FOREWORD [ENTIRE AUDIO SYSTEM]
Note. Record all radio programs set by customer prior to the repairs. Reset all radio programs and adjust the time after repairs.
CONFIRMATION STEP 1: AUDIO PANEL SWITCH CONFIRMATION
- Make sure to verify the customer complaint and identify if it's either the center panel malfunction or audio unit malfunction.
How to activate audio panel switch confirmation mode
- Turn the audio system to ON.
- Press both POWER SW and MEDIA buttons for a second at the same time.
- The audio panel switch confirmation mode is now activated. DIAGNOSTIC PROCEDURE STEP INSPECTION ACTION 1 Press each button on the center panel. Does buzzer sound when pressing each button? Yes Make sure to confirm the customer complaint and then perform appropriate symptom troubleshooting procedure. No Go to the next step. 2 Disassemble and reassemble the center panel and audio unit. Activate the audio panel switch confirmation mode. Does buzzer sound when pressing each button? Yes Go to the next step. No Replace the center panel. 3 Does the audio system operate properly? Yes The system is normal. No Make sure to confirm the customer complaint and then perform appropriate symptom troubleshooting procedure.
CONFIRMATION STEP 2: AUDIO CONTROL SWITCH CONFIRMATION
- Make sure to verify the customer complaint and identify if it's either the audio control switch malfunction or audio unit malfunction.
| STEP | INSPECTION | ACTION |
|---|
| 1 | Is the symptom related to either the audio control switch or audio panel operation? | Yes | Make sure to verify the customer complaint and then perform appropriate symptom troubleshooting procedure. |
| No | The symptom is related to the audio panel operation: Follow the "Confirmation Step 1". The symptom is related to the audio control switch operation: Go to the next step. |
| 2 | Disconnect the audio unit connector (24-pin). Inspect both the audio unit and wiring harness-side connectors for poor connection, (such as damaged/pulled-out pins, corrosion). Terminal N (ST SW1) Terminal P (ST SW2) Are all the pins normal? | Yes | Go to the next step. |
| No | If the audio unit side connector is wrong: Replace the audio unit. If the wiring harness-side connector is wrong: Repair or replace the pins and/or the connector. |
| 3 | Inspect the continuity between the audio unit wiring harness-side connector terminal N and P while operating the audio control switch. Does the resistance change? | Yes | Make sure to verify the customer complaint and then perform appropriate symptom troubleshooting procedure. |
| No | Go to the next step. |
| 4 | Turn the ignition switch to the LOCK position. Remove the audio control switch. Inspect the continuity between the audio unit wiring harness-side connector (24-pin) terminal and the audio control switch wiring harness-side connector (8-pin) terminal.

3. Stereo and Monaural Receptions
- As signals become weak, noise may appear more in stereo reception. Comparing to stereo reception, noise in monaural receptions is relatively less striking.
Measures in Audio System Separation control
- Utilizing the characteristic of monaural reception that noise is relatively less striking than stereo reception, the audio system automatically changes the reception from stereo to monaural and lessens annoying noise when signals become weak or a multipath phenomenon occurs.
High tone control
- When signals become weak or a multipath phenomenon occurs, the audio system restrains volume level in high frequency band and lessens annoying noise.
Scheme 57
Scheme 57: Effect Setting of Separation Control and High Tone Control
- The separation and high tone controls influence sound quality, Therefore they are specifically tuned for individual model. (Comparison of characteristic must be done on the same models)
Scheme 58
- Signals tend to reach longer distances in the night. It is conspicuous in AM signals, several audio functions may stop due to foreign broadcasting station or noise, though the audio system restrains sensitivity of SEEK and SCAN functions in the night, the audio system may select other than desired broadcasting station when signals are considerably strong. This function is liked to the parking light. When the parking light or headlight is turned on, SEEK and SCAN may not function for weak signals.
Scheme 59
Scheme 59: AUDIO CD [REFERENCE]
- The CD player/changer has been designed to play CDs bearing the identification logo, COMPACT DISC DIGITAL AUDIO, as shown. No other discs can be played on the CD player/changer other than MP3 applicable one.
- The CD player/changer may not play the following CD: Defective CD (e.g., cracked, badly bent, rough edges, scratch, dirty CD condensation) 8 cm (3 in) CDs accessories (e.g., 8 cm (3 in) disc adapter, sticker, label) Nonstandard CD (e.g., Diameter/thickness is out of specification) Specification: 119.7-120.3 mm (4.668-4.692 in) of diameter, 12+0.3 or -0.1 mm (0.047+0.012 or 0.004 in) of thickness
- Do not use non-conventional discs. The CD player/changer could be damaged.
Scheme 60
- Although the same physical size as the compact disc, SACD uses a different kind of digital audio signal, Direct Stream Digital.
- The CD player/changer may not play the CD-R/RW properly due to the disc condition (excluding the MP3).
MP3-Formatted File Outline of CD-R and CD-RW
- Definition CD-R: The CD-R is a non-rewritable version. Once a section of a CD-R is written, it cannot be erased or rewritten. CD-RW: The CD-RW is a re-writable version of CD-ROM and can be written the data an unlimited number of times. Since a reflected laser beam amount of the CD-R/RW is less than the reflected laser beam amount of the conventional CD media, the CD player/changer may not play the CD-R/RW or have the sound jumped. Since the recording quality of the CD-R/RW vary widely, some CD-R/RW may not be played.
- There are two methods for recording.
- Classification by recorder Record the audio data in the audio-CD by audio recorder The price of the audio recorder and original audio-CD includes the copyright fee. Recorded the audio data in the conventional data-CD by the personal computer The data-CD is cheaper than the audio-CD. But, there is a CD with the low quality.
- Classification by audio data uncompression/compression Uncompressed audio data The CD-R/RW player can play the uncompressed audio data. Compressed audio data It is possible to record the large quantity of music in a disc. The sound quality varies depends on the audio data compression format. The compressed audio data can be played on the applicable player only.
- Type of compression format: MP3: MPEG Audio Layer 3 - Mazda genie MP3 applicable CD player is available. WMA: Windows Media Audio ATRAG: Adaptive Transform Acoustic Coding
MP3
- The following condition should be met in order to record the MP3-formatted data on the MP3 applicable CD player
