The ignition control module holds a paramount position amidst the other parts of an internal combustion engine. It is the brain that controls the ignition timing and spark generation, enabling the air-fuel mixture to burn. That said, without an ignition control module, the proper ignition will be impossible, resulting in inefficient engine performance. Moreover, it will also disrupt the fuel consumption of a vehicle. <\/p>\n\n\n\n

Let\u2019s dive a little deeper and dissect the working, types and other details regarding the ignition control module. <\/p>\n\n\n\n

How Does an Ignition Control Module Work<\/h2>\n\n\n\n

The ignition control module is the part of the car’s ignition<\/a> system that is responsible for generating a spark, igniting fuel inside combustion chambers and starting the vehicle. In the ignition system, a number of components work in synchronisation, including the ignition control module. <\/p>\n\n\n\n

Amidst these components, the function of ignition of the ignition control module is to generate spark and control ignition timing. In the first step, the module receives information regarding the engine’s rotational speed and position. The information is collected and transferred through different car sensors, including crankshaft position sensors<\/a>. <\/p>\n\n\n\n

After processing the information, the ignition control module signals the ignition coil to generate high-voltage current and distribute it to the spark plug<\/a>. The spark plug is then used to ignite the air-fuel mixture inside the combustion chamber. <\/p>\n\n\n\n

Ignition Control Modules Types<\/h2>\n\n\n\n

Now that you are aware of the functions of an ignition control module, let\u2019s move toward the different types used in cars. <\/p>\n\n\n\n

Mechanical Ignition Control Module<\/h3>\n\n\n\n

The mechanical ignition control module is the earliest form of module used in cars. As evident from the name, these modules were mechanically operated and used points and different components to generate electrical signals. That said, the involvement of too many mechanical parts makes it prone to wear and tear. Moreover, it also requires regular maintenance to ensure smooth functioning. <\/p>\n\n\n\n

Electrical Ignition Control Module<\/h3>\n\n\n\n

Since there have been multiple issues with the mechanical ignition module, it was replaced with the electrical one. The electrical module system uses solid-state electronics to signal the ignition coil. That said, the electrical module consists of an integrated circuit, transistors, capacitors and other components to manage the ignition system. <\/p>\n\n\n\n

Contrary to the mechanical one, the electrical module is more reliable, durable, efficient and provides precise information, resulting in better engine performance. <\/p>\n\n\n\n

Two different types of ignition control modules are present in the cars. Generally, modern cars have an electrical ignition module<\/figcaption><\/figure>\n\n\n\n

Bad Ignition Control Module Symptoms<\/h2>\n\n\n\n

In case of an ignition module failure, the engine dies and will not restart. However, the failure of the ignition module is generally caused due to overheating and is often misdiagnosed. Following are some common symptoms that indicate a malfunctioning ignition control module. <\/p>\n\n\n\n

Engine Stalling & Misfiring<\/h3>\n\n\n\n

The first symptom of a failing ignition control module is engine stalling and misfiring which indicates incomplete combustion. Moreover, it will also cause difficulty in acceleration; the car will start shaking or jerking whenever the accelerator pedal is pressed. <\/p>\n\n\n\n

Dead Engine<\/h3>\n\n\n\n

The car starts for a second and then dies<\/a> is another common symptom of a failing ignition module. In some cases, the engine will be completely dead and will take several attempts to restart. It generally happens due to the corroded electrical connections of the ignition module. It can be fixed by cleaning the connection, repairing the switch, or replacing the wires, if needed. <\/p>\n\n\n\n

Engine Check Light Illuminated<\/h3>\n\n\n\n

The check engine light is illuminated when the ignition module malfunctions. However, the engine check light can be illuminated due to multiple other reasons. To identify the potential cause of the light turning on, you can use the OBD Scanner<\/a>. <\/p>\n\n\n\n

Ignition Control Module Test<\/h2>\n\n\n\n

Once your vehicle starts showing the above-mentioned symptoms, it’s recommended to get your ignition control module replaced. However, you can also check its functioning at home prior to visiting the mechanic. Here are the steps to test a bad ignition control module at home. <\/p>\n\n\n\n
