What is an ECU Fault Code Retrieval, PCM, and ECM?
Electronic Control Unit (ECU) is a generic term describing any embedded system that controls one or more of a vehicle's electronic systems.

It might be time to check your car's Engine Control Unit (Aftermarket ECU Upgrades), also known as the Powertrain Control Module (PCM) or Engine Control Module (ECM).

The Engine Control Unit (ECU Fault Code Retrieval) is a crucial component of modern vehicles that controls various aspects of the engine's operation, such as fuel injection, ignition timing, and emissions.
