REAR DOOR SPEAKER

Description

INFOID:0000000007347914

The AV control unit sends audio signals to the BOSE speaker amp. The BOSE speaker amp. amplifies the

audio signals before sending them to the rear door speakers using the audio signal circuits.

Diagnosis Procedure

INFOID:0000000007347915

Regarding Wiring Diagram information, refer to 

AV-385, "Wiring Diagram - With Navigation System"

.

1.

CONNECTOR CHECK

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. connectors B75 and suspect

speaker connector.

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

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

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

tors B75 (A) and ground.

Are the continuity test results as specified?

YES

>> GO TO 3

NO

>> Repair harness or connector.
