2. Electronic control unit - Wikipedia

   en.wikipedia.org/wiki/Electronic_control_unit

   An ECU from a Geo Storm. 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.

3. Powertrain control module - Wikipedia

   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 ...

   It is likely that more Ford vehicles were produced using Engine/Powertrain Control Modules (ECM/PCM) based on variations of this design than any other module that Ford has ever used. Unlike previous EEC systems, EEC-IV uses a small ignition module called the TFI or TFI-IV (Thick Film Integrated Ignition) module.

5. On-board diagnostics - Wikipedia

   This interface was made in different varieties and changed with power train control modules (aka PCM, ECM, ECU). Different versions had slight differences in pin-outs and baud rates. Earlier versions used a 160 baud rate, while later versions went up to 8192 baud and used bi-directional communications to the PCM. [15] [16]

6. Transmission control unit - Wikipedia

   en.wikipedia.org/wiki/Transmission_Control_Unit

   A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in conjunction with various semi-automatic transmissions, purely for clutch automation and actuation.

7. Automotive electronics - Wikipedia
