SYSTEM DIAGRAM

AUDIO SYSTEM

The audio system consists of the following components
• Audio unit
• Front tweeters
• Front door speakers
• Rear door speakers
• USB interface
• AUX in jack
• Steering switches
• Antenna base (rod antenna, antenna amp. and satellite antenna)
When the audio system is on, AM/FM signals received by the rod antenna are amplified by the antenna amp.
and sent to the audio unit. The audio unit then sends audio signals to the front tweeters, front door speakers
and rear door speakers.
Refer to Owner's Manual for audio system operating instructions.

HANDS-FREE PHONE SYSTEM

• Bluetooth

control is built into audio unit.

• The connection between cellular phone and audio unit is performed with Bluetooth

communication.

• The voice guidance signal is input from the audio unit and output to the front speakers when operating the

cellular phone.

When A Call Is Originated

• Spoken voice sound output from the microphone (microphone signal) is input to audio unit.
• Audio unit outputs to cellular phone with Bluetooth

communication as a TEL voice signal.

• Voice sound is then heard at the other party.

When Receiving A Call

• Voice sound is input to own cellular phone from the other party.
• TEL voice signal is input to audio unit by establishing Bluetooth

communication from cellular phone, and

the signal is output to front speakers.

SPEED SENSITIVE VOLUME SYSTEM

Volume level of this system goes up and down automatically in proportion to the vehicle speed. The control
level can be selected by the customer. Refer to Owner's Manual for operating instructions.

[DISPLAY AUDIO]

Self diagnosis screen is displayed. The bar graph visible in center of screen indicates progress of self
diagnosis.

Diagnosis results are displayed after the self diagnosis is com-
pleted. The unit names and the connection lines are color coded
according to the diagnostic results.

1: Control unit (audio unit) is displayed in red.

• Replace audio unit if Self Diagnosis did not run because control unit malfunction is indicated. The symptom is audio unit internal

error. Refer to

AV-114, "Removal and Installation"

• If multiple errors occur at the same time for a single unit, the screen switch colors are determined according to the following order

of priority: red > gray.

Comments of self diagnosis results can be viewed in the diagno-
sis result screen.

Error History

The self diagnosis results are judged depending on whether any error occurs from when Self Diagnosis is
selected until the self diagnosis results are displayed.
However, the diagnosis results are judged normal if an error has occurred before the ignition switch is turned
ON and then no error has occurred until the self diagnosis start. Check the Error Record to detect any error
that may have occurred before the self diagnosis start because of this situation.
The frequency of occurrence is displayed in a count up manner. The actual count up method differs depending
on the error item.

Count up method A

• The counter is set to 40 if an error occurs. 1 is subtracted from the counter if the condition is normal at a next

ignition ON cycle.

• The counter lower limit is 1. The counter can be reset (no error record display) with the Delete log switch.

Count up method B

• The counter increases by 1 if an error occurs when ignition switch is ON. The counter will not decrease even

if the condition is normal at the next ignition ON cycle.

• The counter upper limit is 50. Any counts exceeding 50 are ignored. The counter can be reset (no error

record display) with the Delete log switch.

Error item
Some error items may be displayed simultaneously according to the cause. If some error items are displayed
simultaneously, the detection of the cause can be performed by the combination of display items
