1. 

CHECK FUSES

Check that any of the following fuses for voice activated control module is blown.

OK or NG

OK

>> GO TO 2.

NG

>> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to 

PG-

2, "POWER SUPPLY ROUTING"

 .

2. 

CHECK POWER SUPPLY CIRCUIT 

Check voltage between voice activated control module harness con-
nector B69 terminals 13, 20 and ground.

Symptom

Remedy

Displays “COMMAND NOT 
RECOGNIZED” or the sys-
tem does not interpret the 
command correctly.

1. Ensure that the command is valid, see Command list (Refer to Owner’s Manual).

2. Ensure that the command is given after the tone while “ LISTENING” is displayed.

3. Speak clearly without pausing between words and at a level appropriate to the ambient noise level.

4. Ensure that the ambient noise level is not excessive, for example, windows open or defrost on.

NOTE:
If it is too noisy to use the microphone, it is likely that voice commands will not be recognized.

5. If optional words of the command have been omitted, then the command should be tried with these in 

place.

6. If a number of commands have been given in rapid succession resulting in the message “COMMAND 

NOT RECOGNIZED” to be displayed, then allow the system to recover (approximately 1 minute) 
before trying the command again.

7. If the system consistently does not recognize commands, the voice training procedure should be per-

formed to improve the recognition response for the speaker.

Displays “NO SPEECH 
DETECTED”.

1. Ensure that the command is given after the tone while “LISTENING” is displayed.

2. Ensure that the command is given within a maximum of five seconds from the end of the tone.

NOTE:
Be sure you know what to say before pressing the Voice button.

Displays “NAMETAG NOT 
UNIQUE”.

1. This response will be received when storing a nametag if the nametag being given has already been 

stored. This can be confirmed by giving the Radio Directory command.

2. If this response is received and the nametag has not been used already, then it is too similar to an 

existing nametag or voice grammar and an alternative should be used.

The system consistently 
selects the wrong nametag.

1. Ensure that the nametag requested matches what was originally stored. This can be confirmed by 

giving the Radio Directory command.

2. Delete one of the nametags being confused and replace it with a different nametag.
