open position, check thatthe throttle valve opening percentage (THROTTLE POS) of the CURRENT DATA shown the
standard value.

If operation is not as specified, check that the accelerator pedal positio\
n sensor (See page 10±39), wiring
and ECM.
If you have no hand±held tester, measure voltage between terminals (VTA1 ± E2, VTA2 ± E2) of the ECM
connector (See page 05±318).
(c) Inspect the air assist system.
(1) Start the engine and check that the CHK ENG does not light up.
(2) Allow the engine to warm up to normal operating temperature.
(3) Turn the A/C compressor ON to OFF, and check the idle speed.
Idle speed (Transmission in neutral): 700 50 rpm
NOTICE:
Perform inspection under condition without electrical load.
(d) After checking the above (b) to (d), perform the driving test and check that there is no sense of incon-
gruity.
4. INSPECT ACCELERATOR PEDAL POSITION SENSOR
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Check that the voltage (ACCEL POS) of the CURRENT DATA shown the standard value.

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.

± INTRODUCTIONREPAIR INSTRUCTION
AVENSIS REPAIR MANUAL (RM1018E)
(±) 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.
