harness connector M164 (B) terminal 76.

4. Check continuity between auxiliary input jack harness connector M209 (A) terminal 8  and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK AUX IMAGE SIGNAL

1. Connect auxiliary input jack connector M209 and AV control unit connector M164.

2. Turn ignition switch ON.

3. Check signal between auxiliary input jack connector M209 terminal 7 and ground.

Is the inspection result normal?

YES

>> Replace AV control unit. Refer to 

AV-652, "Removal and Installation"

 .

NO

>> Check that there is no malfunction in the external device.

DISK EJECT SIGNAL CIRCUIT

Description

INFOID:0000000009471500

The eject signal is output to AV control unit when the eject switch of A/C and AV switch assembly is pressed.

Diagnosis Procedure

INFOID:0000000009471501

Regarding Wiring Diagram information, refer to 

AV-614, "Wiring Diagram - With BOSE audio system With Nav-

igation System"

.

1.

CHECK CONTINUITY DISK EJECT SIGNAL CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect A/C and AV switch assembly connector M98 and AV

control unit connector M164.

3. Check continuity between A/C and AV switch assembly connec-

tor M98 (A) terminal 14 and AV control unit harness connector

M164 (B) terminal 82.

4. Check continuity between A/C and AV switch assembly connec-

tor M98 (A) terminal 14 and ground.

Are continuity results as specified?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK AV CONTROL UNIT VOLTAGE 

1. Connect A/C and AV switch assembly connector M98 and AV

control unit connector M164.

2. Turn ignition switch ON.

3. Check voltage between AV control unit harness connector M164

terminal 82 and ground.

Are voltage readings as specified?

YES

>> Replace A/C and AV switch assembly. Refer to 

AV-654, "Removal and Installation"

.

NO

>> Replace AV control unit. Refer to 

AV-652, "Removal and Installation"

MICROPHONE SIGNAL CIRCUIT

MICROPHONE SIGNAL CIRCUIT

Description

INFOID:0000000009471502

Voice signals are transmitted from the microphone to the AV control unit using the microphone signal circuits.

Diagnosis Procedure

INFOID:0000000009471503

Regarding Wiring Diagram information, refer to 

AV-614, "Wiring Diagram - With BOSE audio system With Nav-

igation System"

.

1.

CHECK HARNESS BETWEEN AV CONTROL UNIT AND MICROPHONE
