Engine System - LPG 159
Service Manual – CS7000
The spark control module is fed power on pin G from the Ignition Request relay. Pin F is connected to
ground.
The two wires form the crank position sensor are connected to pins E and F.
All three ignition coils are fed the same power from the ignition request relay. The 12v power supply flows
through each coil primary circuit to the spark control unit. The spark control unit supplies a “switched
ground” for each of the ignition coil primary windings. When it supplies a ground, current flows through the
coil primary winding and builds up a magnetic field around the coil. When the ground is released, the
current stops flowing abruptly and the magnetic field collapses. The collapsing magnetic field induces a high
voltage in the ignition coil secondary winding which produces a spark across the gap of the spark plug and
ignites the air fuel mixture.
