CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless other -
wise noted.

IGNITION COIL
YAA1F240
The Electronic Ignition (EI) system ignition coil is located on the cylinder head cover. The double ended coils receive
the signal for the Engine Control Module (ECM) which controls the spark advance.
Each EI system ignition coil provides the high voltage to two spark plugs simultaneously;
T1/1: cylinder 2 and 5
T1/2: cylinder 3 and 4
T1/3: cylinder 1 and 6
The EI system ignition coil is not serviceable and must be replaced as an assembly.

Measure the Fuel Delivery from the Fuel Pump
1. Disconnect the return pipe from fuel distributor and insert the appropriate hose into it.
2. Place the hose end into the beaker with the minimum capacity of 1 Liter
3. Turn the ignition switch to “ON” position.
4. Connect the terminal No. 33 and No. 5 of ECM with a service wire.
5. Measure the fuel delivery from the fuel pump
Specified Value
1 Liter/max. 35 sec.
Notice:Check the fuel filter and fuel line when the fuel delivery is not within specified value.
Measure the Current Consumption of Fuel Pump
1. Remove the fuel pump relay from fuse and relay box in trunk, and turn the ignition switch to “ON” position.
2. Using a multimeter, measure the current consumption by connecting the terminal No. 30 and No. 87 of the fuel
pump relay connector.
Specified Value
5~9A
Notice:Replace the fuel pump relay if the measured value is over 9 A.

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 intake manifold resonance flap, the camshaft actuator, the
canister purge valve, etc., by controlling the ground circuit.

ing the Pressure in Fuel System” in this section.
2. Disconnect the negative battery cable.
3. Put aside the floor carpet to remove the fuel pump ac-
cess cover.
4. Remove the fuel pump access cover.
5. Remove the fuel pump wiring connectors.
6. Disconnect the fuel supply and return pipes.
7. Remove the fuel pump locking cap band.

Notice:Before removal, the fuel rail assembly may be
cleaned with a spray-type cleaner, following package in-
structions. Do not immerse the fuel rails in liquid clean-
ing solvent. Use care in removing the fuel rail assembly
to prevent damage to the electrical connectors and in-
jector spray tips. Prevent dirt and other contaminants
from entering open lines and passages. Fittings should
be capped and holes plugged during service.
Important:If an injector becomes separated from the
rail and remains in the cylinder head, replace the injector
O-ring seals and the retaining clip.
12. Remove the injectors and the fuel rail carefully.
13. Remove the fuel injector retainer clips.
14. Remove the fuel injectors by pulling them down and
out.
15. Discard the fuel injector O-rings.
16. Lubricate the new fuel injector O-rings with engine
oil. Install the new O-rings on the fuel injectors.
17. Perform a leak check of the fuel rail and fuel injec-
tors.
