igation System"

.

1.

CHECK AMP ON SIGNAL (BOSE SPEAKER AMP)

1. Turn audio system ON.

2. Check voltage between BOSE speaker amp. harness connector

B109 terminal 20 and ground.

Is inspection result normal?

YES

>> Inspection End.

NO

>> GO TO 2.

2.

CHECK AMP ON SIGNAL (AV CONTROL UNIT)

Check voltage between AV control unit harness connector M160 ter-

minal 1 and ground.

Is inspection result normal?

YES

>> Repair harness or connector.

NO
