A: In most Hilux and Fortuner models, the ECU is typically located behind the glovebox, inside the passenger compartment. In the Hiace, it's often behind a trim panel on the passenger side of the engine bay.
The 2KD-FTV ECU uses a grid system of rows and columns to index pins. The connections break down into four primary operational groups. 1. Power Supply and Ground Circuit toyota 2kdftv ecu pinout diagram better
