Crucial for timing; 2KD uses a 34-2 tooth trigger wheel.

Signals sent to the EDU to trigger individual fuel injectors.

It is important to note that pinout locations can vary based on the and vehicle model (e.g., Hilux vs. Hiace). For example, updates in 2005 introduced the 3rd generation Common Rail System with higher injection pressures, which may feature different ECU terminal layouts compared to the original 2001 versions.
