How does the ignition control module work in a car?
How does the ignition control module work in a car?
Basic Theory: How The Ignition Control Module Works. In a nutshell, the ignition control module’s job is to create a Switching signal for the ignition coils that are sitting on top of it. It’s this Switching signal that makes the ignition coils create spark.
How to troubleshoot an automotive engine high idle?
The troubleshooting procedure for high and low idle conditions are similar, which are included in the following: Step 1 – If the check engine or service engine light soon has illuminated retrieving the diagnostic trouble codes could lead you in the right direction of what the problem is, or is related too.
Is there a spark in the ignition module?
There is no spark coming out of any of the ignition coils sitting on top of the ignition module. You may have taken your ignition control module (ICM) to Auto Zone to test it and the friendly boys in orange say it’s good, yet the vehicle will not start (all major auto parts stores such as O’Reilly, Pepboys, etc., test ignition modules for free).

If you cannot start the car, you need to test the ignition control module using a light timing tester to check the output of the module. Connect the timer to the positive terminal of the battery and check the continuity of the black output wire while cranking the starter. If the light blinks, the module is good.
What is the role of the ignition module?
Its two main roles are to create a spark strong enough to ignite the air/fuel mixture for combustion and to control the timing of the spark plugs by opening and closing the ignition coil ground circuit. The ignition module has a direct impact on the performance of the engine.
What happens when an ignition module overheats?
Ignition modules that are overheating will soon completely cease to function and in the meantime can cause cause electrical shorts, engine stuttering, lower gas mileage, power loss, stalling, and gasoline odors in the exhaust.
What is the role of the ignition coil?
Its two main roles are to create a spark strong enough to ignite the air/fuel mixture for combustion and to control the timing of the spark plugs by opening and closing the ignition coil ground circuit.
