± 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.
