Trouble Diagnoses 

AKS004ED

THIS CONDITION IS NOT MALFUNCTION 
Example of Basic Operational Errors

The system should respond correctly to all voice commands. Follow the solutions given in this guide for the
appropriate error when any of the following symptom is encountered.
Where the solutions are listed by number, try each solution in turn, starting with number one, until the symp-
tom is resolved.

Self-Diagnosis Function

AKS004EE

DESCRIPTION 

●

Diagnosis function consists of the self-diagnosis mode, and the “CONFIRMATION/ADJUSTMENT” mode.

●

Self-diagnosis mode checks for connection between AV and NAVI control unit (with navigation system) or
AV control unit (without navigation system) and voice activated control module and analyzes each unit,
then displays the results.

●

“CONFIRMATION/ADJUSTMENT” function analyzes each microphone.

DIAGNOSIS ITEM 

Self-Diagnosis Mode

AKS004EF

OPERATION PROCEDURE

●

To start the self-diagnosis mode and to check the diagnosis result, refer to 

AV-69, "Self-Diagnosis Mode"

(with navigation system), or 

DI-113, "Self-Diagnosis Mode"

  (without navigation system).

Symptom

Remedy

Displays “COMMAND 
NOT RECOGNIZED” or 
the system 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 one minute) 
before trying the command again.

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

out 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 PTT switch.

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 exist-

ing 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.
