STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “1” and “6” simultaneously for 3 seconds.
DIAGNOSIS FUNCTION
The following are checked: All the indicators (LED) in the A/C and AV switch.
 Continuity of the switches by sounding the buzze r when the A/C and AV switch and audio steering wheel
switch is pressed.
 Continuity of harness between A/C and AV switch and audio steering switch.
NOTE:
Rear window defogger switch operation is not checked. (No beep sound even under normal status)
EXITING THE SELF-DIAGNOSIS MODE
 Turn ignition switch OFF.
Trouble DiagnosisINFOID:0000000001328684
 The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.
 The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and oper-
ation of each piece of electrical equipment, and then determine the cause.
 Make sure that other operation except audio system can be performed with A/C and AV switch. If these
operations are inoperative with A/C and AV switch, refer to AV-79, "
Unable to Operate System with A/C and
AV Switch" (Without navigation system), or AV-127, "Unable to Operate System with A/C and AV Switch"
(With navigation system).
 Refer to "SERVICE BULLETIN ITB04-055" for the diagnosis of satellite radio.

Locking CD Auto-Changer MechanismINFOID:0000000001328690
CAUTION:
 Prior to removing a malfunctioning CD auto-changer unit that will be shipped for repair, the changer mechanism MUST BE LOCKED to prevent the mech anism from being damaged during shipping.
 If a CD is jammed or unable to be removed from th e unit, do NOT lock the changer mechanism. If the
unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit.
2. Turn ignition switch OFF. Wait until audio unit display is off and mechanism stops moving (mechanism
sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the audio unit, press the
same disc selection button again within 5 seconds.
 The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism s ound stops), open the driver and passenger window, and
then disconnect negative battery cable.
NOTE:
After installing a new or remanufactured audio unit, switching the audio unit ON will automatically unlock the
mechanism. A special unlocking procedure is not required.
Removal and Installation of Audio UnitINFOID:0000000001328691
REMOVAL

INTEGRATED DISPLAY SYSTEM
System DescriptionINFOID:0000000001328710
For system operation information, refer to Owner's Manual.
INTEGRATED DISPLAY SYSTEM
 Each control unit that comprises the system is connect ed with a communication circuit. It transmits/receives
data signals including request signals and response signals, and controls the system.
 The display control unit transmits/receives data signal s to/from each control unit with CAN communication. It
performs an arithmetical operation on fuel information va lues by using data obtained from the control units,
and then displays the calculated values on the screen.
 The display control unit receives door switch signals from the BCM with CAN communication, and displays a warning on the screen when driving over the set speed with a door half-shut.
 The display control unit receives vehicle speed signal s that are transmitted from the unified meter and A/C
amp., performs an arithmetical operation on drive information values, and then displays the calculated val-
ues on the screen.
 The images displayed on the monitor screen contain display control unit-generated RGB images.
 The display control unit controls image switching and image quality adjustments by communications with the
display.

 Display control unit draws a status of the audio and air conditioner, a TRIP screen, a FUEL ECONOMY screen, etc., and transmits the
image signals to the display screen.
 It receives operation signals of audio and air conditioner from A/C and AV switch, and transmits the operation signal of audio to the
audio unit via the communication line and transmits the operation
signal of air conditioner to the meter and A/C amp. via CAN com-
munication.
DISPLAY
 Images on the display include RGB image such as map screen.
 Display control unit controls images on the display.
A/C AND AV SWITCH
 A/C and AV switch, an integrated combination of audio and air con-ditioner switches, are adopted.
 Operation signal of audio is transmitted to the audio unit through
display control unit with the communication line. Operation signal
of air conditioner is transmitted to meter and A/C amp. through dis-
play control unit with CAN communication.
