MICROPHONE SIGNAL CIRCUIT
DescriptionINFOID:0000000001728771
Voice signals are transmitted from the microphone to the AV control unit using the microphone signal circuits.
Diagnosis ProcedureINFOID:0000000001728772
1.CHECK HARNESS BETWEEN AV CONTROL UNIT AND MICROPHONE
1. Turn ignition switch OFF.
2. Disconnect AV control unit connector and microphone connector.
3. Check continuity between AV control unit harness connector M44 and microphone harness connector
R15.
4. Check continuity between AV control unit harness connector M44 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 AV 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 AV control unit. Refer to XX-XX, "*****"
.
3.CHECK MICROPHONE SIGNAL
Check signal between AV control unit harness connector M44 terminals 27 and 28 with CONSULT-III or and
oscilliscope.
