ELECTRONIC CIRCUIT INSPECTION PROCEDURE
1. BASIC INSPECTION
(a) RESISTANCE MEASURING CONDITION OF ELECTRONIC PARTS (1) Unless stated, all resistance is measured at an ambient temperature of 20 C (68 F). As the re-
sistance may be outside the specifications if measured at high temperatures imme\
diately after
the vehicle has been running, measurements should be made when the engine h\
as cooled
down.
(b) HANDLING OF CONNECTOR(1) When removing the connector with lock, press the
connector in the direction of the engagement and
remove the lock by lightly pressing the lock claw.
(2) When removing the connector, do not hold the har- ness, but hold the connector.
(3) Before connecting the connector, check that there is no deformation, damage or missing terminals.
(4) The connector with a lock should be securely con- nected until it makes a ºclickº sound.
(5) When checking the connector with a Toyota electri- cal tester, check it from the backside (harness side)
of the connector using a mini test lead.
NOTICE:
As a water proof connector cannot be checked from
the backside, check by connecting the sub±harness.
Do not damage the terminals by moving the inserted
tester needle.
(c) CONNECTOR CHECKING POINTS
(1) Checking when the connector is connected:By holding the connector, check the inserted condi-
tion and locking efficiency (engaged condition).
(2) Checking when the connector is removed: Check by lightly pulling the wire harness (missing
terminal, terminal crimping condition, core wire
break).
Check visually for any rust, metal particles, water
and bent terminals (rust, mixing of foreign object,
terminal deformation).
NOTICE:
When testing a gold±plated female terminal, always use a
gold±plated male terminal.

(b) Check the continuity. (1) Disconnect connectors A and C and measure theresistance between them.
Resistance: 1 or less
HINT:
Measure the resistance while lightly shaking the wire harness
vertically and horizontally. In the case of Fig. 2:
Between terminal 1 of connector A and terminal 1
of connector C No continuity (open)
Between terminal 2 of connector A and terminal 2
of connector C Continuity
Therefore, the cause is an open circuit between ter-
minal 1 of connector A and terminal 1 of connector
C.
(2) Disconnect connector B and measure the resis-
tance between the connectors.
In the case of Fig. 3:
Between terminal 1 of connector A and terminal 1
of connector B1 Continuity
Between terminal 1 of connector B2 and terminal 1
of connector C No continuity (open)
Therefore, the cause is an open circuit between ter-
minal 1 of connector B2 and terminal 1 of connector
C.
(c) Check the voltage. (1) In a circuit in which voltage is applied (to the ECUconnector terminal), an open circuit can be checked
by conducting a voltage check.
As shown in Fig. 4, with each connector still con-
nected, measure the voltage between the body
ground and terminal 1 of connector A at the ECU 5
V output terminal, terminal 1 of connector B, and
terminal 1 of connector C, in that order.
(2) If the results are: 5 V: Between terminal 1 of connector A and body
ground
5 V: Between terminal 1 of connector B and body
ground
0 V: Between terminal 1 of connector C and body
ground
Therefore, the cause is an open circuit in the wire
harness between terminal 1 of connector B and ter-
minal 1 of connector C.

3. CHECK SHORT CIRCUIT
(a) If the wire harness is ground shorted as shown in Fig. 5,
locate the section by conducting a continuity check with
the body ground in step (b).
(b) Check the continuity with the body ground. (1) Disconnect connectors A and C and measure the
resistance between terminals 1 and 2 of connector
A and the body ground.
Resistance: 10 k or higher
HINT:
Measure the resistance while lightly shaking the wire harness
vertically and horizontally.
In the case of Fig. 6:
Between terminal 1 of connector A and body
ground Continuity (short)
Between terminal 2 of connector A and body
ground No continuity
Therefore, the cause is a short circuit between ter-
minal 1 of connector A and terminal 1 of connector
C.
(2) Disconnect connector B and measure the resis- tance between terminal 1 of connector A and the
body ground, and terminal 1 of connector B2 and
the body ground.
In the case of Fig. 7:
Between terminal 1 of connector A and body
ground No continuity
Between terminal 1 of connector B2 and body
ground Continuity (short)
Therefore, the cause is a short circuit between ter-
minal 1 of connector B2 and terminal 1 of connector
C.

SYMPTOM SIMULATION
HINT:
The most difficult case in troubleshooting is when no symptoms occurs. In such cases\
, a thorough customer
problem analysis must be carried out. Then the same or similar conditions and e\
nvironment in which the
problem occurred in the customer's vehicle should be simulated. No matter how much experience a techni-
cian has, or how skilled he may be, if he proceeds to troubleshoot without c\
onfirming the problem symptoms,
he will tend to overlook something important in the repair operation and make a wrong guess somewhere,
which will only lead to a standstill. For example, for a problem which only o\
ccurs when the engine is cold,
or for a problem which occurs due to vibration caused by the road during d\
riving, etc., the problem can never
be determined when the engine is hot or when the vehicles is at a standsti\
ll. Since vibration, heat or water
penetration (moisture) is a likely cause for the problem which is difficult to reproduce, the symptom simulation
tests introduced here are effective measures in a point that the external causes are applied to the vehicle
in a stationary condition.
Important points in the symptom simulation test:
In the symptom simulation test, the problem symptoms should be confirmed, \
and the problem area or parts
must also be discovered. To do so, reduce the possible problem circuits according to the symptoms before
starting this type of test and have the hand±held tester connected beforehand\
. After that, carry out the symp-
tom simulation test, judging whether the circuit being tested is defective \
or normal and also confirming the
problem symptoms at the same time. Refer to the problem symptoms table of each system to narrow down
the possible causes of the symptom.
1. VIBRATION METHOD: When vibration seems to be
the major cause.
(a) PART AND SENSOR
(1) Apply slight vibration with your finger to the part ofthe sensor considered to be the problem cause and
check whether the malfunction occurs.
HINT:
Applying strong vibration to relays may result in open relays.
(b) CONNECTORS (1) Slightly shake the connector vertically and horizon-tally.
(c) WIRE HARNESS
(1) Slightly shake the wire harness vertically and hori-zontally.
The connector joint and fulcrum of the vibration are
the major areas that should be checked thoroughly.
2. HEAT METHOD: If the problem seems to occur when the area in question is heated.
(a) Heat the component that is the possible cause of the mal- function with a hair dryer or similar object. Check if the
malfunction occurs.
NOTICE:
Do not heat the components to more than 60 C
(140 F) (Temperature is limited to keep the compo-
nents from being damaged).

Do not apply heat directly to the parts in the ECU.
3. WATER SPRINKLING METHOD: When the malfunc- tion seems to occur on a rainy day or in high±humid-
ity.
(a) Sprinkle water onto the vehicle and check if the malfunc- tion occurs.
NOTICE:
Never sprinkle water directly onto the engine
compartment, but indirectly change the temperature
and humidity by spraying a mist of water onto the ra-
diator front surface.
Never apply water directly onto the electronic compo-
nents.
HINT:
If a vehicle is subject to water leakage, the leaking water may
contaminate the ECU. When testing a vehicle with a water leak-
age problem, this factor must also be considered.
4. OTHERS: If the malfunction seems to occur when electrical load is excessive.
(a) Turn on all the electrical equipment including the heater blower, headlights, rear window defogger, etc., and check
if the malfunction occurs.
