STEERING SWITCH
Description
INFOID:0000000005259337
When one of the steering wheel AV control switches is pushed, the resistance in the steering wheel AV control
switch circuit changes depending on which button is pushed.
Diagnosis Procedure
INFOID:0000000005259338
Regarding Wiring Diagram information, refer to
.
1.
CHECK STEERING WHEEL AUDIO CONTROL SWITCH RESISTANCE
1. Disconnect steering wheel audio control switch connector M102.
2. 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-147, "Removal and Installation"
.
2.
CHECK HARNESS
1. Turn ignition switch OFF.
2. Disconnect AV control unit connector M131 and spiral cable
connector M30.
3. Check continuity between AV control unit harness connector
M131 (A) and spiral cable harness connector M30 (B).
4. Check continuity between AV control unit connector 1312 (A) and ground.
Are the continuity results as specified?
YES
