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.
 
Repair Instructions
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.

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.

CAN communication system uses the serial communication in which data is transmitted at a high speed. It uses a 
twisted pair of two communication lines for the high-speed da ta transmission. As one of its characteristics, multiple 
control modules can communicate simultaneously. In addition, it has a function to detect a communication error 
automatically. Each module reads necessary data from the received data and transmits data. ECM communicates 
control data with each control module as follows.
ECM Transmission Data
NOTE
• In communication between ECM and combination meter and between ECM and steering angle  sensor (ESP ® model), data is transmitted only from ECM to combination meter and steering angle 
sensor. (Combination meter and steering angle sensor does not transmit data to ECM.)
