(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.

(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

VARIABLE RESISTOR CIRCUIT
CIRCUIT DESCRIPTION
The variable resister has been adopted to leaded±type vehicle only.
This resistor is used change the air±fuel ratio of the air±fuel mixture.
The idle mixture is adjusted using this resistor.
Turning the idle mixture adjusting screw clockwise moves the contacts inside the resistor, raising the terminal
VAF voltage. Conversely, turning the screw counterclockwise lowers the terminal VAF voltage.
When the terminal VAF voltage rises, the ECM increases the injection volume slightly, marking the air±fuel
mixture a little richer.

INSPECTION PROCEDURE
NOTICE:
Always use a CO meter when adjusting the idle mixture. If a CO meter is not available, DO NOT AT-
TEMPT TO ADJUST IDLE MIXTURE.
