3. Remove the changer for repair.
Testing magazines and discs
1. Confirm discs are installed correctly into the magazine (not upside down).
2. Visually inspect/compare the customer's discs with each other and other discs.
Identify any of the following conditions:
IDiscs with a large outside diameter. [Normal size is 120 mm (4.72 in).]
IDiscs with rough or lipped edges.
IDiscs with excessive thickness [Normal size is 1.2 mm (0.047 in).]
IDiscs with scratches, abrasions, or pits on the surface.
IDiscs with grease/oil, fingerprints, foreign material.
IDiscs are warped due to excessive heat exposure.
3. Slide/place the discs in and out of the various magazine positions.
Identify any discs and/or positions that require additional force for placement/ejection. If interference
(sticking, excessive tensions) is found, replace the magazine or the discs.
Note:
IDiscs which are marginally out of specification (ex. dirty, scratched and so on) may play correctly
on a home stereo.
However, when used in the automative environment skipping may occur due to the added vehicle
movement and/or vibration due to road conditions. Autochangers should not be replaced when
discs are at fault.
IUse a soft damp cloth to wipe the discs starting from the center outward in radial direction. Never
use chemical cleaning solutions to clean the discs.

Precautions for Multiport Fuel Injection System
or Engine Control System
1. Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM (Engine Control
Module):
Turn ignition switch to ªOFFº position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
2. Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure to eliminate danger.
3. Be careful not to jar components such as control unit and air
flow meter.
Precautions for Catalyst
If a large amount of unburned fuel enters the converter, the con-
verter temperature will rise to excessively high values. To prevent
this, follow the procedure below:
1. Use unleaded gasoline only. Leaded gasoline will seriously
damage the catalytic converter.
2. When checking for ignition spark or measuring engine
compression, perform tests quickly and only when necessary.
3. Do not run engine when the fuel tank level is low, as a result
the engine may misfire causing damage to the converter.
4. Do not place the vehicle on inflammable material. Keep inflam-
mable material off the exhaust pipe.
Precautions for Turbocharger
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean
supply of oil flowing through the turbocharger and to follow all
required maintenance instructions and operating procedures.
For proper operation of the system, follow the procedure below:
1. Always use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
2. Avoid accelerating engine to a high rpm immediately after start-
ing.
3. If engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting it off.

HFC-134a (R-134a) Service Tools and
Equipment
It is important to understand that HFC-134a (R-134a) refrigerant, and the specified lubricant which must be
used with HFC-134a (R-134a), must never be mixed with CFC-12 (R-12) refrigerant and/or the CFC-12 (R-12)
lubricant.
This means that separate and non-interchangeable service equipment must be used for handling each type
of refrigerant/lubricant.
To prevent the mixing of refrigerants/lubricants, refrigerant container fittings, service hose fittings, and service
equipment fittings (equipment which handles refrigerant and/or lubricant) are different between CFC-12 (R-12)
and HFC-134a (R-134a).
Adaptors to convert from one size of fitting to another must never be used: refrigerant/lubricant contamination
will occur and compressor failure will result.

Maintenance of Oil Quantity in Compressor
The oil used to lubricate the compressor circulates through the
system with the refrigerant. Whenever any component of the sys-
tem is replaced or a large amount of gas leakage occurs, add oil
to the compressor to maintain the specified amount.
If oil quantity is not maintained properly, the following malfunctions
may result:
ILack of oil: May lead to a seized compressor
IExcessive oil: Inadequate cooling (thermal exchange impeded)
Checking and Adjusting
Adjust the oil quantity according to the flowchart shown below.

Can oil return operation be performed?
IA/C system works properly.
IThere is no evidence of a large amount
of oil leakage.

Perform oil return operation, proceeding as follows:
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Start engine, and set the following conditions:

2. Perform oil return operating for about 10 minutes.
3. Stop engine.
CAUTION:
If excessive oil leakage is noted, do not perform the oil return operation.
Should the compressor be replaced?
No Yes

After replacing any of the following major components of the system, be sure
to add the correct amount of oil to the system.
Amount of oil to be added
*1: If compressor is replaced, addition of oil is included in the flow chart.
*2: If refrigerant leak is small, no addition of oil is needed. ªRatioº in this table
indicates the ratio of added oil to the overall amount of oil needed in the
system.
