INFOID:0000000003939107

1.

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 2

NO

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

• Repair harness or connector.
