• 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.

following steps.
1) For APP sensor (main) , arrange 3 new 1.5 V 
batteries (1) in series (check that total voltage is 4.5 - 
5.0 V) and connect its positive terminal to “Vin 1” 
terminal (2) and negative terminal to “Ground 1” 
terminal (3) of sensor. Then using voltmeter, connect 
positive terminal to “Vout 1” terminal (4) of sensor 
and negative terminal to battery.
2) For APP sensor (s ub), arrange 3 new 1.5 V batteries 
(1) in series (check that total voltage is 4.5 - 5.0 V) 
and connect its positive terminal to “Vin 2” terminal 
(2) and negative terminal to “Ground 2” terminal (3) 
of sensor. Then using volt meter, connect positive 
terminal to “Vout 2” terminal (4) of sensor and 
negative termin al to battery.
3) Measure output voltage variation while accelerator  pedal is no depressed and fully depressed as 
following specification.
If sensor voltage is out of  specified value or does not 
vary linearly as the followin g graph, replace APP sensor 
assembly.
APP sensor output voltage
APP sensor (main) output voltage [A]: 0.75 – 3.85 V, 
varying according to depressed extent of
