What Does A PCM Do?
Technology has taken over nearly aspect of our lives, even in our cars. The cars today have computers that help maintain better control over the car. One of the computers that are used in cars today is called the pcm computer, or powertrain control module.
The reason we have pcm's in our cars to control drive train is to help the driver maintain control of their car in different driving conditions. The sensors in the powertrain detect the road conditions, such as icy roads, wet roads, dirt roads and other others. It will send a signal to the pcm which in turn will send a signal to the parts of the drive train that it is controlling to behave in certain ways to keep the car under control.
If the car is losing traction, then it will relay the information back to a central computer that tells certain parts of the car to kick in or do things in a different way so that control is maintained. For example, it may cause the axels to each tire to turn at different speeds so that the slippage can be controlled.
The braking system is another area that the pcm has some control. Brakes can make a big difference in how a car handles on an icy or slippery road. One thing that causes problems is when someone locks up the brakes. All control is lost at that point. The pcm computer is designed to make sure that this does not happen, under normal heavy braking. It can do this by pulsing them. It can also adjust how much pressure is applied to each brake to help make sure that the car is braking in a straight line or whichever direction the driver is steering the car.
The pcm computer also controls the transmission. It has sensors to make sure that the transmission is working correctly and can also help regulate the amount of power that is passed through the transmission from the engine. Again, this is designed to help maintain control of the vehicle in all kinds of road conditions.
Like any other part on a car, the pcm computer is subject to go out. If this happens to you, it is best to make sure that you replace it soon because the car will handle much differently without it working. You can purchase pcm's new or used.
The installation of a new or used pcm computer should be done by a professional auto mechanic. It is not necessarily a difficult process, but it is possible to reconnect wires incorrectly and cause further problems that way.
The pcm is not the only computer on board. The ecm, or engine control module, controls aspects relating to the engine of the car. It controls things like fuel and air flow and spark to maximize the balance between efficiency and power. The improvement of performance, efficiency and safety are the driving factors that have led to the use of computers in our cars. - 21392

Most people do not comprehend what a pcm computer is or does and so I decided to make this post to answer some general questions about the pcm as well as help people gain an comprehending that there are other auto computers on board their vehicles.
