What does the PCM do for the ignition coil?

What does the PCM do for the ignition coil?

With these two signals, the PCM activates the Auto Shutdown (ASD) Relay to feed power to pretty much every electronic component under the hood, especially the ignition coil. Without these two signals, the PCM will not activate the ASD Relay.

How does the crank sensor work in an ignition system?

It does this by switching the Primary Current, flowing across the ignition coil, on and off. This on/off action will henceforth be called the Switching Signal. The crank sensor is at the heart of this type Ignition System. Here are some useful facts that you should be aware of about the crank sensor on your Chrysler (or Dodge or Plymouth) vehicle:

What does the switch on the ignition coil do?

Also, with the signals from the crankshaft (and Camshaft) Position Sensor Assembly, the PCM starts to activate the ignition coil to start sparking away. It does this by switching the Primary Current, flowing across the ignition coil, on and off. This on/off action will henceforth be called the Switching Signal.
