MICROPHONE SIGNAL CIRCUIT
DescriptionINFOID:0000000003765928
Supply power from NAVI control unit to microphone. The microphone transmits the sound voice to the NAVI
control unit.
Diagnosis ProcedureINFOID:0000000003765929
1.CHECK CONTINUITY BETWEEN NAVI CONTROL UNIT AND MICROPHONE CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect NAVI control unit connector and microphone connector.
3. Check continuity between NAVI control unit harness connector and microphone harness connector.
4. Check continuity between NAVI control unit harness connector and ground.
Is inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK VOLTAGE MICROPHONE VCC
1. Connect NAVI control unit connector.
2. Turn ignition switch ON.
3. Check voltage between NAVI control unit harness connector.
Is inspection result normal?
YES >> GO TO 3.
NO >> Replace NAVI control unit.
3.CHECK MICROPHONE SIGNAL
1. Turn ignition switch OFF.
2. Connect microphone connector.
3. Turn ignition switch ON.
4. Check signal between NAVI control unit harness connector using an oscilloscope.

RELATED TO BASIC OPERATION
RELATED TO HANDS FREE PHONE
 Check that the cellular phone is corresponding type (Bluetooth™ correspond) when the hands free related
malfunction vehicle is in service before performing a diagnosis,.
 There is a case that malfunction occurs due to the version change of the phone type, etc. even though it is a
corresponding type. Therefore, confirm it by changing the cellular phone to another corresponding type
phone, and check that it operates normally. It is necessary to distinguish whether the cause is the vehicle or
cellular phone.
Simple check for Bluetooth™ communication
If cellular phone and NAVI control unit cannot be connected with Bluetooth™ communication, following proce-
dure allows the technician to judge which device has malfunction.
1. Turn on a cellular phone, not connecting Bluetooth
™ communication.
2. Start CONSULT-III, then start Windows
®.
3. Set CONSULT-III near a cellular phone.
4. When operated Bluetooth
™ registration by cellular phone, check
if CONSULT-III
* would be displayed on the device name.
(If other Bluetooth
™ device is located near cellular phone, a
name of the device would be displayed also.)
NOTE:
*:Displayed device name is “NISSAN- ”.
 If no device name is displayed, cellular phone is malfunction.
Repair the cellular phone first, then perform diagnosis.
 If CONSULT-III is displayed on device name, cellular phone is nor-
mal. Perform diagnosis as per the following table.
Symptoms Check items Possible malfunction location / Action to take
Multifunction switch and preset
switch operation does not work. All switches cannot be operated
 “MULTI AV” is displayed on system
selection screen when the CON-
SULT-III is started.Perform CONSULT-III self-diagnosis. Refer to AV- 4 3 4 ,
"CONSULT-III Function (MULTI AV)".
 All switches cannot be operated
 “MULTI AV” is not displayed on sys-
tem selection screen when the CON-
SULT-III is started.AV control unit power supply and ground circuit malfunc-
tion. Refer to AV- 4 6 4 , "

Procedure".
Only specified switch cannot be operat-
ed.Multifunction switch or preset switch malfunction.
Replace multifunction switch or preset switch.
For multifunction switch, refer to AV- 6 5 9 , "
Removal and
Installation".
For preset switch, refer to AV- 6 6 0 , "
Removal and Instal-
lation".
Fuel economy display, vehicle set-
ting operation is abnormal.There is malfunction in the CONSULT-
III self-diagnosis result.Perform detected DTC diagnosis.
There is no malfunction in the self-diag-
nosis results.Ignition signal circuit malfunction.
Refer to AV- 4 6 4 , "
AV CONTROL UNIT : Diagnosis Pro-
cedure".
Guide sound is not heard.On the setting display select “system
sound (guide sound volume, etc.),” and
confirm that guide sound is ON.Voice guidance signal circuit malfunction.
