DTC P0354 Ignition Coil 'D' Primary/Secondary Circuit Malfunction

DESCRIPTION
Ignition coil is used as the energy storage device and also functions as a transformer, boosting the secondary ignition voltage. Electrical energy is supplied to the coil's primary circuit. Before the ignition point, the coil is charged during the dwell period. At the ignition point, the primary current will be controlled by the ECM. The rapid change of the magnetic field induces the secondary voltage in the secondary circuit. A distribution system assigns the high voltage to the corresponding spark plug. After exceeding the arching over voltage at the spark plug, the coil will be discharged during the spark duration.The spark plugs are paired so that as one spark plug fires on the compression stroke, the other spark plug fires on the exhaust stroke. The pair of spark plugs tire in the engine firing order.
