(b) Matters that require attention when checking:

Noise coming into the radio usually has no harm for
daily use as the noise protection is taken, and it is
very rate for an extremely loud noise to come in.
When extremely loud noise comes into the radio,
check if the grounding is normal where the antenna
is installed.

Check if all the regular noise prevention parts are
properly installed, and if there is any installation of
non-authorized parts and non-authorized wiring.

If you leave the radio under out of tune (not turning),
it is easy to diagnose the phenomenon as noise oc-
curs frequently.
(c) Antenna and noise:
Electronic signal received by the antenna will reach to the
radio transmitting through the core wire of the coaxial
cable. Any noise wave other than radio wave is mixed into
this core wire, that naturally causes noise in the radio and
poor sound quality. In order to prevent the noise from
coming into radio, the core wire inside the coaxial cable
is covered with a mesh wire called shield wire which trans-
mits the noise to the ground.
5. COMPACT DISC PLAYER
Compact Disc Players use a laser beam pick-up to read the dig-
ital signals recorded on the CD and reproduce analog signals
of the music, etc.
HINT:
Never attempt to disassemble or oil any part of the player unit.
Do not insert any object other than a disc into the magazine.
NOTICE:
CD players use an invisible laser beam which could cause
hazardous radiation exposure. Be sure to operate the play-
er correctly as instructed.
6. Tape player/head cleaning:
MAINTENANCE
(a) Raise the cassette door with your finger.
Next, using a pencil or similar object, push in the guide.
(b) Using a cleaning pen or cotton applicator soaked in clean-
er, clean the head surface, pinch rollers and capstans.

7. CD player/disc cleaning:
MAINTENANCE
If the disc gets dirty, clean the disc by wiping the surface from
the center to outside in the radial directions with a soft cloth.
NOTICE:
Do not use a conventional record cleaner or anti-static pre-
servative.
8. OUTLINE OF AVC-LAN
(a) What is AVC-LAN?
AVC-LAN is the abbreviation, which stands for Audio Visual Communication-Local Area Network.
This is a unified standard co-developed by 6 audio manufactures associated with Toyota Motor Corpo-
ration.
The Unified standard covers signals, such as audio signal, visual signal, signal for switch indication
and communication signal. Radio receiver assembly and RSA (Rear Seat Audio) panel have a resis-
tance (60 - 80 W) required for communication.
(b) Objectives
Recently the car audio system has been rapidly developed and functions have been changed drasti-
cally. The conventional system has been switched to the multi-media type such as a navigation sys-
tem. At the same time the level of customers needs to audio system has been upgraded. This lies be-
hind this standardization.
The concrete objectives are explained below.
(1) When products by different manufactures were combined together, there used to be a case that
malfunction occurred such as sound did not come out. This problem has been resolved by stan-
dardization of signals.
(2) Various types of after market products have been able to add or replace freely.
(3) Because of the above (2), each manufacture has become able to concentrate on developing
products in their strongest field. This has enabled many types of products provided inexpensive-
ly.
(4) In general, a new product developed by one particular manufacture could not be used due to
a lack of compatibility with other manufactures products. Because of this new standard, users
can enjoy many compatible products from different manufacture anytime they went.
(c) The above descriptions are the objectives to introduce AVC-LAN. By this standardization, develop-
ment of new products will no longer cause systematic errors.

ON-VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
Maintenance-Free Battery:
If under the lower level, replace the battery (or add distilled wa-
ter if possible). and check the charging system.
Except Maintenance-Free Battery:
If under the lower level, add distilled water.
2. Except Maintenance-Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity:
1.25 - 1.29 at 20°C (68°F)
If the specific gravity is less than specification, charge the bat-
tery.
3. Maintenance-Free Battery:
CHECK BATTERY VOLTAGE
(a) After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c) Measure the battery voltage between the negative (-)
and positive (+) terminals of the battery.
Standard voltage:
12.5 - 12.9 V at 20°C (68°F)
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
(b) Check the fusible link and fuses for continuity.

READINESS MONITOR DRIVE PATTERN
1. PURPOSE OF THE READINESS TESTS

The On-Board Diagnostic (OBD II) system is designed to monitor the performance of emission-re-
lated components and report any detected abnormalities in the form of Diagnostic Trouble Codes
(DTCs). Since the various components need to be monitored during different driving conditions, the
OBD II system is designed to run separate monitoring programs called Readiness Monitors. Many
state Inspection and Maintenance (I/M) programs require that vehicles complete their Readiness Mon-
itors prior to beginning an emissions test.

The current status of the Readiness Monitors can be seen by using the hand-held tester with version
9.0 software (or newer), or a generic OBD II Scan tool.

To view the Readiness Monitor status using the hand-held tester, select ºMonitor Statusº from the En-
hanced OBD II Menu.

A status of ºcompleteº indicates that the necessary conditions have been met to run the performance
tests for the related Readiness Monitor.

The Readiness Monitor will be reset to ºincompleteº if:

ECM has lost power (battery or fuse).

DTCs have been cleared.

The conditions for running the Readiness Monitor have not been met.

In the event that any Readiness Monitor shows ºincomplete,º follow the appropriate Readiness Monitor
Drive Pattern to active the monitor and change the readiness status to ºcomplete.º
CAUTION:
Strictly observe of posted speed limits, traffic laws, and road conditions when performing these
drive patterns.
NOTICE:
These drive patterns represent the fastest method to satisfy all necessary conditions which allow
the specific readiness monitor to complete.
In the event that the drive pattern must be interrupted (possibly due to traffic conditions or other fac-
tors) the drive pattern can be resumed, and in most cases, the readiness monitor will still set to ºcom-
pleteº.
To ensure rapid completion of readiness monitors, avoid sudden changes in vehicle load and speed
(driving up and down hills and/or sudden acceleration).
