How does the ignition control module work on an engine?
The ignition control module converts the analog signal into a digital signal, which essentially is used as an on/off switch by the ignition control module. When an engine starts, the ignition system operates via module timing.
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.
Where is the ignition coil on a car?
by Andrea Stein. An ignition coil is the coil in a vehicle’s ignition system used to convert sufficient voltage to spark the spark plugs. The ignition control module helps manage the electrical current used by the ignition coil. The ignition control module typically mounts on the engine.
What makes a car have an ignition system?
While the automotive industry has achieved drastic mechanical and technological advancement throughout history, there’s one component that all cars with combustible engines have in common: the ignition system.
What is the main purpose of the ignition module?
An ignition module is the component in electronic ignition systems that functions as the contact breaker for the coil or coils. In most basic terms, an ignition module is an electronic replacement for old, mechanical contact breakers like ignition points.
What causes an ignition control module to go bad?
Ignition control modules can, and often do, go bad on all makes and models of automobiles. Causes of faulty ignition control modules include: An internal short. Wire short. Poor electrical connections at the spark plug. Failure. Overheating.
What are the symptoms of having a bad ignition control module?
- vibrate or jerk when the gas pedal is pressed. There may be hesitation or lack of power during increases in speed.
- Temperature Problems. A faulty ignition module can cause a vehicle to overheat.
- No Power. The engine may turn over without starting.
How do I test ignition module?
To test, use a voltmeter to check for power at the control module with the ignition on. If there is power, crank the engine and check for a pulsating ground at the module. This pulsating ground is a signal from the car’s computer. If there is no signal, the problem is with the computer or a sensor.
