⚠️ Warning: Modifying signals can cause engine damage. Always use a tuner experienced with common-rail diesels.
This short paper documents the engine control unit (ECU) connector pinout for the Toyota 2KD-FTV diesel engine (commonly used in Toyota Hilux, Innova, Fortuner, and related models). It summarizes pin functions, signal types, and wiring notes helpful for diagnostics, sensor replacement, and aftermarket ECU interfacing. This is for technical reference only — confirm pin numbers against the vehicle's service manual and wiring diagrams before connecting.
The Ultimate Guide to the Toyota 2KD-FTV ECU Pinout Diagram The Toyota 2KD-FTV is a 2.5-liter, four-cylinder, turbocharged diesel engine. It powers popular vehicles like the Hilux, HiAce, Fortuner, and Innova. Known for its reliability, this Common Rail Diesel Injection (CRDi) engine relies heavily on its Engine Control Unit (ECU) to manage fuel delivery, injection timing, and turbo boost.

Whether you are performing an engine swap, diagnosing a electrical fault, or installing an aftermarket performance module, understanding the is essential. This article provides a comprehensive breakdown of the 2KD-FTV ECU architecture, connector configurations, and critical sensor wiring. 1. Overview of the 2KD-FTV ECU System
Toyota ECUs across the 1KD-FTV and 2KD-FTV families generally utilize a multi-plug configuration, often consisting of 4 or 5 distinct plastic connectors labeled alphabetically (e.g., Connector A, B, C, D, E) or by their total pin counts (e.g., 34-pin, 35-pin, 24-pin, 31-pin). How to Read the Pin Numbers
Most late-model 2KD-FTV ECUs require an immobilizer key amplifier module signal via the IMI and IMO pins. If your donor package lacks the matching key and transponder chip, the engine will start for 2 seconds and die. You will need an immobilizer delete service or a matching key set.
