: Includes terminals for the Intake Air Temperature (THA), Fuel Temperature (THF), Water Temperature (THW), and Turbo Pressure (PIM) sensors.
The ECU sends low-current command signals () to an external Electronic Driving Unit (EDU) .
If the ECU loses the confirmation signal () back from the EDU, it will trigger an immediate engine shutdown to prevent fuel system damage. 2. Power and Ground Distribution
To help find the exact schematic for your specific vehicle setup, tell me: The of your vehicle? Is it an automatic or manual transmission? The part number printed on your ECU sticker?

Always outputs a regulated 5.0V to sensors.
Camshaft Position Sensor. Essential for cylinder identification.
Many 2KD-FTV ECUs feature an internal engine immobilizer linked to a transponder key amplifier. Look for pins labeled IMI (Immobilizer Input) and IMO (Immobilizer Output). If you are doing an engine swap into a different chassis, you will need the matching key chip, an immobilizer bypass module, or an unlocked ECU.
Comprehensive wiring diagrams are vital for accurate diagnostics and repairs. Reliable sources for these documents include: Full System Schematics : Detailed PDFs covering 2KD ECU and Wiring Diagrams provide wire colors and connector locations. Component Overviews : Documents like the 2KD-FTV Engine Control Overview
