Possible cause	• Connector or terminal malfunction • Short to power supply in wiring harness between Bluetooth^® unit terminal A and microphone terminal A • Microphone malfunction • Bluetooth^® unit malfunction

Diagnostic Procedure

Step	Inspection		Action
1	INSPECT MICROPHONE CONNECTOR STATUS • Switch the ignition off. • Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [MZR 1.6].) • Disconnect the microphone connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is there any malfunctioning part?	Yes	Repair or replace the connector, then go to Step 4.
1		No	Go to the next step.
2	INSPECT Bluetooth^® UNIT CONNECTOR CONDITION • Disconnect the Bluetooth^® unit connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is there any malfunctioning part?	Yes	Repair or replace the connector, then go to Step 4.
2		No	Go to the next step.
3	INSPECT FOR SHORT TO POWER SUPPLY IN MICROPHONE INPUT CIRCUIT • Reconnect all the disconnected connectors. • Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [MZR 1.6].) • Switch the ignition ON (engine off or on). • Measure the voltage of Bluetooth^® unit terminal A (vehicle wiring harness side). • Is the voltage B+?	Yes	If there is a common connector:If there is no common connector: Refer to the wiring diagram and verify whether or not there is a common connector between Bluetooth^® unit terminal A and microphone terminal A. • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. • Repair or replace the malfunctioning part. • Repair or replace the wiring harness which has a short to power supply. Go to the next step.
3		No	Go to the next step.
4	PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS MICROPHONE OR Bluetooth^® UNIT • Perform an inspection of the Bluetooth^® unit DTCs. (See DTC INSPECTION [AUDIO].) • Is the same DTC displayed?	Yes	Replace the microphone, then go to the next step. (See MICROPHONE REMOVAL/INSTALLATION.)
4		No	Go to Step 6.
5	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Perform an inspection of the Bluetooth^® unit DTCs. (See DTC INSPECTION [AUDIO].) • Is the same DTC displayed?	Yes	Replace the Bluetooth^® unit, then go to the next step. (See Bluetooth® UNIT REMOVAL/INSTALLATION.)
5		No	Go to the next step.
6	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [AUDIO].)
6		No	DTC troubleshooting completed.
