What is ECM called?
An engine control unit (ECU), also commonly called an engine control module (ECM) is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance.
What’s the difference between a PCM and ECM in a car?
As their names indicate, the ECM would control the engine while the TCM monitored and provided input to the transmission. As technology improved, automotive manufacturers began to combine the two computers into a single, efficient unit — the PCM or powertrain control module.
What are the symptoms of a damaged ECM?
Like any other computer or mechanical system, a damaged ECM or PCM will display a few symptoms. 3 of the most common include: 1. Inconsistent engine operation: The ECM and PCM control engine functions that must work together to efficiently burn fuel.
