- If DTC P0356 is set, check the No. 6 ignition coil assembly circuit.
A direct ignition system is used on this vehicle.
The direct ignition system is a 1-cylinder ignition system in which each cylinder is ignited by one ignition coil assembly and a spark plug is
connected to the end of each secondary wiring. A powerful voltage, generated in the secondary wiring, is applied directly to each spark plug. Spark
of the spark plugs passes from the center electrode to the ground electrodes.
The ECM determines the ignition timing and transmits the ignition signals (IGT) to each cylinder. Using the IGT signal, the ECM turns the power
transistor inside the igniter on and off. The power transistor, in turn, switches on and off the current to the primary coil. When the current to the
primary coil is cut off, a powerful voltage is generated in the secondary coil. This voltage is applied to the spark plugs, causing them to spark inside
the cylinders. As the ECM cuts the current to the primary coil, the igniter sends back an ignition confirmation signal (IGF) to the ECM, for each
