Toyota — 2kd-ftv Ecu Pinout Diagram

The Toyota 2KD-FTV is a 2.5-liter, common-rail diesel engine found in popular vehicles like the Hilux (AN120/130), Fortuner, Innova, and Hiace. Known for its durability, the engine’s electronic control unit (ECU) is the brain behind fuel injection, turbocharging, and emissions control. Having an accurate ECU pinout diagram is essential for diagnostics, wiring repairs, ECU swaps, or piggyback tuning.

This article provides a detailed breakdown of the 2KD-FTV ECU connectors, pin functions, and practical tips for using the diagram.
