How does the ICM activate the ignition coil?
How does the ICM activate the ignition coil?
The ICM activates the ignition coil to start sparking by turning on and off (interrupting) the Ground circuit. You and I can check the ignition coil by checking that it’s getting power and that the ICM is supplying the ignition coil’s activation signal.
How does the ignition coil on a Chevy S10 work?
Fuel pump is working. How Does The Ignition Coil Work? Even though the ignition coil on the 2.8 v6 Chevy S10 has four wires coming out of its connector, it’s a component that works on 12 Volts and ground. In this section I am going to break down how the ignition coil creates a spark in plain English (and in a step-by-step manner).
How does the Pick Up Coil work on an engine?
As the engine starts to crank, the pick-up coil (which is the defacto crankshaft position sensor) starts to generate its position signals to the ignition control module.
Where does the pick up coil signal go in an ignition module?
This pick up coil signal is sent directly to the ignition control module. The ignition module, upon receiving this pick up coil signal (for all intended purposes it’s a crankshaft position sensor signal) converts it to a digital signal that is now sent to the fuel injection computer.

How does the engine control module ( ECM ) work?
The ECM takes the information from the engine’s various sensors, and uses that information to calculate and tune engine spark and fuel for maximum power and efficiency. The ECM plays a crucial role in newer vehicles, where many (if not all) of the essential functions of the car are controlled by the ECM.
What to do if your ECM is not connected to ignition?
Make sure that the red battery wire is connected to a battery source (It is highly recommended that this wire is connected directly to the battery) and the pink wire is connected to an ignition 1 source. If your ignition wire is not connected to an ignition 1 source your ECM will not be powered while cranking the engine. 3.
What is the result of ignition coil test?
This is the correct test result and it confirms that spark is being delivered to the distributor, but that the distributor cap is unable to distribute the spark to the spark plug wires. Also, this test confirms that the ignition coil is GOOD.
