Engine Control Module (ECM)

ECM receives and processes signals from input devices. Operating conditions such as cold starting, altitude, acceleration and deceleration affect input device signals. Based on signals received, ECM sends signals to various components, which control fuel injection, ignition timing, idle speed and emission control systems. For ECM location, see ECM LOCATION  table.
