Audio System Self-Diagnostic Function




Audio System Self-Diagnostic Function

How to Obtain the Audio Unit Serial Number

To obtain the audio unit serial number on a vehicle, do following:

NOTE:

- This procedure can only be done when the power has been disconnected from the audio unit, and the audio unit displays "ENTER CODE" when the audio unit is turned on.
- If the audio unit does not display "ENTER CODE" when turned on, remove the No. 1 fuse (15A) from the under-dash fuse/relay box for 1 minute, then reinstall the fuse.
- To obtain the audio-navigation unit serial number, refer to ECU info in the navigation system diagnostic mode.

1. Turn the ignition switch to ON (II).

2. Make sure the audio system is turned off.

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

4. While holding the buttons, press the PWR button (Except DX model) or the VOL PUSH PWR knob (DX model) to ON.





5. Release the buttons, and the self-diagnostic function begins (for 20 seconds).

6. The display shows an 8 digit serial number (example 12345678).





7. Use all 8 numbers as the serial number when using the Interactive Network (iN) to retrieve the 4 digit or 5 digit anti-theft code.

8. To end the self-diagnostic function, turn the audio unit off, or turn the ignition switch to LOCK (0). The self-diagnostic function also ends if there is no interaction with the audio unit for 20 seconds.

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:

1. Turn the ignition switch to ON (II).

2. Make sure the audio system is turned off.

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

4. While holding the buttons, press the PWR button (Except DX model) or the VOL PUSH PWR knob (DX model) to ON.

5. Release the buttons, and the self-diagnostic begins.

NOTE: If the display says ENTER CODE, enter the security code and begin again.





6. When you are in the self-diagnostic mode, pressing a preset button starts the diagnostic mode that is assigned to that preset button.

When properly detected, the selected knob, button, or audio remote switch name and/or value is displayed (except PWR button). You cannot exit this test. If you need to check other items with the self-diagnostic function, go to step 7 to exit the self diagnostic function, then start again at step 1.

NOTE: The CD eject button does not work in this test, but when you press it, the CD eject mechanism should hum faintly.

No. 3 button
Entire LCD lighting/light-out mode: Turns on/off the entire LCD to show the presence (LCD stuck on) or absence (LCD dead) of an LCD segment.

No. 4 button
Duty indication mode (for the illumination dim): Indicates the duty for the Illumination dim when the dashlights are on.

No. 5 button
Vehicle speed pulse (VSP) indication mode: Indicates the vehicle speed pulse in hertz (Hz) (Except DX model) and in speed (km/h).

FM/AM button (Except DX model) (Press and hold 5 sec.)
Reception level indication mode: Indicates the reception level (dB) with the antenna amplifier on. Press the
RDM/A.SEL button to turn the antenna amplifier off.

FM button (DX model) (Press and hold 5 sec.)
Reception level indication mode: Indicates the reception level (dB). When entering the reception level check mode, the FM button is used to change the S-METER, OFFSET, MP and USN (A/I).

Canceling the Self-Diagnostic Function

Entry LCD lighting/lights-outs mode (Press No. 3 button)

This diagnostic screen checks for segments that may be dead (off) or stuck on.
All the segments in the display must appear. If there are dead segments, replace the center panel (Except DX model) or audio unit (DX model).
When the display segments are all on, press the No. 3 button. The entire display must turn black. If any segments are stuck on, replace the center panel (Except DX model) or audio unit (DX model).






Illumination level (for the gauge illumination) indication (Press No. 4 button)

This diagnostic screen checks the gauge illumination input.
With the headlights on, you should see a values between 1 (max low) and 22 (max high).
When you dim and brighten the gauge with the dimmer knob, you should see this value change accordingly.






Vehicle speed pulse indication (Press No. 5 button)

This diagnostic screen checks that the audio unit is receiving the VSP indication.
When you drive the vehicle, the VSP indicates the signal from the PCM in hertz (Hz) (Except DX model) and the vehicle speed in km/h.






Reception level indication (Press and hold 5 sec. FM/AM button) (Except DX model)

This diagnostic screen checks the radio reception level. This level then can be used to diagnose the radio reception quality. The reception level is displayed in decibels (dB).

Preparation:

- Park the vehicle outdoors in a location with good radio 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. The AM/FM antenna amplifier is on and the character (A) is not displayed in the audio display.





2. Tune to the FM radio station you wrote down in preparation using the SEEK button (), and note the decibel level of that station.

3. Press and release the RDM/A.SEL button to turn the AM/FM antenna amplifier off (A is now displayed in the audio display).

4. Note the decibel level of that station.

5. Press and release the RDM/A.SEL button to turn the AM/FM antenna amplifier back on (A is not displayed in the audio display).

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 SEEK button (), and note the decibel level of that station.
