1. CUSTOMER PROBLEM ANALYSIS
In troubleshooting, the problem symptoms must be confirmed accurately and all preconceptions must be
cleared away in order to give an accurate judgment. To ascertain just what the problem symptoms are, it is
extremely important to ask the customer about the problem and the conditions at the time it occurred.
Important Point in the Problem Analysis:
The following 5 items are important points in the problem analysis. Past problems which are thought to be
unrelated and the repair history, etc. may also help in some cases, so as much information as possible should
be gathered and its relationship with the problem symptoms should be correctly ascertained for reference
in troubleshooting. A customer problem analysis table is provided in Diagnostics section for each system
for your use.

2. SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE CHECK
The diagnostic system in the 1999 CAMRY fulfills various functions. The first function is the Diagnostic
Trouble Code Check in which a malfunction in the signal circuits to the ECU is stored in code in the ECU
memory at the time of occurrence, to be output by the technician during troubleshooting. Another function
is the Input Signal Check which checks if the signals from various switches are sent to the ECU correctly.
By using these check functions, the problem areas can be narrowed down quickly and troubleshooting can
be performed effectively. Diagnostic functions are incorporated in the following systems in the CAMRY.

In diagnostic trouble code check, it is very important to determine whether the problem indicated by the diag-
nostic trouble code is still occurring or occurred in the past but returned to normal at present. In addition,
it must be checked in the problem symptom check whether the malfunction indicated by the diagnostic
trouble code is directly related to the problem symptom or not. For this reason, the diagnostic trouble codes
should be checked before and after the symptom confirmation to determine the current conditions, as shown
in the table below. If this is not done, it may, depending on the case, result in unnecessary troubleshooting
for normally operating systems, thus making it more difficult to locate the problem, or in repairs not pertinent
to the problem. Therefore, always follow the procedure in correct order and perform the diagnostic trouble
code check.

A/C COMPRESSOR MAINTENANCE FOR
STORED VEHICLES

Technical Service
BULLETIN
July 21, 2000

When a vehicle is stored for a long period (more than one month), the volume of oil
in the A/C compressor may decrease due to oil flow into the condenser, pipes, etc.
If the A/C system is turned on at high engine RPM after a long storage period, A/C
compressor damage may result.
To minimize the possibility of damage to the A/C compressor while storing a vehicle,
perform the following recommended maintenance procedure at
least once a month to
lubricate the compressor.
Recommended
Maintenance Procedure For A/C Compressor Lubrication:
1. Turn
off A/C and blower switches prior to starting engine.
2. Start and warm±up engine until engine speed drops below 1,000 RPM.
3. Turn on the A/C system (including the rear A/C) using the following settings:
A/C switch: On
Blower Speed: High
Engine Speed: Below 1,000 RPM
4. Keep A/C on with engine idling for at least 30 seconds.
5. Turn off A/C system and stop engine.

TSB
The cassette tape head and capstan should be cleaned regularly to prevent poor sound
quality and/or cassettes from jamming.
The following conditions can easily be avoided by regularly cleaning the head with a tape
cleaner and only using good quality cassettes.
Since the tape head contacts the cassette tape, the tape head accumulates metal oxides
and dirt particles from the tape. In time, a layer of dirt forms on the tape head resulting in
poor transfer of information between the tape and the tape head. This typically causes a
reduction of the higher frequencies or a reduction of the brightness in sound quality.
Tape speed is controlled by the tape capstan and pinch rollers. If the capstan and pinch
rollers accumulate dirt, the tape may slip causing the music to play too fast or too slow.
Dirt can make the capstans sticky, causing the tape to become entangled in the cassette
mechanism. This can cause the cassette to become jammed in the player.
To reduce the occurrence of these conditions, the following approved cassette cleaners are
available through the non±parts system (Material Distribution Center).
