Check the AV control unit, BOSE speaker amp. and speaker connectors for the following:

• Proper connection

• Damage

• Disconnected or loose terminals
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

HARNESS CHECK

1. Disconnect BOSE speaker amp. connector B75 and suspect

speaker connector.

2. Check continuity between BOSE speaker amp. harness connec-

tor B75 (A) and suspect speaker harness connector (B).

3. Check continuity between BOSE speaker amp. harness connec-

tor B75 (A) and ground.

Are continuity test results as specified?

YES

>> GO TO 3.

NO

>> • Check connector housings for disconnected or loose terminals.

• Repair harness or connector.
