STEERING SWITCH
DescriptionINFOID:0000000001728775
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 ProcedureINFOID:0000000001728776
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 XX-XX, "*****"
.
2.CHECK HARNESS
1. Turn ignition switch OFF.
2. Disconnect AV control unit connector M42 and spiral cable con-
nector M30.
3. Check continuity between AV control unit harness connector
M42 (A) and spiral cable harness connector M30 (B).
4. Check continuity between AV control unit connector M42 (A) and ground.
Are the continuity results as specified?
YES >> GO TO 3
NO >> Repair harness.
