Audio System Self-Diagnostic Function

How to Check the Audio System Condition

The audio system has a self-diagnostic function to help find problems with the audio system. To run the self-diagnostic function, do the following:

NOTE:

	Check the vehicle battery condition first.
	Not all self-diagnostic functions appear on all models.
	There may be other self-diagnostic functions that are for factory use only.
	The self-diagnostic function does not find every problem with the audio system.

1.	Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

2.	Make sure the audio menu appears on the screen.

3.	Make sure the audio system is turned off.

4.	Press and hold the preset No. 1 and No. 6 buttons.

5.	While holding the buttons, push the VOLUME/POWER knob.

6.	Release the buttons, and the self-diagnosis begins.

When you are in the self-diagnostic mode, pressing a preset button starts the diagnostic mode that is assigned to that preset button. To exit this mode, go to step 8. Once you exit this test, you must start again at step 1.

	No. 1 button: ANC/active sound control system check mode
	No. 2 button: Audio button, knob, and audio remote switch detection mode
	No. 3 button: Duty indication mode (for the audio panel button illumination dim)
	No. 4 button: Duty indication mode (for the gauge illumination dim)
	No. 5 button: Vehicle speed pulse (VSP) indication mode
	No. 6 button (Press and hold): In Line Diag mode
	FM/AM button (Press and hold 5 sec): Reception level indication mode
	AUX button (Press and hold 5 sec): PANDORA function ON/OFF mode
	MENU button: Camera mode

8.	To end the self-diagnostic mode, turn the audio system off, turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

ANC/Active Sound Control System Check Mode (press No. 1 button)

With the engine stopped, and while in diagnosis, turn the ANC ON to OFF by pressing the No. 1 button. A low frequency hum (50 Hz) should sound for about a minute.

	If the hum does not sound, check for an open in the wire between the ANC/active sound control unit and the audio unit.
	If the hum sounds for a second, check for an open in the wire between ANC/active sound control unit and the microphone.

Audio Button, Knob, and Audio Remote Switch Detection Mode (press No. 2 button)

This diagnosis allows you to manually check all the audio switch panel buttons and knobs, and the audio remote switch buttons. When the button, the knob, or the switch is properly detected, the name or value of the input appears on the display.

NOTE: The POWER button does not support this diagnosis.

Illumination Level (for the Audio Panel Button Illumination) Indication (press No. 3 button)

This diagnostic screen checks the audio panel button illumination input.

Use the SELECT knob to dim and brighten the audio panel button. You should see the value change from 1 (max low) to 22 (max high).

Display Message	Vehicle Test Condition	Remarks
ILL 22	Audio panel button brightness is max high	The illumination value changes from 22 (max high) to 1 (max low)

Illumination Level (for the Gauge Illumination) Indication (press No. 4 button)

This diagnostic screen checks the gauge illumination input.

With the headlights on, use the dimmer knob to dim and brighten the gauge. You should see the value change from 1 (max low) to 21 (max high). If it does not change, go to Audio panel button illumination does not work troubleshooting or Multi-information display or touch screen does not dim or brighten with dimmer troubleshooting.

Display Message	Vehicle Test Condition	Remarks
21	Headlights switch is in parking light position and dashlights brightness is max high	The illumination value changes from 21 (max high) to 1 (max low) (depends on the dash brightness)

Vehicle Speed Pulse Indication (press No. 5 button)

This diagnostic screen checks that the audio unit is receiving the VSP indication.

When you test drive the vehicle, the VSP indicates the vehicle speed pulse.

Display Message	Vehicle Test Condition	Remarks
VSP 0	When the vehicle is stopped.

Factory Diagnostic Screen In Line Diag (press and hold No. 6 button)

NOTE: If the vehicle left the factory in the factory diagnostic mode, you will see this screen every time you turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode. You may also see this screen if you recently replaced the multi-information display unit.

When the multi-information display unit is powered up for the first time at the factory or sometimes when a remanufactured multi-information display unit is installed, the factory diagnostic screen (In Line Diag) appears. Normally the factory does the steps necessary to verify proper operation and terminate the factory diagnosis. Until the proper confirmation sequence is done, the screen appears every time the vehicle is started.

Follow these steps to prevent the screen from appearing in the future:

1.	Press and hold the No. 6 audio preset button to change the In-Line Diag function from "Incomplete" to "Complete".

2.	Turn the vehicle OFF, then back ON to confirm the In-Line Diag screen does not appear again.

The In Line Diag function runs automatically. When the diagnosis finishes, the icons turn different colors based on their test status.

Icon Colors	Description
Green	The system ran a diagnosis and the results are OK.
Red	Errors that require replacement of hardware or harness.
Yellow	Errors that do not require hardware replacement, such as a missing optional systems (rearview camera).
White	The diagnosis is running. The screen functions are locked out while the diagnosis runs.

Reception Level Indication Mode (press and hold FM/AM button for 5 sec)

This diagnostic screen checks the audio unit's reception level in decibels (dB). You can use this reception level to help diagnose audio unit reception quality.

Display Message	Vehicle Test Condition	Remarks

A 123	Antenna power supply (ANT +B) is off.	A is displayed on the display

Preparation:

	Park the vehicle outside in a good location away from tall buildings, mountains, high-voltage power lines or any other object that may interfere with reception.
	Tune to a powerful local FM radio station then write down the radio station number.
	Tune to a powerful local AM radio station then write down the radio station number.

1.	Enter the reception level indication mode in the self-diagnostic function.

2.	Tune to the FM radio station you wrote down in Preparation using the tuning button, and note the decibel level of that station when you release the button.

3.	Press and release the MENU button to turn the AM/FM antenna amplifier off.

4.	Note the decibel level of that station with the AM/FM antenna amplifier off.

5.	Press and release the MENU button to turn the AM/FM antenna amplifier back on.

6.	Press and hold the FM/AM button for more than 5 seconds to enter the AM reception mode.

7.	Tune to the AM radio station you wrote down in preparation using the tuning button, and note the decibel level of that station.

8.	Press and release the MENU button to turn the AM/FM antenna amplifier off.

9.	Note the decibel level of that station with the AM/FM antenna amplifier off.

10.	Press and release the MENU button to turn the AM/FM antenna amplifier back on.

11.	To end the self-diagnostic mode, turn the audio system off, turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

Compare your results to a known-good, (make sure it is the same year and trim level) in the same location and direction, and under the same environmental conditions.

	If the reception level is within 10 % of the known-good vehicle, no repair is needed at this time.
	If the reception level is at least 10 % less than the known good vehicle, go to Poor AM or FM radio reception or interference troubleshooting.
