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.

MICROPHONE SIGNAL CIRCUIT
DescriptionINFOID:0000000001728741
Supplies power from NAVI control unit to microphone. The microphone transmits the sound voice to the NAVI
control unit.
Diagnosis ProcedureINFOID:0000000001728742
1.CHECK HARNESS BETWEEN NAVI CONTROL UNIT AND MICROPHONE
1. Turn ignition switch OFF.
2. Disconnect NAVI control unit connector and microphone connector.
3. Check continuity between NAVI control unit harness connector B68 and microphone harness connector
R15.
4. Check continuity between NAVI control unit harness connector B68 and ground.
Are the continuity test results as specified?
YES >> GO TO 2
NO >> Repair harness or connector.
2.CHECK MICROPHONE POWER SUPPLY
1. Connect NAVI control unit connector and microphone connector.
2. Turn ignition switch ON.
3. Check voltage between microphone harness connector R15 ter-
minal 4 and ground.
Is voltage reading approx. 5 volts?
YES >> GO TO 3
NO >> Replace NAVI control unit. Refer to XX-XX, "*****"
.
3.CHECK MICROPHONE SIGNAL
Check signal between NAVI control unit harness connector B68 terminals 8 and 7 with CONSULT-III or oscilli-
scope.
