What does a distributor Control Module do?

What Is an Ignition Control Module? Many older vehicles use a stand-alone ignition control module. It is responsible for switching the ignition coil(s) on and off to fire the spark plugs. This is crucial, as the engine can’t run properly unless every spark plug is fired at exactly the right time.

What are the symptoms of a bad distributor control module?

Symptoms of a Bad or Failing Electronic Spark Control

• Engine performance issues. One of the first symptoms of a problem with the ignition module are engine performance issues.
• Engine stalling. Another symptom of a problematic ESC module is the engine stalling.
• Car not starting or engine not sparking.

What happens when your ignition control module goes bad?

A faulty ignition module can affect ignition timing, resulting in an engine that misfires and runs rough. The engine may also run well at low speed, but won’t accelerate well. 3. Stalling: A failing ignition module can occasionally prevent the engine from getting spark, causing it to stall.

What does an ignition control module look like?

What does a Ford Ignition Control Module do?

It controls th ignition coil’s firing time. The ignition control module is the heart of an automobile’s ignition system. It regulates spark generation within the engine.

How do you test a coil module?
