Note: This pinout covers the majority of Denso 2KD ECUs. However, Toyota changes pin assignments between model years (e.g., 2005 Hilux vs 2012 Hilux). Always verify your specific ECU part number before connecting wires.

The Toyota 2KD-FTV (2.5L D-4D) engine control unit (ECU) pinout is essential for diagnosing engine management issues or performing modifications like installing performance chips. For the most accurate and safe technical work, it is highly recommended to obtain official documentation through the Toyota Technical Information System (TIS).  ECU Pinout Overview 

The 2KD-FTV ECU typically uses a multi-plug configuration (often 4 or 5 connectors) located behind the glove box. The pinout identifies the function of each terminal, including power, grounds, and sensor signals: 

Power & Ground: Pins for battery power (+B), ignition power (IGSW), and various chassis or sensor grounds (E1, E2).

Sensor Inputs: Critical inputs for the engine's Common Rail System (CRS), such as the Fuel Rail Pressure (FRP) sensor, Intake Air Temperature (IAT), and Crankshaft Position (CKP) sensor.

Actuator Outputs: Control signals for the fuel injectors, Suction Control Valve (SCV), and turbocharger wastegate or vane control.

Communication: Pins for the OBD-II diagnostic port (SIL) and Multiplex Communication Systems.  Where to Find Full Diagrams 

Because pinouts can vary slightly based on the vehicle model year and region (e.g., Hilux, Hiace, or Innova), you should refer to these specific resources:  toyota 2kd-ftv ecu pinout diagram
