CIRCUIT DESCRIPTION
HINT:

These DTCs indicate a malfunction related to primary circuit.

If DTC P0351/14 is displayed, check No.1 ignition coil with igniter circuit.

If DTC P0352/15 is displayed, check No.2 ignition coil with igniter circuit.

If DTC P0353/14 is displayed, check No.3 ignition coil with igniter circuit.

If DTC P0354/15 is displayed, check No.4 ignition coil with igniter circuit.
A Direct Ignition System (DIS) 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 1±cylinder ignition system which ignites one cylinder with one ignition coil. In the 1±cylinder
ignition system, the one spark plug is connected to the end of the secondary winding. High voltage generated
in the secondary winding is applied directly to the spark plug. The spark of the spark plug passes from the
center electrode to the ground electrode.
The ECM determines the ignition timing and outputs the ignition (IGT) signals for each cylinder. Based on
the IGT signals, the power transistors in the igniter cut off the current to the primary coil in the ignition coil
is supplied to the spark plug that is connected to the end of the secondary coil. At the same time, the igniter
also sends an ignition confirmation (IGF) signal as a fail±safe measure to the ECM.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lean or rich, etc. at the time of the mal-
function.

BASIC INSPECTION
When the malfunction code is not confirmed in the DTC check, troubleshooting should be carried out in all
the possible circuits considered as causes of the problems. In many cases, by carrying out the basic engi\
ne
check shown in the following flow chart, the location causing the problem can be found quickly and efficiently.
Therefore, using this check is essential in the engine troubleshooting.
