    • Works with the fuel rail pressure sensor and injectors.
  2. Turbocharger & Boost Control

    • Adjusts variable-geometry turbo (VGT) operation for efficiency.
    • Monitors boost pressure sensors.
  3. Exhaust Gas Recirculation (EGR) System

    • Reduces NOx emissions by recirculating exhaust gases.
  4. Diesel Particulate Filter (DPF) Monitoring

    • Controls DPF regeneration cycles and monitors soot levels.
  5. Idle Speed & Engine Load Regulation

    • Ensures stable idle speed under different conditions.
  6. Glow Plug & Cold Start System

    • Manages glow plugs for better cold starts.
  7. On-Board Diagnostics (OBD-II) & Emissions Control

    • Monitors sensors and stores Diagnostic Trouble Codes (DTCs).
  8. Communication with Other Modules (CAN Bus)

    • Interacts with ABS, traction control, transmission, immobilizer.

2. ECU Installation Process

Pre-Installation Precautions

  • Disconnect the Battery before handling the ECU to prevent damage.
  • Match ECU Part Number to avoid compatibility issues.
  • Use Anti-Static Protection (ESD strap) to prevent static discharge.

Installation Steps

  1. Locate the ECU:

    • Typically found under the dashboard or near the engine bay.
  2. Remove the Old ECU:

    • Disconnect wiring harness connectors carefully.
    • Unscrew and remove the ECU from its mounting bracket.
