• Switch the ignition to ACC or ON (engine off or on).
• Select the following by operating the commander switch or the center display.
• Does the language set to the connectivity master unit (CMU) match the language used in voice operations?
|
Yes
|
Go to the next step.
|

• Switch the ignition to ACC or ON (engine off or on).
• Operate the command switch or center display and verify if sound is output from the following modes.
• Is sound output?
|
Yes
|
Tuner and amp unit (TAU) is normal. Go to the next step.
|
No
|
Perform malfunction diagnosis according to NO SOUND OUTPUT IN MULTIPLE MODES.
|

6
|
DETERMINE IF MALFUNCTION IS MICROPHONE RELATED
• Switch the ignition to ACC or ON (engine off or on).
• Launch the on-board diagnostic assist function.
• Select assist code “61”.
• Press ENTER.
• Say, “AM” into the microphone in a normal or slightly loud voice.
• When speaking, verify if the “Microphone” item is displayed.
• Is the “Microphone” item displayed?
|
Yes
|
The microphone is normal. Go to Step 11.
|
No
|
Go to the next step.
|

7
|
MICROPHONE CONNECTOR INSPECTION
• Switch the ignition off.
• Disconnect the negative battery terminal.
(Refer to the [NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION] in the workshop manual.)
• Disconnect the microphone connector.
• Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
• Is the connector normal?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector, then go to Step 12.
|
||
8
|
VERIFY IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN CONNECTIVITY MASTER UNIT (CMU) AND MICROPHONE
• Switch the ignition off.
• Disconnect the connectivity master unit (CMU) connector.
• Verify that the microphone connector is disconnected.
• Inspect the wiring harness for continuity between the following terminals (vehicle wiring harness side).
• Is there continuity?
|
Yes
|
Go to the next step.
|
No
|
Refer to the wiring diagram and verify if there is a common connector between the following terminals.
• Connectivity master unit (CMU) terminal 1P—Microphone terminal E*1/F*2
• Connectivity master unit (CMU) terminal 1R—Microphone terminal D
• Connectivity master unit (CMU) terminal 1S—Microphone terminal A
• Connectivity master unit (CMU) terminal 1T—Microphone terminal B
If there is a common connector:
• Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open circuit to determine the malfunctioning location.
• Repair or replace the malfunctioning location.
If there is no common connector:
• Repair or replace the wiring harness which has an open circuit.
Go to Step 12.
|
||
9
|
VERIFY IF MALFUNCTION CAUSE IS SHORT CIRCUIT TO GROUND IN WIRING HARNESS BETWEEN CONNECTIVITY MASTER UNIT (CMU) AND MICROPHONE
• Verify that the connectivity master unit (CMU) and microphone connectors are disconnected.
• Inspect for continuity between the microphone terminal E*1/F*2 (vehicle wiring harness side) and body ground.
• Is there continuity?
|
Yes
|
Refer to the wiring diagram and verify if there is a common connector between connectivity master unit (CMU) terminal 1P and microphone terminal E*1/F*2.
If there is a common connector:
• Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to ground to determine the malfunctioning location.
• Repair or replace the malfunctioning location.
If there is no common connector:
