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 20C (68F). As the re-
sistance may be outside the specifications if measured at high temperatures immediately after
the vehicle has been running, measurements should be made when the engine has 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.

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 environment 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 confirming 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 occurs when the engine is cold,
or for a problem which occurs due to vibration caused by the road during driving, etc., the problem can never
be determined when the engine is hot or when the vehicles is at a standstill. 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 of
the 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 60C
(140F) (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.

(3)Grease should not be attached to the curtain shield airbag assembly, and the surface should not be cleared with detergents of any kind.
(4)Store the airbag assembly where the ambient temperature remains below 93
C (200
F), without
high humidity and away from electrical noise.
(5)When using electric welding, first disconnect the airbag connector (4 yellow pins) from th\
e instru- ment panel before starting work.
(6)When disposing of a vehicle or the curtain shield airbag assembly alone, the airbag should be
deployed using SST before the disposal (See page 60±41). Perform operation in a safe place
away from electrical noise.
(h)SEAT BELT PRETENSIONER (1)Never measure the resistance of the seat belt pretensioner (This may cause t\
he seat belt preten-sioner to activate, which is very dangerous.).
(2)Never disassemble the seat belt pretensioner.
(3)Never install the seat belt pretensioner in another vehicle.
(4)Store the seat belt pretensioner where the ambient temperature remains b\
elow 80
C (176
F)
without high humidity and away from electrical noise.
(5)When using electric welding, first disconnect the connector (2 yellow pins) before starting work.
(6)When disposing of a vehicle or the seat belt pretensioner alone, the seat belt pretensi\
oner should
be activated before disposal (See page 61±9). Perform the operation in a safe place away from
electrical noise.
(7) The seat belt pretensioner is hot after being activation, so allow some \
time for it to cool down sufficiently before disposal. Never apply water to cool down the seat be\
lt pretensioner.

(8) Oil or water should not be put on the front seat outer belt and the front seat outer belt should be
cleaned with the appropriate detergents.
(i) AIRBAG SENSOR ASSEMBLY
(1) Never reuse the airbag sensor assembly involved in a collision where the SRS has deployed.
(2) The connectors to the airbag sensor assembly should be connected or disconnected with the
sensor mounted on the floor. If the connectors are connected or disconnected while the airbag
sensor assembly is not mounted to the floor, it could cause an undesired ignition of the supple-
mental restraint system.
(3) Work must be started after 90 seconds from the time the ignition switch is turned to the ºLOCKº
position and the negative (±) terminal cable is disconnected from the battery, even if only loosen-
ing the set bolts of the airbag sensor assembly.
(j) WIRE HARNESS AND CONNECTOR
(1) The SRS wire harness is integrated with the instrument panel wire harness assembly. All connec-
tors in the system are a standard yellow color. If the SRS wire harness becomes disconnected
or the connector becomes broken due to an accident, etc., repair or replace it.
3. ELECTRONIC CONTROL
(a) REMOVAL AND INSTALLATION OF BATTERY TERMI-
NAL
(1) Before performing electronic work, disconnect the
battery negative (±) terminal cable beforehand in
order to prevent it from shorting and burning out.
(2) When disconnecting and installing the terminal
cable, turn the ignition switch and lighting switch
OFF, and loosen the terminal nut completely. Per-
form these operations without twisting or prying the
terminal.
(3) When the battery terminal cable is removed, the
memories of the clock, radio, DTCs, etc. are erased.
So before removing it, check them and make a note
of their settings.
(4) When the battery negative (±) terminal cable is dis-
connected, memories of various systems are
erased. Therefore, refer to the PRE±CHECK for
each system to make sure whether or not the sys-
tem needs to be initialized after the battery negative

(±) terminal cable is disconnected. If necessary, be
sure to initialize the system.
(b) HANDLING OF ELECTRONIC PARTS
(1) Do not open the cover or case of the ECU unless
absolutely necessary (If the IC terminals are
touched, the IC may be rendered inoperative by
static electricity).
(2) To disconnect electronic connectors, pull the con-
nector itself, not the wires.
(3) Be careful not to drop electronic components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not be reused.
(4) When cleaning the engine with steam, protect the
electronic components, air filter and emission±re-
lated components from water.
(5) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(6) When checking the continuity at the wire connector,
insert the tester probe carefully to prevent terminals
from bending.
4. REMOVAL AND INSTALLATION OF FUEL CONTROL PARTS
(a) PLACE FOR REMOVING AND INSTALLING OF FUEL SYSTEM PARTS
(1) Work in a place with good air ventilation and without anything that could cause combustion
around you such as a welder, grinder, drill, electric motor or stove.
(2) Never work in a place such as a pit or nearby a pit, as there is a possibility that vaporized fuel
will collect in those places.
(b) REMOVING AND INSTALLING OF FUEL SYSTEM PARTS
(1) Prepare a fire extinguisher before starting operations.
(2) To prevent static electricity, install a ground on the fuel changer, vehicle and fuel tank, and do
not spray much water so as to prevent slipping.
(3) Never use any electric equipment like an electric motor or a working light, as they may create
sparks or a high temperature.
(4) Never use an iron hammer, as it may create sparks.
(5) Dispose of shop rags containing fuel deposits separately.
5. REMOVAL AND INSTALLATION OF ENGINE INTAKE
PARTS
(a) If any metal tip is mixed in the inlet pass, this may give a
bad effect to the engine and turbocharger.
(b) When removing and installing the inlet system parts,
close the opening of the removed inlet system parts and
the engine with a clean waste cloth or gum tape.
(c) When installing the inlet system parts, check that there is
no mixing of a metal tip.
