What is PCM and ECM?
ECMs (Engine Control Module) and PCMs (Powertrain Control Module) are used in the same parts of the engine: the computing module. The main difference between the two is that the ECM controls specific parts of the engine, regulating and sending commands.
What is a computer PCM?
A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. The PCM is one of potentially several on-board computers, or essentially the “brain” of the engine control system.
What’s the difference between an ECM and a PCM?
The terms “ECM” and “PCM” are used interchangeably when referring to engine electronics, but there is a difference between both units. An “ECM” is an Engine Control Module, sometimes referred to as an “ECU,” or Engine Control Unit. This computer takes incoming sensor data to alter the function of electronic systems.
Can a PCM ECM be rebuilt at solo?
Here at Solo, we rebuild auto computers such as PCM, ECU, ECM, and TCU. We can refurbish and rebuild just about any PCM, ECM, or ECU auto computer. Currently, we service the ECM, ECU, and PCM auto computers for, Dodge, Cadillac and Chrysler PCM, ECM ECU. Additionally, we can service the Jeep PCM.
What was the purpose of the first ECM?
An “ECM” is an Engine Control Module, sometimes referred to as an “ECU,” or Engine Control Unit. This computer takes incoming sensor data to alter the function of electronic systems. The first ECMs introduced in the early 1980s could only control fuel injection, but as electronics and engine design have improved,…
What does the PCM do in a corvette?
For example, the Active Rev Matching in a Corvette matches clutch and engine RPM during shifts using wheel speed data from the traction control system and a shifter position sensor on the transmission. The PCM (Powertrain Control Module) is the main computer in the automobile that controls all its functions.
What are the signs of a bad ECM?
Bad ECM symptoms includes a sudden shift in gears during automatic transmission. With failure in the sensors and communication between the module and the engine, the vehicle would end up jerking.

What is the difference between an ECM and ECU?
ECM is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. ECU, which is also known as the powertrain control module (PCM), controls a series of actuators to make sure things are running smoothly within the engine.
Where is my ECM?
The location of the ECM depends on the make and model of the vehicle. In most vehicles, the ECM is located in the engine compartment. Some vehicles have the ECM mounted under the driver’s or passenger seat, however. Open the engine compartment to access the battery.
