AV-226, "Wiring Diagram - Without Navigation System"

.

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.
