An ignition control module (ICM) is one of the key parts of your car’s engine. It helps to manage the fuel and spark for your engine, ensuring that it starts properly each time you drive. If your ICM fails, it can cause problems with your car’s ignition system, leading to a number of dangerous consequences. In this article, we will teach you how to test an ICM and identify any problems before they cause too much damage.
What is an ignition control module?
An ignition control module (ICM) is a component of an automobile engine that controls the firing of the spark plugs. An ICM malfunction can cause stalling, misfires, and reduced fuel efficiency. The most common symptom of an ICM failure is a “check engine light” (“CEL”).
How do I test an ignition control module?
If you’re having trouble starting your car, or it’s been giving you problems lately, it might be time to check your ignition control module. This small, computer-controlled device helps to start the engine by controling the flow of gas and oil to the engine. If there’s a problem with the module, it could cause your car to be difficult to start or not at all. Here’s how to test an ignition control module:
1. Remove the key from the lock cylinder.
2. Turn the car off by pressing down on the fuel pump switch until it clicks into position (it may take several seconds).
3.Remove the battery cable if there is one. Place a jumper cables across both terminals at either end of the Module (see picture).
4. Turn on the car by holding down on fuel pump switch and turning key until headlights come on then release fuel pump switch. The Module should fire up shortly after and should idle within specifications (check manual). If not, replace Module
What if I find a problem with my ignition control module?
If you find a problem with your ignition control module, there are a few things you can do to check the module and fix it. First, you can try to start the car using the key in the “On” position. If it starts but doesn’t work properly, the first thing you should do is check your battery cables and connections. This is especially important if you’ve had problems with your car starting in the past. Next, you can try to reset the module by disconnecting all of the connectors and re-connecting them one by one in sequence. Finally, if none of these options work, you’ll need to take your car into a mechanic for repair.

If you are having trouble starting your car, or if the engine just won’t turn over, you may need to check your ignition control module. This is a relatively easy task that can be done in just a few minutes using basic automotive tools. Following these steps should help you get your car started in no time.
