INFOID:0000000009471517

Regarding Wiring Diagram information, refer to 

AV-614, "Wiring Diagram - With BOSE audio system With Nav-

igation System"

.

1.

CHECK STEERING WHEEL AUDIO CONTROL SWITCH RESISTANCE

1. Turn ignition switch OFF.

2. Disconnect steering wheel audio control switch connector M88.

3. Check resistance between steering switch connector terminals.

Do the steering wheel audio control switches check OK?

YES

>> GO TO 2.

NO

>> Replace steering wheel audio control switch. Refer to 

AV-667, "Removal and Installation"

.

2.

CHECK HARNESS BETWEEN COMBINATION SWITCH (SPIRAL CABLE) AND AV CONTROL UNIT

1. Disconnect AV control unit connector M160 and combination

switch (spiral cable) connector M30.

2. Check continuity between AV control unit harness connector

M160 (A) and combination switch (spiral cable) harness connec-
