2 Symptoms of a Deteriorating Ignition Module 2 Symptoms of a Deteriorating Ignition Module. The ignition module of your vehicle is the heart of your entire ignition system. 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 Is a PCM in the Engine? The module also works in conjunction with the catalytic converter to reduce the amount of pollutants expelled with the engine's exhaust and maintains the speed of the vehicle when the cruise control feature is turned on.enefits. All powertrain control modules generate a specific diagnostic code based on the vehicle component that isn't working that can then be read by an electronic diagnostic tool used by mechanics. Reading the code makes diagnosing a vehicle's problem much easier than trial and error replacement of parts.

How to Reset the Engine Warning Light on a Jeep Wrangler Sport tableau de bord image by richard villalon from Fotolia.com. A Jeep Wrangler Sport comes with a Power Train Control Module (PCM) computer on board that diagnoses problems throughout the vehicle. When the engine warning light illuminates on the instrument panel, this is the result of a trouble code sent to the PCM. You can take the vehicle to an auto parts store to have it diagnosed for free, and then you should have the problem fixed by a mechanic.

- Modern Electronic Ignition Modules. For the most part, there are 2 types of ignition systems in use today (or variations of them): Induction ignition (TCI=Transistor Controlled Ignition) or CDI (Capacitive Discharge Ignition). Both systems use a sensor (discussed above) to trigger a transistor switch (which has replaced the points).
