Precaution for Vehicle Equipped with ESP®
System
S7RS0B0000015
• When testing with any of the following equipments
(when vehicle is tested by rotating wheels (tires)
under vehicle stop), be sure to deactivate ESP ®
system referring to “Precautions in Speedometer Test
or Other Tests in Section 4F” to obtain correct data.
– 2 or 4-wheel chassis dynamometer
– Speedometer tester
– Brake tester
–Etc.
ESP ® control module
• When ESP ® control module is removed / installed, do
not use impact wrenches which generate shock or
impact to avoid damaging sensors in ESP ® control
module.
• When any of the following operation is done, calibrate steering angle sensor referring to “Sensor Calibration
in Section 4F”.
– When battery or dome fuse is removed.
– When steering angle sensor is replaced.
Brake CautionS7RS0B0000014
CAUTION!
All brake fasteners are important attaching
parts in that they could affect the
performance of vital parts and systems, and/
or could result in major repair expense. They
must be replaced with one of same part
number or with an eq uivalent part if
replacement becomes necessary. Do not use
a replacement part of lesser quality or
substitute design. Torque values must be
used as specified during reassembly to
assure proper retention of all parts. There is
to be no welding as it may result in extensive
damage and weakening of the metal.

Electrical Circuit Inspection ProcedureS7RS0B0006001
While there are various electrical circuit inspection
methods, described here is a general method to check
its open and short circuit by using an ohmmeter and a
voltmeter.
Open Circuit Check
Possible causes for the open circuit are as follows. As
the cause is in the connector or terminal in many cases,
they need to be checked particularly carefully.
• Loose connection of connector
• Poor contact of terminal (due to dirt, corrosion or rust
on it, poor contact tension, entry of foreign object etc.)
• Wire harness being open
When checking system circuits including an electronic
control unit such as ECM, TCM, ABS control module,
etc., it is important to perfor m careful check, starting with
items which are easier to check.
1) Disconnect negative (–) cable from battery
2) Check each connector at both ends of the circuit being checked for loose connection. Also check lock
condition of connector if equipped with connector
lock. 3) Using a test male terminal
, check both terminals of
the circuit being checked for contact tension of its
female terminal. Check each terminal visually for
poor contact (possibly caused by dirt, corrosion, rust
entry of foreign object, etc.). At the same time, check
to make sure that each te rminal is locked in the
connector fully.
1. Check contact tension by inserting and removing just for once.

• 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.

Description of Electric Throttle Body System CalibrationS7RS0B1101008
ECM calculates controlled opening of the throttle valve on the basis of the completely closed throttle valve position of
the electric throttle body system. The completely closed position data is saved in memory of ECM. However, the
completely closed position of the throttle valve of the electric throttle body system (signal voltage from throttle position
sensor when throttle is completely closed) differs one from the other depending on individual differences of the throttle
valve and throttle position sensor. As such individual diff erences must be taken into account for controlling the throttle
valve, it is necessary to register the completely closed throttle valve position data in ECM. When such data is
registered in ECM, it is sa ved in RAM (memory) of ECM and used as the base data for controlling the throttle valve.
This data is cleared, when any of the works described in “Preca utions of Electric Throttle Body System Calibration” is
performed.
Also, after replacement of the throttle body and/or APP sensor , the completely closed position data in memory of ECM
must be cleared once and a new one must be registered, or ECM cannot judge the complete closure position properly.
For the procedure to register such data, refer to “Electric Throttle Body System Calibration in Section 1C”. (After the
completely closed position data is cleared , ECM, for the first time only, opens and closes the throttle valve for about 5
seconds after the ignition switch is turned ON position, for re gistration of the completely closed throttle valve position.
If the engine is started during this registration process, such symptom as “longe r cranking” or “slow rise of revolution
speed immediately after start-up” may occur. However, turning OFF the ignition switch once and restarting will set
correct registration.)
