jectors during this test, don't crank the engine for more
than 5 ~ 10 seconds at a time.
OK:

DTC P1300 Igniter Circuit Malfunction
CIRCUIT DESCRIPTION
A DIS (Direct Ignition System) has been adopted. The DIS improves the ignition timing accuracy, reduces
high±voltage loss, and enhances the overall reliability of the ignition system by eliminating the distributor.
The DIS is a 2±cylinder simultaneous ignition system which ignites 2 cylinders simultaneously with one igni-
tion coil. In the 2±cylinder simultaneous ignition system, each of the 2 spark plugs is connected to the end
of the secondary winding. High voltage generated in the secondary winding is applied directly to the spark
plugs. The sparks of the 2 spark plugs pass simultaneously from the center electrode to the ground elec-
trode.
The ECM determines ignition timing and outputs the ignition signals (IGT) for each cylinder. Based on IGT
signals, the igniter controls the primary ignition signals (IGC) for all ignition coils. At the same time, the igniter
also sends an ignition confirmation signal (IGF) as a fail±safe measure to the ECM.

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT IGNITION COIL CONNECTORS
3. REMOVE SPARK PLUGS (See page IG±1)
4. INSPECT CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible.
Compression pressure:
1,226 kPa (12.5 kgf/cm
2, 178 psi) or more
Minimum pressure: 981 kPa (10.0 kgf/cm
2, 142 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
(e) If the cylinder compression in one or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (c) for
cylinders with low compression.

If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.

If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG±1)

HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. REMOVE IGNITION COILS AND HIGH±TENSION
CORDS (See page IG±7)
3. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the 6 spark plugs.
4. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible.
Compression pressure:
1,500 kPa (15.3 kgf/cm
2, 218 psi)
Minimum pressure: 1,000 kPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 15 psi) or less
(e) If the cylinder compression in 1 or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (c) for
cylinders with low compression.

If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.

If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
