What happens when the control module goes bad?
by Marcus Baker. The control module of a vehicle is basically the computer that does the thinking for an engine’s control system. It affects the functioning of things ranging from a vehicle’s charging system to its transmission. This is why when the control module goes bad, the engine suffers functionality issues as well.

What is the role of the ignition module?
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.
Why is my ignition module not working properly?
It’s also possible the circuits may be critically damaged by overheating if the problem is not addressed after the first or second occurrence. If you cannot start the car, you need to test the ignition control module using a light timing tester to check the output of the module.
What causes a HEI control module to keep going out?
This a late 70’s early 80’s Large Cap HEI SBC with 4 pin Ignition Control Module. What would cause the module to keep going out? It only last a few months.
What are the symptoms of a bad engine control module?
1. Check Engine Light Turns On 2. Engine Stalling or Misfiring 3. Engine Performance Issues 4. Car Not Starting 5. Poor Fuel Economy The engine control module (ECM), also commonly referred to as the engine control unit (ECU) or powertrain control module (PCM), is one of the most important components found on virtually all modern vehicles.
How does the engine control module ( ECM ) work?
The ECM takes the information from the engine’s various sensors, and uses that information to calculate and tune engine spark and fuel for maximum power and efficiency. The ECM plays a crucial role in newer vehicles, where many (if not all) of the essential functions of the car are controlled by the ECM.
