ECU (Engine Control Unit): This is the brain of your car's engine management system, controlling various functions such as fuel injection, ignition timing, and emissions.
PCM (Powertrain Control Module): A more advanced version of the ECU, the PCM oversees not only the engine but also the transmission, ensuring optimal performance of the powertrain.
ECM (Engine Control Module): Similar to the ECU, the ECM focuses on engine-related functions, monitoring sensors and adjusting settings to maintain efficiency.

Understanding the roles of these modules will help you troubleshoot any problems that arise with your vehicle's performance.

ECM: The ECM is similar to the PCM but may have a narrower focus on engine-related functions. It monitors and controls various engine parameters to ensure optimal performance and efficiency.
