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
1. Perform damper lock operation. Refer to AV-41, "Locking CD Auto-Changer Mechanism".
2. Remove cluster lid C. Refer to IP-10
.
3. Remove screws (6) with power tool, and remove audio unit with display and unified meter and A/C amp. from instrument panel.
4. Remove screws and remove audio unit.

On Board Self-Diagnosis FunctionINFOID:0000000001328752
DESCRIPTION
Trouble diagnosis function of navigation system has a Self Diagnosis mode by automatic operation and a
Confirmation/Adjustment mode by manual operation.
Self Diagnosis mode checks for connec tions between the units constituting this system, analyzes each indi-
vidual unit at the same time, and displays the results on the display.
Confirmation/Adjustment mode displays trouble diagnos is that require an operation and a judgment by a
human (auto-decision cannot be performed by the system), confirmation of preset value, and an error his-
tory.
