An ICM is nothing more than a switch that transforms the ignition device “On” or “Off”. Inside of the distributor there is a sensor that sends out out a signal to the ICM, which is then supplied to fire increase the ignition coil that will produce enough energy for the spark plugs. The spark have to be solid enough to connect the gap in between the spark plugs,therefore producing enough voltage to ignite the fuel/air mixture for a fine timed combustion. The ignition regulate module must control the time of the spark so the it is able to occur specifically at the best cylinder and also the perfect moment. If girlfriend would favor to know more about the ignition procedure you deserve to do so by analysis our following post.

You are watching: Where is the ignition module located


How to determine the Ignition manage Module.

The ICM place varies indigenous make, to models and also of food to the year the vehicle was built. Please keep in mind that part cars can not have actually a different ICM but is instead regulated by the Engine regulate Module (ECM) which goes by various names such together the Powertrain manage Module( PCM) / Engine control Unit (ECU). Before going ahead and look because that it. Fire up your search engine and find out whether you have an incorporated Electronic Ignition mechanism so you won’t finish up analysis this since it won’t it is in of any type of use.

Typically the Ignition control Module is located inside that the distributor real estate or mounted on the next of the engine compartment. Not to state the obvious, but once one engine module goes negative your vehicle will no run in ~ all, yet luckily you can fix that v the simplest of tools and also in 3 simple to monitor test.

experimentation an Ignition module is straightforward so, right here is what girlfriend will require

A wiring chart of her vehicle(which have the right to be found online)Wire Piercing probesA helper(to crank the engine)A 12 volt test lightA replacement ignition switch**

As girlfriend can an alert this list is an easy and perfect if you’re make the efforts to work-related with a budget.


Step 1 : Check your ICM for current.

Using the an unfavorable lead of your DVOM( Digital Volt Ohm Meter ) ground it to the vehicle’s steel frame. PS : the MUST be grounded turn off a metal part of the car. Now have your helper crank the engine when you’re trial and error the different terminals for current. If there is no present being passed to the terminals i m so sad you will need to replace the entire ignition regulate module.

Step 2 : Check her ICM Spark Plugs ( ignition module ) because that current.

To examine the spark plugs because that current, you will certainly grab her 12v test light and also tap into your spark plugs terminals. If her test flickers constantly once you crank the engine then you have the right to go ahead and note that your plugs room in great working conditions. Now the problem is you will should run a much an ext thorough test for the other components in your vehicle. No current? keep reading.

Step 3 : Isolate the problem.

You have had no current, currently what? We’re walking to have actually to check for continuity. I usually begin by inspecting every wires for indicators of break,burnt marks or any kind of sorts that fraying these are usually the tell-tale signs.

Using her DVOM test switch to the OHMS setting and closely retest the ICM wires again. Make certain you are experimentation the wires going from/to the ignition manage module and spark plugs. If you room still gaining an infinite reading off her DVOM climate you deserve to go ahead and conclude that your wires space faulty.

Once you’re done if it’s the wires that demands to be changed it won’t be too much of a hassle to repair however you can end increase needing the aid of a standard mechanic or you can quickly do it you yourself if you’re up for the challenge. Currently if that is no a wiring worry or not an ignition coil issue and you’re in require of an ignition manage module, you’re in luck since here in ~ Flagship One we carry the nation’s biggest inventory of ignition manage module and far better yet we have the most reasonable prices so be sure to check out our store or just provide us a contact at516-766-2223.Ourexpertsareheretohelp!


deserve to you test an ignition control module?

Yes, girlfriend can certainly test one ignition manage module and using a multimeter is just one of the fastest method to do so.

What walk the ignition control module do?

The Ignition control Module or ICM is nothing much more than a switch per se that transforms the ignition mechanism “On” or “Off”.

just how do you check an ignition regulate module in GM?

Step 1 : examine your ICM because that current. Step 2 : Check your Spark Plugs ( ignition module ) for current. Step 3 : isolation the problem.

how do I recognize if my ignition manage module is bad?

if you space not getting any current come or from your ICM your ignition control module is bad. Read our post and also use a multi meter
