ENGINE CONTROL MODULE
YAA1F830
The Engine Control Module (ECM), located inside the right side kick panel, is the control center of the fuel injection
system. It constantly looks at the information from various sensors and controls the systems that affect the vehicle’s
performance. Engine rpm and air mass are used to measure the air intake quantity resulting in fuel injection metering.
The ECM also performs the diagnostic functions of the system. It can recognize operational problems, store failure
code(s) which identify the problem areas to aid the technician in making repairs.
There are no serviceable parts in the ECM. The calibrations are stored in the ECM in the Programmable Read Only
Memory (PROM).
The ECM supplies either 5 or 12 volts to power the sensors or switches. This is done through resistance in the ECM
which are so high in value that a test light will not come ON when connected to the circuit. In some cases, even an
ordinary shop voltmeter will not give and accurate reading because its resistance is too low. You must use a digital
voltmeter with a 10 Mohm input impedance to get accurate voltage readings. The ECM controls output circuits such as
the ignition coils, the fuel injectors, the fuel pump relay, the camshaft actuator, the canister purge valve, etc., by con-
trolling the ground circuit.

Circuit Description
Immobilizer is a device disabling vehicle ignition unless a specific key is used and designed to help prevent vehicle
theft.
Immobilizer is comprised of two devices, a key with encoded transponder and ECM with the same encoding of the
transponder. When a key is inserted into the hole to start vehicle and turned to ON, the ECM reads and decodes the
transponder code and, if the same, starts the engine, it is called immobilizer. It means immobilizersystem disables
starting by stopping fuel supply if the code in the transponder does not match the code stored in ECM each other.

Caution: The fuel system is under pressure. To
avoid fuel spillage and the risk of personal injury or
fire, it is necessary to relieve the fuel system pres -
sure before disconnecting the fuel lines.
3. Relieve the fuel pressure in fuel supply system by
pressing the service valve.

4. Disconnect the vacuum hose.
5. Disconnect the circlip and remove the fuel pressure
regulator.
6. Apply the oil to O-ring lightly and then replace it.
7. Perform a leak test of the fuel pressure regulator
with the engine off and the ignition on.
8. Installation should follow the removal procedure in
the reverse order.

GENERAL INFORMATION
CLEANLINESS AND CARE
An automobile engine is a combination of many ma-
chined, honed, polished and lapped surfaces with toler-
ances that are measured in the ten-- thousanths of an
inch. When any internal engine parts are serviced, care
and cleanliness are important. A liberal coating of en-
igne oil should be applied to friction areas during assem-
bly, to protect and lubricate the surfaces on initial
operation. Proper cleaning and protection of machined
surfaces and friction areas is part fo the repair proce-
dure. This is considered standard shop practice even if
not specifically stated.
Whenever valve train components are removed for ser-
vice, they should be kept in order. They should be
installed in the same locations, and with the same mat-
ing surfaces, as when they were removed.
Battery cables should be disconnected before any major
work is performed on the engine. Failure to disconnectcables may result in damage to wire harness or other
electrical parts.
ON-- ENGINE SERVICE
Caution: Disconnect the negative battery cable be -
fore removing or installing any electrical unit, or
when a tool or equipment could easily come in con-
tact with exposed electrical terminals. Disconnect -
ing this cable will help prevent personal injury and
damage to the vehicle. The ignition must also be in
LOCK unless otherwise noted.
Notice:Any time the air cleaner is removed, the intake
opening should be covered. Thiswill protect against ac-
cidental entrance of foreign material, which could follow
the intake passage into the cylinder and cause exten-
sive damage when the engine is started.
