ABS TOYOTA CAMRY V20 1986 Service Information

4. The liquid refrigerant is charged by the expansion valve into a low temperature, low pressure liquid and
geseous mixture.
5. This cold and foggy refrigerant flows to the evaporator. Vaporizing the liquid in the evaporator, the heat
from the warm air stream passing through the evaporator core is transfered to the refrigerant.
All the liquid is changed into geseous refrigerant in the evaporator and only heat±laden geseous refrig-
erant is drawn into the compressor. Then the process is repeated again.
GENERAL DESCRIPTION
REFRIGERATION CYCLE
1. The compressor discharges high temperature and high pres-
sure refrigerant containing the heat absorbed from the
evaporator plus the heat created by the compressor in a dis-
charge stroke.
2. This gaseous refrigerant flows into the condenser. In the con-
denser, the gaseous refrigerant condenses into liquid
refrigerant.
3. This liquid refrigerant flows into the receiver which stores and
filters the liquid refrigerant till the evaporator requires the ref±
rigerant.

IF VEHICLE IS EQUIPPED WITH MOBILE
RADIO SYSTEM (HAM, CB, ETC.)
The ECU has been designed so that it will not be affected ±by out-
side interference.
However, if your vehicle is equipped with a CB radio transceiver,
etc. (even one with about 10 W output), it may, at times, have an
affect upon ECU operation, especially if the antenna and feeder are
installed nearby.
Therefore, observe the following precautions:
1. Install the antenna as far as possible from the ECU. The
ECU is located under the radio so the antenna should be installed
at the rear side of the vehicle.
2. Keep the antenna feeder as far away as possible from the
ECU wires ± at least 20 cm (7.87 in.) ± and, especially, do not wind
them together.
3. Check that the feeder and antenna are properly adjusted.
4. Do not equip your± vehicle with a powerful mobile radio system.
5. Do not open the cover or the case of the ECU unless absolutely nec-
essary. (If the IC terminals are touched, the IC
may be destroyed by static electricity.)
AIR INDUCTION SYSTEM
1. Separation of the engine oil dipstick, oil filler cap, PCV hose,
etc. may cause the engine to run out¿¿ tune.
2. Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will allow air suction and cause the engine to run out of tune.
ELECTRONIC CONTROL SYSTEM
1. Before removing EFI wiring connectors, terminals, etc., first discon-
nect the power by either turning the ignition switch
OFF or disconnecting the battery terminals.
2. When installing the battery, be especially careful not to
incorrectly connect the positive (+) and negative (±) cables.
3. Do not permit parts to receive a severe impact during removal or
installation. Handle all EFI parts carefully, especially the ECU.
4. Do not be careless during troubleshooting as there are numerous
transistor circuits and even slight terminal contact can cause fur-
ther troubles.
5. Do not open the ECU cover.
6. When inspecting during rainy weather, take care to prevent
entry of water. Also, when washing the engine compartment, pre-
vent water from getting on the ER parts and wiring connectors.
7. Parts should be replaced as an assembly.

INSPECTION OF FUEL VAPOR
LINES, FUEL TANK AND TANK CAP
1. VISUALLY INSPECT LINES AND CONNECTIONS
Look for loose connections, sharp bends or damage.
2. VISUALLY INSPECT FUEL TANK
Look for deformation, cracks or fuel leakage.
3. VISUALLY INSPECT FUEL TANK CAP
Check if the cap and/or gasket are deformed or damaged if
necessary, repair or replace. the cap.
To reduce HC emission, evaporated fuel from the fuel tank is routed through the charcoal canister to the intake manifold for
combustion in the cylinders.

FRONT WHEEL ALIGNMENT
1. MAKE FOLLOWING CHECKS AND CORRECT ANY
PROBLEMS
(a) Check the tires for wear, size and proper inflation.
Cold tire inflation pressure:
FWD/SV21 and 4WD 2.1 kg±cm2 (30 psi, 206 kPa)
FWD/VZV21 2.2 kg±cm2 (31 psi, 216 kPa)
