Diagnostic Procedure

NOTE:

The malfunction may be caused by a non-genuine, after-market electrical component. If a non-genuine, after-market electrical component has been installed and it cannot be determined whether the malfunction cause is due to the non-genuine, after-market electrical component or not, more time may be required to perform the malfunction diagnosis. (See FOREWORD [ENTERTAINMENT SYSTEM [WITH CENTER DISPLAY]] .)

NO NAVIGATION GUIDANCE VOICE OUTPUT (ENTERTAINMENT SYSTEM - WITH CENTER DISPLAY) DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	VERIFY AFTER-MARKET ELECTRICAL COMPONENT INSTALLATION CONDITION Verify if a non-genuine, after-market electrical component is installed. Has a non-genuine, after-market electrical component been installed?	Yes	Go to the next step.
1		No	Go to Step 3.

3		No	Go to the next step.
4	VISUALLY INSPECT SD CARD Switch the ignition off. Visually inspect the SD card for looseness or damage. Is the SD card normal?	Yes	Go to the next step.
4		No	System is normal. (explain to the customer that there is a malfunction in SD card.)
5	INSPECT GPS ANTENNA CONNECTOR Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Disconnect the GPS antenna 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.
5		No	Repair or replace the connector, then go to Step 8.
6	VERIFY IF MALFUNCTION CAUSE IS AUXILIARY JACK/USB PORT/SD CARD SLOT HUB Replace the auxiliary jack/USB port/SD card slot hub. (See AUXILIARY JACK/USB PORT/SD CARD SLOT HUB REMOVAL/INSTALLATION .) Connect all the connectors. Reconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Insert the SD card when the malfunction occurred. Switch the ignition to ACC or ON (engine off or on). Select navigation by operating the center display or the commander switch. Set to an optional destination and operate the navigation function. Is navigation guidance audio output according to the operation?	Yes	Troubleshooting completed. (Explain the contents of the servicing to the customer.)
6		No	Go to the next step.
7	VERIFY IF MALFUNCTION CAUSE IS GPS ANTENNA Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Replace the GPS antenna. (See GLOBAL POSITIONING SYSTEM (GPS) ANTENNA REMOVAL/INSTALLATION .) Connect all the connectors. Reconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Insert the SD card when the malfunction occurred. Switch the ignition to ACC or ON (engine off or on). Select navigation by operating the center display or the commander switch. Set to an optional destination and operate the navigation function. Is navigation guidance audio output according to the operation?	Yes	Troubleshooting completed. (Explain the contents of the servicing to the customer.)
7		No	Replace the CMU, then go to the next step. (See CONNECTIVITY MASTER UNIT (CMU) REMOVAL/INSTALLATION .)
8	VERIFY IF MALFUNCTION CAUSE IS CORRECTED Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Connect all the connectors. Reconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Insert the SD card when the malfunction occurred. Switch the ignition to ACC or ON (engine off or on). Select navigation by operating the center display or the commander switch. Set to an optional destination and operate the navigation function. Is navigation guidance audio output according to the operation?	Yes	Troubleshooting completed. (Explain the contents of the servicing to the customer.)
8		No	Verify the malfunction symptom in the symptom troubleshooting chart and perform the other applicable malfunction diagnosis. (See SYMPTOM TROUBLESHOOTING [ENTERTAINMENT SYSTEM [WITH CENTER DISPLAY]] .)
