The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.
These commands include navigation touch screen and hard button signals, audio/XM selections by voice, and XM
station and music title names. Because the entire bus is daisy chained between components (see diagram), any open
or short in the GA-Net bus harness will cause any or all of these functions to become inoperative. The addition of any
audio accessory must maintain the continuity of the GA-Net bus by installing the Y cable included with the accessory
kit.

Serial Number Display Mode
Eight digits of the serial number (example 12345678)
23-23
Self-diagnostic Function
A
The audio system has a self-diagnostic function.
To obtain the audio unit serial number on a vehicle, do the following:
NOTE: This procedure can only be performed when the battery power is disconnected from the audio unit and the audio unit displays CODE.
 To obtain the navigation unit serial number, refer to Navi ECU in the navigation system diagnostic mode (see page 23-135).
1. Turn the ignition switch to ON (II).
2. Make sure the audio system is turned off.
3. Push and hold the preset No. 1 and No. 6 buttons.
4. While holding the buttons, push the VOL PUSH PWR knob (A) to ON.
5. Release the buttons and the self-diagnostic begins.
6. The display shows a 8 digit serial number.
7. Use all 8 numbers as the serial number when using the Interactive Network (iN) to retrieve the 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).

minute. Change the test speaker by pushing the SKIP button. If you find a speaker(s) with no sound, check the
speaker and harness connections. If the connections are good, replace the speaker, and retest.
10. To end the self-diagnostic function, turn the audio unit off, or turn the ignition switch to LOCK (0).

Reception level indication mode
Preperation:
23-26Audio System
Self-diagnostic Function (cont’d)
This diagnostic screen checks the audio unit’s reception l
evel. This level then can be used in the diagnosis of audio
unit reception quality. The reception level is displayed in decibels (dB)
 Pank the vehicle outdoors in an appropriate location for good radio reception.
 Tune to a powerful local FM radio station then write down the radio station number. 1. Enter the reception level indication mode in the self-dia gnostic function. The AM/FM antenna amplifier is on
(A. SEL or TP is not displayed in the audio-HVAC display).
2. Tune to the FM radio station you wrote down preperation using the T UNING knob, and note the decibel level of
that station when you release the button.
3. Press and release the A. SEL button to turn the AM/FM antenna amplifier off (A. SEL or TP is now displayed in the audio-HVAC display).
4. Tune to the FM radio station you wrote down in preperation using the T UNING knob, and note the decibel level of
that station when you release the button.
5. Press and release the A. SEL button to turn the AM/FM antenna amplifier back on (A. SEL or TP is not displayed in the audio-HVAC display).
6. Turn the ignition switch to LOCK (0) or audio unit off to exit the test mode.
7. 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.

Symptom Troubleshooting

NOTE:
 Check the vehicle battery condition first.
 Check for aftermarket accessories plugged into the vehicle accessory power sockets (including cell
phone).
 Check the connectors for poor connections or loose terminals.
 Check the radio reception in an open area. Compare it to a known-good vehicle when ever possible.Poor
reception/interference can be caused by the
following:
– The radio station is far away.
– Atmospheric conditions are unfavorable.
– Tall buildings, mountains, or high-voltage power lines are nearby.
– Aftermarket metallic wi ndow tint.
1. Turn the ignition switch to ON (II).
2. Do the seek stop test (see page 23-78).
Multipath interference or weak station.
Operation is normal. Go to step 3.
3. Check if the radio reception/interference is the same in several locations.
Go to step 4.
Multipath interference or weak station.
Operation is normal.
4. Start the engine.
5. Check the reception/interference.
Check the antenna and radio grounds. If OK,
check the charging system and the ignition
system. Go to step 6.
6. Turn the ignition switch to LOCK (0). 7. Remove the right side C-pillar trim (see page 20-75).
8. Check the connections from the AM/FM antenna
amplifier to the window antenna.
Repair the connections, or substitute a
known-good AM/FM antenna amplifier and retest.
If the symptom/condition goes away, replace the
original AM/FM antenna amplifier (see page 23-87).
Go to step 9.
9. With the help of an assistant inside the vehicle, have the assistant shine a flashlight (A) along each
antenna wire (B). Check from the outside of the
vehicle for any breaks or openings in the antenna
wires (the light shines through).
Repair the window antenna. Go to AM/FM
antenna repair (see page 23-87), or replace the rear
window (see page 20-47).
Go to step 10.
