Hint
:
A direct ignition system (dis) is used on this vehicle. 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 signals (igt) for each cylinder. Using the ignition (igt) signal, the ecm turns on and off the power transistor inside the igniter and this switches on and off the current to the primary coil. When the current flow to the primary coil is cut off, high–voltage is generated in the secondary coil and this voltage is applied to the spark plugs to spark inside the cylinders.
As the ecm cuts the current to the primary coil, the igniter sends back the ignition confirmation (igf) signal for each cylinder ignition to the ecm.
Monitor description
If the ecm does not receive the ignition confirmation signal (igf) after sending the ignition signal (igt), it interprets this as a fault in the igniter and sets a dtc.
