voice recognition. Perform Inspection Procedure 3: When the speech switch 
is pressed, the voice guide is output, but the voice recognition is not 
performed. (Refer to

.)

The hands free-ECU cannot 
recognize the speech voice 
because of noise or others.

Minimize the noise by turning off the A/C, closing the window, and stopping 
the engine, and then clearly speak up near the microphone unit.

The microphone unit , or the

The microphone unit may have a problem. Perform Inspection Procedure 3: 
When the speech switch is pressed, the voice guide is output, but the voice 
recognition is not performed. (Refer to 

P.54A-260

.) The connection with the 

microphone unit can be checked by the microphone check result on the 
diagnosis mode. (Refer to 

P.54A-254

 <Vehicles with 1CD audio> or 

P.54A-256

 <Vehicles with display audio>.)

The speech switch, or the 
connection has a problem.

If the voice guide is not output when the speech switch is operated, the 
speech switch has a problem. Perform the Inspection Procedure 4: When the 
speech switch is pressed, the voice guide is not output. (Refer to

Cause

Solution

The Bluetooth

® connection 

is not made between the 
hands free-ECU and cellular 
phone.

Connect the cellular phone to the hands free-ECU via Bluetooth

®.

The OFF HOOK switch, 
speech switch, or the

sent from the speaker.

Cause

Solution

The hands free-ECU cannot 
receive the vehicle speed 
signal from the radio and CD 
player.

If the vehicle speed signal the hands free-ECU receives has a problem, the 
vehicle speed signal of radio and CD player or the hands free-ECU may have 
a problem. Perform the Inspection Procedure 8: Voice guide "Unable to 
obtain vehicle speed. Please try again or contact your dealer for service" is 
sent from the speaker. (Refer to
