The ignition control module is a crucial component of a vehicle's ignition system. It is a control unit responsible for regulating the ignition timing and generating sparks to ignite the fuel-air ...

Q: My 2002 Buick LeSabre has 98,887 miles on it. Its ignition control module is failing. Since November 2014 I have replaced it three times. Can you please tell why my control module keeps failing ...

The engine control module (ECM) is known by many other names, including the engine control unit (ECU). Whatever it is called, it has the same function. This vital component sends messages to the motor ...

The Electronic Control Unit (ECU, an early ECM) handles coil control via the ignition module. Coil output is routed via a conventional ignition wire to the distributor, where it is fed to the six ...

Also, improvements can be made to the design of ignition control module, so the unit is able to withstand greater levels of heat and vibration.

Typically, when an ignition control module of this type fails it would be one of the three drivers (transistors) within it that controls a specific ignition coil giving up.

High energy ignition systems use a transistorized switch within an ignition module that also handles the task of triggering the ignition coil to generate high-voltage current.
