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.

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.

(i)TORQUE WHEN USING TORQUE WRENCH WITH EX-
TENSION TOOL
(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
torque value, the actual torque becomes excessive.
(2)In this manual, only the specified torque is de-
scribed. In case of using SST or extension tool, cal-
culate the reading of the torque wrench by the fol-
lowing formula.

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.
