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.

HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
GENERAL INFORMATION
There are many ECU controlled systems used in the AVENSIS. In general, ECU controlled system are con-
sidered to be very intricate and require a high level of technical knowledge an\
d expert skill to troubleshoot.
The fact is, however, that if you proceed by inspecting the circuits one by one, troubleshoo\
ting of these sys-
tems is not complex. If you have adequate understanding of the system and ba\
sic knowledge of electricity,
the problem can be accurately diagnosed and fixed. This manual is design\
ed based on the above principle
to help service technicians perform accurate and effective troubleshooting, and is compiled for the following
major ECU controlled systems:
The troubleshooting procedures are described on the following pages.

22.Multiplex Communication System05±1654
23.Cruise Control System05±1697
FOR USING HAND±HELD TESTER
Before using the tester, the tester's operator manual should be read thoroughly.
If the tester cannot communicate with the ECU controlled systems when you \
have connected the cable
of tester to the DLC3, turned the ignition switch ON and operated the test\
er, there is a problem on the
vehicle side or tester side.
(1) If the communication is normal when the tester is connected to another veh\
icle, inspect the diag-
nosis data link line (Bus line) or ECU power circuit of the vehicle.
(2) If the communication is still impossible when the tester is connected to a\
nother vehicle, the prob- lem is probably in the tester itself, so perform the Self Test procedures outlined in the Tester Oper-
ator 's Manual.

SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE
HINT:
The diagnostic system in AVENSIS has various functions. The first function is the Diagnostic Trouble
Code (DTC) Check, in which a malfunction in the signal circuits to the ECU is stored in code form in
the ECU memory. Another function is the Input Signal Check, which checks if the signals from various
switches are sent to the ECU correctly. By using these check functions, it is possible to quickly narrow
down potential problem areas and troubleshooting can be performed effectively. The diagnostic func-
tions are incorporated in the following systems in the AVENSIS.

Cruise Control System
In the DTC check, it is very important to determine whether the problem indicated by the DTC is still
occurring or has occurred in the past but returned to normal at present. In addit\
ion during the problem
symptom check, it a check must be made on whether the malfunction indicated by \
the DTC is directly
related to the problem symptom or not. For this reason, the DTC should be checked before and after
symptom confirmation to determine the current conditions. If this is not done, \
it may, depending on the
case, result in unnecessary troubleshooting for systems that are operati\
ng normally. This would make
more difficult to detect the problem area or to try to repair irrelevant areas. \
Therefore, always follow
the procedures in the correct order and perform the DTC check.
A flow chart showing how to proceed with troubleshooting using the diagnostic trouble\
code (DTC)
check is shown the this page. This flow chart shows how to utilize the DTC check effectively. Then,
by carefully checking the results, this chart indicates how to proceed either to the DTC troubleshooting
or to the troubleshooting of the problem symptoms table.

(b) JACKING UP AND SUPPORTING VEHICLE (1) Care must be taken when jacking up and supporting the vehicle. Be sure to li\
ft and support thevehicle at the proper locations (See page 01±19).
(c) PRECOATED PARTS(1) Precoated parts such as bolts, nuts, etc., are
coated with a seal lock adhesive at the factory.
(2) If a precoated part is retightened, loosened or caused to move in any way, it must be recoated with
the specified adhesive.
(3) When reusing precoated parts, clean off the old
adhesive and dry the part with compressed air.
Then apply the specified seal lock adhesive to the
bolt, nut or threads.
NOTICE:
Check the torque with the lower limit value of the torque tol-
erance.
(4) Depending on the seal lock agent to be applied,there may be cases where it is necessary to leave
it for a specified time until it hardens.
(d) GASKETS (1) When necessary, use a sealer on gaskets to prevent leaks.
(e) BOLTS, NUTS AND SCREWS (1) Carefully follow all the specifications for tightening torques. Always u\
se a torque wrench.
(f) FUSES(1) When replacing fuses, be sure that a new fuse hasthe correct amperage rating. DO NOT exceed the
rating, or use one with a lower rating.

(1)When the torque wrench is combined with SST oran extension tool to extend the length, and you
tighten until the torque wrench reads the specified

2.FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER
HINT:
The AVENSIS is equipped with an SRS (Supplemental Restraint System), which \
includes the driver airbag,
front passenger airbag and seat belt pretensioner.
Failure to carry out the service operations in the correct sequence could cause\
the supplemental restraint
system to unexpectedly deploy while servicing. This could cause a seriou\
s accident.
Furthermore, if a mistake is made when servicing the supplemental restra\
int system, it is possible that the
SRS will fail to operate when required. Before servicing (including remova\
l or installation of parts, inspection
or replacement), be sure to read the following items carefully. Then follow the correct procedures described
in this manual.
(a)GENERAL NOTICE (1)Malfunction symptoms of the supplemental restraint system are difficult to confirm so the diag-nostic trouble codes become the most important source of information when trou\
bleshooting.
When troubleshooting the supplemental restraint system, always check the dia\
gnostic trouble
codes before disconnecting the battery (See page 05±1184).
(2) Work must be started after 90 seconds from the time that the ignition switch\
is turned to the LOCK position and the negative (±) terminal cable is disconnected from the batte\
ry.
(The supplemental restraint system is equipped with a back±up power sourc\
e. So, if work is
started within 90 seconds after disconnecting the negative (±) terminal ca\
ble from the battery,
the SRS may deploy).
When the negative (±) terminal cable is disconnected from the battery, memory of the clock and
audio systems is cancelled. So, before starting work, make a record of the contents recorded
in each memory system. Then, when work is finished, reset the clock and audio systems as be-
fore.
