How does the ignition control module work on a car?
In a nutshell, when the system is working properly, at crank-up and below 400 RPM’s the ignition control module controls spark (by activating the three ignition coils that sit on top of it) without help from the fuel injection computer. When you turn the Key to start the engine, the ignition control module gets power (12 Volts) and Ground.

Which is CKP signal does the GM 3.8L ignition module use?
One CKP sensor is called the 3X CKP Sensor and the signal it creates is called the Sync 3X CKP Signal and the other one is called the 18X CKP and its signal the Crank 18X CKP Signal. As stated before, both of these signals are critical for the ignition control module to start the car (to start sparking the ignition coils).
Is the ignition switch part of the PCM?
The ignition switch now talks to the body control module (BCM) and it’s the BCM that initiates one of two relays. The second relay, the more important of the two, is controlled by the powertrain control module (PCM).
