An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
A PCM from a 1996 Chevrolet Beretta. A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller 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 ...
An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

The Problem Solving Environment (PSE) released a few years after the release of Fortran and Algol 60. People thought that this system with high-level language would cause elimination of professional programmers. However, surprisingly, PSE has been accepted and even though scientists used it to write programs. [2]
The new Cherokee (KL) is built on the compact U.S. wide platform, and features a nine-speed automatic, a choice of a 2.4 L Tigershark I4 with Fiat's electro-hydraulic MultiAir 2 variable valve timing and variable valve lift or a 3.2 L V6 based on the Pentastar 3.6 L V6, and front and four-wheel drive (the latter a Jeep's Selec-Terrain system).

The Jeep Compass is a compact crossover SUV [3] [4] introduced for the 2007 model year, [5] and is currently in its second generation. The first generation Compass and Patriot , its rebadged variant, were among Jeep 's first crossover SUVs.
In Mode A, pins 1 and 2 (pair 3 in T568A wiring, pair 2 in T568B) form one side of the 48 V DC, and pins 3 and 6 (pair 2 in T568A, pair 3 in T568B) form the other side. These are the same two pairs used for data transmission in 10BASE-T and 100BASE-TX, allowing the provision of both power and data over only two pairs in such networks.
