An ignition module, also referred to as an ignition management module (ICM), is an digital machine that controls the timing and length of the spark in an inner combustion engine. A correctly functioning ignition module is crucial for guaranteeing that the engine begins and runs easily.
There are a couple of alternative ways to verify an ignition module. One methodology is to make use of a multimeter to measure the resistance of the module. One other methodology is to make use of an oscilloscope to watch the waveform of the spark. If the resistance or waveform is exterior of the producer’s specs, the ignition module might have to be changed.
