Where is the ignition module located in a car?
It is usually located on or in the distributor housing in domestic vehicles, and on the firewall or wheel-well in foreign vehicles. Like all automobile components, the ignition module will eventually deteriorate and break.
When does an ignition module need to be replaced?
If the light blinks, the module is good. If the light is blank or constant, the module is bad. Before you attempt to replace the control module, you must rule out other ignition system components. The module is expensive and replacing it is a laborious process. Check the ignition coil for a spark.
How can I tell if my ignition module is bad?
Connect the timer to the positive terminal of the battery and check the continuity of the black output wire while cranking the starter. If the light blinks, the module is good. If the light is blank or constant, the module is bad. Before you attempt to replace the control module, you must rule out other ignition system components.
What should I do if my ignition module is overheating?
The car may stall, which would strongly suggest that ignition control module may be the cause of the overheating you’re experiencing. If you are caught with an overheated module in an emergency situation, you can cool it down with ice water, engine coolant, or refrigerant fluid.
Where is the ignition module in a car?
The module receives a signal from a sensor inside the distributor. The signal is then used to fire the ignition coil creating the energy for the spark plugs. The ignition module may be located inside the distributor, on the distributor housing, or mounted to the side of the engine compartment.
What happens if you have a bad ignition control module?
A faulty ignition control module can cause a number of problems. 1. Check engine light is on: The ECM monitors all parts of the vehicle that could affect emissions. This includes the ignition system. If it determines the ignition module has caused a problem with the system, it will turn on the check engine light.
How does the Ignition Control Module ( ICM ) work?
If everything is working properly, the engine will start. 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).
Which is the easiest GM ignition control module to test?
This is one of the easiest GM ignition control modules to test. This article will take you step by step through the whole process of diagnosing and troubleshooting a bad ignition control module and ignition coil.
How to test Nissan Altima 2.4L ignition system?
If your Nissan Altima CRANKS but does NOT START or runs with a misfire, this is the article that will help you test and diagnose your Altima’s 2.4L ignition system (1993-1997). No expensive tools or diagnostic equipment are needed to test the ignition system, and this tutorial will show you just how to do it step by step.
What happens if your Altima ignition coil is bad?
If the Altima’s power transistor (ignition control module) or the ignition coil is BAD, then the most common symptom is that your vehicle will crank but not start and there will be no spark at any of the spark plug wires.
What to do if your Nissan Altima has a misfire?
If your Nissan Altima is suffering a misfire, the check engine light (CEL) will be on to let you know that YES, there really is something wrong (that is if your Altima is a 95-97 OBD II equipped car that’s capable of creating and storing misfire codes.). Here are a couple of other symptoms your Nissan Altima may experience with a misfire condition:
How does the PCM activate the ignition coil?
So then, after receiving the crank angle sensor signal, the PCM sends the power transistor a Triggering signal that tells the power transistor exactly when to activate the ignition coil.
