ELECTRONIC CIRCUIT INSPECTION
PROCEDURE
1. BASIC INSPECTION
(a) WHEN MEASURING RESISTANCE OF
ELECTRONIC PARTS
(1) Unless otherwise stated, all resistance
measurements should be made at an ambient
temperature of 20
C (68F). Resistance
measurements may be inaccurate if measured
at high temperatures, i.e. immediately after the
vehicle has been running. Measurements should
be made after the engine has cooled down.
(b) HANDLING CONNECTORS
(1) When disconnecting a connector, first squeeze
the mating halves tightly together to release the
lock, and then press the lock claw and separate
the connector.
(2) When disconnecting a connector, do not pull on
the harnesses. Grasp the connector directly and
separate it.
(3) Before connecting a connector, check that there
are no deformed, damaged, loose or missing
terminals.
(4) When connecting a connector, press firmly until
it locks with a "click" sound.
(5) If checking a connector with a TOYOTA
electrical tester, check the connector from the
backside (harness side) using a mini test lead.
NOTICE:
• As a waterproof connector cannot be
checked from the backside, check it by
connecting a sub-harness.
• Do not damage the terminals by moving
the inserted tester needle.
(c) CHECKING CONNECTORS
(1) Checking when a connector is connected:
Squeeze the connector together to confirm that
they are fully connected and locked.
(2) Checking when a connector is disconnected:
Pull the wire harness lightly from the backside of
the connector. Visually check for the following: 1)
unlatched terminals, missing terminals, loose
crimps and broken conductor wires; 2)
corrosion, metallic matter, foreign matter and
water; and 3) bent, rusted, overheated,
contaminated and deformed terminals.

(3) Checking the contact pressure of the terminal:
Prepare a spare male terminal. Insert it into a
female terminal, and check for ample tension
when inserting and after full engagement.
NOTICE:
When testing a gold-plated female terminal,
always use a gold-plated male terminal.
(d) REPAIR METHOD OF CONNECTOR TERMINAL
(1) If there is any foreign matter on the terminal,
clean the contact point using an air gun or cloth.
Never rub the contact point using sandpaper as
the plating may come off.
(2) If there is abnormal contact pressure, replace
the female terminal. If the male terminal is gold-
plated (gold color), use a gold-plated female
terminal; if it is silver-plated (silver color), use a
silver-plated female terminal.
(3) Damaged, deformed, or corroded terminals
should be replaced. If the terminal does not lock
into the housing, the housing may have to be
replaced.
(e) HANDLING OF WIRE HARNESS
(1) If removing a wire harness, check the wiring and
clamping before proceeding so that it can be
restored in the same way.
(2) Never twist, pull or slacken the wire harness
more than necessary.
(3) The wire harness should never come into
contact with a high temperature part, or rotating,
moving, vibrating or sharp-edged parts. Avoid
contact with panel edges, screw tips and other
sharp items.
(4) When installing parts, never pinch the wire
harness.
(5) Ne ver c ut or break th e c ov er of t he w ir e har ness .
If it is cut or broken, repair the cover with vinyl
tape or replace the wire harness.
2. CHECK FOR OPEN CIRCUIT
(a) For an open circuit in the wire harness in Fig. 1,
check the resistance or voltage, as described below.
