🔌 Function

The ECM controls engine-management functions including fuel injection, ignition timing, idle speed control, sensor monitoring, diagnostic fault storage and engine-protection response.

Common signs of failure:

• No-start with confirmed fuel pressure, crank signal and ECM power supply

• No injector command or no ignition output after harness testing

• No diagnostic communication

• Intermittent engine shutdown or limp-mode activation

• Persistent ECM fault codes after sensor and wiring checks

• Rich, lean or unstable running caused by incorrect ECM output

• Voltage damage, water ingress or corrosion at ECM connectors

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
