. 1 Test point 2 Front HFL-ANC microphone 8P connector No. 2 Is there about 8.0 V?
YES
Go to step 5.
NO
Go to step 8.
- Determine possible failure area (MIC PWR line, others)
-1. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode Front HFL-ANC microphone 8P connector: disconnected Test point 1 Front HFL-ANC microphone 8P connector No. 4 Test point 2 Body ground Is there about 8.0 V?
YES
Replace the front HFL-ANC microphone .
NO
Go to step 6.
- Open wire check (MIC PWR line)
-1. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode Front HFL-ANC microphone 8P connector: disconnected Test point 1 Telematics control unit connector A (32P) No. 10 Test point 2 Body ground Is there about 8.0 V?
YES
Repair an open in the wire.
NO
The MIC PWR wire is not open. Go to step 7.
- Shorted wire check (MIC PWR line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connector.
Telematics control unit connector A (32P) -3. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Front HFL-ANC microphone 8P connector: disconnected Telematics control unit connector A (32P): disconnected Test point 1 Telematics control unit connector A (32P) No. 10 Test point 2 Body ground Is there continuity?
YES
Repair a short to body ground in the wire.
NO
- Determine possible failure area (ECALL-NAVI MIC- line, others)
-1. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode Front HFL-ANC microphone 8P connector: disconnected Test point 1 Front HFL-ANC microphone 8P connector No. 1 Test point 2 Body ground Is there about 8.0 V?
YES
There is a short to body ground in the wire. Replace the affected shielded harness.
NO
Go to step 9.
- Open wire check (ECALL-NAVI MIC+ line)
-1. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode Front HFL-ANC microphone 8P connector: disconnected Test point 1 Telematics control unit connector A (32P) No. 9 Test point 2 Body ground Is there about 8.0 V?
YES
There is an open in the wire. Replace the affected shielded harness.
NO
The ECALL-NAVI MIC+ wire is not open. Go to step 10.
- Shorted wire check (ECALL-NAVI MIC+ line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connector.
Telematics control unit connector A (32P) -3. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Front HFL-ANC microphone 8P connector: disconnected Telematics control unit connector A (32P): disconnected Test point 1 Telematics control unit connector A (32P) No. 9 Test point 2 Body ground Is there continuity?
YES
There is a short in the wire. Replace the affected shielded harness.
NO
The ECALL-NAVI MIC+ wire is not shorted to ground. Go to step 11.
- Shorted wire check (ECALL-NAVI MIC+ line to ECALL-NAVI MIC- line, SH ECALL-NAVI MIC line)
-1. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Front HFL-ANC microphone 8P connector: disconnected Telematics control unit connector A (32P): disconnected Test point 1 Telematics control unit connector A (32P) No. 9 Test point 2 Telematics control unit connector A (32P) No. 7 Test point 1 Telematics control unit connector A (32P) No. 9 Test point 2 Telematics control unit connector A (32P) No. 8 Is there continuity?
YES
There is a short in the wires. Replace the affected shielded harness.
NO
