How to Troubleshoot ECU, PCM, and ECM Problems
If you suspect an issue with your car's control module, here are a few steps you can take to troubleshoot the problem:

The ECU, or Engine Control Unit, is responsible for controlling various engine functions, such as ignition timing, fuel delivery, and emissions systems. It plays a crucial role in optimizing engine performance and improving fuel efficiency.

The Powertrain Control Module (PCM) is an advanced version of the ECU, encompassing broader control over the powertrain system. In addition to managing the engine, the PCM oversees the transmission, emissions, and other critical systems. By integrating multiple functions into one unit, the PCM enhances efficiency and performance in modern vehicles.

The ECU is the brain of your car, monitoring and controlling engine functions such as fuel injection, ignition timing, and emissions. It collects data from various sensors to make real-time adjustments for the engine to operate efficiently.

The Engine Control Unit (ECU) is a fundamental component of modern vehicles, responsible for managing the engine's performance. It controls various functions, including fuel injection, ignition timing, and idle speed. Essentially, the ECU acts as the brain of your car, monitoring and adjusting parameters to ensure optimal operation.
