Switching Signal Circuit.

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.

How does the crank sensor control the ignition module?

The ignition module starts to turn On and Off the ignition coils in their proper firing order to create spark, after the crank signal arrives. This On/Off action is the Switching signal referred to above. Under 400 RPM’s, the ignition control module controls spark timing without the help of the fuel injection computer.

What kind of signal does the ignition module need?

OK, moving on along… for the ignition module to create this Switching signal, it needs to receive a C ran k shaft P osition (CKP) sensor signal (this signal is usually referred to as the Triggering signal and in GM service literature it’s known as the 3X or 7X CKP signal).

How does the ignition system work in a car?

When an engine starts, the ignition system operates via module timing. The engine control module signals the ignition control module, which trips a switch in the ignition control module. Activating this switch enables the primary circuit transistor to operate via signals from the engine control module.

What is the ICM in a spark ignition system?

Ignition Control Module (ICM) The ignition control module (ICM) replaced the points and condenser used in early spark ignition systems. The ICM consists of solid state technology which means there are no moving mechanical switches or parts inside the module to trigger the ignition coil.
