INFOID:0000000001450743

1.

CHECK AMP ON SIGNAL (BOSE SPEAKER AMP)

1.

Turn audio system ON.

2.

Check voltage between BOSE speaker amp. harness connector
B75 terminal 31 and ground.

Is battery voltage present?

YES

>> Inspection End.

NO

>> GO TO 2

2.

CHECK AMP ON SIGNAL (AV CONTROL UNIT)

Check voltage between AV control unit harness connector M69 ter-
minal 110 and ground.

Is battery voltage present?

YES

>> Repair harness or connector.

NO

>> Replace AV control unit. Refer to 

AV-266, "Removal and

Installation"
