🔌 Function

The ECU is the main engine-management module. It receives signals from the crank, throttle, temperature, knock, MAP, oil-pressure and other engine sensors, then controls fuel injection, ignition timing, idle strategy, guardian functions and diagnostic fault storage.

⚠️ Common Signs of Failure

• No-start condition with correct fuel pressure and ignition inputs
• No communication with diagnostic equipment
• Intermittent stalling or loss of injector pulse
• Engine running excessively rich or lean despite correct sensor inputs
• Fault codes that return after wiring, sensor and power-supply checks
• Ignition or fuel-control faults isolated to the ECU after testing
• Poor idle quality or limp-mode operation caused by internal module failure
