The control module of a car controls the engine's mixture of ingredients that are used to make energy, which are fuel, air and spark. It is able to do this by constantly monitoring the car's network of sensors to make sure that conditions are within the standard operating range.


A body control module, or BCM, coordinates different operations within a car through the use of signals. Every electrical part of modern cars, from the door locks to the headlights, is controlled by a BCM.


The body control module in a car is generally located underneath the car's center console or behind the glove compartment. If the body control module is not here, the car's owner's manual provides the location.


When attempting to repair a body control module, first check the vehicle's fuses. If any appear blown, replace them. If problems persist, take the vehicle to an automobile parts store with diagnostic testing capabilities to determine if it is indeed the body control module. Depending on the results


An engine control module is a device that monitors a network of sensors in a car and performs necessary adjustments to the conditions when they are outside of the normal operating range. The module stores a code whenever it encounters a problem, allowing a mechanic to scan it later.


An electronic control module is a small electrical component that controls and monitors a number of actuators inside a vehicle's engine. It is often referred to as the brain of an engine, and it dynamically regulates air and fuel mixture, idling speed and ignition timing to ensure ideal engine opera


A transmission control module is a mechanism that regulates a vehicle's automatic transmission by processing electrical signals. Sensors electronically send information to the transmission control module, and this information is used to calculate gear shifting. The transmission control module helps


When the engine control module begins to fail, a car may have difficulty starting, the "Check Engine" light may come on, the gears may have difficulty shifting, fuel efficiency may decline and the car's engine may run poorly. If you do not replace the module, the symptoms continue and eventually the


In education, a "module" is a fractional part of a student's education experience. In an entire degree program, each class represents a module focused on a given subject. In a single class, a module is a chapter, class meeting or lecture on a specific topic.


An ignition control module is a component in a vehicle's engine that enables a spark to be produced at the correct time in each cylinder. It does much the same job as contact breaker points did in older cars.
