I cannot directly provide a full pinout diagram for the Toyota 2KD-FTV ECU as an image, but I can give you the most detailed, accurate text-based pinout for the common Denso ECU (usually part numbers like 89661-0K... or 89661-0L...) used in the Toyota Hilux, Fortuner, Innova, and Hiace equipped with the 2KD-FTV engine (Euro 3 & Euro 4 variants).
Here is the better organized pinout you asked for – grouped by function, not just raw pin numbers.
The Denso ECU on the 2KD-FTV typically uses four main connectors (A, B, C, D). Depending on your vehicle (Hilux AN10/AN120, Fortuner AN50, Innova AN40), the pin count varies: toyota 2kdftv ecu pinout diagram better
Critical Warning: Always verify your ECU part number. The most common 2KD ECUs are
89661-0K...or89661-0K1.... Pins A15 and B17, for example, swap roles between Euro 3 and Euro 4. Never trust a pinout without confirming your ECU ID.
If you cannot communicate with the ECU, check these first. I cannot directly provide a full pinout diagram
| Pin Number (Approx) | Function | Description | | :--- | :--- | :--- | | E2-1 | Battery Positive (+B) | Constant 12V from Main Relay. | | E2-2 | Battery Positive (+B2) | Constant 12V from Main Relay. | | E2-3 | Ground (E01) | Power Ground. Connects to Engine Block. Critical for injectors. | | E2-4 | Ground (E02) | Power Ground. Connects to Engine Block. Critical for injectors. | | E1-xx | Sensor Ground (E1) | Signal return ground (0V reference for sensors). |
The 2KD-FTV often uses a VNT (Variable Nozzle Turbo) which requires an Electric Vacuum Regulating Valve (EVRV). Detailed Pinout – Most Common 2KD-FTV (Euro 3/4,

Pro Tip: The SCV (Suction Control Valve) at pins A13/A14 is notorious for failing. If your 2KD accelerates poorly or surges at idle, back-probe these pins for a clean 12V PWM signal (about 5-7 kHz frequency).
