A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the Transmission Control Unit, and the Body Control Module, for a total of three separate computers as an example. These automotive computers are generally very reliable. The PCM commonly controls more than 100 factors in a car or truck.
ECM. Some of older automobile models had two computers, the ECM and the TCM. The ECM controlled the engine function, but the transmission was controlled by a different computer system called the transmission control module, or TCM.CM. The PCM is the main computer in the automobile that controls all the functions of the vehicle. Everything from the vehicle's timing to the proper flow of fuel into the fuel injection system is under the control of the PCM.
