Circuit / System Description
Ignition voltage is supplied to the ignition coil. The engine control module (ECM) provides a ground for the ignition coil control circuits. When the ECM removes the ground path of the ignition primary coil, the magnetic field produced by the coil collapses. The collapsing magnetic field produces a voltage in the secondary coil which ignites the spark plugs. The sequencing and timing are controlled by the ECM. The ignition coils consist of the following circuits:
