Circuit Description
The Electronic Ignition (EI) system uses a waste spark method of spark distribution. The Crankshaft Position (CKP)
sensor sends reference pulses to the ECM. The ECM then triggers the EI system ignition coils. Once the ECM triggers
the EI system ignition coils both of the connected spark plugs fire at the same time. One cylinder is on its compression
stroke at the same time that the other is on the exhaust stroke, resulting in lower energy needed to fire the spark plug in
the cylinder on its exhaust stroke.
This leaves the remainder of the high voltage to be used to fire the spark plug in the cylinder on its compression stroke.
Since the CKP sensor is in a fixed position, timing adjustments are not possible or needed.

Leakage Test
1. Warm the engine up to normal operating tempera-
ture.
2. Disconnect the negative battery cable.
3. Remove the spark plugs.
4. Check the coolant level by opening the coolant
surge tank cap and replenish if insufficient.
5. Open the engine oil filler cap.
6. Connect the tester to air pressure line and adjust the
scale of tester.
7. Install the connecting hose to spark plug hole.
YAA1A2080
8. Position the piston of No.1 cylinder at TDC by rotat-
ing the crankshaft.
9. Connect the connecting hose to tester and measure
the leakage volume after blowing up compressed
air.
Notice:Measure the leakage volume in the completely
opening condition of throttle valve by pulling the accel-
eration cable.
10. Perform the pressure test according to the firing or-
der.
Notice:Firing Order : 1 -- 3 -- 4 -- 2
11. Compare the leakage pressure with the specifica-
tions.

Measuring Procedure
1. Warm the engine up to normal operating tempera-
ture.
2. Remove the spark plugs.
3. Place the diagram sheet to compression pressure
tester.
4. Connect the adaptor to compression pressure tester
and install it into the spark plug hole.
5. Crank the engine approx. eight revolutions by using
the start motor.6. Compare the measurements of compression pres-
sure tester with the specifications.
7. Measure the compression pressure of the other cylin-
ders in the same way.
8. If measured value is not within the specifications, per-
form the cylinder pressure leakage test.
Notice
DDischarge the combustion residues in the cylinders
before testing the compression pressure.
DApply the parking brake before cranking the engine.

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
YAA1F920
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 1 and 4
T1/2: cylinder 2 and 3
The EI system ignition coil is not serviceable and must be replaced as an assembly.
