Downloaded from www.Manualslib.com manuals search engine 0A-3 General Information:
There are two kinds of colored wire used in this vehicle. One is single-colored wire and the other is dual-colored
(striped) wire.
The single-colored wire uses only one color symbol (i.e. “GRN”).
The dual-colored wire uses two color sy mbols (i.e. “GRN/YEL”). The first symbo l represents the base color of the wire
(“GRN” in the figure) and the second symbol represents the color of the stripe (“YEL” in the figure).
Fasteners InformationS7RS0B0101004
Metric Fasteners
Most of the fasteners used for this vehicle are JIS-
defined and ISO-defined metric fasteners. When
replacing any fasteners, it is most important that
replacement fasteners be the correct diameter, thread
pitch and strength.
CAUTION!
Even when the nominal diameter (1) of thread
is the same, the thread pitch (2) or the width
across flats (3) may vary between ISO and
JIS. Refer to JIS-TO-ISO Main Fasteners
Comparison Table below for the difference.
Installing a mismatched bolt or nut will cause
damage to the thread.
Before installing, check the thread pitch for
correct matching and then tighten it by hand
temporarily. If it is tight, recheck the thread
pitch.

JIS-TO-ISO Main Fasteners Comparison Table Fastener Strength Identification
Most commonly used metric fastener strength property
classes are 4T, 6.8, 7T, 8.8 and radial line with the class
identification embossed on the head of each bolt. Some
metric nuts will be marked with punch, 6 or 8 mark
strength identification on the nut face. Figure shows the
different strength markings.
When replacing metric fasteners, be careful to use bolts
and nuts of the same strength or greater than the original
fasteners (the same number marking or higher). It is
likewise important to select replacement fasteners of the
correct diameter and thread
pitch. Correct replacement
bolts and nuts are available through the parts division.
Metric bolts: Identification class numbers or marks
correspond to bolt strength (increasing numbers
represent increasing strength).

Downloaded from www.Manualslib.com manuals search engine 1A-2 Engine General Information and Diagnosis:
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• ECM replacement: When substituting a known-good ECM, check for the
following conditions. Neglec ting this check may cause
damage to a known-good ECM.
– Resistance value of all relays, actuators is as specified respectively.
– MAP sensor, A/C refrigerant pressure sensor and TP sensor are in good condition and none of power
circuits of these sensors is shorted to ground.
• Communication of ECM, BCM, ABS/ESP ® control
module, combination meter, keyless start control
module, steering angle sensor (ESP ® model) and
TCM (A/T model), is esta blished by CAN (Controller
Area Network). (For more detail of CAN
communication for ECM, refer to “CAN
Communication System Description”). Therefore,
handle CAN communication line with care referring to
“Precaution for CAN Communication System in
Section 00”.
• Immobilizer transponder code registration after
replacing ECM
When ECM is replaced with new one or with another
one, make sure to register immobilizer transponder
code to ECM correctly according to “Procedure after
ECM Replacement in Section 10C”.Precautions of ECM Circuit InspectionS7RS0B1100003
• ECM connectors are waterproofed. Each terminal of the ECM connectors is sealed up with the grommet.
Therefore, when measuring ci rcuit voltage, resistance
and/or pulse signal at ECM connector, do not insert
the tester’s probe into th e sealed terminal at the
harness side. When measuring circuit voltage,
resistance and/or pulse signal at ECM connector,
connect the special tool to the ECM connectors. And,
insert the tester’s probe into the special tool’s
connectors at the harness side, and then measure
voltage, resistance and/or pulse signal. Or, ECM and
its circuits may be damaged by water.
• Wire colors of the special tool’s connectors are different from the ones of the ECM connectors.
However, the circuit arrangement of the special tool’s
connectors is same as the one of the ECM
connectors. Therefore, measure circuit voltage and
resistance by identifying the terminal location subject
to the measurement.
Precautions of Electric Throttle Body System
Calibration
S7RS0B1100004
After performing one of works described below, it is
necessary to re-register the completely closed throttle
valve reference position stored in memory of ECM. (For
detailed information, refer to “Description of Electric
Throttle Body System Calibration”.) For the procedure to
register such data in ECM, refer to “Electric Throttle
Body System Calibration in Section 1C”.
• To shut off backup power of ECM for such purposes of battery replacement or “DOME” fuse removal
• To erase DTCs P0122, P01 23, P0222, P0223, P2101,
P2102, P2103, P2111, P2112, P2113, P2119, P2123,
P2127, P2128, P2135 and/or P2138
• To replace ECM
• To replace throttle body and/or accelerator pedal position (APP) sensor assembly
General Description
Statement on Cleanliness and CareS7RS0B1101001
An automobile engine is a combination of many
machined, honed, polished and lapped surfaces with
tolerances that are measured in the thousands of an
millimeter (ten thous ands of an inch).
Accordingly, when any internal engine parts are
serviced, care and cleanliness are important.
It should be understood that proper cleaning and
protection of machined surfaces and friction areas is part
of the repair procedure. This is considered standard
shop practice even if not specifically stated.
• A liberal coating of engine oil should be applied to friction areas during assembly to protect and lubricate
the surfaces on initial operation. • Whenever valve train components, pistons, piston
rings, connecting rods, rod bearings, and crankshaft
journal bearings are removed for service, they should
be retained in order.
At the time of installation, they should be installed in
the same locations and with the same mating
surfaces as when removed.
• Battery cables should be disconnected before any major work is performed on the engine.
Failure to disconnect cables may result in damage to
wire harness or other electrical parts.
