INTRODUCTION - Precautions Before Service 13
IKITE ON INSTALLATION OF RADIO EQUIPMW&
The computers of the electronic control system has been
designed so that external radio waves will not interfere with
their operation.
However, if antenna or cable of amateur transceiver etc. is
routed near the computers, it may affect the operation of the
computers, even if the output of the transceiver is no more
than 25W.
To protect each of the computers from interference by
transmitter (hum, transceiver, etc.), the following should be
observed.
1. Install the antenna on the roof.
2. Because radio waves are emitted from the coaxial cable of
the antenna, keep it 200 mm (8 in.) away from the
computers and the wiring harness. If the cable must cross
the wiring harness, route it so that it runs at right angles to
the wiring harness.
3. The antenna and the cable should be well matched, and
the standing-wave ratio* should be kept low.
4. A transmitter having a large output should not be installed
in the vehicle.
5. After installation of transmitter, run the engine at idle, emit
radio waves from the transmitter and make sure that the
engine is not affected.
High-frequency power supply If an antenna and a cable having different impedances are
connected, the input impedance Zi will vary in accordance
with the length of the cable and the frequency of the
transmitter, and the voltage distribution will also vary in
accordance with the location.
The ratio between this maximum voltage and minimum
voltage is called the standing-wave ratio. It can also be
represented by the ratio between the impedances of the
antenna and the cable.
The amount of radio waves emitted from the cable increases
as the standing-wave ratio increases, and this increases the
possibility of the electronic components being adversely
affected.

CONTINUITY AND VOLTAGE TEST FOR CONNEC-
TOR
Following procedures shall be followed for testing continuity and
voltage at connector in order to prevent improper contact and
deterioration of waterproof in connector.
CONVENTIONAL (NON-WATERPROOF) CONNECTOR
Check shall be done by inserting a probing needle from harness
side.
WATER PROOF CONNECTOR
Caution.
Do not insert probing needle from harness side as it will de-
teriorates waterproof and cause for rusting. To inspect the
energized circuit, use the ECI checker.
CHECK FOR IMPROPER ENGAGEMENT OF TERMI-
NAL
When terminal stopper of connector is out of order, engagement
of male and female terminals becomes improper even when con-
nector itself is engaged perfectly and terminal sometimes slips out
to rear side of connector. Ascertain, therefore, that each terminal
does not come off connector by pulling each harness wire.
ENGAGING AND DISENGAGING OF CONNECTOR
TERMINAL
Connector which gives loose engagement shall be rectified by
removing female terminal from connector housing and raise its
lance to establish securer engagement. Removal of connector
housing and raise its lance to establish securer engagement. Re-
moval of connector terminal used for ECI and ELC 4 ,4/l control
circuit shall be done in the following manner.

IDENTIFYING CONNECTORS
In circuit diagrams, the connectors are indicated by symbolic
marks which show the number of their wires and whether they
are male,or female connectors.
(1) Number of connector wires
The number of divisions in the connector diagram indicates
the number of wires. A cross in a division, however, indicates
the position of a guide to prevent improper connection. The
connector shown here, therefore, is a g-wire connector.

(2) Identification of male and female connectors
Connectors drawn with double outer lines are male, and those
with single outer lines are female.
(3) Connector direction
The connector marks show on-vehicle connectors as viewed
from the direction shown here.
(4) Identification of connector terminals
The color codes of a pair of connectors (male and female), if
viewed at their joining surfaces, will appear symmetrical as
illustrated here. When the connectors are connected, their
joining surfaces are put together in the way a book is closed,
so the terminals of identical codes are connected together.
NOTE
The color codes of male and female connectors are not always
identical.
(5) Identification of sealed connectors
Identification of round, sealed connectors (water-proof pin ter-
minal connectors) used in radiator fan motor circuits, turbo
circuits, etc. is accomplished by the same method as
described above.

REMOVAL AND INSTALLATION
INTERMITTENT OPERATION CHECK
(1) Cpnnect the battery and the test light to the relay, as
shown in the figure.
(2) l&ert a variable resistance between terminal 8 and battery
(1) (VR = O-50 kfl)
(3) The condition is normal if, when the battery’s negative (-)
terminal is connected to terminal 7, the test light illumi-
nates at the same time, and thereafter, in accordance with
the value of the variable resistance, stops illumination
(approx. 1.5 sec. - approx. 10.5 sec.) and then illuminates
(approx. 1 sec.) over and over again.
WASHER INTERLOCK OPERATION CHECK
(1) Connect the battery and the test light’ to the relay, as
shown in the .figure.
(2) When terminal 3 is connected to the battery’s negative (-)
terminal, the test light will illuminate approximately 1
s’econd thereafter, and then there will be a release for
a’bout seconds after connecting to the battery’s negative
( - ) terminal.
The condition is normal if about 3 seconds thereafter the
test light stops illumination. (3
