Where is the electronic spark control module?
Where is my ignition control module located? The Ignition Control Module (ICM) is located in the distributor housing near the ignition coil. To access the module, remove the distributor cap, rotor, and if equipped, the dust cover.
What does the electronic spark control module do?
One of these components is the electronic spark control module, commonly referred to as the ESC module, or the ignition module. The ignition module works together with the computer to time the engine’s ignition system for the best performance and efficiency. One of the specific functions of the ESC module is to advance or retard the timing…
Can a bad ESC module cause no spark?
Another common symptom of a faulty ESC module is a no start, or no spark condition. The ESC module is one of the components that directly controls engine spark, so if it fails, it can leave the vehicle without spark.
How does the ignition control module ( PCM ) work?
Now, the important thing to know is that the PCM controls the creation of spark from the get-go (crank up) and at all engine speeds thru’ the ignition control module (ICM). The really cool thing about this type of ignition system is that all of these signals ( IC Signal and the Switching Signal) can be tested easily with some very simple tools.
Can a GM ignition control module be used?
The ignition control module (ICM) and ignition coil tests in this article assume that your vehicle is Cranking but NOT STARTING due to a NO SPARK Condition. If you’re GM car or truck starts and runs, this article will not help you.

How does the ECM bypass the ignition module?
When the engine speed exceeds 400 RPM, the ECM sends a BYPASS signal to the ignition module which switches the timing to ECM control. The ECM calculates what the timing should be then “tells” the ignition module via the EST circuit. An open or ground in the EST circuit will stall the engine and set a Code 42.
